Tungsten Carbide Seal Ring/ Tc Ring
Renqiu Hengrui Cemented Co., Ltd. manufactures tungsten carbide seal rings using WC with a 6 % cobalt binder, most commonly supplied in the YG6 grade while YG8 and YG15 are also available on request. The rings are precision‑engineered for dimensions that typically range from 10 mm to 200 mm in inner diameter, with thicknesses between 2 mm and 20 mm, and they are offered in standard lengths or custom‑cut sizes as required by the buyer. The material composition delivers high wear resistance, corrosion resistance and compressive strength suitable for harsh petrochemical environments.
Typical industry specifications for seal rings include a hardness of about 2700 HV for the YG6 grade, a dimensional tolerance of ±0.02 mm and a ground surface finish of Ra ≤ 0.4 µm. The products are packaged in anti‑corrosion cases with desiccant packs, a practice that protects the rings from moisture during sea freight. Compliance with ISO 21920 and ANSI B16 is noted in the supplier’s description, providing a benchmark for dimensional accuracy and material performance.
Primary applications cover valve stems, pump shafts and rotary seal assemblies in petrochemical, oil‑and‑gas and chemical processing plants. Buyers such as equipment manufacturers and maintenance contractors typically seek these rings for their ability to maintain sealing integrity under high pressure and temperature. The listing does not disclose minimum order quantities, lead times or pricing, so prospective purchasers should request those details directly, along with preferred Incoterms and payment arrangements.

Sourcing Tungsten Carbide Seal Ring/ Tc Ring from Renqiu Hengrui Cemented Co., Ltd. - China Import Guide
Start by confirming the exact grade, cobalt content and hardness that your sealing system demands. Ask for a material test certificate and, if necessary, a dimensional inspection report to ensure the rings meet the required tolerances. Also verify the minimum order quantity and whether the supplier can meet any special packaging or labeling needs for your project.
Logistics for Chinese seal‑ring manufacturers usually involve FOB or CIF from the nearest port, such as Tianjin. Since lead time is not disclosed, request a production schedule and any options for expedited manufacturing. Payment terms often rely on a confirmed irrevocable letter of credit for first‑time buyers, but negotiate terms that suit both parties.
When importing, arrange a third‑party inspection at the factory or upon arrival to verify dimensions, surface finish and hardness. Ensure the supplier can provide ISO 21920 and ANSI B16 compliance documentation, as well as a certificate of origin. Clarify incoterms, insurance coverage and required customs documentation to avoid delays at the destination port.
