TPEP anti-corrosion pipeline epoxy powder anti-corrosion steel pipe TPEP anti-corrosion spiral steel pipe manufacturer

Description :

　　The full name of TPEP anti-corrosion steel pipe is: externally wrapped polyethylene and internally fused epoxy anti-corrosion pipeline. External wrapping of polyethylene refers to the 3PE anti-corrosion treatment of the outer wall of the pipeline, consisting of three layers: one layer of epoxy powder, one layer of adhesive, and the last layer of polyethylene wrapping. Internal fusion bonding epoxy refers to the anti-corrosion treatment of epoxy resin powder on the inner wall of the pipeline, which refers to the use of high-temperature fusion bonding production technology to coat the pipeline with epoxy resin powder. The product solves the adhesion problem of single-layer polyethylene on steel pipes. At the same time, the anti-corrosion standard of the inner wall has reached food grade.

　　TPEP anti-corrosion steel pipes have undergone four upgrades and replacements in China. As early as the 1980s, it was introduced from Japan with a one-time vulcanization bed impregnation film-forming process, using modified polyethylene for anti-corrosion. Due to the adhesion problem between polyethylene and steel pipes, it gradually developed to be coated with epoxy resin powder inside and outside. However, the outer wall epoxy resin coating is brittle and not resistant to bumps. Later, it developed into the third generation of inner wall epoxy outer wall polyethylene anti-corrosion, but there are still adhesion problems when single-layer polyethylene is directly combined with steel pipes, and bumps are inevitable during construction. It was later upgraded to the current fourth generation anti-corrosion - external 3PE anti-corrosion and internal fusion bonded epoxy powder anti-corrosion. The 3PE anti-corrosion layer is formed by synchronously winding or extruding fusion bonded epoxy powder (FBE) as the bottom layer, adhesive as the middle layer, and extruded polyethylene as the outer protective layer, which has excellent insulation performance and mechanical damage resistance, and has advantages over single-layer polyethylene anti-corrosion.

　　TPEP spiral steel pipe is an upgraded product based on the outer single-layer polyethylene and inner epoxy composite steel pipe, and is currently an advanced form of steel pipe anti-corrosion for buried long-distance pipelines. TPEP steel pipes have filled the gap in domestic steel pipes The anti-corrosion blank has increased its corrosion resistance by 3-5 times.

　　The anti-corrosion steel pipe has a wide coverage and is suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks in coal mines. Thermal power plant process water waste residue and return water transportation pipeline. The applicability of water supply pipelines for anti spray and sprinkler systems. Cable protection sleeves for power, communication, highways, etc. Suitable for high-rise building water supply, heating network, water supply engineering, gas transmission, buried water transmission and other pipelines. Process pipelines for transporting corrosive media in industries such as petroleum transportation pipelines, chemical pharmaceuticals, and printing and dyeing. Anti corrosion engineering for sewage treatment discharge pipes, sewage pipes, and biological tanks. It can be said that 3PE anti-corrosion steel pipes are essential in current construction for agricultural irrigation pipes, deep well pipes, drainage pipes and other network applications.

　　Coating anti-corrosion is one of the basic methods for steel pipe anti-corrosion, which involves uniformly and densely coating the surface of rust removed metal pipes with coatings to isolate them from various corrosive media. The anti-corrosion coating of steel pipes is increasingly using composite materials or composite structures. These materials and structures should have good dielectric properties, physical properties, stable chemical properties, and a wide temperature adaptability range.

　　TPEP anti-corrosion steel pipe products are used in coal mines, suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation and gas drainage, fire sprinkler, etc. It can also be used as a water waste and return water transportation pipeline for thermal and electric processes in power plants, and can also be used as a water supply pipeline for fire protection and sprinkler systems in the firefighting industry. Anti corrosion steel pipes have different uses in various industries such as power, communication, and highway cable protection sleeves on highways, and the development of anti-corrosion steel pipes is becoming increasingly applicable and rationalized.
