Welded vs. Mechanical Joints for Rubber-Lined Pipe
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 #3 - Ideal for Higher Pressure Pipelines
Unlike mechanical joints, welded joints have pressure ratings equal to that of the pipe wall. This prevents the need for heavy duty flanges for high-pressure pipelines. The cost of thick machined flanges and bolting is exorbitant compared to welded joints. While low pressure pipelines can realize significant savings with Joint Lock™, the construction cost of high-pressure pipelines can be reduced by more than 30%.
In addition, installation contractors and maintenance personnel are very familiar with the difficulties of obtaining a proper seal between two rubber lined surfaces when high pressure is involved. Retightening most joints after charging the line is required and keeping the joints leak-free is an ongoing maintenance concern.
