Applications Technical seal nominal PN, MPa (bar) 0.6 1.0 1.6 2.5 4.0 6.4 convex surface (MFM) DN1300 ~ 3000 DN300 ~ 3000 DN400 ~ 2000 DN300 ~ 800 tongue and groove (TG) DN1300 ~ 3000 DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 800 whole plane (FF) DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 800 welded flange includes a plate flat welding flange, with neck flat welding flange, with neck flange. Flat welding flange for nominal pressure of not more than 2.5MPa pipe connection. Flat welding flange sealing surface can be made smooth style, bump-type and tenon slot three. Smooth application of the maximum level of welding flange. used for medium conditions are mild cases, such as low pressure non-compressed air purification, low circulating water. Flange Standard: HG20592-2009 (PN series) \ HG20615-2009 (Calss series) with a neck flat welding flange (HG20592-2009 (PN series) \ HG20615-2009 (calss series), GB / T9116), neck height low stiffness of the flange carrying capacity increased. Compared with welded flange, welding workload, electrode consumption is high, it can not withstand high temperature and pressure, and repeated bending and temperature fluctuations, but on-site installation more convenient, you can omit the step of weld rubbed film hurt more popular. Welded Flanges: Welding neck flange is generally referred to as "high-hub" flange. The aim is to divert pressure pipes, thereby reducing the high stress concentration in Frankie. Neck flanges butt welding is the best design value of those present, because of its inherent structural Flange. It is expensive, because of the design. Thread (thread) Flange: The flange threaded flange is similar to slide, but the hole threads. Its main advantage is that it can not welding assembly, in an extraordinary interpretation of atmospheric temperatures in the low-pressure service and highly explosive region, welding create a hazard. Sliding flange: sliding flange has a lower hub because the pipe flange welded into the top single. It is welded inside and outside to provide sufficient strength to prevent leakage. Sliding flange, matching are bored slightly larger OD tubing. They are better than the neck flange welding, due to lower initial cost, a lot of users, but probably not the final installation costs than, less because of the increase in weld neck flanges. Lap Flanges: in fact, exactly the same lap flange sliding flange, unless it is a radius between the hole and the flange race. This is necessary to accommodate the overlapping radius flange stub end. Typically, at the end of lap lap stub mating flanges and will be equipped with the system together. The socket welding flange is similar to a sliding flange, unless it has a hole and anti-hole size. Counter bore little beer than matching OD pipe to make the pipe inserted into the flange similar slide flange. In the smaller hole diameter is the same as the ID matches the same pipe. Restriction orifice is built as a dedicated pipeline shoulder sleeve stays at the bottom. This eliminates any traffic restrictions in the use of socket welding flanges. Flange Standard: HG20592-2009 (PN series) \ HG20615-2009 (Calss series) socket welding flange (SW) Socket Welding Flange sealing surface form: raised face (RF), uneven surface (MFM), tongue and groove ( TG), ring joint face (RJ) manufacturing standards: ANSI B16.5, GB / T9117.1-2000-GB / T9117.4-200, HG20592-2009 (PN series) \ HG20615-2009 (Calss series) Thread law Portland nominal diameter: DN8 ~ DN100 Working Pressure: 1.0 ~ 2.5 (MPa) plate threaded flange material: stainless steel, carbon steel, alloy steel. Threaded flange Application: Suitable for fire, gas, hot water, air conditioning, air pipe, tubing, gauges, hydraulic pipes and other industrial and civilian pipe thread locking and sealing. Flange cover, also known as blind flanges, intermediate flange without holes for pipes sealed with a plug. The type of sealing surface in the form of more, there are flat, convex, concave and convex surfaces, tongue and groove, ring joint face. Sealing surface: plane (FF), raised face (RF), uneven surface (MFM), tongue and groove (TG), ring joint face (RJ) weld neck Loose ring flange welded ring Falan Song Song cuff neck flange welded ring Loose plate flange with weld ring Loose plate flange plate over the loose flange In addition, to meet the needs of post-locking device, the rod portion with a hole, the holes can be flange (Flange), also known as the flange or flanges. Tube and pipe flanges are so interconnected parts, connected to the pipe end; also useful equipment import and export on the flange for connection between the two devices, such as a gear flange. Flange connection or flange joint, is defined by flanges, gaskets and bolts of the three connected to each other as a group combined seal structure removable connection pipe flange means conduit means piping flanges, used in equipment means the outlet flange on the device. There are holes on the flange, so that the two flange bolts tightly connected. Between flange sealing gasket. Threaded flange points (threaded connection) flange and welding flange and clip flange. Reducer flange for connection to the motor and gearhead connection, as well as gear and other devices. Flange connected by a pair of flanges, a gasket and a number of bolts and nuts. Spacer placed between the two flange sealing surface, tighten the nut, the pressure over the gasket surface deformation reaches a certain value, and fill the sealing surface uneven, the connection does not leak tight. Flange connection is a detachable connection. According to the connected components can be divided into the container flange and pipe flange; by structure type, with integral flanges, loose flanges and threaded flange. Common integral flange having welded flange and welded flange. Less rigid flat welding flange, for pressure p≤4MPa occasions; also known as high-neck flange welded flange, greater rigidity, suitable for high pressure and temperature applications. Type flange sealing surface in three ways: planar sealing surface, the pressure is not suitable for high, medium nontoxic occasions; uneven sealing surface for higher pressure Chinese name: Flange English Name: Flange categories: mechanical parts Scope : Hebei Pipe Manufacturing is still a constant construction, heavy industry, plumbing, electricity, etc., Ltd.
