Victaulic, the manufacturer of mechanical pipe-joining systems, has developed a new nitrile gasket for the maritime industry. The Grade T ‘Type A’ gasket, designed for use with specific Victaulic couplings and flange adapters, simplifies gasket specification and offers superior fire-resistant performance.
The nitrile Grade T Type A gasket can be specified for a wide range of services, eliminating the need to use multiple types of gaskets for different applications and simplifying gasket selection. The gaskets may be used in Class I, II and III piping systems outside boiler rooms in accordance with Table 7 IACS UR P2. Applications include open-ended piping containing flammable liquids heated above flash point, open-ended liquefied gas, flammable liquids below flash point, seawater, fresh water, sanitary/drains/scuppers, sounding/vent, air and other systems.
The gasket is DNV GL Type Approved as fire-resistant type when used with Style 07 ZeroFlex rigid couplings, Styles 75 and 77 flexible couplings and Style 741 VicFlange adapters. Grade T Type A gaskets in these couplings have passed fire testing in accordance with ISO 19921.
The Grade T Type A gasket can be used in oil-related services, including air with oil vapour, for temperatures up to 82°C, water-related services up to 66°C, and oil-free dry air services up to 60°C.
