Oil casing pipe   is used to support the walls of oil and gas wells to ensure the operation of the entire oil well after the drilling process. So what technical specifications does it have? 1. The domestic bushing pipe shall be in accordance with the regulations of SY/T6194-96, and the length of the bushing pipe is not fixed, and its can be 8-13m. And casing pipe that not shorter than 6m can be provided, and its quantity shall not exceed 20%. 2. The inner and outer surfaces of the casing pipe shall be free from folds, hairlines, delaminations, cracks, folds and scabs. These defects shall be completely removed, and the removal depth shall not exceed 12.5% of the nominal wall thickness. 3. The outer surface of the coupling must not have defects such as folds, hairlines, separation layers, cracks, rolling folds, and scarring. 4. The thread of the casing pipe and coupling should be smooth, without burrs, tears and other defects that can interrupt the thread and affect the strength and tigh

A335P91 alloy tube  boiler is a high temperature and high pressure equipment used to generate high temperature steam for use in power plants and other industries. The production of A335P91 alloy tube boilers is a complex process that requires strict production and testing standards. The following is an introduction to the production process of A335P91 alloy tube boilers. 1. Raw materials The main components of A335P91 alloy tube boiler are chromium, molybdenum, iron, carbon and other elements, and the raw material is also alloy steel with good high temperature resistance and corrosion resistance. We take 12Cr1MoV steel produced by Baosteel as the raw material for the A335P91 alloy tube boiler. 2. Processing The processing of A335P91 alloy tube boiler requires the use of advanced production technology and equipment to ensure the quality of the product. In the processing, it needs to do multiple process links such as rough machining, heat treatment, finishing, heat treatment, etc., to en

1: Knowing the outer diameter, specification and wall thickness of the   seamless bright tube , how to calculate the withstand pressure (the tensile strength of different materials of the steel tube is different) Pressure = (wall thickness * 2 * tensile strength of steel pipe material) / (outer diameter * coefficient) 2: The outer diameter of the seamless steel pipe and the bearing pressure are known, how to calculate the wall thickness of pipe: Wall thickness = (pressure * outer diameter * coefficient) / (2 * tensile strength of steel pipe material) 3: The expression method of the pressure coefficient of the seamless bright tube: Pressure P<7Mpa   Coefficient S=8 7< steel pipe pressure P<17.5   Coefficient S=6 Pressure P>17.5   Coefficient S=4 Changsha Xiangjia Metal Materical Co., Ltd.  as steel division of  ADTO Group , we have over 20 years of piping materials making experience and insight into Oil & Gas, Water, Mining, Marine and infrastructure and specializing in
