Linzhang County Hengqiang Carbon Co., Ltd manufactures Oxidation Resistance Graphite Rings from flexible expanded graphite with a carbon purity of at least 99%. The rings are molded from flexible graphite tape into circular seals that meet international sealing standards. The supplier states that the product is suitable for high‑temperature and chemically aggressive environments. Production is carried out in Linzhang County, Hebei Province, China.
Flexible graphite rings are prized for their thermal stability, chemical resistance and compressibility. Typical temperature resistance for this material reaches up to 300 °C, while the density is usually around 1.8 g/cm³. Industry practice records a compression set of 10% or less after repeated loading, and a Shore D hardness near 70, providing reliable sealing under pressure. These typical values help engineers select the right component for demanding processes.
The rings are widely used in petrochemical processing, turbine generators, compressors, pumps and valve assemblies where steam, hot water or aggressive solvents are present. Plant engineers and OEMs often specify these components for their durability and self‑lubricating properties. The supplier offers both standard dimensions and custom sizes, and mentions that shipping can be organised on FOB terms, with MOQ negotiable according to the buyer’s needs.

Before committing to a purchase, obtain the supplier’s business licence, production certifications and any test reports that verify carbon purity and mechanical properties. Request a detailed Certificate of Analysis that includes density, compression set and temperature resistance data for the specific ring dimensions you need.
Clarify the incoterm that will be used - FOB is mentioned, but you should confirm the loading port in Hebei and any freight forwarder requirements. Discuss lead‑time expectations and whether the supplier can meet your delivery schedule, especially for custom sizes that may require additional machining time.
Plan for quality assurance by arranging an independent inspection or in‑plant testing of the first shipment. Verify that the rings meet the stated compression set and temperature resistance before acceptance, and ensure that payment terms protect you, such as a letter of credit that is released after successful inspection.
