Carbon steel pipe as a pressure vessel and pipeline core material, its weight size in petrochemical, construction machinery manufacturing and other fields is very big impact, will directly affect the project costing, transportation program design and structural load-bearing safety. This article provides carbon steel pipe weight calculation formula, industry standard comparison and actual engineering cases

The following data is primarily based on the API 5CT standard. For any questions or needs, please contact us via email.

What is ASTM A270？ ASTM A270 is a standard developed by the American Society for Testing and Materials (ASTM). This standard specifies three processes: seamless, welded, and EFW. It is a standard for sanitary-grade piping for austenitic and ferritic stainless steel. It has an extremely high sanitation level and is suitable for processing equipment such

Oil and natural gas are both corrosive, placing extremely high demands on the corrosion resistance of pipelines. The corrosion resistance of a pipeline directly affects its lifespan. So, how can we improve the corrosion resistance of pipelines? External Anti-corrosion Coating External anti-corrosion coating is applied to the outer surface of the pipeline, especially for underwater

All pipes mentioned in this article are sold by our company. What Do The Different Schedules Mean? The number following “Schedule” usually indicates a series of pipe wall thicknesses. The smaller the number after “Schedule,” the thinner the pipe wall, and the larger the number, the thicker the pipe wall. Schedule 40 vs 80 Steel

1. SSAW pipes have high residual stress, while LASW pipes, due to uniform diameter expansion, have very limited residual stress. 2. Because SSAW pipes are formed and welded simultaneously, inspection is impossible. LASW pipes, however, are formed first and then welded, allowing for comprehensive inspection during the process to ensure quality. 3. SSAW pipes have

Carbon steel Carbon steel contains no more than 0.4% to 0.6% copper, no more than 1.6% manganese, and no more than 0.6% silicon, with no other alloying elements added. Carbon steel is categorized as low carbon steel, medium carbon steel, and high carbon steel. For more information about carbon steel, click here. Common grades: GB/T

For steel pipes, the raw material – steel, is the decisive factor in the quality of the pipe. Different types of steel will result in different performance of the pipe. Types Of Steel There are many types of steel. Below I will introduce to you several types of steel commonly used in steel pipes! You

High Strength Of all natural gas pipeline materials, steel gas pipes are the strongest. Steel gas pipes can withstand extremely high internal and external pressures. Long-distance high-voltage transmission lines and high-voltage networks require no other choice but to use steel gas pipes. Good sealing performance: Steel is inherently impermeable. Using the right welding process, a

Connection type Butt weld: End to endSocket weld: Inserted fillet weld Bevel processing Butt weld: The groove must be processedSocket weld: No port processing required Corrosion resistant Butt weld: Excellent corrosion resistance, suitable for harsh corrosive environmentsSocket weld: The corrosion resistance is average, and there may be gaps at the welding end. Surface treatment Butt
