Seamless welded rubber lining pipe
Linings are a premium form of corrosion protection for some of the most severe chemical and abrasive environments. Natural and butyl rubber linings withstand a variety of high-concentration acids and are the optimum choice for high heat and abrasive environments. Additionally, the elasticity of a rubber lining easily accommodates thermal expansion and contraction as well as vibration.
Seamless welded rubber lining pipe main features are as the follows:
1. The chemical properties are stable, and the characteristics of high heat-resistance and anticorrosion are also excellent;
2. The impact resistance is strong due to the outer protective layer of steel;
3. Pipes is connected with flange, and easy to installation
The Company's product solutions enable its customers to address the challenges presented by demanding industrial applications, including:
Mining, transporting and processing abrasive particles of varying sizes,
Transporting and processing corrosive materials with varying chemical properties,
Transporting slurry via pipeline at extreme temperature differences (interior vs. Exterior),
Managing equipment wear performance in light of high velocity transportation,
Reducing work injury from the installation and maintenance of equipment,
Maximizing the speed and effectiveness of all mining, transporting and processing functions,
Minimizing the impact and wear/tear on equipment placed in harsh environments,
Minimizing the replacement or servicing of wearable equipment and
Minimizing the use of costly and hard-to-find skilled labor.
