The JIS B2220 5K Slip on Hubbed Flange is mostly used for gas valves, natural gas pipelines, etc. Because there is a short neck to improve the flange stiffness and improve the bearing capacity. It is suitable for places with high flammability, explosion, corrosion and toxicity. It is also suitable for use in piping systems where pressure levels are low and pressure fluctuations, vibrations and oscillations are not severe. The sealing surface with neck flat welding flange can be used with protruding surface, concave surface and groove surface. It is a connecting component used in many industrial pipes.
The flat welded flange with neck not only saves space, reduces weight, but more importantly ensures that the joint is not leaked and has good sealing performance. Its reduced size is due to the reduced diameter of the seal which will reduce the cross-section of the sealing surface.
1. The JIS B2220 5K Slip on Hubbed Flange is made of exquisite stainless steel, which makes the product more durable. The product's appearance is bright and shiny, which can extend its service life.
2. It uses strict process technology. When casting products, the control is strictly controlled according to the standard, so that the bearing pressure under the same working conditions is improved.
3. The surface of the flange is precision cast without obvious defects and burrs, and the sealing performance of the product is good.
We have stainless steel flanges which are forging, and skilled craftsmanship. We can produce small and large diameter flanges and non-standard flanges, sight glasses, tube sheets, manholes, hand holes and other products.
