Q355 belongs to low-alloy high-strength structural steel. According to Chinese standards, it is a typical low-alloy steel suitable
API Standard is an industry standard developed by the American Petroleum Institute (API) and is widely used in the oil and gas industry. API Standard covers all aspects from exploration, production, processing to transportation and sales, ensuring the safety, reliability and compatibility of equipment and
The purpose of anti-corrosion treatment of steel pipes is to extend their service life, protect them from environmental factors, and avoid economic losses and safety hazards caused by corrosion. The specific reasons include the following: Extend life: Anti-corrosion treatment can significantly extend the service life
There are many anti-corrosion processing technologies for steel pipes. The following are some common anti-corrosion treatment methods: Coating anti-corrosion: Epoxy resin coating: Epoxy resin has good adhesion and corrosion resistance, and is often used for internal and external corrosion protection of oil and gas pipelines.
A natural gas pipeline is a specially designed pipeline system for transporting natural gas. The materials of natural gas pipelines mainly include the following: Carbon steel: the most commonly used material, due to its high strength, good corrosion resistance and low cost. Alloy steel: used
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
