Q:What's the thickness tolerance of neck flange?
Specification for JB/T74-1994 pipe flangesSH3406-1996 steel pipe flanges for petrochemical industrySpecification for GB/T17241.7-1998 cast iron pipe flanges
Q:Dn is 250, Pn25 flange, what is the hole distance?
Flange center hole distance d1=370mmFlange diameter D=425Aperture 30Bolt M27
Q:How should we get to know the flange?
What's the flange? Most books say this: flanges and their gaskets and fasteners are commonly referred to as flanged joints. Flange joints are widely used in engineering design and involve a wide range of parts and components. It is a pipe design, pipe fittings, valves indispensable part, but also other industries, such as heat, water supply and drainage, heating, ventilation, automatic control and other projects in a commonly used components.That may be very standard, but understand the people may be less.
Q:What is flange? Why is it called flange?
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. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. 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. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". 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".
Q:What is the standard version of flanges?
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:When the toilet is fitted with flanges, is the rubber side of the flange facing the floor or the toilet? The installation is more reasonable
1, the rubber ring side is toward the toilet, so that the toilet seat in the water outlet is easy to correct, it is best to ground glass glue, so that sealing is more difficult to leak.2, the flange ring is the sealing ring, also known as gasket. Currently more popular is the wax seal ring, also known as the wax sealing ring. Among the many industrial bearing to shock and wear resistant rubber pad called flange, basically need to use the toilet installation flange, but a lot of the toilet to reprovision. There is butter, polymer, the latter is more popular. The toilet (toilet flange seal) is put down the hole and the bathroom in the outfall, seals play a role, so that the siphon toilet flushing does not leak, the effect is very good.
Q:What is blind through flange?
For the blind flange end of the pipeline, to shut off the pipeline
