Large Diameter Flanges

The large diameter flanges are used to connect or to block off two very large diameters sized pipes.

Large Diameter flanges

We stock large diameter (18” – 42”) SLIP-ON, Lap Joint, Weld Neck, and Blind Flanges in SA105N, in class 150 and 300, and can also source a variety of sizes and classes for longer lead times, from 12” to 60”.

A Large Diameter flange is a metal ring that is used to connect valves, pipes, pumps and other equipment that is necessary to form pipelines. The Large Diameter flange also allows people to have easy inspection, rapid modification, and easy and quick access to clean the pipes.

Large Diameter Flanges Finished

Natural, Nickel Plated, Electro Polished Plated or any coating as per customer specification.

Any kind of special die casting sand gravity die lost wax shell moulding castings and cast parts casting produced to user specifications. We can be more competitive than Chinese castings and cast parts made in China Taiwan Asia Korea as traditional Indian expertise in Brass castings and Brass casting is superior and Indian Carbon Steel foundry / foundries are more competitive than other S.S. Carbon Steel foundries.

What Materials Are Flanges Made From?

The most typical material used for making large diameter flanges is carbon steel that has been forged carefully and which surfaces have been machined.
The flanges are made in multiple ways. Some have lips, while others do not. Nearly every type of flange has a seal attached to it in order to preclude any type of leaks from the pipeline.

Large Diameter Flanges Types

Large Diameter Flanges are corrosion resistant and have a wide variety of uses. We carry variety of threaded flanges, weld neck flanges and slip on flanges and of course we can can custom build Large Diameter Flanges to your specifications.

The A350 LF2 Line is often referred to as Carbon Steel Low Temp Fittings or Flanges

Large Diameter Flanges Simple to Fit
Large Diameter Flanges Simple to fit

Large Diameter Flanges are an integral part of the pipeline system.

1 Simple to Fit

Simple installation in any weather and trench conditions,even underwater!

2 Long Life Expectancy

Elastomeric sealing gaskets are designed to have at least a 50 year lifespan

3 Corrosion Protection

Metal components are coated with Rilsan Nylon 11 which is WRAS approved for use with potable water. The nuts and bolts are Sheraplex coated to WIS 4-52-03, offering long term protection against corrosion, impact and abrasion to ensure continued reliable protection to corrosion, impact and abrasion and therefore ensures continued reliable performance.

Bolting two different flanges together with a gasket place between the two flanges in order to make a seal in the pipe joint creates flanged joints.

We carry a large inventory of Large Diameter Flanges in many types and sizes.

Spectacle Blind Flange
Spectacle Blind Flange
Spectacle Blind Flange consist of a connected ring and a plate.

Screwed Flanges
This flange is referred to as either threaded or screwed.

Weldoflange, Nipoflange
Anchor flange
An anchor flange is a device installed on a pipeline to combat axial movement.

Orifice Weld Neck Flanges
Orifice Flanges
Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings.
Long Weld Neck Flange
Reducing Flange
Reducing Flange is used on projects that require the fitting together of different sized pipes.
Expander Flange
Expander Flange
Expander Flange is using a separate reducer-welding neck flange combination.
Anchor flange
Weldoflange / Nipoflange
Weldoflange / Nipoflange is a combination of a Welding Neck flange and a supposedly Weldolet or Nipolet.
