Q:What does 1.6RF stand for in flange DN50-1.6RF?
1.6 means PN1.6MPA is 16 kg pressure, this is the old name, now called "PN16 RF" means that the form of sealing surface is sudden
Q:What does "flange WN150-25FM sch40" mean?
This is the WN standard HG 20592-2009 standard flange which is concave piece butt welding, FM, 150 is the nominal diameter of 6 "25 PN25 pressure, SCH40 is the flange interface, the wall thickness of the steel pipe butt SCH40; please check with standard.
Q:What kind of flanges do you have?
Categories: home improvement, building materials, two categories: pipe fittings, machine tools, accessories, flanges
Q:What does the flange mark PL100-25 FR 20 II represent?
PL welding plate flange nominal diameter flange, 100MM pressure: the pressure of 25 kg, RF sealing surface, 20 grade II steel forgings.Tag example:Nominal diameter 1200mm, nominal pressure 0.6MPa, with raised face plate welding steel pipe flanges with metric tube, the material is Q235AHG20592 PL1200 (B) RF 0.6 flange Q235ANominal diameter of convex 300mm, nominal pressure 2.5MPa, with inch tube hubbed steel pipe flanges, the material is 20 steel flangeHG20592 flange SO300 (A) M 20 - 2.5Nominal diameter 150mm, nominal pressure 16.0MPa, with the ring of the British pipe connection, with neck welding, steel pipe flanges, material 16Mn, steel pipe wall thickness of 10mmHG20592 WN150 (A) 16.0 flange S = RJ 10mm 16Mn
Q:What is the nominal diameter of a flange? What is the nominal diameter of a pipe?
The nominal diameter of the 1. flange refers to the inner diameter of the pipe to be matched with each other;2. the nominal diameter of the pipe is the inner diameter of the pipe (the diameter of the inner hole).
Q:What does "flange connection" mean?
Flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together, completed the connection.Some pipe fittings and equipment have their own flange, but also belong to flange connection.This connection is mainly used for cast iron pipe, lining hose, non ferrous metal pipe and flange valve, etc., the process equipment and flange connection is also using flange connection.The main feature of flange connection is convenient disassembly, high strength and good sealing performance. When installing flanges, the two flanges shall be kept parallel and the sealing surfaces of flanges shall not be damaged and shall be cleaned. Gaskets used for flanges shall be selected according to design requirements.Flange connection is an important connection way for pipeline construction.
Q:How about the flange type 16 kilograms, 25 kilograms and 40 kilograms?
The kilogram above means that the flange is welded to the pipe and can bear the pressure, that is, the nominal pressure. First determine the pipe pressure, and then the pipe pressure to determine the flange bearing pressure. The difference is that the wall thickness is different. The material is low carbon steel. Or there is another way: the pressure rating is different, 16 kilograms pressure level is low, 25 kilograms of pressure level is high. 25 kg can be used to block 16 kg pipeline, but 16 kg of 25 kg can not be blocked. Hope to be able to help you, thank you for being accepted
Q:What does "flange PL150-16RF" mean, PL RF? I know what 150-16 means
PL150-16RF said PL is the flange welding plate flange; 150 is the nominal diameter of 150mm; RF said sealing surface in the form is a projecting surface; the 16 is the pressure the pressure of 16 kg, or 1.6MPa.Flanges are also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe and is 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.
Q:About flange
Should mark "DN", is the nominal diameter of the code.Is the nominal diameter size after the roundness of the numerical repair to the mantissa, in order to simplify the mark.Germany, China ISO, nominal diameter are DN.
Q:What is flange connecting plate?
What we do in SINOPEC are all cross wiring, do two pieces of welding in the flange at both ends of the pipe wall, and then connected with copper wire.
