Advantage #4: Welded vs. Mechanical Joints for Rubber-Lined Pipe

Joint Lock Ring video demonstration

Welded joints have always been the standard connection method for unlined pipe due to their strength and ease of construction. Now with Joint Lock Ring™ technology, welded joints are available for rubber and polyurethane lined pipe as well.

Advantage #4 - Lower Cost than Flanged Connections

The Joint Lock Ring™ system allows for standard full-penetration welds. Welded joints are less costly than flanged connections at every step ─ no flange and bolting costs; shop fabrication and rubber lining costs are significantly lower; installation is quicker because bolt re-tightening and field fit-up time are reduced or eliminated. And, no joint maintenance required!

Reduce the cost of pipelines by up to 30% with Joint Lock.
