The design of L360 pipeline needs to meet the following principles:
1. Strength requirements: L360 pipeline needs to have sufficient strength to withstand external forces and pressures to ensure the safe operation of the pipeline.
2. Corrosion resistance: Since pipelines often transport corrosive substances, the corrosion resistance of the material should be considered in the design, and the appropriate material should be selected to extend the service life of the pipeline.
3. Sealing: The design of pipelines should ensure good sealing performance to prevent leakage and oil spills.
4. Transportation and installation requirements: Considering that pipelines need to be transported and installed, the design should take into account easy handling, connection and installation.
Material selection: L360 pipelines usually use X52N or L360N steel grades, and the smelting and product analysis of these steel grades meet the requirements of API Spec 5L-2007. Seamless steel pipes are rolled from continuous casting billets, and the quality of continuous casting billets should meet the requirements of YB/T4149-2006 standards.
Specifications and standards: The specification range of L360 pipeline pipe is 27-720mm*3-50mm, and the applicable standard and grade is API Spec 5L-2013 PSL1. In addition, L360 pipeline pipe also implements GB/T9711-2017 (national standard) implementation standard.
Production process: The production process of L360 pipeline pipe includes continuous casting billet inspection, cutting, heating, perforation, pipe rolling, sizing, intermediate geometric dimension inspection, cooling, straightening, sizing, blowing and suction, magnetic leakage detection, manual inspection, water pressure, spraying and warehousing. Application scenario: L360 pipeline pipe is mainly used for gas, water and oil transportation in the petroleum and natural gas industry, and is suitable for fluid transportation in various pipeline systems.
