Because oil and gas pipelines are buried underground for a long time, they are very prone to corrosion problems due to soil, moisture and other factors. At present, pipeline corrosion in the petrochemical industry is mainly divided into two types: 1) External corrosion, the so-called external corrosion specifically refers to the corrosion caused by the connection between the metal…
Read MoreAlloy tubes are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. Mainly different from the production standard of alloy pipe and its industry, annealing and tempering of alloy pipe changes its mechanical properties and achieves the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes, and its chemical composition contains more Cr,…
Read MoreASTM A234 standard steel pipe fittings have been widely applied in pipeline systems, it includes carbon and alloy steel material. Grades in ASTM A234: ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on. In these standard Grade WPB is the most common material used for medium and high temperature…

Read MoreStraightening is an important process in the production of LSAW steel pipes. Especially for oil casing and oil and gas pipes of API standard with high quality requirements, special pipes for machinery and equipment.These kinds of steel pipes not only have strict requirements on the steel grade and weld quality, but also have high requirements on the straightness of…
Read MoreThe anti-corrosion coating of seamless steel pipe refers to the use of paint to uniformly and densely coat the surface of the rust-removed steel pipe to isolate it from various corrosive media. It is one of the most basic methods for anti-corrosion of seamless pipes. There are many kinds of anti-corrosion coatings, and their properties and uses are different….
Read MoreStainless steel seamless pipe is a kind of hollow long round steel, which is mainly used for industrial pipelines and mechanical structural parts such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. It is widely used due to its good corrosion resistance. Types of surface defects of stainless steel seamless pipes 1. Rolled…
Read MoreClassification by steel pipe material: Steel pipes can be divided into: carbon steel pipes, alloy steel pipes, stainless steel pipes, etc. Carbon pipes can be divided into ordinary carbon steel pipes and high-quality carbon structural pipes. Alloy tubes can be divided into: low alloy tubes, composite tubes, financial tubes, high-strength tubes, precision alloys (such as Kovar) tubes, and high-temperature…
