STAR 21 - SUBSEA GASKETS In subsea operations today for oil and gas wells, subsea completions at the sea floor are at increasing water depths with many completions between about four thousand (4,000) and eight thousand (8,000) feet of depth. Exploratory wells at water depths of ten thousand (10,000) feet or more are being considered. The hydrostatic pressure at such water depths is very high and along with containing internal system pressure the requirements on subsea gaskets are becoming ever more demanding We are very aware of the critical nature and application of this commodity and our personnel have many years of experience supplying on a Global basis. The range of subsea gaskets is extensive and the application chart adjacent provides a basic overview only All subsea gaskets are manufactured from fully traceable premium forged/rolled raw material only and machined precisely to extremely tight tolerances with particular care being taken over ovality, concentricity and flatness To enhance installation, subsea gaskets may be supplied with either silver plating or xylan or molybdenum disulphide coating, which provide excellent dry film lubrication during preloading and pack out microscopic irregularities between the gasket and flange/gland Resilient seals may be fitted should there be evidence of flange/gland damage Part numbers are constructed as follows: T - NB - RMT - PR - RS - PC T = TYPE (V, A, C) NB = NOMINAL BORE (02, 03, 13, 16, 18) RMT = RAW MATERIAL (LCS, 316, 825) PR = RATING (05, 10, 15) RS = NUMBER OF RESILIENT SEALS (00, 01, 02) PC = COATING (00 = NONE, ZN = ZINC, AG = SILVER, XY = XYLAN, MS = Mo S2)
