Shell North Sea - Pikotek product have been used in Interfaces with severalInstrument Diaphgram Blind Flanges of various ratings and sizes 2"-300# 3"-300,2"-2500#, 3"-2500# RF Flanges. The 2500# interface caused particular concern toShell as materials were 25% Cr Super Duplex Flange on one side on the other anInstrument Diaphgram Blind Flange consisting of 0.075mm hastelloy foil attachedwith a 25% Chrome Super Duplex modified Blind backing Flange. The Instrumentsuppliers were concerned the foil would be damaged if a Spiral Wound gasket wasused, hence Shell used VCS Pikotek.

Shell North Sea - Pikotek PGEs and VCS insulation requirement - HC GAS Des94 deg C with Teflon Energised Seal Ring Offshore Platform Shell Fulmar - Valve replacement program on the Fulmar Alpha Export Gas

Compressor system. The existing line specification was low temp 3.1/2 Ni CarbonSteel (ASTM A333 Gr. 3). Due to availability of material, the replacement valvesfor this system manufactured from Stainless Steel (ASTM A182 F316 etc.). As aresult Shell used Pikotek Sets for the reinstatement, service (H.C. Gas +Condensate)

PDO Oman- Harweel- Insulating gaskets for a high pressure 620 bar service withgas with 10% H2S in a production environment. In this instance due to the rigorousservice conditions Shell commissioned Inconel cores

Shell Malaysia Pikotek VCS used on offshore dissimilar materialsapplications on riser, manifold and in process areas. Here Pikotek isseen as a dual problem solver whilst isolating also reduces crevicecorrosion. An added advantage in Malaysia is as a cost saving facilityby removing the need to replace flanges

Shell Brunei Special VCS gaskets utilized on a 14 and 3 1500check valve that failed to seal on the RTJ. Due to the minimal land width

available Shell commissioned Pikotek to manufacture a custom gasket.Pikotek constructed a test rig at Yarmouth Testing in Maine to validatethe seals performance prior to manufacture.

Chevron USA. VCS used for isolation and corrosion protection bothonshore and offshore up to Class 1500

PDO OMAN - CP, The last three projects from PDO have utilizedPikotek gaskets for isolation, dissimilar flanges, and as replacements forRTJ gaskets particularly to protect flanges in sour service.

Shell USA - At Shell PL, they use VCS kits in ANSI 300, 600, and 900 mainly in Oilapplications. Shell Offshore in New Orleans uses VCS flowlok gaskets to increase therated working pressure in flanges. Services include oil and gas and pressure classesinclude ANSI 150-2500. Also CO2 levels are high and the inert sealing in the Pikoteksystem provides the required security .

NAM/Shell Holland Provide VCS product to NAM gas fields for CP applications. Other Shell Projects - PGEs and VCS insulation kits have been supplied to a number

of major Shell projects recently. These includes Sakahlin, Bonga, Gbaran Ubie andPearl GTL. All of these projects had some areas where Galvanic corrosion wasdeemed a risk and our products were used in dissimilar metal applications in areaswhere there was high levels of water present in the media (eg drainage systems)
