Line Pipe

Features

• High strength: able to withstand high internal pressure and external loads.
• Good toughness: has good impact resistance under harsh environmental conditions, such as earthquakes, geological disasters, etc.
• Corrosion resistance: has certain corrosion resistance for the transported fluid, extending the service life of the pipeline.
• Good sealing: ensure that the pipeline will not leak during transportation.
• High dimensional accuracy: convenient for pipeline connection and installation, reducing construction difficulty.

Production process

Line pipe is usually produced by hot rolling or cold drawing. The production process includes tube heating, piercing, rolling, sizing, heat treatment, non-destructive testing, etc. In order to improve the performance of line pipe, special surface treatment may also be carried out, such as anti-corrosion coating, internal coating, etc.

Application field

• Oil and gas transportation: It is the most important transportation pipeline material in the oil and gas industry.
• Chemical industry: used to transport various chemical raw materials and products.
• City gas and water supply and drainage: It is also widely used in city gas and water supply and drainage systems.

Selection considerations

• Material selection: Select the appropriate pipeline material according to the nature, pressure, temperature and other factors of the conveying medium. Common materials include carbon steel, alloy steel, stainless steel, etc.
• Specifications: Select appropriate specifications such as outer diameter, wall thickness, length, etc. according to the requirements of conveying flow, pressure loss, etc.
• Quality standards: Select pipelines that meet national standards or industry standards to ensure reliable quality. At the same time, pay attention to the manufacturer’s quality control system and testing methods.
• Anti-corrosion treatment: For pipelines used in corrosive environments, anti-corrosion treatment should be considered, such as coating, cathodic protection, etc.
• Connection method: According to the construction conditions and requirements, select the appropriate pipeline connection method, such as welding, flange connection, threaded connection, etc.
