Q:Inside and outside the plastic coated steel plastic composite pipe to flange connection
The connection step is:1, press groove with groove machine.2, clamps one, the short pipe flange one, carries on the connection.3, after the connection, corresponding to the valve flange is OK, remember to see the number of flange holes in advance.
Q:Who can tell me what "DN" and "PN" mean in flanges, and what does PN16 stand for?
DN----- through the flange -- such as pressure DN15. with Phi 18 DN25.
Q:What is the output flange? What's the function?
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.Flange, threaded connection (wire), flange and welding flange.
Q:60 seamless steel tubes with 50 flanges, right?
The problem should be this, 60mm seamless steel tubes with DN50 flanges, right?Normally; diameter seamless pipe DN50 welding flange is 57mm, if it is seamless and DN50 matched flange 60mm, seamless processing thread, flange hole machining internal thread, so just.In the form of welding, the DN50 flanges need to be machined and they are also available.
Q:What does DN32 flange mean?
According to American Standard B36.10M 1-1/4 "is 42.2mm diameter is connected to the pipe is 42.2mm, the hole to see the pressure level or wall thickness determine the size
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:Can the aluminum flange 6061 and the aluminum tube 6063 be welded directly? Will there be such a fracture?
1, welding can be no problem.2, as long as the welding process is fine.
Q:PROE flat sheet metal design whole wall and the flange wall what is the difference?
but if not a lot of this piece of sheet metal bending, and the shape is not Affirmative square, with it is necessary to cut the flange murals one or several features.
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:What is the function of the flange stub?!
Different pressure flanges have different thicknesses and use different bolts. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. In the two plane in the vicinity of the use of bolted connections, and closed parts are generally referred to as "flange", such as ventilation pipe connection, this kind of parts can be called "flange parts."". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".
