What is swivel ring flange?

The Swivel Ring Flange is of two piece construction consisting of a heavy forged welding hub with a rotating forged ring that serves as a mating flange to a Weld Neck or other flange. It has a Retaining Ring to secure the Welding Hub to hold the Rotating Ring in position.

What is a weld neck flange used for?

Weld neck flanges are used in applications where the conditions are severe and critical. Some of these conditions include high pressure, wide fluctuations in temperature and pressure, high temperature, fluids that are volatile and hazardous, and temperatures in the sub-zero range.

What is the difference between a weld neck flange and a slip on flange?

This is because a slip on style flange will accept a pipe with a fillet weld connection, whereas a weld neck flange will have a reinforced hub at the base and form a weld bevel connection directly to the butt weld end of a pipe. This tapered hub allows for stronger service in a mechanical stress environment.

How does a swivel flange work?

A swivel ring flange has a heavy forged welding hub that is fixed to a forged ring that can be rotated to serve as a mating flange to a weld neck or another flange. In a swivel ring flange, the rotating ring is held on by the welding hub that is in turn secured by a retaining ring.

What is a ring flange?

A Ring type joint flange(RTJ) is a machined metallic ring with a deep groove cut into its face. This groove rests a metal ring which gets compressed when the connecting bolts of the flange are tightened. This compression results in a leak-proof, close-fitting seal on the pipe or connection.

Can we connect slip-on flange to weld neck flange?

Slip-on and weld neck flanges of the same size are generally fully compatible for mating. The slip-on will obviously have a bigger bore diameter as it goes over the pipe rather than being butt welded to it.

What is a raised face weld neck flange?

RFWN Flange (Raised Face Weld neck Flange) are one of the most commonly used flange in the piping industry. They are easy to recognize with their long tapered hub that is matched to the wall thickness (bore) of the pipe.

Can we connect slip on flange to weld neck flange?

Is slip on flange cheaper than weld neck flange?

Although the initial cost of a Slip On Flange is slightly less than a Weld Neck Flange, you have two welds one on the back side and one on the inside of the Flange and the added inspection of the second weld doubling weld and inspection cost.

How does a swivel joint work?

Swivel joints are precision machined components that are used to connect and prevent bends in stationary loading hoses that can reduce flow, tear, or rip, releasing harmful chemicals into the air.

What is a weld flange?

SOCKET-WELD FLANGE The flange comprises a drilled flanged blade with a machined face on one side and, on the other, a female socket into which the pipe is placed. As with the weld neck, these flanges are generally made from forged steel.

What are ring joint flanges used for?

The Ring Type Joint flanges are typically used in high pressure (Class 600 and higher rating) and/or high temperature services above 800°F (427°C). They have grooves cut into their faces which steel ring gaskets.

What is ring joint?

A Ring Type Joint (RTJ) Flange is basically a machined metallic ring having a deep groove cut into its face. Metallic RTJ gaskets sit in the groove to seal the flange pair. When the connecting bolts of the RTJ flanges are tightened, the gasket is compressed and the flange pair creates a leak-proof tight seal.

Do you weld slip on flanges?

SLIP-ON FLANGES This Slip-On Flange is often chosen over Welding Neck Flanges because of its lower initial cost and is widely used because it requires less accuracy in cutting pipe to length and permits alignment of bolt hols and squaring of flange faces with less difficulty.

Do you weld the inside of a slip on flange?

How do slip-on flanges work? Slip-on flanges must be slid into the pipe before welding. In this case it is a double weld, both inside and outside, thus providing the durability they need to avoid leaks. Their pressure resistance is rated at approximately 2/3 of that of a welding neck flange.

What is the difference between flat face and raised face flange?

The difference between a raised face and a flat face flange is that the raised face has a raised area that surrounds the pipe bore and the flat face flange doesn’t. These are two of the most commonly used types of flange faces.

What are swivel fittings used for?

Swivel-type fittings are designed to allow the coupling and hose connection to rotate, which prevents twisting, kinking and excessive bending. That can extend hose life and reduce maintenance needs.

What is a swivel ring flange?

The SWIVEL RING FLANGE is of two piece construction consisting of a heavy forged welding hub with a rotating forged ring that serves as a mating flange to a Weld Neck or other flange. It has a Retaining Ring to secure the Welding Hub to hold the Rotating Ring in position.

What is a retaining ring on a flange?

It has a Retaining Ring to secure the Welding Hub to hold the Rotating Ring in position. These versatile flanges are utilized in many applications and are used extensively in offshore piping where they solve the issues associated with the alignment of bolt holes during subsea flange installation.

How does the outer ring flange assembly work?

The outer ring flange assembly is held in position by a retainer ring that freely rotates around the inner weld-neck hub for quickly positioning the bolt holes of the two joining flanges.

What is a subsea flange and how is it used?

These versatile flanges are utilized in many applications and are used extensively in offshore piping where they solve the issues associated with the alignment of bolt holes during subsea flange installation.
