V-band couplings: helpful beyond imagination

Among the top turbo clamp distributors in India, Jolly Clamps have a great reputation. As a matter of fact, Jolly Clamps have been known for being the best no hub coupling manufacturers and distributors for lined worm drive clamps.
A yet another product that Jolly Clamps have been well known for, is V-band couplings. Jolly clamps have widespread fame across the national market as V-band coupling distributors.

V-band couplings are used widely for the purpose of joining component sections, tubes, pipes, etc. from end to end. They are of great use as they help the pipes or tubes carry load while they are conducting the fluids. V-band couplings have two major components: a t-bolt clamp and v-retainer over the flanges. So, in order to join the components or the tubes, the two ends are placed between the v-retainer and the t-bolt clamp is tightened which combine to create a wedging action and put a compressive force on the flanges.
The mechanical advantage of a V-retainer is inversely proportional to the v angle; the greater the v angle, the lesser the mechanical advantage and the lesser the v angle the greater the mechanical advantage. Ideally the retainer type that is used is the all-formed retainer. However in case of high pressure systems, a machined retainer is used.
There are further, 4 retainer segments used:
One segment retainer, which has limited uses because of its rigidity.
Two segment retainer made of two segments and are cost effective to manufacture. They are effective for tube diameters over 5 inches. They can be used for heavy duty applications too.
Three segment retainers are made of three segments and provide double hinging actions. Their usage is limited to conventional latched only.
Four segment retainers are used for relatively larger diameters where there is expected to be a lot of hinging action. They can be used with both single and double latches.
