ASTM/API Carbon Seamless/welded Steel Pipe

Q: A metal pipe nominal diameter 1200, using flange connection. In the original installation technical requirement, "parallelism: tolerance is 1mm/1000mm". How do you measure parallelism? What does this "1mm/1000mm" mean? How do you explain that?Another: flange roughness and how to measure and explain??: Parallel degree should be marked that flange mounting flange gap when the maximum and minimum width difference, the difference is not too large, is on the corner of the bolt flange sealing, not partial, or in some places more pressure gasket, gasket in some places may be there virtual pressure, although it does not leak, long time might be have a problem,As for flatness, the surface finish of machined surface should be considered as the flange sealing surface can not be a flat surface, and must be opened with mortise or groove

Q: Flange German standard DIN, pleaseND16 what does that ND mean?It's ND in German standard DIN, not nominal diameter DN: ND refers to nominal diameter, approximate pipe internal reference dimension.Nominal diameter is not equal to outer diameter -2 times double thickness

Q: One side is flat plate and side hubbed flange can be connected to it: The same standards, the same pressure, the same caliber, with these three points can be connected

Q: Flange SO40-2.: Now the method is SO 40-25 M.Refer to HG/T20592-2009 steel pipe flanges (PN Series)

Q: What's the meaning of the middle flange? What's the difference between the flange and the flange?: Fran: it's an exotic language. English Name: flange, flange is to make the two cavities connected to the protruding parts or components.

Q: Dn400 flange hole distance: Could you tell me the pressure and standard of the flange?

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: How many kinds of flanges are there?: 1. The flange is divided into flange, flange, threaded flange, socket welding flange and loose flange according to connection.2. according to the form of flange sealing surfaceFlange in accordance with its form of sealing surface can be divided into flat, convex surface, concave convex surface, tongue and groove surface and ring connection surface. There are 4 standards in our current flanges: National Standard (GB/T), machinery industry standard (JB/T), Sinopec General Corporation Standard (SH) and chemical industry standard (HG). The standard of the sealing surface of the name is different, see the table below the name of the sealing surface.Table cover name contrastSealing surface nameNational standard(GB) chemical industry standards(HG) Sinopec General Corporation standards;(SH) machinery industry standards;(JB)Plane plane (FF) full plane (FF) whole plane (FF) -Convex surface (RF), convex surface (RF), convex surface (RF), convex surfaceConcave convex surface, concave convex surface (MF), concave convex surface (MFM), concave convex surface (MF), concave convex surfaceTongue and groove face, groove face (TG), tenon (TG), tenon (TG), tongue and groove faceRing connection surface, ring connection surface (RJ), ring connection surface (RJ), ring connection surface (RJ), ring connection surface

Q: If the end is threaded on both sides of the blind hole, and not in the same circumference, whether the flange, why?: The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Flange, threaded connection (wire), flange and welding flange.Flange connecting has threaded hole, also is not uniform in the same circumference, mainly to see the effect, whether for connection;

Q: What are metric tubes and British tubes? What's the difference between them? How do you choose flanges?: It should be the metric tube and the British tube, that is to say, the B series and the A series.According to the flange diameter of the steel pipe, the flange diameter should be chosen according to the outer diameter of the steel pipe.The national standard flanges sold on the market are generally B series, and the A series shall be noted.My company website has flange standard, and corresponding steel pipe size.
