ISO3183 L290ME line pipe with 3LPE coated<\/p><\/div>\n

ISO3183 Annex A L290ME Line Pipe with 3LPE Anti-Corrosion Coating<\/h1>\n
This pipe system (ISO3183 L290ME line pipe + 3LPE anti-corrosion coating) is specifically designed for the\u00a0safe, efficient, and long-term transportation of methane<\/strong>. Its core function is to serve as a “transportation carrier” for methane (the main component of natural gas, typically accounting for \u226595% by volume) from extraction sites and processing plants to end-users. Meanwhile, through its material properties and anti-corrosion structure, it addresses key challenges in methane transportation such as pressure resistance, leak prevention, and environmental corrosion resistance, making it suitable for medium-to-high pressure, long-distance, and multi-environment transportation conditions.<\/div>\n

1.Manufacturing:<\/b><\/p>\n

If agreed, the manufacturing procedure shall be qualified in accordance with API Spec 5L, 46th edition (2018), Annex B.<\/p>\n

2.Steel making\u00a0<\/span><\/b><\/span><\/p>\n

The steel shall be made to a clean steel practice, using either the basic oxygen steel-making process or the electric-arc furnace steel-making process, and shall be fully killed and be made according to fine grain practice.\u00a0<\/span><\/p>\n

3.Pipe manufacturing<\/b><\/p>\n

3-1 Unless otherwise agreed, coil and plate used for the manufacture of welded pipe shall be rolled from continuously (strand) cast or pressure cast slabs. The pipe shall be HFW in the M delivery conditions only as described in API Spec 5L, 46th edition (2018), Table 3.\u00a0<\/span><\/p>\n

3-2 For HFW pipe from hot-rolled coil, the pipe forming process ‘cold forming followed by thermomechanical forming’ as described in API Spec 5L, 46th edition (2018), Table 3, shall not be used.\u00a0<\/span><\/p>\n

3-3 For HFW pipe, the abutting edges of the coil or plate shall be sheared, milled or machined before welding such that the edges are clean and free of damage.<\/p>\n
