Lap Joint /Van Stone Flange

· Lap joint flanges are always used with either a stub end or Taft which is butt welded to the pipe with the flange lose behind it.

· This means the stub end or Taft always makes the face.

· A lap joint is used in low-pressure applications because it is easily assembled and aligned.

· To reduce costs, these flanges are supplied without a hub.

· If stub and flange are of the same material, they will be more expensive than a welding neck flange.

· Economical for the different material of stub and flange.

Socket Welding Ring Flange

 

Socket weld ring flanges are counter-bored to accept the pipe before being fillet welded.

The bore of the pipe and flange are both the same to provide good flow characteristics.

· Easier alignment of smaller lines than Butt weld fittings

· Tacking procedure is not necessary, therefore reducing welding time.

· No chance of leakage

Spectacle blind

A spectacle blind is a safety device used to isolate a section of the line.

It is a piece of equipment used when the line or equipment needs to be inspected or removed from service.

It is different than a valve in that the blind is a permanent or long-term isolation device.

Long Weld Neck Flanges are distinguished from other flanges by their long tapered hub and gentle transition of thickness in the region of the butt weld, joining them to the pipe. This type of long welding neck flange is preferred for application in the piping system which involves high pressure and elevated temperature. We specialize in manufacturing stainless steel long weld neck flanges in both alloy and non-alloy materials based upon the application requirement of the clients.

Ring Type Joint Flanges

Ring type joint flanges are used to ensure a 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 Flanges.

Welding Neck Flange

Weld neck flanges are circumferentially welded at the neck where the integrity of the butt welded area can be easily examined by radiography.

The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline.

The weld neck is therefore durable for critical applications.

Suitable where

· extreme temperature,

· shear,

· impact and vibrational stress apply

Regular - Generally used in piping sections.

Long - Used in vessels, equipment nozzle, rarely used in the piping system.

Slip-On Ring Flange

Slip-on flanges are fitted over the pipe and then fillet welded.

Slip-on flanges are easy to use in fabricated applications.

Internal welds are slightly more subject to corrosion than the Butt Weld Neck Flanges.

Poor resistance to shock and vibration

Cheaper to buy

Costlier to assemble

Strength under internal pressure is just 1/3^RD of that of corresponding WN Flange.

Easier to align than WN Flange.

Threading Flange

Threaded flange are referred to as either threaded or screwed.

They are used to connect other threaded components in low pressure, non-critical applications. No welding is required.

Non-toxic, Environment friendly and cost effective as no welding is involved.

Chances of leakage are comparatively higher, generally not used where leaks cannot be tolerated.

Used in services where regular maintenance is required.

All fittings are threaded internal(Female) with American National Standard Pipe Threads ASME B1.20.1 (NPT) or British Standard Pipe Threads (BSP)

Reducing Flange

Specified by the size of the smaller pipe and outside diameter of the flange to be mate.

Example: RED FLG 4” x 11”

· Should not be used if abrupt transition would create undesirable turbulence as in the case of pumps.
