The company mainly produces supply elbows, flanges, reducers head size, IF big elbow, Tee, plate welded flange, socket welding flange, threaded flange, flange covers, which are widely used in water, electricity, power plants, pipe fittings, industrial, pressure vessels, HVAC, building water pressure vessel parts, gas pipeline projects, chemical plants, power plants, shipyards, pharmaceutical, dairy, beer, beverage, fire, gas, hot and cold water , air conditioning, air pipe, tubing, instrumentation, hydraulic pipes and other industrial and civil pipe thread locking and sealing. (Flange) also known as flange or flange. The tube and pipe parts connected to each other, connected to the pipe end. There are holes on the flange bolts so that the two flange abuts. Between flange sealing gasket. Flanged pipe fittings (flanged pipe fittings) refers tube with a flange (flange or disk access) for. It can be cast from (figure available), may also be threaded or weld composition. Flange connection (flange, joint) by a pair of flanges, a gasket and a number of bolts and nuts. Gasket is placed between the two flange sealing surface, tighten the nut on the gasket surface pressure than the deformation reaches a certain value, and fill the sealing surface uneven, so that does not leak tight connection. Flange connection is a detachable connection. 1 Press the coupling parts can be divided into vessel flange and pipe flange. By structure type, with integral flanges, loose flanges and threaded flange. Common integral flange welded flange and welded flange. Less rigid welded flange for pressure p ≤ 4MPa occasions; welded flange, also known as high-neck flange, greater rigidity, suitable for high pressure and temperature applications. 2 flange screw connection points (wire connection) flanges and welded flanges. Low small diameter wire flange, high pressure and low pressure are using large-diameter welded flange thickness and bolt diameter and the number of different connection flange pressure is different. Welcome new and old letter to inquire!
