BHGH threaded hub flange

Q: Do I need flanges for rubber joints?: There are two carbon steel flanges at both ends of the product,Some customers also need counter flanges.

Q: A metal pipe nominal diameter 1200, using flange connection. In the original installation technical requirement, "parallelism: tolerance is 1mm/1000mm". How do you measure parallelism? What does this "1mm/1000mm" mean? How do you explain that?Another: flange roughness and how to measure and explain??: Parallel degree should be marked that flange mounting flange gap when the maximum and minimum width difference, the difference is not too large, is on the corner of the bolt flange sealing, not partial, or in some places more pressure gasket, gasket in some places may be there virtual pressure, although it does not leak, long time might be have a problem,As for flatness, the surface finish of machined surface should be considered as the flange sealing surface can not be a flat surface, and must be opened with mortise or groove

Q: What do butt welding flanges WN300-150, RF, Sch40 mean?: WN neck welding flange, bore 300mm, pressure 150 psi, pipe No. 40, standard pipe number, used to determine the inner hole of flange.

Q: 60 seamless steel tubes with 50 flanges, right?: Yes！ But more accurate description is: the outer diameter is 60mm seamless steel pipe, and nominal size of DN50 flange matching connection.

Q: What is a flange? Where is it usually used?: A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms.

Q: Flanges of different sizes: If the outer diameter is not big, the bolt hole, the middle diameter and the bore diameter can be unified. If the specifications are different and can not be directly connected, you can use the big head as an excessive.

Q: What are the specifications of orifice flanges? Be comprehensive: There is no standard flange hole is 6, in order to install the need, mainly to avoid directional (plus or minus 90 degrees, plus or minus 180 degrees), flange holes are 4 multiples

Q: What is flange? Why is it called flange?: Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.1, according to the chemical industry standard (HG): integral flange (IF), (Th), threaded flange welding plate flange (PL), neck flange (WN), hubbed flange (SO), socket welding flange, butt welding (SW) ring loose flange (PJ/SE), flat loose flange ring lining flange (PJ/RJ), (BL (S)), flange (BL).2, according to the petrochemical industry standard (SH): (PT), threaded flange welding flange flange (WN), (SO), socket welding flange (SW), loose flange, flange cover (LJ) (not note).3, according to the mechanical (JB) industry standard: integral flange, welded flange, welding plate flange, butt welding ring loose plate flange, welding ring loose plate flange, flange ring loose plate flange, flange cover.4, according to the national standard (GB): integral flange, threaded flange, flange, butt welding and hubbed flange hubbed socket welding flange, butt welding neck flanges, ring plate flange, butt welding ring loose plate flange, welding ring loose plate flange, flange ring loose plate flange, flange cover.

Q: Is the flange fitted with a flange?: However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".The movable flange is sheathed on the end of the pipe by using a flange, a steel ring, etc., and the flange can be moved on the pipe end. Steel ring or flanging is the sealing surface, the role of the flange is to compress them. Thus, because of the steel ring or flange block, the live flange is not contact with the media. Because the flange is movable, not directly connected to the pipe, so it is called "live flange", there is another statement called loose flange.

Q: please detail the flange parameters. 10Also, can you tell me where the flange reference standard should be downloaded?: Two, PL200 (B) -16RFPL is the welding plate flange, 200 is the nominal diameter of 200mm (B) is the use of metric tube (also known as GB tube), 16 is the nominal pressure is 16MPa, RF is a prominent surface seal seal type.Specific flange parameters are not clear, this is HG20592-20635 "steel pipe flange" standard flange.
