Q: Where is the difference between the double flange limit expansion joint and the double flange transmission joint?: Advantages: a large amount of expansion, convenient installation. Features: applicable to both ends of the upper flange connection pipe

Q: Flange German standard DIN, pleaseND16 what does that ND mean?It's ND in German standard DIN, not nominal diameter DN: 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: For flange who is more detailed explanation? For example, how to position?: The flange of the material according to the production of material can be divided into: WCB (Tan Gang), LCB (low temperature Tan Gang), LC3 (3.5%, WC5 (1.25% chromium nickel steel) 0.5%, WC9 (2.25% Cr Mo steel), C5 (5%), C12 (% Cr Mo) 9% Cr 1% mo (4), CA6NM (12% steel) CA15, (4) (12% CR), CF8M (316 stainless steel, CF8C (347) CF8 (stainless steel), stainless steel 304), CF3 (304L stainless steel), CF3M (316L stainless steel), CN7M (alloy steel), M35-1 (Meng Naier), N7M (Haast B, CW6M nickel alloy nickel alloy (Hasta) C (CY40), Inconel) 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, the tight connection. A flange connection is a detachable connection. The connecting parts can be divided into containers, flanges and tubes; in accordance with the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange welding flange, large rigidity, suitable for high temperature pressure. Flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, suitable for flammable and explosive, toxic medium and high pressure situations.

Q: I would like to ask this flange type in the end what is the shape, why is it called flange type?: 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.

Q: What is blind through flange?: For the blind flange end of the pipeline, to shut off the pipeline

Q: Inside and outside the plastic coated steel plastic composite pipe to flange connection: In a shell of an electron tube, there are more than two electrode systems, each of which is independent of the electron flow to achieve its respective functions. This tube is called a composite tube. A composite tube is a combination of two or more transistors in accordance with a certain law, which is equivalent to a triode, and the compound tube is also called a Darlington tube.Composite pipes are divided into two categories: one is an ordinary composite pipe, and the inner no protection circuit; the middle and small power composite pipes like 2W are mostly such; and another kind of internal protective circuit is such a kind of high-power composite pipe. The following table shows the main characteristic parameters of the silicon NPN type high-power composite tube.

Q: What is the meaning of flange PL50-16RF: Flange, nominal diameter 50mm, voltage 1.6MPa, convex seal type.Flange generally referred to as flat, also called a welding flange. Connecting flange and pipe is the first tube inserted into the flange hole to a proper position, then take welding.

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.

Q: What is the waterline of flanges?: Its function is to form labyrinth seals when flanges are connected to reduce leakage of gas or liquid!Prepare a chart, but not.In addition, if the flange is connected with a non-metallic gasket, it is only possible to process the sealing water line; if the metal gasket is sealed, the water line is not processed.

Q: Flange gasket RF600-6. What does this 6 mean?: Flange gasket RF600-6 in this representation method, several letters and data are defined as:RF corresponds to the form of the normal half surface, and belongs to the RF face flange600: nominal diameter is 6006 representative: this flange pressure rating is 6Bar
