Pipes with rubber linings are essential components in the transport of many types of solutions, chemicals, and liquids, especially when those liquids are corrosive or abrasive. Due to this fact, the materials used in the lining are generally tested for their resistance to abrasion.
How Rubber Linings Are Added to Pipes
The process of creating a rubber lined pipe begins with the creation of the pipe itself. Next, experts inspect the quality of the welding together of any assembled pieces. The surface, or substrate, of the pipe is prepared to accept the lining, generally with a blasting process. An adhesive is applied that will hold the rubber tubing in place, and the tube is threaded into the pipe. At this point, the lining is cured, usually with a vulcanization process. Finally, the lining is tested and inspected to determine whether it meets quality standards. If the pipe is going to be painted, the unlined surfaces are blasted to prepare them to accept the paint. The pipe is then inspected a final time, and the process is complete.
The Versatility of Rubber Linings
Although there are multiple steps in the creation of a rubber lined pipe, the process is fairly straightforward and can be completed on pipes of many sizes. For instance, pipes with a diameter as narrow as 1 ½ inches are routinely lined. The rubber lining can be applied to many types of pipes, including aluminum, brass, carbon steel, cast iron, copper, and stainless steel. Non-metallic surfaces, such as fiberglass, can also accept rubber lining.
Advantages to Using Rubber for Linings
There are advantages to using rubber lined piping systems. These include protection for the pipes from corrosion and abrasion, as well as insulation against noise, vibrations, electricity, and thermal exposures. In addition to these operational benefits, the rubber lining can be removed and replaced for affordable upgrades and maintenance. This is useful for keeping costs down and efficiency up.
