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

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

In the manufacture of metal facilities, hot-dip galvanizing and cold-dip galvanizing are two commonly used manufacturing processes. As a metal anti-corrosion method, hot-dip galvanizing usually puts the steel structure to be derusted into the molten zinc at about 500 °C, so that the zinc layer

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

Seamless steel pipe and welded steel pipe are two common types of steel pipes, which have significant differences in manufacturing process, performance, application areas, etc. Seamless steel pipe manufacturing process: Seamless steel pipe is made directly from a whole piece of metal through processes such

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,

Petroleum Oil cracking tubes are seamless tubes for furnace tubes, heat exchanger tubes and pipelines in oil refineries. In the process of oil refining, they are mainly used in cracking units. Cracking is a chemical process that breaks down long-chain hydrocarbon molecules into shorter molecules
