Table D: For Working Steam Pressure upto Ibs per sq. Table F: For Working Steam Pressure above 1Ibs and upto 1Ibs per sq. Table H: For Working Steam Pressure above 1Ibs and upto 2Ibs per sq.

Table E: For Working Steam Pressure Ibs upto 1Ibs per sq. Apply a thin coating of Gruvlok lubricant to outside and sealing lips of the gasket.

Some applications require lubrication of the entire gasket surface. Slip-on flanges are also used as loose back-up flanges when Type B stub ends are used. Blind flanges – this is a flange without a centre bore, used to shut off a piping system or vessel opening.
