EN1092-1 type11 is WN flange,
Butt welding flange is two large diameter pipe connection device, usually two flange and number of the bolt, its plastic strength is low, after adding suitable amount of carbon becomes hard, plastic lower strength enhanced.Connection it may need to bear very high tensile, compression, torsion and shear strength.Butt welding flange conveniently, manufacture simple, low cost, widely used, but with poor rigidity, therefore shall not be used for supply and demand, flammable, explosive and high vacuum degree requirements of the chemical process piping systems and height, extremely dangerous situations.Sealing surface type plane and surface.Butt welding flange welding electrode consumption is much, can not stand high temperature, high pressure, repeated bending and temperature fluctuations.
We are specializing in the production of welded carbon steel flanges, flat welding flange, carbon steel flanges, Japanese standard flange, flange of products such as loose flange, my company's products are highly trusted by customers.Today with everyone know about the high pressure flange generally what are the features:
High pressure flange of the steel gate valve generally applicable to the nominal pressure PN10.0 ~ 25.0 Mpa, the working temperature - 29 ℃ ~ 600 ℃ oil, chemical, thermal power plant under various working conditions such as the pipeline, cut off or connect medium. High pressure flange connection steel gate valve generally applicable medium: water, oil, steam, etc. Mode of operation are: manual, gear drive, electric, etc.
High pressure flange connection and the characteristic of steel gate valve products
1, gate using wedge type flexible disc structure, large diameter set the rolling bearing, friction small, easy opening and closing.
2, high pressure flange gate valve stem by conditioning and surface nitriding treatment, has the good corrosion resistance and abrasion resistance.
3, high-pressure flange connection steel gate valves conform to the requirements of domestic and international advanced standard, reliable sealing, excellent performance, beautiful appearance.
4, disc and seat sealing surface with iron base alloy welding or department too stand (stellite) cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, corrosion resistance, good abrasion resistance, long service life.
High pressure flange not only saves space, but also reduced 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.Thus, in order to close cover only need a small pressure.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.So high pressure flange is a more excellent flange products, reduced the quality and space, and played an important role for industrial purposes.
