Where good quality flange? Hebei Thai Extension Pipe Manufacturing Co., Ltd. is your choice, our company is a production of flange flange, large blind flange with old factory neck flange and other products over the years With reasonable price, excellent quality, excellent service, the praise by many customers, warmly welcome new customers to come to visit and negotiate business! high alloy flanges are made of high alloy flange, high alloy flanges Many species, there are sets of welded flange, welded flange, Looper flange for valves, pumps, chemical machinery, petrochemical machinery, piping and other equipment attachment flange screw connection points (wire tapping) flange and welding flanges. Low pressure small diameter wire flange, high pressure and low pressure large diameter are using welding flange thickness and bolt diameter and the number of different connection flange pressures are different. Production processes are forging, casting, plate rolling, plate cutting system, of which the highest price forging, plate products second, casting products to a minimum. On the quality, the forging of the best, rolled a second, casting the third. But forging caliber generally small. High Pressure Flange focus is unique to the new metal to metal seal, which rely on the sealing lip of the sealing ring (T-shaped arm) is elastically deformed to form a seal, are hard seal; then operate the hub, card sets, the seal ring bones combined to form a strong rigid body, the strength of joints is far greater than the strength of the pipe base metal itself. Flanged steel pressure valve combined with medium: water, oil, steam and so on. High pressure flange connection is the two pipes, fittings or equipment, each mounted on a first flange between two flanges, with flange pad, fastened together with bolts to complete the connection. High pressure flange connection is the two pipes, fittings or equipment, each mounted on a first flange between two flanges, with flange pad, fastened together with bolts to complete the connection. For this problem, we all must choose gasket problems. Thus, when we were mastering the above three standard, then the high pressure flange stepping on it.
