Q:What is the welded flange valve?
A welded flange valve is a valve installed on a pipe to weld flanges.Welding: welding, also known as the melt, is a kind of heating, high temperature or high pressure way of metal or other thermoplastic materials such as plastic manufacturing process and technology. To achieve the purpose of joining by welding in the following three ways:1. Heating the workpiece to be melted locally to form a molten bath. The bath is cooled and then joined. If necessary, the melt can be added to the melt;
Q:What's the flange? What's it for?
Flange (Flange), also called flange or flange plate. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. It is also used for the flange on the inlet and outlet of the equipment. It is used for the connection between the two devices, such as the reducer flange. 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. Sub threaded flange connection (threaded connection) flange and welding flange and flange clamp.
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:Flange DN25 PN4.025 what does it mean? 4, what does it mean?
1, DN25, DN as the nominal diameter of the sign, note that 25mm refers to the approximate diameter reference size;2, in the valve industry, PN as nominal pressure symbol, and make the value of PN after the value of MPA, PN4.0, its nominal pressure value is 4.0Mpa
Q:Why use special flange for butterfly valve?
Because the diameter of flange butterfly and butterfly valve is just DN inner diameter matched a slot in the back, and this is the connection of the steel pipe is inserted into the slot, so as to ensure the sealing effect, but with a flange piece of ordinary cannot guarantee the effective sealing effect.Butterfly valve plate installed in the direction of the diameter of the pipe. Butterfly valve structure is simple, small size, light weight. Consists of only a few components.
Q:Where is the mansion in the mirror city of magic baby?
Enter here at flange city coordinates 96148;But you need a charm, a red rosary;
Q:What is the maximum pressure of the flanges RF and RTJ?
The use of with concave convex surface with tongue and groove face flange is basically the same. Ring groove sealing surface (RTJ) is mainly used in high temperature and high pressure or both high working conditions. In American Standard flange, commonly used in Class 600Lb (part) and 900Lb, 1500Lb, 2500Lb grade pressure. In the German standard and national standard, often used in PNl0.0, PN16.0, PN25.0, PN32.0, PN42.0MPa flanges.
Q:I am learning machinery, there is a book in the book, LAN type,
According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal padFlange connection is easy to use and able to bear greater pressureIn the industrial pipeline, using flange connection is very extensive. Within the family, the small diameter of the pipe and low pressure, see flange connection. If a boiler room or a production site, everywhere is the flange connection of pipes and equipment.
Q:CF, ICF, is the flange the same?
The ICF flange (ConFlat Flange) has a raised sharp edge inside it. It is made of all metal sealing parts by squeezing the copper gasket to deform it to achieve the purpose of sealing vacuum. Widely used in ultra high vacuum field equipment.
Q:How should we get to know the flange?
Flange forging forging casting iron and casting into a two GB standard and non standard to distinguish various standards, including some foreign standards.Such knowledge is not to be taught, but to be learned
