Oil Patch Bits: Polyguard offers new pipeline protection

As reported on the Australian Pipeliner Website Dec. 16, the U.S-based Polyguard Products has been a manufacturer of buried pipeline coatings since 1950 and is now offering the RD-6 coating system to the Australasian market.

One of the company’s most successful products has been the RD-6 buried pipeline coating system, which was launched in 1987. The RD-6 system has been used by a large sector of the United States oil and gas industry for over 25 years.

The product was initially used by customers for pipeline maintenance and rehabilitation; however, it is now also used widely for protection of girth welds on all new pipelines such as those installed throughout the massive shale oil and shale gas fields. Millions of square meters of pipeline have been coated throughout the world using the RD-6 system.

As a superior and differentiated tape system, the RD-6 offers excellent soil stress resistance, installs faster than most other coatings, is proven to be non-shielding to cathodic protection currents in case of disbondment and requires no cure.

RD-6 is a single-layer system, applied with a liquid primer. In very harsh applications an optional soil stress-resistant outer wrapping layer is also available. In accordance with the installation specifications the RD-6 is applied with a 25.4 mm overlap. The coating can be applied with or without initial preparation such as sand blasting and as a single-layer coating, and offers substantially higher production rates during application in the field.
