Flange adapters are available in straight and 30 degree elbow Storz forgings. All adapters are hard coat anodized for corrosion resistance. Carbon steel flange is stripped and cleaned of any manufacturing oils or dirt providing a good base for primer adhesion. A Zinc rich primer coat is applied that seals the entire carbon steel flange.
Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip on and Blind Flange. StandardsANSI, MSS, API, AWWA, DIN, JIS, BS and GB.
ANSI B16.5 threaded flange . Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications. They are the special type of pipe flanges which can be attached to the pipe without welding. Threaded flanges are threaded in the bore which match an external thread on the pipe.
Blind Flanges may be made with the same hub as that used for Slip on Flanges or without hub. The gasket surface and backside (bearing surface for bolting) are made parallel within 1 degree. To accomplish parallelism, spot facing is carried out according to MSS SP 9, without reducing thickness (C).
Slip on flanges cost less than welding neck flanges, and require less accurate pipe cutting, but their strength is approximately 2/3 of weldneck flanges under internal pressure, and they have approximately 1/3 the fatigue life of weldneck flanges. Slip on flanges shall be welded at the front and back of the hub,
Jan 08, 2019 · The integrity of the flange connection is critical to the delivery of fluid piping systems. Whether it is a piping system that transports chemical media (such as hydrocarbons) or a water supply line, flange connection leakage can cause serious environmental and economic impacts, and may even pose a huge safety hazard.
Sep 25, 2018 · Carbon Steel Blind Flange Carbon steel has the largest usage in the world, and common in Pipe Fittings. It is economic and practical, it has great strength and hardiness. Usually we make the flange surface with anti rust oil and black primer.
