Application of black steel pipe


The main purpose of black steel pipes is to transport propane or natural gas to residential and commercial buildings. The pipeline has no joints, making it a better pipeline for carrying gas. Black steel pipe is also used in fire sprinkler systems because it is more fire resistant than galvanized pipe.

Black steel pipes are divided into seamless steel pipes and welded steel pipes. The production process of seamless steel pipe is to pierce a solid tube billet or steel ingot into a hollow capillary tube, and then roll it into a steel tube of the required size. The different piercing and rolling methods used constitute different methods of producing seamless steel pipes.

The production process of welded steel pipe is to bend the tube billet (steel plate or strip steel) into a tube, and then weld the gap to form a steel pipe. Because of the different forming and welding methods used, different methods of producing welded steel pipes are formed.


Seamless steel pipes are mainly produced by hot rolling. The extrusion method is mainly used to produce low-plasticity high-alloy steel pipes or special-shaped steel pipes and composite metal pipes that are difficult to pierce. Cold rolling and cold drawing can continue to process hot rolled pipes into small diameter and thin wall steel pipes. The welding steel pipe process is simple, the production efficiency is high, the cost is low, and the product variety is expanding day by day.
