Copper-nickel (CUNI or CUPRONICKEL) alloys are used in seawater systems, desalination plants and offshore structure protection
Dec 19, 2023 read moreCharacteristics of submerged arc welded straight seam steel pipe Submerged arc welded straight seam steel pipe body has a longitudinal weld. When the diameter is larger than 914mm, two welds are allowed. Welding wire is used for submerged arc welding. Submerged arc longitudinal weld steel is abbreviated as ASWL, which is a shielded flux weld; The most important feature of submerged arc welded straight seam steel pipe is the use of external welding wire for arc heat melting and the use of submerged arc flux.
Dec 15, 2023 read moreOCTG is the abbreviation of Oil Country Tubular Goods, it mainly refers to the piping products that are applied in oil and gas production (drilling activities). OCTG pipe is normally manufactured based on API or related standard specifications. It could also be taken as a collective name for Drill pipe, Steel Casing Pipe and Tubing pipe, Couplings, Connections, and Accessories, used in petroleum industries both onshore and offshore.
Dec 13, 2023 read moreERW straight seam welded pipe, also known as "resistance welded straight seam welded pipe", ERW straight seam welded pipe is mainly divided into two forms: ERW AC welded steel pipe and ERW DC welded steel pipe. ERW straight seam welded pipes are divided into low frequency welding, medium frequency welding, super medium frequency welding and high frequency welding according to different frequencies. High-frequency welding is mainly used for the production of thin-walled steel pipes or ordinary-walled steel pipes. High-frequency welding is divided into contact welding and induction welding.

Dec 07, 2023 read moreThe internal and external anti-corrosion of SSAW (Spiral Submerged Arc Welded) steel pipes is crucial to ensure their durability and longevity, especially when they are used in environments prone to corrosion. Here are the general steps involved in the internal and external anti-corrosion processes for SSAW steel pipes.
Dec 01, 2023 read moreThe surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to acid, alkaline gas, solution and other media corrosion. It is an alloy steel that is not easy to rust, but it is not absolutely rust free. Stainless steel plate refers to the steel plate that is resistant to the corrosion of weak media such as atmosphere, steam and water, while the acid-resistant steel plate refers to the steel plate that is resistant to the corrosion of chemical etched media such as acid, alkali and salt.
