Import Api J55 Casing Pipe/ Oil Well Casing Pipe — Buy in wholesale FOB from Supplier in China

Oasis Oil Tools Co., Ltd. supplies API J55 casing pipe manufactured to API 5CT specification for oil, gas, and water well construction. The J55 grade designation indicates a minimum yield strength of 55,000 psi and minimum tensile strength of 75,000 psi, positioning it as a cost-effective solution for shallow to medium-depth wells where higher grades such as N80 or P110 represent unnecessary expenditure. The supplier offers both seamless and electric resistance welded construction, with seamless pipes ranging from 114.3 mm to 409.4 mm outer diameter and welded pipes from 88.9 mm to 660.4 mm. Wall thickness spans 4 mm to 20 mm across all product forms, with length ranges R1 (4.88-7.62 m), R2 (7.62-10.36 m), and R3 (10.36-14.63 m) available to match specific casing string designs.

The J55 grade chemistry permits slightly higher carbon equivalent than K55, with controlled manganese content to achieve the required strength through normalizing or normalizing and tempering heat treatment. Thread options include short round thread (STC), long round thread (LTC), buttress thread (BTC), and premium connections such as XC and XBY, alongside non-upset (NU) and external upset (EU) tubing threads for integrated tubing-casing programs. Surface treatment offerings encompass fusion-bonded epoxy, coal tar epoxy, and three-layer polyethylene (3PE) systems for corrosion protection in CO2-bearing or saline environments. The supplier lists third-party testing through SGS and BV, though buyers should request specific test scope and sample frequency.

This casing grade serves operators in conventional oil and gas development, water well drilling, and geothermal projects where internal pressure requirements remain below 3,000 psi in collapse-critical applications. Geotechnical contractors also specify J55 for borehole retention in foundation drilling where temporary casing is recovered. Oasis Oil Tools Co., Ltd. provides customized non-standard sizes by arrangement. Import procurement requires careful attention to coupling supply, thread compound compatibility, and thread inspection protocol, as these represent common failure points in low-cost OCTG sourcing.

Oasis Oil Tools Co., Ltd. operates from Fengquan Industrial Park in Xinxiang, Henan Province, postal code 453007, China. Xinxiang hosts a concentrated cluster of steel pipe and petroleum equipment manufacturers with access to railway freight corridors and inland waterway connections to major export ports. The company holds harbor trust tier status with no response rate data currently recorded, indicating limited transactional history visibility on the platform. The supplier profile does not disclose founding date, employee count, or production capacity figures.

The listing emphasizes API 5CT, GOST, and ISO9001 certifications, though certificate numbers, scopes, and accreditation bodies are not specified within available data. The supplier's product range extends across multiple API grades from H40 through V150, suggesting mill sourcing or inventory trading rather than exclusive J55 manufacturing. Buyers should request mill source identification, heat treatment records, and actual mechanical test results rather than relying solely on grade designation. Direct technical dialogue with Oasis engineering staff is recommended to confirm threading equipment capability, coupling inventory depth, and non-destructive testing infrastructure before placing material orders.
