Various types of centring devices are used to minimise edge offset when welding pipes. The devices also facilitate adjusting the gap between pipes. Depending on the type of device, it centres the pipes from the inside or outside.
Vietz GmbH supplies internal pneumatic line-up clamps, external line-up clamps with hydraulic cylinders in various versions, but also, for example, centring chains. Please do not hesitate to contact us.
The selection of a suitable centring device depends on the welding process, but also on local conditions, such as the presence of compressed air for the supply of a pneumatic internal centring. Vietz therefore supplies the Arcotrac type tracked paywelders with an optional compressor package.
Vietz external pipe centring systems are available in medium-duty and heavy-duty versions.
Our internal pneumatic line-up clamps are designed for up to two pipe sizes and can be adjusted for all wall thicknesses in accordance with API5L.
