steel pipe

Seamless steel pipe is a steel pipe made by perforating steel billets and is widely used in various industrial fields. Carbon steel: Commonly used ones are ASTM A53, A106, API 5L, A335, etc. ASTM A53: Seamless and welded steel pipes for general use and mechanical

Galvanized steel pipe refers to a steel pipe with a layer of zinc on the surface to achieve the effect of corrosion and rust prevention. Galvanized steel pipe is widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, railway vehicles, automobile

Straight seam welded pipe (LSAW) and spiral welded pipe (SSAW) are two common types of welded steel pipes, which are widely used in oil and gas transportation, construction, infrastructure and other fields. Straight seam welded pipe (LSAW) Production process 1. Raw materials: steel plate or

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

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

API 5L generally refers to the implementation standard of pipeline steel pipes. Pipeline steel pipes are used to transport oil, gas, water, etc. extracted from the ground to oil and gas industrial enterprises. Pipeline steel pipes include seamless steel pipes and welded steel pipes. At

The main purpose of galvanizing steel pipes is to improve their corrosion resistance. Galvanizing is a process that covers the surface of steel pipes with a layer of zinc. This zinc coating can provide good protection for the steel pipes. The following are the main
