Q:What is the two gauge flange? 5
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.Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different.
Q:WF face flangeI'd like to ask what flange form WF is,
written in WF flange?Supplement:1. flange connection points by welding, butt welding for (SO) (WN), socket welding (SW), (LJ), loose thread (PT).
Q:What does the flange 20592-MFM stand for?
MFM refers to the upper and lower flange of the matching structure of the sealing surface, is the concave convex surface of the matching: M is convex, FM is concave.
Q:What is the welded flange valve?
A welded flange valve is a valve installed on a pipe to weld flanges.Welding: welding, also known as the melt, is a kind of heating, high temperature or high pressure way of metal or other thermoplastic materials such as plastic manufacturing process and technology. To achieve the purpose of joining by welding in the following three ways:1. Heating the workpiece to be melted locally to form a molten bath. The bath is cooled and then joined. If necessary, the melt can be added to the melt;
Q:Shandong 03 fixed ventilation pipe flange production, installation, how to take charge?
The first chapter of the corresponding item to support.- fixed number: 9-546~749The eleventh chapter plastic ventilation pipe and components production and installationFour, the wind pipe production and installation projects include pipe fittings, flanges, reinforcement box, but does not include hanging support bracket, hanging support bracket, using the first chapter of the stent project.- fixed number: 9-590 interface and flexible expansion joint flange9-589 flexible interface and expansion joint without flange (pay attention to the difference between two quotas)The twelfth chapter of glass steel ventilation ducts and parts installationThree, glass steel ventilation pipe installation project, including three links, elbow, tube, pipe fittings and Tianyuandifang installation flange reinforced frame and the hanging bracket installation, not including the cross wind landing bracket. The landing bracket shall be calculated in accordance with the first chapter of the support project.- according to the above description, flange manufacture and installation has been included in the amount of wind control stability.
Q:The connection between the air outlet and the air duct can straddle the flange
Can not.The air outlet must be connected directly to the air duct. If the size of the air outlet is larger than the length of the air duct, a suitable length of air duct must be made to facilitate the connection of the air inlet.The reason is: according to JGJ141-2004 "ventilation pipe construction technical regulations" requirements, different specifications of the wind pipe have the corresponding stiffness requirements, otherwise, must be reinforced. The tuyere destroys the integrity of the flange, which affects the stiffness of the duct.
Q:What does the flange set contain?
If yes, it should include two sheets of flanges, gaskets, connecting bolts, nuts, if not specified: a pair of flanges
Q:In the heat exchanger calculation, the actual bolt section area of the cylinder flange is smaller than the required cross-sectional area. What's the matter?
Bolt strength shortage, improvement method:1, check the matching of bolts and gaskets... Do not use low strength bolts with metal gaskets or gaskets.. Unreasonable。
Q:What is the function of the flange stub?!
Flange is a kind of discoid parts, which is the most common in pipeline engineering. The edge has bolted mechanical structures, such as pipe joints, which can be bolted if flanges are attached to the flange. The flange cap is the flange of the cap and is bolted to the flange. Flanges are used in pairs.
Q:Flange PL40 (B)What does PL40 mean in flange PL40 (B) -1.6RF304HG20593-97?
HG20592-97 is the Ministry of chemical industry standard "welding flange plate steel pipe flanges" (European system), PL refers to the type of flange welding plate flange, (B) refers to the application of the pipe diameter B series (Metric), flange diameter DN40 nominal diameter is 46mm, with a 45mm diameter steel pipe.
