Q:Flange WN50 (B) -25 RF S=6 specific points
WN indicates that butt welding 50 means nominal diameter DN (B means B series diameter is 57) - 25 is pressure, new standard is 25 kg pressure, old standard is 250 kg pressure RF, sealing surface protrusion S=6 flange diameter thickness is pipe thickness
Q:Flange specification PL80-1.6RF
RF is the code for sealing form, is the process of meaning.
Q:Dn400 flange hole distance
HG/T20592-2009 20592-97 standards of the Ministry of chemical industry. The center distance is 2.5 kg -6 kg 10 kg (495) from the center (515) is 16 kg (525) is the center distance of center distance is 25 kg (550) 40 kg (585) is the center distance of center distance is 63 kg (585) 100 kilograms of center distance (620)
Q:Steel pipe can flange connection, aluminum pipe can flange connection?
Both flanges can be connected. The flange is the joint of the pipe and the pipe.Different media, the choice of flange material is different.You say plastic pipes can also come through flanges. Flanges are usually made of nonmetallic material.Teflon can also be done. The wear resistance of PTFE is chenchen.
Q:What's the size, size, size and weight of DN 1000 flanges?
It depends on what kind of flange you are talking about. What type and what standard can you correctly know about the quality of the flange you asked?
Q:What is the flange? What are its application areas and principles?
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.Flanges are widely used in construction, power generation, machinery and many other fields, and their main functions are as follows:1. Connect the pipe and keep the sealing performance of the pipeline.2, to facilitate the replacement of a section of the pipeline.3, easy to disassemble check the pipeline.4, to facilitate the closure of a section of the pipeline.Classification of flanges1. carbon steel, cast steel, alloy steel, stainless steel, copper and aluminum alloy are classified by material2., the production method can be divided into forging flange, casting flange, welding flange and so on.3. makes the standard can be divided into national standard (Ministry of chemical industry standard, standard oil, electricity standard), American Standard (ASTM), German standard (DIN), Japanese standard (JB).
Q:What is a stone flange?
Anti leakage: stitching seamless, smooth and smooth interface. Easy renewal: any serious damage such as burn marks, stains and cutting marks can also be restored by grinding procedures, so that the surface is as smooth as new.

Q:DN200 how many screws are there in the weld flange?
We want to know the welding flange of DN200. The 16 kg pressure is 12 screw holes. 10 kg pressure welding flanges are 8 screw holes. Welding flange in the field, all you need is a welding flange pressure of 16 kg, so we just get you 16 kilograms of welded flange welding flange connection, but in your site is not correct, your connection welding flange is 10 kg pressure.
