1. Impact toughness of large-diameter steel pipe: The load acting on the machine part at a high speed is called impact load, and the ability of the metal to resist damage under the action of impact load is called impact toughness.2. Strength of large-diameter steel pipe: Strength refers to the perfo

Thick-walled steel pipes have a wide variety of steel types and specifications, and their performance requirements are also various. All of these should be differentiated as user requirements or working conditions change. Generally, steel pipe products are classified according to cross-sectional sha

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

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
