Installation requirements of steel plastic composite pipe

The steel plastic composite pipe is cut with a grinding wheel cutting machine. After the pipe is cut, the pipe orifice shall be polished to remove burrs and flash. Electric threading machine shall be used for pipe thread processing. In the threading process, oil shall be often added for lubrication and cooling. The pipe thread shall form a conical shape. The thread shall be straight and clear without burrs. The total length of disordered wire, broken wire and missing wire shall not exceed 10% of the full length of the thread. After threading, the pipe orifice shall be cleaned immediately, and the burrs on the end face of the pipe shall be treated to keep the pipe orifice smooth. The broken wire and missing wire shall not be greater than 10% of the total number of threads. Generally, conical external thread connection is adopted for pipe thread connection, and hemp wire and white lead oil are used for connecting pipe joint filler. Screw tail shall be reserved after tightening, and generally 2-3 threads shall be reserved. The packing shall be properly wound. White lead oil and hemp wire shall not be sagged from the pipe end and squeezed into the pipe cavity to avoid blocking the pipeline. All kinds of packing can only be used once in the thread. If the thread is disassembled and reassembled, the packing shall be replaced. Suitable pipe tongs or chain tongs shall be selected for threaded connection. It is not allowed to add casing on the handle of pipe tongs or chain tongs to increase the handle to tighten the pipe. Whether the pipes are bent shall be checked by visual inspection or rolling method. The pipes with multiple bends shall be flattened one by one. The bending of large-diameter pipes can be straightened by Jack, and thermal straightening is strictly prohibited. It can be seen that the installation requirements of steel plastic composite pipe are very simple, but more attention should be paid to the installation of steel plastic composite pipe.

Performance introduction of various industrial pipelines

Time of issue: : 2022-01--07
There are many kinds of pipes used in industrial production, especially in the chemical field. In the modern society with the continuous development of the chemical industry, people still have a large demand for industrial pipelines, and chemical pipelines with different properties need to be selected on different occasions. In this regard, we need to know the performance of various industrial pipelines in advance. Next, Xiaobian will introduce you to several common industrial pipelines and their performance, so that you can focus on selecting industrial pipelines in the future. Ordinary steel pipe: the pipe made of ordinary steel is generally simple in structure, single in performance, but low in cost. Ordinary steel pipes also have strong mechanical strength, but they are prone to corrosion and corrosion after long-term use. Plastic lined composite pipe: the so-called plastic lined composite pipe is actually adding an upper layer of plastic material inside the steel pipe as a means of protection. Because the chemical stability of plastic material 1 is much better than that of metal and has excellent anti-corrosion performance, it is said that the plastic lined composite pipe is not easy to corrode and rust and has a longer service life, but the counterfeiting is higher. Bimetallic tube: a bimetallic tube can be formed by sampling multi-metal structure for mixed assembly. The counterfeiting of bimetallic tube is relatively high, but it is extremely excellent in heat resistance and pressure resistance, and is not prone to institutional damage. Stainless steel pipe: This is an industrial pipe using stainless steel as the main material. Because the stainless steel material itself has good properties, the stainless steel pipe can play a good anti-corrosion and anti rust effect without using other composite materials. At the same time, stainless steel pipes also have the properties of light weight, pressure resistance, smoothness and beauty, so they are widely used. Non metallic pipes: in addition to some metal pipes introduced above, there are also a large number of non-metallic pipes, such as plastic pipes, rubber pipes, etc. these pipes are usually temporary mobile pipes with the effect of anti-corrosion and rust prevention. The above is the performance introduction of various industrial pipelines. It can be seen that there are great differences in the properties of different industrial pipelines. Industrial pipelines suitable for the working environment need to be selected in different occasions. Now there is an industrial pipe called steel plastic composite pipe, which has excellent performance in all aspects and can adapt to a variety of chemical environments. Our manufacturer focuses on the production of steel plastic composite pipes of various specifications. If you want to buy suitable industrial pipes, you can come to our website to see it and ensure that you will gain a lot.

What are the main factors affecting the strength of steel plastic pipe

Time of issue: : 2022-01--07
The first is that the strength of its substrate is the main influencing factor. We know that the steel plastic pipe is mainly a two-layer structure, one is a plastic structure, and the other is a metal steel structure. Generally, the steel with relatively low purity is barely up to the standard. If you want the strength to be guaranteed by different countries, you can use low-carbon steel or some alloy steel. Therefore, we pay special attention to the selection of informed steel base materials when manufacturing steel plastic pipes. In addition, the plastic material inside the gas is also a factor affecting its structural strength, although it has less impact on the overall structural stability than the outer metal. In the process of composite processing, if the internal pressure is insufficient due to improper process control, it will also lead to the problem of structural instability. Therefore, the manufacturer should properly control the extrusion force of steel plastic pipe to ensure a good composition effect. The above are some factors affecting the structural strength of steel plastic pipe. We can see that in fact, the manufacturing and use of steel plastic pipe are somewhat exquisite. Now the technology has become more and more developed, and all kinds of pipeline materials manufactured by new technology are emerging one after another. Our manufacturer has been committed to the research and manufacturing of steel plastic pipe for many years, and has a very good evaluation in the industry at present. Our steel plastic composite pipe has been widely praised by many people. If you want to feel our steel plastic pipe products in detail, you are welcome to contact us at any time.

Product characteristics of PSP steel plastic pipe

Time of issue: : 2022-01--07
Steel plastic pipe is a very common pipe now. Its structure is roughly a pipe supported by plastic as the base material in the inner layer and steel as the base material in the outer layer. Steel plastic pipe still has a considerable position in the current pipe market, and steel plastic pipe is specially needed in many places. In fact, there are many kinds of steel plastic pipes. People are usually used to classifying according to the plastic materials used inside. For example, PSP steel plastic pipes are made by our manufacturers. PSP steel plastic pipe is made of PSP polystyrene material, which mainly has the following characteristics. (1) PSP steel plastic pipe has very excellent mechanical properties. It can use steel as the main structure and PSP plastic as the inner structure, which complement each other, firm and durable. (2) PSP steel plastic pipe made of dual materials has the characteristics of low thermal conductivity. Because the thermal conductivity of PSP itself is very small, using it as the lining material of steel pipe can greatly reduce heat loss. (3) After specific processing, PSP steel plastic pipe also has the characteristics of low expansion coefficient and can maintain the structural stability in various occasions, which is mainly caused by the creep resistance of steel pipe during composite processing. (4) PSP material with smooth surface can be used to transport fluid well, which is undoubtedly very suitable as a kind of pipeline. Now many PSP steel plastic pipes have also been widely used in some domestic water transmission fields, and have also been well evaluated. (5) PSP steel plastic pipe also has good self tracking performance, that is, we can use magnetic metal detector to detect its position, so as to save a lot of trouble. (6) The PSP steel plastic pipe with composite structure is more portable than ordinary pipe, so it is very convenient for transportation, handling and installation. PSP steel plastic pipe mainly has the above characteristics. In fact, it is not difficult to see that PSP steel plastic pipe has outstanding performance in all aspects of performance, so it has been widely welcomed by people.

Application advantages of precision seamless steel pipe in braking system

Time of issue: : 2022-01--07
There are many pipes used around us. As an advanced pipe product, steel pipe has a very large range of use around us, but these steel pipe products are also very different. Generally speaking, steel pipes are the same. In fact, according to their use or processing technology, these steel pipes can be divided into several categories. Let's take precision seamless steel pipe as an example, Let's introduce the application advantages of precision seamless steel pipe in some braking systems. I hope you can pay attention to its quality requirements when selecting these steel pipe products. Steel pipes are widely used in some pneumatic or hydraulic components. However, in these places, the precision seamless steel pipe used is very different from the steel pipe we usually see. Because in these places, the requirements for steel pipes are relatively high. Some ordinary steel pipes can not meet such requirements at all. Is to make a braking device. Therefore, there are high requirements for the surface finish of the pipeline. In pneumatic or hydraulic devices, after the equipment produces dynamic energy, it needs to transmit these kinetic energy to other components through these braking pipelines. If ordinary steel pipes are used in this place, a lot of energy will be lost in the transmission process. Different from the precision steel pipe, the surface finish of the pipe is different. Let the pipeline not consume too much energy when transmitting energy. In this way, more energy can be transmitted to other parts. This can make the operation of the equipment more smooth, and the use performance can also become more excellent. Because of the manufacturing technology of general steel pipes, the surface of steel pipes is still rough, and even some depressions, protrusions, burrs and so on. It will certainly affect our use. I think some application fields have very high requirements for steel pipes. For example, in braking system or heat exchanger, heat exchanger steel pipes or professional precision steel pipes should be used to meet our use needs. Therefore, when you are free, you should learn more about the use of these steel pipes and use these steel pipe products.

Connection and production mode of steel plastic composite pipe

Time of issue: : 2022-01--07
What is steel plastic composite pipe? I believe we don't need to elaborate more. Steel pipe is still widely used in our life. What is the connection mode of steel plastic composite pipe? What about the main production mode of steel plastic composite pipe? You must be very curious about this. The steel plastic composite pipe manufacturer will introduce the application of steel plastic composite pipe to you. The connection between steel plastic composite pipe and pipe generally includes flange connection, groove connection and screw connection. For the possible leakage problems in the process of screw thread connection, a secondary sealing technology has emerged. In addition to winding the raw material belt around the screw thread for primary sealing, a silicone rubber pad is also placed in the injection molded pipe fitting to form a seal between the end face of the steel plastic composite pipe and the root of the pipe fitting, so as to isolate the metal from water and avoid the slightest contact between the metal part and water. Thus, the problem of connecting anti-corrosion between steel plastic composite pipe and pipe fittings is solved, and the quality of water supply is guaranteed. Steel plastic composite pipe is a kind of economic section steel, which is widely used in crude oil mining and processing, pipeline transportation, machinery manufacturing and large stadium construction. There are many kinds of steel pipes with different product properties. The main production methods are hot rolling, welding and cold processing. Steel plastic composite pipe is a steel pipe with hollow section made of solid pipe blank or steel ingot through perforation and rolling. The steel with high alloy and difficult to deform is produced by extrusion, and the steel plastic composite pipe is mainly produced by extrusion. Steel plastic composite pipe is a process in which the steel plate or steel strip is bent into the required cross-sectional shape by various forming methods, and then the weld is welded by different welding methods to obtain the steel pipe. This paper mainly introduces three connection modes of steel plastic composite pipe and pipe, as well as three processing modes of steel pipe: hot rolling, welding and cold processing.

What is the difference between plastic lined steel pipe and plastic coated steel pipe

Time of issue: : 2022-01--04
Definition of plastic lined steel pipe: plastic lined steel pipe is a steel plastic composite product made of steel pipe as base material, internal and external surface treatment, paint or spray painting, plastic lined polyethylene or other anti-corrosion coatings. Classification of plastic lined steel pipes: plastic lined steel pipes are divided into cold water plastic lined steel pipes, hot water plastic lined steel pipes and rolled plastic lined steel pipes. Plastic lining Plastics: Polyethylene (PE), heat resistant polyethylene (PE-RT), cross-linked polyethylene (PE-X), polypropylene (PP-R), rigid polyvinyl chloride (PVC-U), chlorinated polyvinyl chloride (PVC-C). Plastic lining process: after pretreatment of the steel pipe, glue the outer wall of the plastic pipe evenly, and then put it into the steel pipe to expand it to form steel plastic composite products. Rolling process of plastic lined steel pipe: the steel pipe is heated after pretreatment, and the polyethylene powder is evenly rolled on the inner wall. After the steel pipe rotates, it is cured to form steel plastic composite products. Installation and construction: during the construction and installation process, the plastic lined steel pipe cannot be cut on site due to the change of construction technology. It increases the construction difficulty and cost. The on-site construction of plastic lined steel pipes cannot be prefabricated in advance, and the construction time can be extended. Generally, plastic lined steel pipes will also shrink (relatively speaking), which will increase the design pressure of the pipeline system. Plastic lined steel pipe is relatively wear-resistant due to its thick plastic lining. 2. Plastic coated steel pipe Definition: plastic coated steel pipe is a steel plastic composite product with steel pipe as base material, plastic powder as coating material, internal and external surfaces deposited or anti-corrosion coating of other materials. Classification: according to different coating materials, coated steel pipes are divided into polyethylene coated steel pipes and epoxy resin coated steel pipes. Plastic coating materials: polyethylene powder and epoxy resin powder. Plastic coating process: steel plastic composite products formed after pretreatment, heating, high-speed coating and curing of steel pipes. Installation and construction: the coated steel pipe can be cut at will according to the needs of the construction site, and can continue to be used after cutting and repairing. The plastic coated steel pipe can be prefabricated at the construction site, and the coated steel pipe will not shrink due to the coating. The differences between the two are as follows: (1) Different appearance Plastic coated steel pipe is based on steel pipe and coated with 100% dust made of plastic powder such as polyethylene. The internal and external surfaces of steel pipes shall be evenly coated, and some shall be coated with anti-corrosion coating, and whether to add flame retardant shall be determined according to the degree of use. Although the plastic lined steel pipe is also based on the steel pipe, its appearance is galvanized spraying coating. In the market, it is usually lined with plastic coating or anti-corrosion coating. In the market, the lined PE or PP-R plastic layer is mainly used for drainage and water supply. (2) Different production processes The production process of plastic coated steel pipe is to pretreat and heat the steel pipe first, then quickly coat it and wait for curing. Plastic lined steel pipe includes two processes: lined plastic pipe and rolled plastic pipe. Plastic lining refers to coating adhesive on the outer wall of the plastic pipe and placing it in the heated steel pipe to expand the plastic pipe. Plastic rolling is to heat the steel pipe, heat the plastic dust back to the inner wall of the steel pipe, and wait for it to cool and solidify. (3) Different connection modes The connection modes of plastic coated steel pipes are mainly flange connection, groove connection and thread buckle connection, while the plastic steel pipes are connected to the groove by fattland.
