The steel-plastic composite pipe is made of steel pipe, and the plastic powder is added with modifier, cross-linking agent and binder. The product performance is greatly improved and the stability is enhanced. The products are divided into: steel-lined polyethylene composite pipe (S/PE), steel-lined polypropylene composite pipe (S/PP, PO) and steel-lined PTFE composite pipe (S/PTFE). Straight pipes, elbows, tees, reducers and blind plates.

Performance and characteristics

· Corrosion resistance: The lining plastic layer has strong stability and good anti-corrosion performance for inorganic acid, alkali, salt, gas (H2S, S, CO2, natural gas, gas) alcohol, ketone, aromatic amine and other media.

Anti-aging: chemically functional agents such as modifiers, cross-linking agents and binders are added in proportion to the material of the lining plastic layer, and the low-polarity saturated aliphatic hydrocarbon cross-linking structure inside the lining plastic layer is activated, and the bonding strength is high. Strong resistance to stress cracking and aging.

·Anti-impact and low-temperature resistance: Because the material of the lining plastic layer has low brittleness temperature and flexible molecular chain, it is suitable for long-term use in the working range of -35 ° C - 95 ° C, and has strong impact resistance.

·Resistant to low pressure and high strength: Because the steel-plastic composite pipe adopts steel pipe as the base body, the inner wall of the steel pipe undergoes strict sandblasting, pickling, leaching and steel pipe heating, and the plastic powder is centrifugally compounded, and the steel pipe is added. The bonding strength of the lining plastic layer can withstand a pressure of -0.035 MPa without delamination, bulging and cracking.

Use and cost

Steel-plastic composite pipe has excellent comprehensive performances such as corrosion resistance, aging resistance, impact resistance, low temperature resistance, low pressure resistance and high strength. It is widely used in chemical, petroleum, natural gas, electric power (boiler softened water, desulfurization wastewater system), metallurgy, paper, pharmaceutical, environmental protection and other industries. Gradually replace the cost-effective stainless steel, rubber and other products, reducing the cost of handling and on-site installation, is the ideal anti-corrosion pipeline for users.

Transportation and installation

·When steel-plastic composite pipe is transported, transported and installed, the lining plastic layer of the end face of the pipe is strictly prohibited from scraping, cutting, scratching or colliding with hard objects. If damage occurs, it should be repaired and used.

·The steel-plastic composite pipe is installed by flange or quick joint. It is strictly forbidden to cut and weld the steel-plastic composite pipe body.

· For long-term storage of steel-plastic composite pipes, avoid sun exposure, away from heat and oil, to prevent aging, deformation and pollution.
