Flange Adaptors

We are engaged in manufacturing and exporting an enormous array of flange adaptors which is meticulously designed and fabricated by our in-house team of quality controllers. The finest quality flange adapters are specially fabricated by industrial experts adapting innovative production process that assisted us to provide the complete satisfaction to our most valued customers. Our comprehensive range of flange adapters are complying with industrial quality standards so that we have carved a niche for ourselves. As a reputed flange adaptors manufacturer and exporter, we have gained a lot of admiration from the worldwide customers and most acknowledged due to its efficiency, durability, reliability of our most usable flange adaptors. We are rewarded by the repeated orders of our esteemed customers because of our unmatched quality products.

Flange adaptors allow flanged fittings and valves/meters/pumps to be installed in plain ended pipe systems.

This flange adaptor offers the same advantages as the LEELA sleeve pipe couplings — and more. The flange adaptor is the ideal solution for connecting valves and pumps in your piping system, absorbing damaging stresses that are transmitted along the pipeline and eliminating costly downtime for repair. Also the flange adaptors can be installed quickly and easily.

Adaptors are supplied standard flat faced (Fig. A). Raised face flanges are supplied upon request. Flange drilling can be made according to all international flange specifications.

STANDARD FLANGE ADAPTORS

These are available in three basic styles with different sleeve designs

A. Straight Sleeve

The standard flange adaptor has a straight sleeve and a flat face. The PCD for the flange drilling varies according to the pressure rating of the flange as well as it’s nominal size.

B. Expanded Sleeve

Generally for use with very thick walled pipe such as asbestos cemen or concrete. The expanded sleeve can also be used when the nominal sizes of the flange and the pipe are different ( e.g. connecting 250NB/12" nom. pipe to a 200NB/8” nom. valve)

C. Tapped flange

As an alternative to the expanded sleeve, mismatched components may be joined using a tapped flange (Fig. D ). It has a straight sleeve giving a greater pipe insertion length, especially important when the system is subject to excessive movement or temperature fluctuations. Studs, instead of bolts, are used to make the connection to the mating flange. Dimensions B on Fig.D varies with the flange thickness‘t’, relative to the tapping diameter.
