The process flow of PE external anti-corrosion steel pipe: raw material inspection → steel pipe preheating and rust removal → rust removal effect inspection → steel pipe medium frequency sensor heating → epoxy powder spraying → polymer adhesive extrusion coating → polyethylene extrusion coating → wa
The characteristics of epoxy powder coating are as follows:① Epoxy powder coating has strong adhesion, especially to metal;② The paint film of epoxy powder coating has good mechanical properties, high hardness, scratch resistance, and corrosion resistance;③ Epoxy powder coatings have low melt viscos
1. Material: The material of the SMSL pipe should meet the requirements of the relevant national standards and industry standards. Common materials include carbon steel, stainless steel, and alloy steel. The selection of material should be based on the working conditions of the pipeline, such as cor
1. Material: Ensure that the welded pipes are made from the appropriate material that suits the specific application requirements. Common materials include carbon steel, stainless steel, and alloy steel.2. Manufacturing Standards: Verify that the welded pipes comply with the relevant manufacturing s
1. Surface Smoothness: The sealing surface of the flange should be smooth to ensure a tight seal between the flange and the gasket. The surface roughness value (Ra) should be within the specified range, typically between 0.4 micrometers and 1.6 micrometers.2. Surface Cleanliness: The sealing surface
Surface defect detection of rectangular tube:Rectangular tube surface defects may include surface scratches, burrs, and oxide scale, etc. The surface defect detection methods for rectangular tube usually include visual inspection, touch inspection, eddy current inspection, X-ray inspection, and othe
To protect carbon steel pipes from rust and corrosion, the following steps can be taken:1. Surface Preparation: The surface of the carbon steel pipes should be cleaned thoroughly to remove dirt, grease, and rust. This can be done by using a wire brush, sandpaper, or abrasive blasting.2. Primer Appli
General welded pipe: General welded pipe is used to transport low-pressure fluid. Made of Q195, Q215A, Q235A steel, and Q235B plain carbon. It can also be made of easy-to-weld 0317 standard model 6012 and steel mother 755 mild steel. Steel pipes are subject to hydraulic pressure, bending, flattening
Most merchants did not use the straight seam steel pipe soon after purchasing it. So is there anything we need to pay attention to in the storage of straight seam steel pipes? The staff of the straight seam steel pipe manufacturer reminded us that the correct storage method of the straight seam stee
