Electric Resistance Welded (ERW) pipes are a type of welded steel pipe that is produced by continuously forming a flat steel strip into a tubular shape and then welding the edges together using electrical resistance. Various technical standards govern the production and quality requirements of ERW welded pipes. The following are some commonly referenced technical standards for ERW welded pipes.
API 5L: Specification for Line Pipe
The American Petroleum Institute (API) provides standards for the oil and gas industry, and API 5L specifically covers the requirements for line pipe, which includes ERW pipes. It specifies the manufacturing, testing, and dimensional requirements.
ASTM A53: Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless
ASTM A53 is a standard that covers both seamless and welded black and hot-dipped galvanized steel pipes. The standard includes various grades, and it is commonly used for general-purpose applications.
ASTM A135: Standard Specification for Electric-Resistance-Welded Steel Pipe
ASTM A135 specifically covers ERW steel pipes intended for use in fire protection systems, general plumbing, and other similar applications. It provides specifications for various grades of steel.
ASTM A500: Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes
ASTM A500 covers cold-formed welded and seamless carbon steel structural tubing used in construction and structural applications. It includes specifications for round, square, rectangular, and special-shaped tubing.
EN 10219: Cold-formed welded structural hollow sections of non-alloy and fine-grain steels
EN 10219 is a European standard that specifies the technical delivery conditions for cold-formed welded structural hollow sections of circular, square, or rectangular shapes.
DIN 2458: Welded steel pipes and tubes
This German standard specifies the dimensions and technical delivery conditions for welded steel pipes and tubes for various applications.
BS 1387: Steel Tubes and Tubulars Suitable for Screwing to Bs 21 Pipe Threads
BS 1387 is a British standard that specifies requirements for screwed and socketed steel tubes and tubulars for use in water, gas, air, and steam.
GB/T 3091: Welded Steel Pipes for Low Pressure Liquid Delivery
This Chinese standard specifies the technical requirements for welded steel pipes used in low-pressure liquid delivery.
