Oil pipeline pipe is a key equipment used for long-distance transportation of crude oil, natural gas, and refined oil products, and is an important "energy channel" connecting oil and gas resources with the market. It is usually made of high-strength steel such as X42, X52, X60, X65, X70, X80, etc. It has the characteristics of high pressure resistance, good toughness, strong weldability, and outstanding corrosion resistance, and can adapt to complex working conditions such as high pressure, low temperature, and strong corrosion. Its specification range is wide, ranging from Φ 114mm to Φ 1420mm. The production process includes spiral submerged arc welding, straight seam submerged arc welding, high-frequency welding, etc. It complies with international and national standards such as API 5L, ISO 3183, GB/T 9711, etc. Oil pipeline pipes are widely used in land long-distance pipelines, ocean pipelines, shale gas transmission projects, and urban gas pipelines, and are important basic materials for ensuring national energy security and stable oil and gas supply.
