The internationally used oil and gas pipeline construction standards are mainly the following:

API Standard

API 5L: Published by the American Petroleum Institute, it specifies the manufacturing requirements and pipeline line pipe specifications for steel pipelines used to transport natural gas, oil and water, and makes detailed provisions for the steel grade, size, wall thickness, material, etc. of steel pipes.

API 1104: Covers the requirements for welded steel pipes, including welding processes and acceptance standards in pipeline projects, and puts forward specific specifications for welding materials, welding process assessment, weld quality inspection, etc.

ASME Standard

ASME B31.4: For liquid transportation pipelines, it stipulates the design, material selection, construction, inspection and testing of pipeline systems, and requires the selection of appropriate pipes and pipe diameters based on the properties, flow rate, pressure and other factors of the transported liquid.

ASME B31.8: Mainly used for natural gas pipelines, it has clear requirements for the design pressure, temperature range, pipe performance, etc. of the pipeline, and stipulates that the pipeline must be able to withstand the expected internal pressure, external pressure and temperature changes.

ISO Standards

ISO 13623: covers the requirements for the design, construction, operation and maintenance of pipeline systems in the oil and gas transportation industries, and provides guidance on the material selection, strength calculation, anti-corrosion measures, construction technology and other aspects of pipelines.

ISO 16440: specifies the design, manufacture, installation and maintenance requirements of steel casing pipelines in the oil and gas industry, including casing design, electrical isolation, corrosion protection and other aspects.

ISO 15156: The standard for the selection, welding and heat treatment of materials for oil and gas production equipment used in sulfur-containing media is of great guiding significance for the construction of oil and gas pipelines in sulfur-containing environments.

ISO 13847:2000: is the "Petroleum and Natural Gas Industry-Pipeline Transportation System-Pipeline Welding" standard formulated by the International Organization for Standardization, which specifies the requirements and specifications for welding of oil and gas pipelines, covering the scope of application, term definition, welding materials, welding methods, welding process assessment, welding quality inspection and special situation handling.

ISO 21809: ISO 21809-2 specifies the requirements for external coatings of buried or submerged pipes used in pipeline transportation systems in the oil and gas industry, such as fusion-bonded epoxy coatings.

Other standards

CSA Z662: Published by the Canadian Standards Association, it is the pipeline system standard in the field of Canadian natural gas and oil industry, including design, construction, operation and maintenance.

EN 10208: Published by the European Committee for Standardization, it is the manufacturing standard for steel pipes used for gas pipelines in Europe, and specifies the size, shape, weight, technical requirements, etc. of steel pipes.

EN 14570:2014: Published by the European Committee for Standardization, it is a standard for above-ground and underground liquefied petroleum gas (LPG) pipeline equipment in liquefied petroleum gas (LPG) equipment and accessories.

EN ISO 12736:2014: Specifies the requirements for wet insulation coatings for pipelines, pipelines, equipment and underwater structures in the oil and gas industry.

EN ISO 20074:2019: Covers geohazard risk management for oil and gas pipelines in the oil and gas industry.

DNV-OS-F101: A standard published by Det Norske Veritas (DNV) titled Subsea Pipeline Systems, applicable to subsea and onshore pipeline systems, including natural gas transmission.
