The full name of ISO 21809-2 is "Petroleum and natural gas industries - External coatings for buried or merged pipelines used in pipeline transportation systems - Part 2: Single layer", which refers to the external coatings for buried or underwater pipelines used in pipeline transportation systems in the petroleum and natural gas industry - Part 2: Single layer coatings. This standard is mainly applied to pipeline transportation systems in the oil and gas industry, regulating the external coating of buried or underwater pipelines.
Specific regulations of the 2007 version
ISO 21809 - 2: In 2007, the qualification, application, testing, and processing requirements for materials used in single-layer fusion bonded epoxy (FBE) coating factories were specified. This coating is used for external corrosion protection of bare steel pipes in pipeline transportation systems, which belong to the petroleum and natural gas industry category defined in ISO 13623. However, this standard does not cover high-temperature coatings with a glass transition temperature above 120 ° C or FBE primer coatings with three or more layers of polyethylene or polypropylene coatings. Meanwhile, pipelines coated according to this standard are considered suitable for additional protection through cathodic protection.
Position in the field of steel pipe anti-corrosion
In the international standard system for anti-corrosion of steel pipes, ISO 21809-2 is an important component. The commonly used international standards for anti-corrosion technology of steel pipes include ISO 21809-1, ISO 21809-2, ISO 21809-3, and ISO 21809-4, which involve materials, processes, and testing methods for anti-corrosion of steel pipes. Professional steel pipe anti-corrosion manufacturers like Foshan Jingjin Iron and Steel Co., Ltd. strictly produce products in accordance with international standards including ISO 21809-2 to ensure product quality and reliability.
