CLEANWELL® – VAM® Dope-free Coating
CLEANWELL® is a non-polluting, multi-function coating replacing both storage and running compounds applied on the surface of VAM® connections. It is designed to provide exceptional anti-corrosion and lubrication properties.
Dope-free coating solution
Providing increased performance
CLEANWELL® integrates a multi-layer dry coating that combines anti-corrosion and lubricant properties. It protects tubing and casing connections against potential problems such as corrosion, and, for more critical materials such as chromium or high alloy grades, it prevents galling wear caused by friction during make-up.
CLEANWELL® connections greatly reduce back-out and reject rates during operation. The result: less production downtime and higher operational efficiency that keep cost overruns to a minimum. In fact, CLEANWELL® generates significant cost savings over the lifecycle of the pipes.
State-of-the-art technology
Vallourec’s CLEANWELL® solution is based on a multi-layer system featuring a dry engineered lubricant film applied in the mill on premium OCTG connections as an alternative to storage and running dopes, demanding less manual operation on the jobsite.
- A metal-based plating layer protects against corrosion and galling
- A thermoset topcoat offers dry lubrication to ensure extreme repeatability and stability during make-up, plus extra anti-corrosion benefits
CLEANWELL® has been qualified according to the industry’s most demanding protocols, including API RP5 C5:2017 CAL-IV and ISO13679:2019 CAL-IV.
