Flange

Flowsys manufactures Stainless Steel Flanges of different shapes & sizes & with different specifications as per the customer’s requirement in various material A182 Gr 316, A182 Gr 304, etc….
Our flanges division encompasses an integrated manufacturing facilities which manufactures all types of flanges in various specifications like ASTM/ASME/ANSI, EN, DIN, etc in various class of pressure rating.
We produce flanges in the size range from 1/2″ to 24″. Flowsys has an established & stringent quality system in accordance with various specific requirements & applications.

Types of Flanges – Our manufacturing facilities is well equipped to manufacture various types of flanges namely:

Blind Flange

Blind flange is round plate which has all the relevant boltholes but no centre hole & because of this feature this flange is used to close off the ends of a piping systems & pressure vessel.

Weld Neck Flange

Weld Neck Flanges have a long tapered hub & are often used for high pressure applications. These flanges are designed to be joined to a Piping system by Butt Welding. The Neck, or Hub transmits stresses to the Pipe, reducing stress concentrations at the base of Flange. The gradual transition of thickness from the base of Hub to the wall thickness at Butt Weld, provides important reinforcement of the Flange. The bore of Flange matches the bore of Pipe, reducing turbulence & erosion. These flanges are ideal for extreme fluctuations of temperature & in environments where there may be high temperature.

Slip-On - Flange

Slip On Flanges are easily fitted & welded into different pipes. Slip on pipe Flange is slipped over the Pipe & then welded both inside & outside to provide sufficient strength & prevent leakage. These flanges are ideal for lower pressure applications. This Flange is used in preference to Weld Necks by many users because of its lower cost & the fact that less accuracy is required when cutting pipe to length

Threaded Flange

Threaded flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads. These flanges are ideal for relatively low pressure piping systems.
Threaded flanges are used with pipes that have external threads.
The benefit of these pipe flanges is that it can be attached without welding.

Lap Joint Flange

Lap Joint Flanges slide over the pipe & are most commonly used with Stub End Fittings. A pipe is typically welded to the Stub End & the Lap Joint pipe flange is free to rotate around the stub end. Lap Joint pipe flanges are often used for applications that require frequent dismantling. Threaded pipe flanges are often used for small diameter, high pressure requirements.

Orifice Flange

Orifice Flanges are used instead of standard pipe flanges when an orifice plate or flow nozzle must be installed. Pairs of pressure tappings are machined into the orifice flange, making seperate orifice carriers or tappings in the pipe wall necessary.
