The flanges of loose sleeve are used to cover the flanges on the pipe end with flanges such as flanges and steel rings. The flanges can move on the pipe end. A steel ring or flanging is a sealing surface, and a flange is used to compress them. Thus it can be seen that the loose flange does not contact with the medium because it is blocked by steel ring or flanging.
Loose sleeve flange is suitable for connecting and corrosion-resistant pipeline of stainless steel, aluminum and other non-ferrous metal and stainless acid-proof steel container.
Slip-on flange, flange can be activity is usually necessary in water supply and drainage (most common) on the slip joint fittings, factory factory will each have a piece of flange on both ends of the expansion joints, directly with the engineering of piping, equipment, bolting.
Features of flat welded flanges: flat welded flanges not only save space and reduce weight, but also ensure the joint parts will not leak out, with good sealing performance.The compact flange size is reduced by reducing the diameter of the sealing element, which will reduce the section of the sealing surface.Second, the flange gasket has been replaced by a sealing ring to ensure that the seal is matched to the sealing surface.In this way, only minimal pressure is required to keep the cover tight.As the pressure required to reduce, the size of the bolt and the required quantity can be reduced accordingly, so the final design out a small volume and light weight (70% ~ 80% reduction in weight than traditional flange) of new products. Therefore, flat-welded flanges are a kind of high quality flanges, which reduce the quality and space, and play an important role in industrial use.
High pressure flange: used for pipe or equipment connections with pressure over 10MPa.At present, it mainly includes traditional high - pressure flange and high - pressure self - tightening flange.
Traditional high pressure flange: is the use of gasket (ellipse gasket, octagon gasket, lens gasket, etc.) of plastic deformation to achieve sealing effect, connection pipe, pipe and pipe connected parts, flange hole, stud makes the flange closely linked.
Welded flange is a pipe fitting, refers to with a neck and a circular tube transition and pipe butt welding flange. Butt welding flange is not easy to deformation, good sealing, wide application, have corresponding rigid and elastic demand and reasonable butt thinning transition, joint good distance away from the joint face the faying surface from welding deformation temperature.
Scope of application: Butt welding flange is not easy to deformation, good sealing, wide application, have corresponding rigid and elastic demand and reasonable butt thinning transition, joint good distance away from the joint face the faying surface from welding deformation temperature, it take more complex syndromes beep form structure, suitable for pressure or temperature fluctuations of pipeline or high temperature, high pressure and low temperature pipes, commonly used in PN is greater than 2.5 MPa pipe and valve connection; Also used to transport is expensive, inflammable, explosive medium on the pipeline.
Galvanized flanges flanges is a kind of good corrosion resistance, can be produced in flange forming rust removal after into the liquid zinc melting around 500 ℃, the zinc layer adhered on the surface of the steel members, which have the purpose of corrosion protection.
Flange is also called Flange or Flange. A flange is a part that connects a pipe to a pipe and connects it to its end. There are holes in the flange, and bolts tie the two flanges together.The flanges are gasketed. Flange split-threaded (threaded) flange and welded flange.
