Internal coating of pipelines for high-temperature crude oil (80°C)

BIELEFELD, Germany - March 18, 2015 - PRLog -- In China, riser pipes for an oil platform were coated internally with our protection system PROGUARD CN 200. The outstanding physical properties were essential for the choice of our premium product.

PROGUARD CN 200 provides high-grade chemical resistance at elevated operating temperatures, excellent abrasion resistance and an extreme fast curing time with a simple application.

Project: Internal coating of pipelines (riser tubes) for hot crude oil, China

·Customer: CNOOC Ltd., Zhanjiang/China

·Pipeline builder: CNOOC Zhanjiang detect engineering Co. Ltd

·Application of the coating: Guangzhou Wwin petrochemical Technology Co. Ltd

· Coating product: Proguard CN 200

·Completion: May 2014

Technical Data:

Item:  Several riser pipes for oil platform

Length:  approx. 60 m each

Inside pipe diameter: DN 150 – 6 inch

Media: Crude oil, oil water mixture

Oil temperature:  constantly 80°C

First of all, the pipelines were grit blasted according to standard SSPC-SP10 by special pipe interior sandblasting equipment with rotating head.

Our coating product PROGUARD CN 200 was applied in 2 layers, each with a thickness of 500 µm. The application process could be conducted accurately by a specific pipecoater. Due to low viscosity this coating system is sprayable without pre-heating. The fast curing time facilitates a completion after 24 hours!

After full curing, the surface was inspected with an electronic spark detector (Holiday tester, high voltage 3 kV – according to NACE guidelines). No pinholes, blistering ore cracks were detected, the coating material showed a smooth surface. The specification required a total layer thickness of 1000µm, which was also tested thoroughly.
