Packing of graphite sheet with compression molding. It can be used from low temperature to high temperature without damaging the reciprocating and rotating shafts due to the self-lubricating of graphite itself, and it is easy to seal and
Steam, water, gases, heat medium, oil, hydrocarbon, organic solvents, volatile organic compounds, LNG, extremely low temperature fluids.
Anti-VOC Packing is composed as shown in the figure. The intermediate stage composed of several lowdensity graphite is a stress relieving property and it is economical because it can be used semipermanently due to various changes and thermal hardening phenomenon. By using Graphite & Inconel wire at TOP & BOTTOM, it guarantees excellent sealing at high temperature and high pressure. Packing ring plays a role to ensure compression by uniformly distributing compression force applied to Anti-VOC Packing.
This API Standard specifies the requirements for comparative testing of valve stem packing for process applications where fugitive emissions are a consideration. High temperature packing(s) shall be suitable for use at service temperatures –29°C to 538°C (–20 °F to 1000 °F) and temperature limited packing(s), suitable for manufacturer specified temperature range. Factors affecting fugitive emissions performance that are considered by this Standard include temperature, pressure, thermal cycling, mechanical cycling and corrosion.
