This paper aims to present innovative solutions in which organic composite materials can be utilized for solving corrosion problems. Two solutions are presented for corrosion protection of flanged pipework flange face forming and flanged coupling external protection. Flanged pipework is widely used in the industry. Aggressive chemicals running through pipework can encourage crevice and/or galvanic corrosion which can result in deterioration and subsequent leaking of flange faces. At the same time the operating environment can lead to external corrosion metal loss and flange boltseizing among others. These problems cause plant shut-downs waste of valuable resources and efficiency reductionnot to mention costly maintenance expenses. To overcome these actual concerns in an innovative way this paper presents flange face forming and flanged coupling external solutions. By utilizing epoxy materials in conjunction with forming techniques flange faces can be rebuilt and protected from further corrosion problems. By using a flexible and peelable elastomeric material flanged couplings and pipework can be isolated from corrosive environments peeled off if required inspected and resealed. With these practical solutions this paper will enable material selection engineers to make an informed decision regarding corrosion protection strategies for flanged pipework in harsh environments.

The paper reviews the history of Hydrogen Induced Stress Cracking (HISC) failures of duplex and super duplex stainless steels when deployed subsea and subject to CP at potentials around minus 1V.
This paper aims to present a novel class of pipeline protective lining materials that provide erosion-corrosion resistance combined with negligible wear to spray equipment. These coatings have been formulated with a blend of thermoplastic fillers rather than the traditional ceramic fillers used for erosion resistance.
