Q: Do I need flanges for rubber joints?: There are two carbon steel flanges at both ends of the product,Some customers also need counter flanges.

Q: What do you mean by flange?: According to the connected components can be divided into container flange and pipe flange. According to structure type, integral flange, loose flange and threaded flange. Integral flange are common 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 flange, rigidity, suitable for high pressure and high temperature conditions. The 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, for Yu Yiran, explosive, toxic medium and high pressure the occasion. Gasket is a can produce made of plastic deformation, and has a certain strength of the material.

Q: Where are metal flanges usually used?: Two 、 DB 42512-2008 flammable and explosive places lightning protection device and anti-static grounding device testing technical specifications6.2.2.2 oil and gas pipeline system6.2.2.2.1 inspection of long distance no branch pipeline and pipeline, in the process area (including production workshop, plant, storage tank, etc.), bifurcation should be set as required, grounding, testing its grounding resistance6.2.2.2.2 check the pipeline within the building 100m, should be ground once every 25m, test its grounding resistance6.2.2.2.3 check the parallel pipe spacing is less than 100mm, every 20 to 30m for electrical connection, when the pipe crossing and the net distance is less than 100mm, should be electrical connection, test its electrical connectionCheck the flange should be cross pipe connection, in the non corrosive environment of not less than 5 bolts can not cross the transition resistance testing flange bridging material specifications.

Q: what is the difference between this, and when what form of connection ah?: To clip type, general caliber is small, pressure is not big. Flanges are suitable for large bore, and others have been answered

Q: I checked a lot of standards and marked a F1, but I couldn't find the corresponding size in the corresponding manual! Good halo: Only the weld ring loose flange is marked with a higher flange flange height. Moreover, different levels of C in the standard flange thickness has been set to die, your height suddenly face protruding at the flange thickness meet the appropriate process to face, is usually a value of experience, what is the scope of a DN, but the protruding height is not high, are generally small according to DN, increased, increasing

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: What's the difference between a clip flange and a flange?: This problem, mainly refers to the butterfly valve in two forms, pairs of clamp and flange type:The clip butterfly valve (valve itself without flange) is a double headed bolt to connect the valve between the two pipe flanges. The clip butterfly valve is simple, small and light in weight and consists of only a few components. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics.

Q: WoW World Mission, where is the French die cutter?: First of all, you have to go down to the bottom of the cave. There will be a spider layer on the bottom. There's a lot of cobwebs on the net, and you'll have a chance to throw them out when you attack them

Q: Shandong 03 fixed ventilation pipe flange production, installation, how to take charge?: Two, work content:1, the wind pipe installation: with the reserved holes, wind pipe, elbow, three links, reducing pipe, pipe fittings, flanges and other Tianyuandifang reinforcement frame, hanging bracket mounting, derusting, painting wind pipe and steel.- according to the above description, flange manufacture and installation has been included in the amount of wind control stability.The ninth chapter of stainless steel plate and components production and installation of ventilation pipeFirst, this chapter includes stainless steel plate, wind pipe, tuyere, flange, hanging support bracket production and installation, a total of four sections, 9 items.Six, wind pipe fittings including the fabrication and installation project, but does not include the flange and the hanging bracket and the hanging bracket; flange according to this chapter separately calculated the corresponding project.- fixed number: 9-527, 9-528The tenth chapter aluminum ventilation pipes and parts installationFirst, this chapter includes aluminum circular duct, rectangular duct, round cowl, flange manufacture and installation, a total of four 20 items.Four, wind pipe production and installation projects include pipe fittings, but not including flanges and hanging support bracket; flange production and installation in accordance with the corresponding items in this chapter.

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.
