TPEP anti-corrosive steel pipe


The outer wall of TPEP anti-corrosive steel pipe adopts 3PE hot-melt winding process. (bottom epoxy, middle layer adhesive, outer layer polyethylene) an anti-corrosive layer or a single-layer polyethylene (PE) with a three-layer structure is formed, the inner wall adopts a thermal spraying epoxy powder anti-corrosive mode, the powder is uniformly coated on the surface of the pipe body after high-temperature heating and melting, the adhesive force of the coating and the thickness of the coating are improved, and the bump resistance is enhanced. corrosion resistance, simple construction, coating and solidifying inside and outside of the pipeline simultaneously, one-time film formation, which widely applicable to pipeline corrosion in various anti-corrosion engineering fields. TPEP anti-corrosion seamless steel pipe advantages:

1、 TPEP steel pipe price is more expensive but the roughness rate is low, and the diameter of TPEP steel pipe required is smaller than that of ductile iron pipe at the same flow rate. For example, the diameter of the ductile cast iron pipe in this project is DN 1200mm, TPEP steel pipe only DN 1000mm on the line, so to apply TPEP steel pipe which save more than ductile iron pipe.

2、 TPEP steel pipe is different from common steel pipe, it has been made internal and external anti-corrosion, which no harm for drinking water.

3、 TPEP steel pipe has stronger resistance to water hammer than ductile iron pipe.

4、 The requirements for the foundation of the two types of pipes are basically the same.

5、 In the construction, TPEP steel pipe is welded, with higher technical requirements and slower construction progress. Ductile iron pipe is splicing, the technical requirements are general, the construction progress is faster, but more buttresses are needed.

6、 Under the same working conditions, the diameter of TPEP pipe is reduced more than that of ductile iron pipe by one size, and the excavation amount of earthwork, temporary land occupation, size of pipe fittings, and the occlusion of the corresponding pipeline are reduced correspondingly.
