Welded steel pipes are critical in a wide range of industries, serving various purposes from fluid transportation to structural applications. To ensure the quality and suitability of these pipes for different uses, several standards have been established. Here are some of the key standards governing welded steel pipes.
GB/T9711.1: Specifies the technical requirements for the delivery of steel tubes in the oil and gas industry, focusing on part 1.
GB/T9711.2: Outlines the technical conditions for delivering steel pipes in the oil and gas industry, detailing part 2.
GB/T9711.3: Covers the technical conditions for the delivery of steel pipes in the oil and gas sector, specifying part 3.
GB/T3092: Defines the standards for welded steel pipes used in low-pressure fluid transportation.
GB/T3091: Provides the standards for galvanized welded steel pipes designed for low-pressure fluid transportation.
GB3640: Sets the standards for ordinary carbon steel wire casing.
GB/T12770: Details the standards for stainless steel welded pipes intended for mechanical structures.
GB/T12771: Specifies the standards for stainless steel welded pipes used for fluid transportation.
GB/T14291: Establishes the standards for welded steel pipes used in mining fluid conveying.
YB242: Describes the standards for straight seam electric welded steel pipes.
SY5036: Lays out the standards for spiral submerged arc welded steel pipes intended for pressurized fluid transportation.
SY5038: Covers the standards for spiral seam high-frequency welded steel pipes used in pressurized fluid transportation.
SY5037: Provides the standards for general spiral submerged arc welded steel pipes for low-pressure fluid transportation.
SY5040: Defines the standards for pile spiral welded steel pipes.
These standards ensure that welded pipes meet specific requirements for strength, durability, and performance across various applications, from oil and gas pipelines to construction and mining operations. They provide comprehensive guidelines that manufacturers must follow to ensure their products are reliable and fit for purpose.
