[With seamless elbows straight section is our most professional] with a straight segment elbow, producing a straight section of the elbow, a lot of the process line with straight segments seamless elbow refineries, chemical plants and thermal power stations, heat pipeline The operating conditions of high temperature and pressure, so it is installed pipeline has a high demand, and even special requirements. Bend when connecting these lines are also required to use high quality, high strength, high temperature high pressure seamless elbow, otherwise, can not meet the needs of installation and construction, and the production and safety can not be guaranteed. The length of the straight section with the elbow method for producing a seamless straight section with elbow manufacturers, both ends of the pipe cross-section cut oblique incision, with a straight section having a length equal seamless elbow manufacturers with straight segments elbow , stopper inner mandrel when the pipe reaches creep deformation, the inner mandrel diameter equal to the inner diameter of the pipe, the shape of the inner mandrel for seamless elbows without straight section with straight segments elbow manufacturers. The other ends of the inner mandrel into the straight section of the horseshoe-shaped mold, then placed in a mold, clamping the pipe by press molding. Quality products of the invention meet the relevant standards, and low cost, the material can be fully utilized, not wasted. And lower processing costs, the present invention is particularly useful for large diameter elbow with a straight segment processing. Piping elbow is highlighted weaknesses in the reliability of the pipeline is mainly determined by the ability to work elbow. "Stress and its ability to work elbow which related to calculation and site of the pipe work stress measurement found to be particularly sensitive to bend the arc starting point of external loads. Remove the internal pressure and external load weight, etc. mainly piping at the start metal pipes during thermal expansion, piping vibration and abnormal work-hanger additional external load caused when the elbow is a sectional arc butt weld, external load will cause the weld these changes in a complex stress state, serious weaken the weld strength and reduce the ability to work elbow, elbow shorten life. To do this, from the design considerations, the interface into a straight section of butt welded elbow, that is designed to bend with straight segments, is conducive to welding butt, improve weld quality, improve the service life of elbow extension Hebei Thai Pipe Manufacturing Co., is a professional production of elbow, elbow with straight segments, straight segments with high pressure - high-quality seamless elbows factory, our company is located Beautiful fittings of all - Hebei Yanshan, since inception of the company has been the quality as the development of enterprises, and from raw materials to finished recheck final inspection, have been a complete set of management procedures and organization to control Thai Extension. Fittings sincerely welcome your call!
