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

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
