The difference between structural tubes and fluid tubes
Structural tube: Structural tube is a general structural steel tube, referred to as structural tube. It is suitable for seamless steel tubes for general structures and mechanical structures. The most common material is carbon steel, which can be divided into two types: ordinary carbon structural ...Read more -
Cold drawn seamless steel pipe finish condition
Cold drawn seamless steel pipe finish condition is as follows: Cold finished (hard) BK（+C） Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation Cold finished (Soft) BKW（+LC） The final heat treatment is followed by cold dr...Read more -
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
