Welded vs. Mechanical Joints for Rubber-Lined Pipe

No Bolt Tightening, No Damage

Welded joints eliminate the potential for sealing surface damage that can cause leakage and significantly delay projects.

The most common problem with mechanical connections for rubber-lined pipe is leakage, which often comes from rubber sealing surface damage. The rubber on the exposed ends of pipe can be easily damaged during handling, transport, and installation. Overtightening is another common problem that displaces rubber and creates uneven sealing surfaces. Repairing sealing surfaces is difficult, particularly in the field.

Joint Lock eliminates these headaches.

When the welded joint is completed, it's done. There's no bolt retightening nor worries about rubber damage. In summary, installation is easier and less can go wrong with welded joints than mechanical joints.
