Q:Introduction of flange
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.
Q:What's the difference between a clip flange and a flange?
Flanged butterfly valves are flanged on the valve and bolted to both ends of the valve to connect the flanges to the pipe flanges. Sealing surface wear resistance, long service life. The utility model has the advantages of unique structure, flexible operation, labor saving, convenience, and high and low pressure without the pressure of the medium
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?
Generally choose JB/T4700-2000 "pressure vessel flange" in the flange, you do not need to calculate
Q:What's the price of a stack of 600 carbon steel flanges?
Flange connection or flange connection, is defined by the flange, gasket and bolt connection between the three sealing structure of the detachable connection as a combination of group pipe flange refers to the pipeline installation of piping flange, used in equipment refers to equipment import and export flange. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges.
Q:What's the flange body?
Flanges (Flange) are also called flanges or flanges. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe.
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:About flange 5
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:Shandong 03 fixed ventilation pipe flange production, installation, how to take charge?
There are five chapters in the consumption quota of installation engineering in Shandong Province, including 1, 9, 10, 11 and 12 chapters. The corresponding categories are thin steel plate, stainless steel plate, aluminum plate, plastic and glass fiber reinforced plastic. Following, in accordance with the instructions in order, followed by instructions.The first chapter of the production and installation of steel sheet gout pipelineFirst, this chapter includes galvanized steel duct, ordinary steel duct, galvanized steel pipe (no flange connection), fan coil bracket accessories, connecting pipe, ventilation pipe production installation and flexible hose installation, a total of seven 30 items.
Q:What's the difference between RF flange and RJ flange?
The difference between the RF flange and the RJ flange is that the seal is different.RF flange is a face seal surfaceRJ flange is ring connection sealing surface
Q:What are the advantages of a flanged plunger valve?
The structure characteristics of the plunger valve is composed of a stainless steel plunger, two elastic sealing ring and a metal frame, the sealing effect by the plunger and the seal ring is closely fitted to the plunger, inserted in the two sealing ring, the sealing area is far greater than the ordinary valve; switch plunger valve, the piston moves slowly in the the sealing ring, the contact surface is almost not wear off, the plunger is inserted into the lower sealing ring, truncated channel; open, although from the plunger seal, but still hiding in the ring, remain isolated from the outside, not to leak.The sealing ring is a science and technology product. It is the key component of the plunger valve. It consists of polytetrafluoroethylene, graphite and high elastic rubber. It can provide good sealing performance after millions of times of reciprocating movement test. Meanwhile, the valve has small opening moment, large sealing area, wide application medium, high temperature adaptability, reliable sealing, long service life, convenient maintenance and the like. Widely used in petroleum, chemical, power, pharmaceutical, food, textile, printing and dyeing, boilers, machinery and other industries.
