316 SS Spiral Wound FG, CS OR

Spiral wound gaskets listed below consist of 316 stainless steel winding with flexible graphite filler, and a carbon steel outer ring. Spiral wound gaskets are metallic gaskets consisting of an outer centering ring (also known as OCR, OR, or an outer guide ring), metallic windings with a soft filler material, and a solid inner ring, or any combination of the three. These gaskets are manufactured to meet specifications as outlined in ASME B16.20 (previously covered by API 601). Spiral-wound gaskets can handle more harsh and varied operating conditions than non-asbestos sheet gaskets in general. They are available in multiple materials and configurations.

Technical Data

Governing StandardsSpiral Wound Gasket

ASME B16.20	Covers metal ring-joint gaskets, spiral-wound gaskets, metal-jacketed gaskets, and grooved metal gaskets with covering layers.
ASME B16.47	Covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for pipe flanges in sizes NPS 26 through NPS 60. Included are flanges with rating class designations 75, 150, 300, 400, 600, and 900 with requirements given in both SI (Metric) and U. S. Customary units, with diameter of bolts and flange bolt hole expressed in inch units.

Color CodesSpiral Wound Gasket

Spiral wound gaskets shall be marked with a color code that identifies the windings and filler materials. A continuous color around the outer edge of the centering ring shall identify the winding metal. The color identifying the filler material for NPS 1 1/2 and larger shall have four intermittent stripes spaced approximately 90 deg apart on the outer edge of the centering ring. Smaller size gaskets shall have a minimum of two stripes 180 deg apart. The colors shall conform to those listed in the table below.
