The CLS WedgeRing® adaptive system is now fully proven through utilization in aggressively-corrosive injection and production systems that require premium GRE-lined casing and tubing. The WedgeRing® system enables the joining of GRE-lined premium tubing and casing without compromising protection across the connection. 

WedgeRing® is affordable, versatile and innovative and is provided exclusively by Composite Lining Systems. Our goal is to create "bulletproof" tubular solutions for corrosive disposal, storage and production systems using tubular products to 7-inches in diameter. CLS customers are using the patented WedgeRing® adapter to connect millions of feet of premium tubing and casing, installed into corrosive service around the world.
