Prefabrication process

Prefabrication begins with the accurate cutting of the pipes to the required length. The pipes are then bent with L&A Mach-Techs cold bending machines. Non-standard and large diameter pipes are bent using induction bending.

After bending, the pipe ends are prepared for flare flanges (flared) or retain rings (grooved). If needed, the modules can also be pressure tested before being dispatched from the workshop. Cleaning and external painting is done in accordance with the customers requirements. Proper packing and protection ensures the quality of the delivered piping modules.

The use of prefabricated piping modules (pipe spools) ensures the highest possible quality as well as an easy and fast installation. In order to further speed up the installation smaller bore pipes, typically between 16 and 42 mm, can be assembled in groups directly onto support frames.
