FlexLock® Flange Adaptors

CT Series

The FlexLock system provides a self-anchoring method of joining ductile iron or steel pipes and offers a cost effective, quick and simple alternative to traditional anchoring systems such as site welding, harnessing or thrust blocks.
Extensive range is available in sizes DN50 - DN300

Cost effective – FlexLock can provide significant cost savings compared to non-locking couplings with a harnessing system.

Restrains pressure thrusts without thrust blocks at bends.

Convert cut lengths of pipe into flanged pipes – allows use of pipe offcuts.

For gas applications a working pressure of 6 bar can be achieved.

Flange Adaptor Body Options:
Ductile Iron to BS EN 1563 EN-GJS-450-10
Mild Steel to: BS EN 10025: Grade S275
Gasket: EPDM compound Grade E to BS EN 681-1
Nitrile compound Grade ‘G’ to BS EN 682-1

FlexLock permits angular deflection between pipes, allowing for normal pipeline movement such as ground settlement. Long radius curves can also be accommodated, reducing the need for special fittings. FlexLock couplings allow for a total angular deflection of ±6° (±3° for flange adaptors).

The ability to provide angular deflection in ANY plane is a particular advantage – a harness assembly can provide angular deflection only in ONE plane.
