Import Bonded Urethane Piston — Buy in Bulk from Supplier in China

Bonded urethane pistons from Jinan Tianwei Innovation Oilfield Equipment Enterprise are designed for use in duplex and triplex mud pumps used in drilling operations. These pistons consist of a metal core bonded to a polyurethane sealing surface, engineered to withstand high-pressure fluid transfer and abrasive drilling fluids. The urethane layer provides superior wear resistance and sealing integrity compared to rubber alternatives, reducing leakage and extending maintenance intervals.

The urethane compound used is typically a polyurethane elastomer with Shore hardness between 85A and 95A, offering a balance of flexibility and durability. The bonding process ensures no delamination under cyclic pressure loads up to 3000 psi. These pistons are manufactured to meet API 11K specifications for reciprocating pump components, with dimensional tolerances held within ±0.1mm. The design allows for replacement without full pump disassembly, reducing downtime in remote field operations.

Buyers include drilling contractors, oilfield service companies, and mining operations using mud pumps for circulation systems. The pistons are compatible with standard API pump models and are often used in high-sand-content environments where rubber seals fail rapidly. Trade terms are typically FOB Qingdao or CIF, with lead times of 20 to 30 days. Packaging includes individual plastic sleeves and cartons with labeling per API standards. Minimum order quantities are not specified and must be confirmed directly.

Jinan Tianwei Innovation Oilfield Equipment Enterprise is located at No.13 Shunshi Road, Jinan, Shandong Province, China. The supplier is classified as imported and harbor-trusted, indicating verified export history and logistics compliance. The listing does not state years in operation, production volume, or client references. No response rate or contact details are provided, suggesting limited or no direct communication capability through the platform.

The company specializes in oilfield equipment, particularly piston assemblies for mud pumps. There is no mention of ISO certification, in-house testing labs, or design engineering capabilities. The absence of response metrics and technical documentation implies a transactional supply model. Buyers should request product drawings, material test reports, and API compliance certificates directly before placing orders.
