steel tube

Low-temperature seamless pipe is a seamless steel pipe used in low-temperature environment. It has good toughness and strength, will not become brittle due to low temperature, and is widely used in industrial fields that require low-temperature transportation and storage. The production of low-temperature seamless pipe

A honed tube is a steel tube with a precision-processed inner surface, which has a high-precision inner diameter and good surface finish. Its main feature is that the inner surface is processed by a honing process, and is usually used in situations where a high-precision,

High-pressure boiler tubes are mainly used to manufacture superheaters, reheaters, water-cooled walls, economizers, etc. of supercritical or ultra-supercritical boilers. The steel tubes are required to have high endurance strength, high oxidation and corrosion resistance, and good structural stability. Main grades or steel grades: SA-179M, SA-192M,

Precision seamless steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish,

A straight seam steel pipe is a steel pipe with a weld parallel to the longitudinal direction of the steel pipe. It is usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe, etc. The production process of straight

Spiral seam submerged arc welded steel pipe is formed by bending hot-rolled strip steel into a spiral shape, and the inner and outer seams are welded by submerged arc automatic welding to form a spiral seam steel pipe (also called spiral welded pipe, spiral

Seamless steel pipe is an important industrial material and is widely used in petroleum, natural gas, chemical industry, electric power, shipbuilding, bridge building, military industry and other fields. Its unique properties and diverse uses make it an indispensable part of modern engineering. standard The production
