Analysis on Welding Pressure of Gas Power Pressure Welding Casing Subsidies Device
Aiming at the oilfield casing damage,Gas Power Pressure Welding Casing Subsidies Device was designed.The patch principle of the casing patch device was introduced.The metal mooring is an important factor which can affect the welding pressure in the casing subsidies device,so the critical parts of the taper sleeve and metal mooring were analyzed and gained which can expand the force of the different metal mooring punch angle.Then,the optimal punch angle is gained through the stress and strain analysis of metal anchor base on ANSYS.So after applied load,the maximum of the plastic deformation of the metal anchors is gained in order to achieve the best welding casing subsidy results.
