Our steel products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.As the thickness and hardness of increase, the tendency to crack at the cutting edge increases. In order to prevent the from cutting cracks, preheating should be carried out before weather resistant SPA-H steel cutting. Special attention should be paid to preheating to make the entire interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole weather resistant SPA-H steel cannot be preheated, the partial preheating method can be used instead,weather resistant SPA-H steel.In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and steel pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
