Q:What are the welding flanges and blind plates for?
The flange is a fitting process of pipe connections, according to connection method can have threaded flange, flange welding (welding welding and butt welding flange); blind plate in the end of the pipeline plugging, welding and blind flange (flanged cover bolts); the three is the finished fittings made to convenient connection tube in the pipeline. Refer to positive three links: the main and branch diameter equal diameter three: main and branch diameter range, and special with three etc, can live in the pipeline opening through making three low voltage, but high pressure pipeline must be specially made for the finished three, three can be divided according to connection welding and threaded flange type; reducer is pipe diameter when used for pipe diameter DN100 now wants to become a DN80 diameter on the need for a DN100 * 80 big head; head connection is also divided according to the size of welding, flange and a screw type; a pipe hoop is connected with pipes without welding on the line, where the interface card is galvanized; flange flange surface is galvanized, galvanized the same three is three surface is galvanized, the difference between them is that one is three through a flange are pipeline Enclosure。 The expression of each pipe is PN, XX, DN, XX, plus national standard drawing number to define a pipe fitting. Galvanized pipes are generally used in low pressure, low temperature fluid delivery processes, pipelines, or municipal pipelines.
Q:What is the connection between the valve and the flange seal?
You need to see how thick your pipe is Match the DN150 flange and, of course, the wall thickness to match
Q:What is the inner flange?
Flanges that connect internal parts and pipes within the equipment generally do not withstand pressure loads
Q:What is the difference between a threaded connection and a flanged safety valve?
There is no difference in useJust the connection is not the sameThread connection is mainly used for small caliber valve, 50mm or soFlanges are generally used in large and medium-sized safety valves
Q:Are flanges standard ASME and ANSI universal?
The 1988 edition of "pipe flanges and flanges" is labeled "ASME/ANSI B16.5-1988" and "ASME/ANSI" is the same. But since the 1996 edition, ANSI has begun using the new logo: ASME B16.5-1996, and so is the latest version 2003. Thus, since 1996, ANSI has completely accepted and adopted ASME pipe flanges and flanged fittings. For a more detailed history of development, you can read the B16.5 introduction.Other ASME standard flange you look at it, I have not used, do not know, do not talk nonsense.
Q:What's the flange cover BL20-100FM?
The flange cap BL20-100FM is: 20 is nominal diameter, 100bar is the pressure grade, and FM is the sealing surface form - concave surface
Q:What is the difference between the HG/T20615-2009 flange standard and the ASME B16.5 flange standard?
The size of HG/T20615-2009 and the ASME basic B16.5 agreement, is China standard in American Standard standard, and ASME is also the basic material.
Q:What is the flange of the stamping parts? What is the specific surface of the flange mentioned in the stamping die?
A flat outer surface or abrupt step that has an opening, a concave, or other shaped depth
Q:What does DNPN mean by flange?
One is the caliber, the other is the pressure
Q:Are flanges and flanges a kind of thing?
Is the same product, but is not the same as the name, flanges, flanges, flanges are all a product. For a threaded connection pipe and valve used or welded pipe fittings, the main producing area in Mengcun County, we are specializing in the production of this product, Hebei wealthrun Pipe Industry Co Ltd.You can go to Baidu encyclopedia, then the flange and flange entries on the merger.
