Flat welding connection characteristics of carbon steel flange

Flange common flat welding flange and butt weld ends flanges, flat welding flange of the poor rigidity, suitable for pressure p 4 mpa occasions or less; Butt welding flange is also called the high neck flange, large rigidity, suitable for the occasion of high pressure and temperature. And there are three kinds of flange sealing surface model: planar seal face, is suitable for the occasion of pressure is not high, medium non-toxic; Concave-convex sealing surface, suitable for pressure slightly higher occasion; Mortise sealing surface, suitable for flammable, explosive, toxic medium and high pressure situation. Different flange pipe fittings in different fields have good product performance, to adapt to different occasions and space, the effect will be different.

Flange gasket is a kind of can produce plastic deformation, and has certain strength rings made of materials. Most gaskets from non-metallic plate cutting down, or produced by professional factory in accordance with the provisions, the size, the material of asbestos rubber sheet, asbestos board, PE board, etc.; Also useful sheet metal (tin, stainless steel) will be made of asbestos etc. Nonmetal material wrapped metal package cushion; Another with steelskin belt with asbestos tape winding of spiral wound gasket, the user can choose according to their different amount needs to.

Flat welding flange connection method with the simplest connection methods between cast iron pipe and steel pipe. While the blind flange plate can be used to check the mouth open. In addition, flange connection is suitable for the diameter from phi 50-315 - mm pipe connection.

Its characteristics: non rigid connection, can tear open outfit, tensile resistance. Flange connection method is used on low pressure pipeline detachable fittings. Flat welding flange connection may need to bear very high tensile, compression, torsion, shear strength, large flange is a better choice. Commonly used on the pipeline, in that case, the pipeline on both sides of the loose bolts can rotate, can tighten again convenient dismantling the pipe material is carbon steel flange is called carbon steel flange.
