Large diameter coated steel pipe
Coated steel pipe is manufactured by coating plastic based on large-diameter spiral welded pipe and high-frequency welded pipe. The maximum pipe diameter is 1200mm. Polyvinyl chloride (PVC), polyethylene (PE), epoxy can be coated depending on different needs. Resin (EPOZY) and other plastic coati...Read more -
Precautions for Purchasing Large Diameter Straight Seam
Before purchasing large-diameter straight seam steel pipes (LSAW), you should follow the pre-designed specifications, lengths, materials, wall thicknesses, welding standards and weld requirements, which must be communicated well before purchasing. 1. The first is the specification. For example, 8...Read more -
Three ways to ensure smoothness as required when producing straight seam steel pipes
1. Rolling mold: The general method of rolling mold is to press the glass powder into a glass mat. Before the straight seam steel pipe is rolled, the glass mat is clamped between the steel and the center of the rolling mold, to make the glass pad in the center. Under the effect of conflict, the s...Read more -
10 Ways to remove burrs from seamless steel tubes
Burs are ubiquitous in the metalworking process. No matter how advanced and sophisticated equipment you use, it will be born with the product. This is mainly due to the plastic deformation of the material and the generation of excessive iron filings at the edges of the processed material, especia...Read more -

Representation methods and welding methods of welded
How to indicate the grade of welding steel: Welding steel includes carbon steel for welding, alloy steel for welding, stainless steel for welding, etc. The way to indicate the grade is to add the symbol “H” to the head of each type of welding steel grade. For example H08, H08Mn2Si, H1Cr18Ni9. For...Read more -
How to deal with different wall thicknesses of boiler steel
When the thickness of the boiler steel pipe wall is different, compensation gaskets can be used to deal with it. 1. The thickness of the steel pipe wall can be thickened or thinned to achieve the required thickness. 2. When the steel pipe wall thickness is inconsistent, high-strength bolts and wa...Read more -
