petroleum oil well pipes
L80-13Cr is a kind of steel for petroleum oil well pipes. It has good resistance to carbon dioxide corrosion and good resistance to seawater corrosion, making it a common steel for offshore oil and gas production. L80-13cr is a martensitic stainless steel. L80-13Cr martensitic stainless steel pipe is a representative product of oil well pipes used in a wet CO2 environment. It uses the American Petroleum Institute (API) standard product. L80-13Cr has been listed in APISpec5CT ((Casing and Tubing Specifications), because Its excellent CO2 corrosion resistance, relatively high cost, is a very promising corrosion-resistant material for oil fields. Company inventory specifications: 88.9 * 6.45 88.9 * 9.52 177.8 * 10.36 139.7 * 7.72 and can be customized according to requirements, various specifications and sizes, Small quantities can be produced and processed.
L80-13Cr standard requirements: tensile: gt; 655Mpa yield: 552-655Mpa elongation: gt; 15% hardness: 23-24HRC 2Cr13 material composition: C: 0.15-0.22%, Mn: 0.25-1.00%, L8013CR Short joint, Cr: 12.0-14.0%, Ni: lt; 0.25% Quenching 980-1000, tempering 700 is sufficient. Holding time 100 minutes. Cooling method uses nitrogen flush at a certain vacuum and high pressure 2Cr13 quenched and tempered L80-13Cr steel Petroleum tubing. But this material has extremely high hardenability, and oil tubing must be used in accordance with common sense.
