The EUE PIN * NUE BOX Crossover from Tianjin Dalipu Oil Country Tubular Goods Co., Ltd is a threaded connection component designed to transition between EUE pin-end and NUE box-end pipe threads in oil and gas drilling systems. It is manufactured to API 5CT specifications and constructed from carbon steel alloy, engineered to withstand high pressure and corrosive downhole environments. The crossover ensures structural integrity where dissimilar thread types meet in a wellbore assembly.
The component features precision-machined threads compliant with API 5B standards for thread form, pitch, and taper. Material grade is typically P110 or J55, selected based on pressure rating and service conditions. Surface treatment includes internal and external coating to resist hydrogen sulfide and chloride corrosion, though the listing does not specify the coating type. Thread geometry is critical to prevent leakage under cyclic loading, and the design follows industry-standard crossover configurations for casing and tubing connections.
This crossover is used primarily in onshore and offshore drilling operations, production wells, and workover rigs where pipe string transitions are required. Buyers include drilling contractors, oilfield service companies, and pipeline integrators sourcing for new builds or maintenance. Bulk orders are common, with packaging in wooden crates or steel strapping. Trade terms mentioned include FOB and CIF, with payment via L/C or T/T. Buyers must verify thread inspection reports and hydrostatic test certificates for each batch.

Tianjin Dalipu Oil Country Tubular Goods Co., Ltd. is based in Jinghai, Tianjin, China, with a registered address in the Jinghai industrial zone. The company specializes in oil country tubular goods, including crossovers, couplings, and threaded connections. The listing confirms manufacturing capability but provides no details on facility size, workforce, or years in operation. Trust tier is 'harbor', indicating basic verification, with no third-party audit reports or production videos available.
The supplier does not disclose certifications beyond API 5CT compliance, nor does it list client names, production capacity, or quality control protocols. There is no recorded response rate or average reply time, suggesting limited buyer interaction on the platform. Buyers should request mill test reports, thread inspection records, and hydrostatic test certificates for each shipment, as these are not provided in the listing and are essential for downhole reliability.

Before ordering the EUE PIN * NUE BOX Crossover from Tianjin Dalipu, verify the API 5CT grade, thread inspection logs, and hydrostatic test certificates for each batch. Request mill test reports showing chemical composition and mechanical properties. Do not accept products without traceable documentation, as non-compliant crossovers risk catastrophic failure in high-pressure wellbores. Confirm the supplier can provide certification per API 5CT Appendix B and C.
Confirm Incoterms, lead time, and payment terms directly with the supplier. Standard terms are FOB Tianjin or Qingdao port, with lead times of 20 to 30 days after order confirmation. Packaging must include thread protectors and be secured in wooden crates to prevent damage. Payment is typically via L/C or T/T. Avoid suppliers who refuse to state Incoterms or demand full prepayment without shipping documents.
Upon receipt, inspect each crossover for thread damage, coating integrity, and proper labeling. Verify dimensions using API 5B gauges and check for surface cracks or forging defects. Retain a sample from each shipment for future reference. Documentation must include CoA, packing list, bill of lading, and export compliance certificates. If used in sour service, validate NACE compliance with lab reports before installation.
