Manufacturing process difference: galvanized steel pipe and seamless steel pipe are two categories of pipe, galvanized steel pipe surface is galvanized, it may be welded pipe, it may be seamless pipe, seamless steel pipe manufacturing process , There are welding and seamless points. Galvanized pipe corrosion-resistant, seamless steel pipe can withstand higher pressures. Galvanized steel pipe due to the protection of zinc, not easy to rust, galvanized steel pipe lighter than seamless steel pipe,...
General seamless steel pipe production process can be divided into cold-drawn seamless steel pipe and hot-rolled seamless steel pipe. The production process of cold-rolled seamless steel pipe is generally more complicated than hot-rolled steel. The pipe blank must be firstly rolled by three rollers. After pressing, the sizing test is performed. If the surface does not respond to cracks, the circular tube is cut by a mower to cut a blank having a length of about one meter. Then enter the...

Galvanized steel pipe is divided into cold galvanized steel pipe, hot-dip galvanized steel pipe, cold galvanized steel pipe has been banned, the latter also advocated for temporary use by the state. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and banned galvanized pipes one after another. China's Ministry of Construction and other four ministries also issued a document stating that the use of galvanized pipes as water supply pipes has been banned...
