Regarding the calculation method of carbon steel pipe weight, many people do not know the theoretical weight calculation formula of carbon steel pipe Calculation formula for steel pipe weight: (outer diameter – wall thickness) × Wall thickness mm × zero point zero two four six six × Length m Example: steel pipe 114mm (outer diameter) […]

The site or warehouse for steel storage should be selected in a clean and well-drained place, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed on the site to keep the steel clean; In the warehouse, it is not allowed to be piled together with materials

At present, there are mainly 304, 201 and 301 materials on the market. If the content of chromium and nickel is different, there will be differences. Material 304 contains chromium 18 and nickel 8-9, while materials 201 and 301 only contain chromium 14 and 16 and nickel 1 and 5 respectively. It has been scientifically

API 5L generally refers to the implementation standard of pipeline steel pipes. Pipeline steel pipes are used to transport oil, steam, water, etc. extracted from the ground to oil and gas industry enterprises. Pipeline steel pipes include seamless steel pipes and welded steel pipes. At present, the welded steel pipes commonly used in oil pipelines

Formula 1: (outer diameter – wall thickness) * wall thickness * 0.02466 = kg meter (weight per meter) Formula 2: (outer diameter – wall thickness) * (0.02466+0.00172) = kg meter (weight per meter) Seamless steel pipe weight calculation formula: (outer diameter – wall thickness) * wall thickness * 0.000823 = kgm3 Weight calculation: The allowable

API5L generally refers to the implementation standard of pipeline steel pipes, which are used to transport oil, steam and water pumped out of the groundPipelines that are transported to oil and gas industry companies. Pipeline steel pipes include seamless steel pipes and welded steel pipes.At present, the welded steel pipes commonly used on oil pipelines

Electrofusion welded pipes can be subjected to water pressure, flaw detection, X-ray reports, and material protection Classification of steel pipes for electric power: Steel pipes are divided into two categories: seamless steel pipes and welded steel pipes (welded pipes). According to the shape of the cross-section, it can be divided into circular pipes and special-shaped

GB/T8162-2018, structural seamless steel pipes, mainly used in general structural engineering, machining, construction and other fields. Representative materials: 20#, 45#, q345b, 40Cr, 42CrMo, etc.; GB/T8163-2018, seamless steel pipe for fluid transportation, mainly used for pipeline engineering with low pressure. Representative material: 20#, q345b; 45# GB8162 structural seamless steel pipe GB/T3087-2017, low and medium pressure boiler

Welding rod arc welding of pipeline: welding rod arc welding of pipeline is the most commonly used welding method in general factories at present. It is a method of manually melting pipe wall and welding rod, mixing to form molten pool and solidification to form weld. The electrode arc welding equipment is simple, flexible and
