steel pipe

Oil casing pipe is an important equipment used to support the well wall, maintain the stability of the wellbore, protect the drilling mud backflow and prevent the well wall from collapsing during oil drilling. It is a key component of oil extraction and is widely

High-pressure boiler tubes are pipes used in boiler systems to withstand high temperatures and high pressures, and are usually required to have high strength, high temperature resistance and corrosion resistance. The materials of high-pressure boiler tubes usually include the following: Carbon steel: such as 20G

Seamless steel pipes can be divided into the following categories according to different manufacturing processes, materials and uses: 1. Classification by production process Hot-rolled seamless steel pipe: produced by high-temperature rolling, suitable for high strength and high toughness requirements, widely used in machinery, construction, oil

DIN standard (Deutsches Institut für Normung, German Institute for Standardization) is a technical standard system for steel pipes and other materials in Germany. DIN standard is the national standard of Germany and is widely used in the manufacture of various materials and industrial products, including

JIS (Japanese Industrial Standards) provides systematic guidance for the production and application of steel pipes. JIS covers steel pipes made of a variety of materials, including carbon steel, stainless steel, alloy steel, etc. Each material is classified into different steel grades according to its chemical

ASTM (American Society for Testing and Materials) standards are widely used internationally, covering the chemical composition, mechanical properties, manufacturing process and other requirements of various materials. In the field of steel pipes, ASTM standards have specific specifications for different types of steel pipes. The following

Carbon steel material Q355 is a low-alloy high-strength structural steel in the Chinese standard (GB/T 1591-2018), which is widely used in buildings, bridges and other structural engineering. 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.
