Submerged arc welding (SAW) is one of the most efficient mechanized welding methods today. Its full name is automatic submerged arc welding, also known as automatic arc welding under the flux layer. Submerged arc welding technology is ideal for important applications such as pipelines, pressure vessels and storage tanks, rail manufacturing and large-scale construction. Available in the simplest form…
Read MoreStructural seamless pipe (GB/T8162-2008) is a kind of seamless steel pipe used for general structure and mechanical structure. The fluid seamless steel pipe standard applies to seamless steel pipes that transport fluids. In addition to carbon (C) elements and a certain amount of silicon (Si) (generally no more than 0.40%) and manganese (Mn) (generally no more than 0.80%, higher…
Read More1. Use of seamless steel pipes for structures: seamless steel pipes for such structures are now more suitable for general structures and their mechanical equipment structures. Compared with others, the quality of such seamless steel pipes is There are some practical differences. 2. Use of seamless steel pipe for fluid transportation: This type of seamless steel pipe is widely…
Read MoreIn the production process of spiral steel pipe, if the production process is unreasonable and the machine parameters are not properly set, there will be deviations, especially for large-diameter spiral steel pipes, which is often referred to as the wrong side phenomenon. During the production of spiral steel pipe, the wrong side occurs from time to time, and there…
Read MoreBecause 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 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….
