Q:What is a flange? Where is it usually used?

About flange what is this problem, in the Internet search for a long time, only to find the answer, do not know can help? Look, you must read it after looking for such a hard job, though it's a bit boring.Flanges (Flange), also called flanges, flanges, or flanges.

Q:How many kinds of flanges are there?

4. according to the material for making flangesAccording to the flange material can be divided into: cast iron flange, steel flange, plastic flange, copper flange and so on.At the same time, there are 4 standards for flanges in our country, namely, versatility and specificity. Each flange standard is not limited to the scope of this trade, but it is crossed and permeated. In order to gradually unify the flange standard, the National Machinery Committee has formulated a series of flange standard, where GB/T9112~9124 - 2000 "steel pipe flange" series standard is quite comprehensive, but this does not mean the national standard to replace the other flange standard. HG/T20592~20635 - 2009 "steel pipe flanges, gaskets and fasteners" is adjusted and revised based on the original HG/T20592~20635 - 1997, which is set by European and American system system respectively in the preparation of pipe flange standard system, clear and operational use.

Q:What do you mean by flange?

1. flange flange connection flange (flange) connection is an important connection pipeline construction. Flange connection is the two pipes, fittings or equipment, each first fixed on a flange on the flange between the two, and flange pad, fastened together with bolts, completed some fittings and connected. Equipment have built flange, flange connection also belongs. Sub threaded flange connection (wire) flange and welding flange. Low voltage and small diameter wire flange, high pressure and low pressure are the use of large diameter welded flange, different pressure flange thickness and bolt diameter and the number is different according to different levels of pressure. The flange pad also has a variety of materials, from the low pressure and high pressure asbestos asbestos pad pad to the metal pads are flanged. Easy to use, able to withstand greater pressure. In the industrial pipeline, flange connection is very wide Pan. 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. Also called flange or flange. The pipe and pipe interconnected parts. The holes are connected to the pipe end. Flange wear, bolt, so that the two flange abuts. The flange gasket seal. Flanged fittings (flanged pipe fittings) with a flange (flanged or disk) pipe. It can be cast into a (figure not available), may also be threaded or welded flange connection (flange,. Joint) composed of a pair of flanges, a gasket and a plurality of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, so that does not leak tight connection. The flange connection is a removable contact Answer.

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:How about copper tubes? TenCan plastic pipes be flanged? Can it bear the pressure of the bolt?

The steel pipe, the aluminum tube and the copper pipe can be flanged connected.Flange connection is the two pipes, fittings or equipment, each first fixed on a flange plate, and between the two flange with flange pad, finally by bolt two flange of a detachable joint tension so closely together.purposeThis 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.
