Thin-wall stainless steel pipe socket argon arc welding construction method has the following characteristics:1. The welding process does not require welding consumables (replaced by the expanded pipe edge). The steel pipe is inserted into the pipe fitting socket. The socket end is welded in a circl
Spiral steel pipe requires surface treatment to increase durability:1. Use solvents and emulsions to clean the surface of the anti-corrosion spiral tube, which can remove the organic matter on the surface of the spiral tube, but it cannot remove the surface rust, scale, welding flux, etc., so cleani

When the product arrived at the energy transportation project location, it
1. Wrong side.This is a common problem in pre-welding, and the wrong side is out of tolerance, which directly leads to the degradation or scrapping of the steel pipe. Therefore, it is required to strictly control the misalignment amount during pre-welding. When the whole or more than half of the ste
1. Broken pipe: draw a line on the selected pipe according to the on-site surveying and mapping sketch, and cut the pipe according to the line.a. To cut the pipe with a grinding wheel saw, put the pipe on the caliper of the grinding wheel saw, align it with the drawn line and clamp it firmly, and th
Precautions for storing straight seam steel pipes:Most merchants did not use them soon after purchasing straight seam steel pipes. So do we need to pay attention to the storage of straight seam steel pipes? The staff of straight seam steel pipe manufacturers is reminded that how to store straight se

Large-diameter steel pipes are widely used in mechanical parts, fluid transportation, construction sites, etc. Large-diameter steel pipes have undergone strict inspections during manufacturing, which has also improved their durability. Large-diameter steel pipes have high dimensional accuracy and sm
1. The use of large-diameter stainless steel pipe can be divided into oil well pipes (casing pipes, oil pipes and drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure chemical fertilize
Steel pipe anti-corrosion methods generally use coating anti-corrosion. Coating anti-corrosion is to apply coating uniformly and densely on the surface of the rusted metal pipe to isolate it from various corrosive media.1. Anti-corrosion coating on the outer wall of steel pipeThe anti-corrosion of t
