Dingxiang thriving iron forging factory production of flange execution ANSI16.5, DIN, Japanese standard JISB2220, B2210 and other national standards, the main varieties are: welding, lap, socket, sliding sleeve, thread, blind plate, plate and so on seven varieties, 1/2 "- 64", more than 20 kinds of specifications, the small make up today for you to explain the benefits of high butt welding neck flange.

High butt welding neck flange are mainly high neck, stiffness and bearing capacity of the flange. Its purpose is to transfer pressure pipeline, to disperse the stress concentration, butt welding flangeAlso known as the high neck flange, large rigidity, suitable for the occasion of high pressure and temperature. The main production process has the whole forging, forging manufacturing and casting, rolling, etc. The main production equipment has lathe, drilling machine, CNC machine tools, etc. Application: apply to the boiler pressure vessel, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food and other industries. Installation is convenient, can omit weld knead injury process. According to the standard are flat - GB9115.1 butt weld steel pipe flanges, convex butt weld steel pipe flanges - GB9115.6.

Butt welding flange including a circular ring set of ontology, ontology is the center of the diversion channel is set up, body corresponding to the diversion channel lateral position setting several number of connection holes, the axial end of the body surface with convex sets, ontology of axial set on the other end of the taper connecting tube, axial end face of the convex set on the ring grooves. This product is able to effectively improve the effect of butt welding flange sealing. Buy high butt welding neck flange forging factory to dingxiang flourish iron industry!
