Packaging requirements for seamless tubes
The packaging requirements of seamless tubes (smls) are basically divided into two categories: one is ordinary bundling, and the other is loading in similar containers with turnover boxes. 1. Bundled packaging (1) Seamless tubes should be prevented from being damaged during bundling and transport...Read more -
Packaging method of anti-corrosion spiral steel pipe
Packaging method of anti-corrosion spiral pipe: 1. Our country stipulates that the anti-corrosion spiral steel pipe adopts the method of bulk weighing. The size of the baler should be in the middle of 159MM to 500MM as far as possible. The raw material of the baler uses steel belts, each of which...Read more -
Steel Tube Weld Cold Crack
Cold crack reasons: the person to be subjected to welding when a large tensile force can be easily torn in the process of cooling the welding material hardenability; welding cooling rate was too late to escape the residual hydrogen in the weld, a hydrogen atom bonded to a hydrogen molecules to a ...Read more -
How to check the quality of galvanized seamless steel pipe?
There are two types of galvanized seamless steel pipes, hot-dip galvanizing (hot-dip galvanizing) and cold-dip galvanizing (electro-galvanizing). Hot-dip galvanizing has a thick galvanized layer, which has the advantages of uniform coating, strong adhesion, and long service life. However, the cos...Read more -
What are the application fields of welded steel pipe?
Welded steel pipes are widely used in the structural parts of bicycles, motorcycles, tractors, automobiles and large buses. The pipe has a large forging coefficient, strong bending and torsion resistance, smooth surface and light weight. Variable cross-section tubes are used to make collector pol...Read more -
Treatment method for damage of parts of cold drawn welded pipe
The maintenance of cold drawn welded pipe requires regular maintenance according to the corresponding maintenance standards. Even if the working condition is good, it is necessary to carry out all-round maintenance on the welded pipe unit to fundamentally avoid mechanical failure and ensure smoot...Read more
