Alloy seamless steel pipe weather resistant Q355NH steel

What is the difference between weather resistant Q355NH steel, carbon steel pipe and seamless steel pipe? Carbon steel pipe, the performance of this kind of steel pipe is controlled by the amount of carbon content. Different carbon content has different properties and uses. Carbon steel pipe can be seamless or seam welded. Seamless steel pipe is a large category of steel pipe, which can include carbon seamless steel pipe, low alloy seamless steel pipe, high pressure boiler pipe, oil cracking pipe and so on.

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 weather resistant Q355NH 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.
