E-joint
George Green is now very proud to announce that after much research, development and investment the organisation has over the last year or so been manufacturing and supplying pipes and fittings with the bona fide E-joint. This joint is produced in house at our Keighley manufacturing site and is supplied over our diameter range. These pipes and fittings are now installed on a number of projects around the UK. We have been able to do this by committing and investing time and money in the most up to date computerised equipment and professionally trained operatives ensure we produce a high-quality product.
Beneficially for the Installer saving time, and remedial costs the E-joint is a mechanism that allows the Steel Pipe/Fitting to be welded together externally only and with the major advantage that the welding process does not damage the internal lining thus mitigating the need to enter the pipe, irrespective of the pipe being man entry or not. This is achieved by the creation of an air chamber at the spigot end of the pipe or fitting, This is achieved by an internal sleeve being welded into place using our duel headed welding console.
In addition, George Green has made further investment to enable them to have the ability to expand a pipe end to form a socket to high tolerances. This is achieved using a computer controlled hydraulic expansion machine. All functions of the expander equipment are designed to be controlled manually on the operator control panel, furthermore they can be run automatically under the control of the operator.
On site the socket end then works in tandem with the spigot/E-joint end, so that the male spigot end is entered into the female socket end, and a field weld is performed on the external of the pipe joint only.
