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

ASTM A333 is a standard developed by the American Society for Testing and Materials. The full name of ASTM A333 is: ASTM A333/A333M – Standard Specification for Seamless and Welded Steel Pipe for Low-Temperature Service and Other Applications with Required Notch Toughness. In summary, A333 is specially developed for low-temperature applications. ASTM A333 Standard A333

OCTG Pipe – OCTG Meaning OCTG stands for Oil Country Tubular Goods. OCTG Pipe is the lifeline of the oil industry, ensuring the safety and efficiency of the oil extraction and transportation industry. OCTG Pipe – Three Types Drill pipe Drill pipe, consisting of a caliper, drill bit, drill rod, and casing, is primarily used

What is the full name of the ASTM A312 standard? It stands for “Standard Specification for Seamless, Welded, and Severely Cold-Worked Austenitic Stainless Steel Pipe.” A312 pipe is a standard specifically for austenitic stainless steel pipe. While its corrosion resistance is average, it is resistant to high temperatures and is widely used in industries such

SCH pipe is a pipe wall thickness grade standard commonly seen in the piping industry and established by the American National Standards Institute (ANSI). SCH10 is considered a relatively thin grade in this standard.This article will explain Schedule 10 pipe dimensions and other related knowledge Schedule 10 Pipe Dimensions Schedule 10 Pipe Dimensions – Advantages Schedule
