Hebei Thai Extension pipe is welded seamless elbow Hebei region renowned manufacturers, Hebei is the largest plant of a seamless elbow, seamless elbow my company sold throughout the country, for the major engineering enterprises convenience, is the largest one in Hebei welded seamless manufacturers, good quality elbow my company, durable, seamless elbow elbow mounds areas most used by the manufacturer is out of our plant, I uphold the company has been the concept of service to our new and old customers are welcome to visit the new and old customers seamless large-diameter welded steel elbow is hot pressing or forging molding of the elbow, which is directly connected to form the elbow welded steel pipe, welded elbow major manufacturing standards generally GB / T12459, GB / T13401, ASME B16.9, SH3408, SH3409, HG / T21635, HG / T21631, SY / T0510, GB / T10752-1995. (1) welded elbow by its radius curvature can be divided into long and short radius bend radius butt welded elbow. Long radius of curvature equal to the radius of welded elbow 1.5 times the pipe diameter, i.e., R = 1.5D. Short radius of curvature equal to the radius of welded elbow pipe diameter, i.e., R = 1D. Where D is the bend butt head diameter, R is the radius of curvature. (2) If the press pressure rating points, about seventeen species, and the US standard pipe is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80 , Sch100, Sch120, Sch140, Sch160, XXS, one of the most common STD and XS are two kinds. (3) The angle of bend points, 45 degrees welded elbow, 90 degree and 180 degree butt welded elbow bend. My company has advanced steel tube and pipe fittings manufacturing equipment, products include carbon steel, alloy steel, stainless steel and other steel pipe, high, medium and low-pressure pipe, pressure vessels, power plant pipe fittings, miscellaneous power plant components factory configuration pipe, corrosion resistant pipe insulation, spring hangers, mechanical conveyor systems, a variety of small pieces of metal type, the company's corporate philosophy is that the customer comes first, integrity first, mutual caring, active learning, quality policy, quality First, accurate delivery, reasonable prices, courteous service.
