Welded vs. Mechanical Joints for Rubber-Lined Pipe
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.
