blind flange specifications : Flat-faced (FF) copper nickel flanges do not have any form of ridge or protrusion on the surface. -

Flat-faced (FF) copper nickel flanges do not have any form of ridge or protrusion on the surface. With these flanges, the gasket has full contact with the entire surface of the copper nickel blind flange.

We counted as one of the privileged manufacturers, stockists, exporters, and suppliers of an admirable range of a Butt weld Fittings in Stainless Steel, Carbon Steel, Alloy Steel, and many more other materials. We are your one-stop solution provider for industrial pipe fittings located in Mumbai, India.

Threaded pipe flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads. Threaded pipe flanges are used with pipes that have external threads. The benefit of these pipe flanges is that it can be attached without welding. Threaded pipe flanges are often used for small diameter, high pressure requirements. Slip on Pipe flanges with a hub have published specifications that range from 1/2″ thru 24″. Hyupshin Flange provides Slip-On pipe flanges in all material grades, specifications and sizes.

Raise face (RF) copper nickel blind flange are those with a section slightly raised above the area with bolt holes. The design allows you to use a range of gasket designs.

Copper nickel blind flanges are common in desalination plants, offshore mining, shipbuilding industries, food processing plants, desalination, water distribution, and power generation plants amongst others.

Our manufacturing process for blind flanges includes an adequate heat treatment and the examination of chemical and mechanical properties. We have CNC machines as well as conventional lathe machines for machining and processing various types of blind flanges.

Our annual sales volume over 70,000 tonnes in India and Worldwide, has won us the dealership and distributorship of renowned seamless (JINDAL, ISMT) and welded steel pipes manufacturing companies across the globe.

(a) For figures 7 (Bevel for wall thickness  from 5 mm to 22 mm), figure 8 (greater than 22 mm) and figure 4 (Straight Hub Welding Flange) in ASME B16.5.

Octal Flange is concentrating on providing different material of steel flanges for industrial company and individuals. We are located in China, equipped with multi-base inventory in south and north of China. We have large in-stock flange material which to complete your urgent requirements at the first time.

In NPS, is designation for nominal flange or flange fittings size. NPS related to nominal diameter, DN in international standards, relations as below:

ASME B16.5 is the most common use standard specification for manufacturing cast and forged steel pipe flange and flanged fittings. 

Weld neck pipe flanges attach to the pipe by welding the pipe to the neck of the pipe flange. The allows for the transfer of stress from the weld neck pipe flanges to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are often used for high pressure applications. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe. Weld Neck Pipe flanges with a hub have published specifications that range from 1/2″ thru 96″. Hyupshin Flange provides Weld Neck pipe flanges in all material grades, specifications and sizes.

The only holes on copper nickel blind flange are for bolts that you will use to secure it to the piping system.

The material of the ring gasket shall comply with ASME B 16.20. The user is responsible for selecting gasket materials that are suitable for operating conditions, can withstand bolt loads, and do not cause cracking.
