Q:What is the standard version of flanges?
The question is a bit difficult to answer. I use some commonly used criteria to explain it.The ASME B 16.5 -2009 defines the construction criteria for pipe flanges and flanged fittings, including the definition of the flange pressure grade, the temperature and pressure curve of the flange material, etc., and is a very detailed construction code. According to the two part of the flange, a flange sealing surface in the form, such as the process of the convex surface surface groove face ring joint face; two flange form, such as welding welding socket welding etc.!The definitions in EN ASME are similar to those in 1092-01-2007!. The difference is that the ASME defines a pressure rating of CLASS series EN, defined as the PN series, and differs in the size of the flange sealing surface and the flange form.HG/T 20592-2009, the latest 2009 edition of the Ministry of chemical flange standards on the basis of the largest reference to the definition of ASME and EN, but there are still differences. In EN 1092-01-2007, at the same level under different pressure, the thickness of the flange form may not be the same, but in HG/T we can clearly see that all the size of the flange flange form is used in EN integral flange thickness. Personal feeling of the Ministry of chemical engineering flange standard strict and logical, and EN and ASME still have a gap.
Q:Is the forged flange and cast flange raw material slab similar? Five
Now the steel raw materials are mainly ingot and billet, steel materials in the factory are indicated in the warranty on this; and casting or forging flanges and not directly related to see through what kind of flange is processed out of the process if it is casting, casting products. If it is after forging, is forging products, suppliers should be issued by the product warranty, product warranty can be seen by casting or forging. Technical specifications written is not allowed to use continuous casting slab, and if the product for the use of steel raw materials, then even forging products are not qualified, and I hope to help you.
Q:Flange valve Q41F-16C/P/R mark, specific meaning?
Q- ball valve, 4- flange, 1- through type, 16- nominal pressure 16 kg, c- cast steel, p- stainless steel
Q:Flange gasket RF600-6. What does this 6 mean?
6 indicates the pressure, 6 kg pressure flange
Q:Introduction of flange
Flanges (Flange), also called flanges, flanges, or flanges. 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.
Q:What's the meaning of the middle flange? What's the difference between the flange and the flange?
Fran: it's an exotic language. English Name: flange, flange is to make the two cavities connected to the protruding parts or components.
Q:Where are metal flanges usually used?
Electrostatic connecting line should be in accordance with the standards in Appendix H (informative) as shown in table H.1.Three. Specifications for design and construction of GB 50156-2002 gas station10.3.3 in * * hazardous areas of oil, liquefied petroleum gas and natural gas pipeline flange, hose ends the joint application of metal wire jumper. When the bolted flange connection not less than 5, in the non corrosive environment can be bridged.
Q:What does the 6 11/4 mark on the flange face mean?
6 inches, 1 right, 4 inches, 3 inches, 2 inches, 1, 2 inches of right.
Q:Where is the difference between the double flange limit expansion joint and the double flange transmission joint?
Double flange dowel joint can transfer the pressure thrust of the connecting piece (blind plate force) and error compensation line, reduce the damage of axial thrust of piping systems and equipment. Mainly used to connect the pump, valve, pipe and other accessories loose.I have a friend, Gongyi West Village Xin Xin pipe fittings factory production of these two products, you can consult, and I hope that my answer can help you
Q:Can you check the anti - tumor drugs from Hongkong to the mainland?
Hongkong can find peak pharmacy, you can mail back to the mainland, very convenient, and I hope to help you.
