Liaocheng Xinruyi Trading Co,. Ltd. supplies seamless carbon‑steel oil tubing manufactured in China. The tubing conforms to API 5CT standards and is offered in grades J55, K55, N80, L80 and P110. Standard outer diameters range from 60.3 mm to 114.3 mm, with lengths typically supplied in 9.14 m or 12.19 m sections. Each tube is designed to transport oil or gas from the reservoir to the surface after well completion.
The carbon‑steel grades provide tensile strengths from 415 MPa (J55) up to 758 MPa (P110), meeting the pressure‑rating requirements of most upstream projects. API 5CT specifies a minimum yield strength of 240 MPa for J55 and 415 MPa for P110, ensuring resistance to down‑hole corrosion and cyclic loading. Typical wall thicknesses for the listed diameters are 4.5 mm to 9.5 mm, delivering a standard pressure class of 1500 - 3000 psi. These specifications align with common OCTG practices for workover and production strings.
Buyers such as drilling contractors, field service companies and oil‑field equipment distributors commonly source this tubing for new wells and workover operations. Liaocheng Xinruyi can arrange bulk shipments under FOB or CIF terms, but exact MOQ, lead time and payment conditions should be confirmed directly with the supplier. The company’s harbor‑tier verification indicates it has passed basic due‑diligence checks, though response metrics are currently unavailable. Prospective importers are advised to request material test reports and API 5CT certificates before placing an order.

Oil tubing is a seamless steel conduit used in oil and gas wells to transport hydrocarbons from the reservoir to the surface after drilling completion. Manufactured to API 5CT specifications in grades such as J55, K55, N80, L80, and P110, oil tubing must withstand high internal pressure and corrosive downhole environments. It is a critical component of OCTG (oil country tubular goods) and is traded globally for upstream petroleum projects and well workover operations.

Before placing an order, verify that the supplier can provide up‑to‑date API 5CT test certificates and material test reports for the required grades. Request documentation confirming compliance with relevant standards, such as ISO 9001 if available, and ask for a recent factory audit summary. Confirm the exact outer diameter, wall thickness and length needed for your project to avoid mismatches.
Logistics for oil tubing are typically arranged under FOB or CIF incoterms, with shipment in standard steel coils or bundled sections. Lead times can vary depending on grade and quantity, so ask the supplier to specify the expected dispatch schedule. Payment terms are usually negotiated as a bank transfer against a pro‑forma invoice, with a possible letter of credit for larger orders; ensure these terms are clearly agreed before production begins.
Quality assurance should include third‑party inspection of the finished tubing, covering dimensional checks, wall thickness measurement and pressure testing according to API 5CT. Request the inspection report and any non‑conformance notices prior to shipment. Maintain proper import documentation, including the certificate of origin, test certificates and customs paperwork, to facilitate smooth clearance at the destination port.
