Xixia Jinfangyuan Sealing Materials Co., Ltd. was established in 2004. It is located in Xixia County Industrial Cluster,Nanyang City, Henan Province.
The graphite packing with outer braided SS304 is braided by pure graphite yarns, and each graphite yarn is reinforced by stainless steel wire metal mesh, and the effect is enhanced by a barrier agent. The packing is stable in chemical properties, soft, easy to form, good in lubrication, high in thermal conductivity, difficult to harden and inert to chemicals. There is no danger of extrusion and deformation of packing at high temperature, and the leakage control is consistent, which is suitable for seals of high temperature and high pressure valves.
1. Product Feature
This high-performance packing adopts high-purity graphite core with outer braided SS304 stainless steel wire. It integrates excellent high-temperature resistance, outstanding structural rigidity and great tensile strength. The outer steel wire layer effectively prevents extrusion, deformation and carbon loss, with stable compression resilience, low friction and durable sealing performance.
2. Applicable Equipment
Suitable for high-temperature and high-pressure rotary pumps, reciprocating pumps, boiler valves, pipeline expansion joints, furnace equipment and industrial stirring devices. It can be used independently or combined with other soft packings to upgrade overall anti-extrusion and sealing stability.
3. Applicable Industries
Widely applied in thermal power, metallurgy, petrochemical, boiler industry, high-temperature pipeline engineering and heavy industrial manufacturing fields.
4. Compatible Media
Adaptable to water, superheated steam, high-temperature hot oil, air, flue gas, weak acid and weak alkali media. It keeps stable sealing effect in most high-temperature non-strong corrosive fluid and gas working environments.
5. Typical Working Conditions
Ideal for severe working conditions of ultra-high temperature, high pressure and long-term continuous operation. It is perfectly suitable for scenarios with frequent temperature fluctuations, high-pressure impact and easy oxidation, making up for the structural instability of ordinary graphite packing under extreme conditions.
