Production method and manufacturing requirements of hard chrome plated steel tube

- Jun 11, 2019-

The hard chrome plated steel tube can be effectively divided into seamless steel pipe and seamed steel pipe according to the production method when it is operated, and the seamed steel pipe is simply referred to as straight seam steel pipe.

 

1. Seamless steel pipes can be divided into: hot-rolled seamless pipes, cold-drawn pipes, precision steel pipes, hot-expanded pipes, cold-spinning pipes and extruded pipes according to the production method. The seamless steel pipe is made of high-quality carbon steel or alloy steel, and has hot rolling and cold rolling (drawing) points.

2. Welded steel pipes are divided into furnace welded pipes, electric welding (resistance welded) pipes and automatics due to different welding processes.

The arc welded pipe is divided into a straight welded pipe and a spiral welded pipe because of its different welding forms, and its end shape is further divided into a circular welded pipe and a special-shaped (square, flat, etc.) welded pipe.

 

The hard chrome-plated steel pipe is formed by welding a steel plate rolled into a tubular shape by a seam or a spiral seam. In the manufacturing method, it is further divided into a welded steel pipe for low-pressure fluid transportation, a spiral-welded electric steel pipe, a direct-welded steel pipe, an electric welded pipe, and the like. . Seamless steel pipes can be used in liquid pressure pipes and gas pipes in various industries. Welded pipes can be used for water pipes, gas pipes, heating pipes, electrical pipes, etc.
