Jiaxing bearing sharing: stainless steel pipe production technology

There is rotational, have HRB bearing ( ) Jiaxing bearing sharing: stainless steel pipe production technology. Jiaxing bearing group sales co. , LTD. ( The company) Is in jiaxing bearing group set up by the spot sales window, specializing in HRB brand bearings, existing stocks of 50 million yuan, covers the whole bearing, have very strong cash supply ability. With the improvement of constant demand for stainless steel tube, so in view of the stainless steel pipe production technology is also in constant improvement, the following for more accord with our use stainless steel tube, today to introduce the three common processing production of stainless steel tube technology. Drawing composite and mechanical expansion composite technology requirements of the law due to its own process, composite tube inside and outside the joint requirements for circular tube surface or inner tube surface, and the transmission cable and incompressibility of insulating material, conductance through drill pipe body ministry will appear in the cable joint department 'micro convex, thus drawing composite and mechanical expansion composite will damage to the insulation of the cable and performance, applicability is not strong. Hydrostatic pressure fluid force composite technology refers to the injection of high pressure water in the lining tube, with the increase of hydraulic pressure tube body lining tube, inner tube state by the elastic deformation to plastic deformation, and close to the outer tube body, when the inner tube pressure reaches a certain value, the outer tube body elastic deformation occurs, the inner tube and the outer tube body fit closely together, when the lining tube pressure after unloading, outer tube elastic recovery, the inner pipe and outer pipe body tightly into a whole. Through the hot metal pretreatment technology through hot metal pretreatment desulphurization & rarr; 120 t avoidances the combined-blowing converter dephosphorization & rarr; 120 t avoidances the combined-blowing converter ( Decarburization) → LF→ RH→ The slab continuous casting & rarr; Cold pack & rarr; 1500 mm HSM broadband timber & rarr; Coiling, trial production of X80 pipeline steel hot-rolled broadband. The results showed that the w of X80 pipeline steel slab ( T( O) ) For 81 & times; 10 - 6，w( N) 58 & times; 10 - 6，w( H)
