JIC-4201B-316 (Graphite)

Product catalog summary

Material Properties:
The JIC 4201-B is a graphite sheet with tanged metal, suitable for various fluid services including water, oils, fuels, salt solutions, and mild acids and alkalis. It can withstand short-term peak pressures of up to 50 kgf/cm² (4.9 MPa) and temperatures up to 975℉ (525℃) in oxidizing service, 842℉ (450℃) for continuous operation, and 1200℉ (650℃) in steam service. The pH range is 0-14, and it is applicable for hot oil, oil gas, water, alkali, and salt solutions under specified conditions.

Physical and Chemical Properties:
The material has a density of 1.12 g/cm³, compressibility of 43%, and recovery of 16%. It has a tensile strength of 17.5 MPa (178 kgf/cm²) across the grain. The ash content is typically 1.8%, sulfur content is a maximum of 550 ppm, chloride content is a maximum of 50 ppm, and carbon content is typically 98.2%.

Gasket Design Data:
The gasket thickness ranges from 0.8 to 3.2 mm, with a gasket factor (M) of 2 and a minimum design seating stress (y) of 2500 PSI (176 kgf/cm²).

Warnings:
The material should not be used at maximum temperature and pressure simultaneously. It is a guideline only, and for conditions outside the specified range, consultation is advised. Gaskets should not be reused unless specifically indicated.
