Graphite Packing supplied by Yuanbo Engineering Co., Ltd is a reinforced graphite seal designed for high‑temperature and high‑pressure environments. The matrix is reinforced with a mixture of steel wire, copper wire, nickel wire, carbon fibre, pre‑oxidised wire and glass yarn. It tolerates a pH range of 0‑14 except for strong oxidisers. Pressure limits are 125 psi (8.5 bar) in pumps and 2 500 psi (172 bar) in valves. Temperature capability spans - 400 °F to 6 000 °F (‑240 °C to 3 300 °C) in non‑oxidising atmospheres, up to 850 °F (‑240 °C to 454 °C) in oxidising atmospheres and to 1 200 °F (‑240 °C to 649 °C) in steam.
In the sealing industry similar reinforcement blends are used to improve compressive strength and minimise extrusion under pressure. Standard thermal conductivity for reinforced graphite is around 30 W/m·K, aiding heat dissipation in rotating equipment. The material density of 1.25 g/cm³ matches commercial grades. A low coefficient of friction reduces shaft wear, a common requirement for long‑run pumps. Conventional specifications also call for a rotary speed capability of about 25 m/s, matching the listed value.
Major users include petroleum refineries, chemical processing plants and gas turbine manufacturers that need reliable sealing under extreme conditions. Buyers should request bulk quotations, confirm packaging format - typically spool stock - and verify lead times directly with Yuanbo.

Before placing an order, importers should obtain the supplier’s mill test report, confirm the exact reinforcement composition and verify that the product meets the required pH and temperature specifications for the intended process. Requesting a sample for laboratory testing can reveal any incompatibility with aggressive chemicals that were not listed.
Logistics for graphite packing from China typically involve lead times of several weeks, but the exact schedule depends on the order size and chosen Incoterm. Buyers should clarify whether the price quotation is based on FOB, CIF or DDP and agree on payment terms such as a letter of credit or telegraphic transfer before shipment.
Quality assurance commonly includes third‑party inspection, dimensional checks and verification of density and thermal conductivity. Importers should ask for a certificate of conformity, material safety data sheet and any applicable test certificates to ensure the packing meets the required industry standards.
