3pe anti-corrosion steel pipeline is a relatively advanced anti-corrosion technology in recent years. Its full name is fused epoxy/extruded polyethylene structural protective layer. The structure of the 3pe anti-corrosion steel pipeline consists of the following three layers: the bottom layer is fus

Stainless steel flanges are not completely rust-free, but their oxidation resistance is stronger than ordinary steel, so it is called stainless steel.Stainless steel not only can resist atmospheric oxidation but also can corrode in a medium containing acid, alkali, and salt. However, the size of its

resistance, good heat preservation, good impact resistance and long service life1. Hygienic and non-toxic: The material is completely composed of carbon and hydrogen, without adding any toxic heavy metal salt stabilizer. The hygienic performance of the material has been tested by the national author

The most widely used anti-corrosion layers for steel pipelines include petroleum asphalt, PE jacket, and PE foam jacket, epoxy coal tar pitch, coal tar enamel paint, epoxy powder and three-layer composite structure, epoxy coal tar pitch cold wrap (PF type), Rubber-plastic epoxy coal tar pitch cold-w

Stainless steel pipe fittings have high requirements on the quality of the pipe material and have higher requirements on the outer diameter ovality, wall thickness, and physical function of the rubber ring of the drainage cast iron pipe. Due to the poor watertight performance of the flat joint, in a

The use of steel flanges in industrial structural parts is mainly to improve the connection effect and keep the pipeline sealed without leakage. However, many steel flanges will experience corrosion and aging after a period of use, thus losing the sealing effect, so It is very necessary to periodica

(1) There are gravity water pipes and pressure water pipes for water delivery steel pipes. The gravity water conveying steel pipe adopts the self-flow method, the inspection wells are set up according to the requirements, and the spacing is generally 200-400m. In general, intake valves and exhaust v
