Description:
"Siberian Metalware Plant" manufactures weld neck flanges according to GOST 33259-2015, from DN15 to DN1400 with an operating pressure of up to 250 kgf/cm2. Any design is possible and for various types of gaskets, we use different grades of steel for production. In addition, we are ready to fulfill additional customer requirements, providing the necessary dimensions for the pipe. We manufacture non-standard products according to your drawings. Mechanical processing of weld neck flanges is carried out on CNC machines, which ensures increased requirements for surface roughness. The flange connection is reliable and ensures tightness when working on pipelines with high pressure. These products are quite simple and quick to install when installing pipelines in any conditions. The application temperature of the products is determined by the grade of steel from which they are made.
Overview:
Advantages of collar flanges
- allow you to organize a connection break without cutting pipes in cases where it is necessary to dismantle part of the pipeline;
- This flange can be welded to the joint of a large pipe, unlike a flat flange, which is put on the pipe and welded around the perimeter.
Flaws
- periodic tightening of the bolted connection is required;
- impressive size and weight.
