Welded vs. Mechanical Joints for Rubber-Lined Pipe
Welded joints have always been the preferred connection method for unlined pipe. Now, with Joint Lock Ring™ technology, welded joints are available for rubber and urethane lined pipe.
Advantage #1 – Zero Leakage
Leaks at mechanical joints come from many factors, including thermal expansion, uneven bolt torque, rubber damage, and pipe movement. Pipeline contractors and maintenance personnel who work with rubber lined pipe are very familiar with the challenges of getting a proper seal with mechanical joints.
Some companies have moved away from mechanical joints by using exotic alloys and HDPE that are resistant to the abrasion and chemicals. Joint Lock Ring™ technology can tilt the scale toward the use of rubber lined carbon steel pipe, which is stronger and more abrasion-resistant than HDPE, and less expensive than exotic alloys.
Joint Lock eliminates all leakage worries and allows for simple full penetration welds. After installation, just charge the line and walk away knowing the line will remain leak-free.
