Steel-plastic (PSP) composite pressure pipe fittings use PSP special injection fittings, which have the advantages of light weight, low cost, long service life, reliable connection, convenient operation and maintenance, good sealing effect, and can be buried in the dark. The cost of steel-plastic composite pipe fittings is high, the installation and connection are inconvenient, and the sealing effect and corrosion resistance are poor. Steel-plastic composite pipe and double hot-melt pipe fittings and connection technology include: steel-plastic composite pressure pipe and double hot-melt pipe fittings, special equipment related to connection, hot-melt mold, process parameters and other technical contents. The steel-plastic composite pressure pipe is made of galvanized (tin) steel strip bar pressing and argon arc butt welded steel pipe as the middle layer (note: ordinary steel strip for medium and large diameter steel-plastic pressure pipe above DN20O); the inner and outer layers are polyethylene ( Propylene plastics, using special hot melt adhesives, are compounded into one-piece pipes by extrusion molding. The pipeline system formed by connecting steel-plastic pipe and double hot-melt pipe fittings can be widely used in building water supply engineering, petroleum, chemical industry, pharmaceutical, food, Mining, gas and other fields.

product details

H-PSP-PPR (modified) steel-plastic composite pressure pipe is made of argon arc butt welded galvanized steel pipe as the middle layer, and random copolymer polypropylene (PPR) with high temperature resistance, high pressure resistance and low temperature impact resistance as the inner and outer layers , Using imported high-temperature-resistant special hot-melt adhesive, a new type of pipe compounded by synchronous program control is a new type of green pipe that integrates the advantages of steel pipe and plastic pipe.

H-PSP-PPR (modified) welding steps

Step 1: Measure the size of the pipe, mark the pipe, and confirm the socket depth.	Step 2: The pipe and the fitting are socketed.
Step 3: Install the welding jig in the heating area of the socketed pipe and pipe fittings.	Step 4: Turn on the power, press the start button, and enter the welding process. When the fusion splicer emits an audible and visual alarm, the splicing is completed.
Step 5: Remove the welding jig and enter the cooling stage. During the cooling process, the pipes and fittings shall not be rotated and shall be kept in a balanced state

Precautions for storage and transportation of pipes and fittings

1. When the product is transported, it must not be scratched, violently impacted, thrown, and avoid oil and chemical pollution;
2. Pipe fittings should be stored in well-ventilated warehouses or simple sheds, and should not be stored in the open air, away from heat sources;
3. The pipes should be stacked horizontally and neatly, and the stacking height should not exceed 1.5m.
