Built with the purpose to reduce frictional drag while being used in deviated holes and provide almost 100% stand-off (concentricity) when run in a cased hole, Sawan�s Hinged Non Weld Positive Centralizers are uniquely designed with flat bottom U profile of different depths. The advantage of this design is that they permit maximum fluid passage and also eliminates weak (brittle) spots.
The end collars and the flat U profile are rigidly connected with self-locking action which provides firm and positive hold. This feature also helps in convenient, economic and compact packaging of the product, thus reducing the overall shipping and storage cost. The centralizers are also provided with Iron Phosphate and powder coating to prevent it from rust.
