3PE anti-corrosion steel pipe large diameter 3PE anti-corrosion spiral steel pipe manufacturer

Description :

　　3PE anti-corrosion steel pipe is suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, pumping, 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 engineering, and printing and dyeing. Anti corrosion engineering for sewage treatment discharge pipes, sewage pipes, and biological tanks. For agricultural irrigation pipes, deep well pipes, drainage pipes and other network applications, it can be said that 3PE anti-corrosion steel pipes are essential in current construction, and we believe that with the extension of technology, they will have even more brilliant achievements in the future.

　　How can we distinguish between good and bad? Epoxy resin powder has high adhesion, good cathodic stripping properties, chemical barrier properties, and oxygen resistance. The polymer coating has excellent chemical adhesion with the epoxy resin substrate, which can resist shear forces caused by soil movement and temperature changes. High density polyethylene surface coating has a good barrier effect on moisture, which can protect the epoxy resin bottom layer and polymer coating. It has strong resistance to mechanical damage, reduces peeling, and has low cathodic protection current, suitable for a wide temperature range (-50~80 ℃). After processing, it is firmly combined with the steel pipe to form an excellent anti-corrosion layer. This is just a general statement. After processing, it is firmly combined with the steel pipe to form an excellent anti-corrosion layer. The smallest processing diameter is Φ 104mm (4 '), and the ordinary grade 3PE anti-corrosion steel pipe is introduced. The processing diameter is Φ 1600mm (63'), and the processing capacity is over 350m2/h.

　　It is suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, exhaust gas extraction, fire sprinkler and other pipe networks in coal mines. Thermal power plant process water waste residue, return water transportation pipeline. The applicability of the water supply pipeline of the sprinkler system for anti spray purposes. Its function is really wide coverage. Many people only know one thing about the use of 3PE anti-corrosion steel pipes and do not know the other. It is used for anti-corrosion engineering of power sewage pipes and biological tanks. The main function of the fusion bonded epoxy powder coating for agricultural irrigation pipes is to form a continuous coating film, which is mainly composed of polyolefin rather than polar ethylene. The ethylene part has a good affinity with the surface layer polyethylene. The flexible joint and expansion joint connection will not cause plastic pipe flange breakage, lock head detachment, and other phenomena, and the connection seal is reliable. The problem of weld hardening is also addressed through warm rolling. Improper storage of the pipes after returning to the factory resulted in accelerated formation of "white rust" due to exposure to sunlight and rain outside the workshop. In the short term, the cold rolling market is expected to maintain a slightly weak trend of oscillation at the end and beginning of the month. From the above research results, it can be seen that if users require welded pipes to have good plasticity and do not have high requirements for strength, we can use temperatures between~℃ for continuous annealing. In this case, the temperature range is wide.
