External Line-up Clamps (ELC)
An external line-up clamp (ELC) is placed over the joint of two pipes and exerts mechanical force on both pipe ends to minimise edge offset.
The ELC is designed as a double ring with adjustable centring bridges and can be opened for easier handling. The mechanical force for the centring process is supplied by a hydraulic cylinder which exerts a pressure of up to 5 t via a hand lever.
Alternatively, a 10 t cylinder with foot pump can be supplied.
Vietz external pipe centring systems are available in medium-duty and heavy-duty versions. In the medium-duty version, the double ring is made of round pipe whilst in the heavy version, flat material is used.
The centring bridges are each shaped in such a way that a welding of the root layers of up to 90 % is possible.
