British Standard Flanges
BS4504 flanges are corrosion and abrasion resistant and have a longer service life.
Standard: BS4504
Type:Plate flange, Threaded, Irrigation,Blind, Lap Joint flange
Flanges Introduction:
A flange is a approach of connecting pipes, valves, pumps and other gear to form a pipework system. It additionally provides handy access for cleaning, inspection or modification. Flanges are typically welded or crewed into such systems and then joined with bolts.

Flange types:
Weld Neck This flange is circumferntially welded into the gadget at its neck which capacity that the integrity of the butt welded location can be without difficulty examined by means of radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inner the pipeline. The weld neck is consequently favoured in vital applications. | |
Slip On This flange is slipped over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications. | |
Blind This flange is used to blank off pipelines, valves and pumps, it can also be used as an inspection cover. It is sometimes referred to as a blanking flange. | |
Socket Weld This flange is counter bored to take delivery of the pipe earlier than being fillet welded. The bore of the pipe and flange are each the identical consequently giving appropriate float characteristics. | |
Threaded This flange is referred to as either threaded or screwed. It is used to connect other threaded components in low pressure, non-critical applications. No welding is required. | |
Lap joint This flange is used with both a stub give up or taft which is butt welded to the pipe with the flange free at the back of it. This potential the stub give up or taft usually makes the face. The lap joint is favoured in low strain functions due to the fact it is without difficulty assembled and aligned. To minimize price this flanges can be furnished barring a hub and/or in treated, lined carbon steel. | |
Ring Type Joint This is a method of ensuring leak proof flange connection and 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 Nexk, slip-on and blind flanges. |
