Carbon steel EN1092-1 flange

Hebei Jimeng Highstrength Flange-Tubes Group Co., LTD., specializing in the production of flat welding flange, flat welding flange is a kind of disc parts, is most common in the pipeline engineering, the flange is used in pairs.In pipeline engineering, the flange is mainly used for pipe connection.In need of connecting pipes and all kinds of installation of a flange, the low pressure pipe flange can use silk, the use of more than 4 kg pressure welding flange.
The main effect of flat welding flange is:
1, the pipeline of pipeline connection and keep a good sealing performance;
2, if a certain period of line problems, easy on the replacement of a section of pipeline;
3, line failure, facilitate open test.
Flat welding flange: suitable for nominal pressure of not more than 2.5 MPa steel pipe connection. Flat welding flange sealing surface can be made into smooth type, concave and convex type and mortise type 3 kinds.The characteristics of flat welding flange: flat welding flange not only saves space, reduce the weight, more important is to ensure that the joint parts will not leak, has good sealing performance.Compact flange size is reduced, was due to the decrease of the diameter of the seal, it will reduce the sealing surface of cross section.Second, the flange gasket has been replaced by sealing ring, to ensure that the sealing face sealing surface matching.
Flat welding flange threaded connection (screwed) flange and welding flange.Low pressure small diameter wire connect flange, high pressure and low pressure of large diameter used welding flange, the thickness of the flange and the connection of different pressure bolt diameter and the number is different.According to the different levels of pressure, flange gasket also have different material, from the low pressure asbestos pad, high-pressure asbestos pad to metal pads.Flange connection is convenient to use, can withstand greater pressure.
