Import Api Well Tubing B Class — Buy in wholesale FOB from Supplier in Hong Kong

API Well Tubing B Class from T.F.T. International New Material Engineering Co., Ltd. is a steel petroleum tubing product manufactured to API 5CT specifications, featuring a tungsten alloy coating deposited on both inner and outer pipe walls. The tungsten alloy layer measures 40-60 micrometres in thickness with a hardness of 560-640 HV, bonded to the steel substrate per GB/T5270-2005 adhesion testing without cracking or peeling. This tubing is offered with special premium threaded connections, hydrostatic pressure tested to 95 MPa for 30 minutes and gas seal tested to 70 MPa for 15 minutes with zero leakage recorded.

The substrate material conforms to API 5CT B Class requirements, a standard H40-grade carbon steel selected for moderate-depth wells and less corrosive formations. The tungsten alloy enrichment, based on W-Ni-Fe or W-Co chemistry, provides abrasion and corrosion resistance beyond uncoated alternatives, particularly in sour gas environments containing hydrogen sulfide. The silvery white, uniformly bright surface finish indicates proper coating deposition. Standard shipping packaging applies as required by the buyer's logistics protocol.

This product serves upstream oil and gas extraction, well completion operations, and geothermal energy projects where tubing integrity under pressure and corrosive conditions is critical. Buyers include oilfield distributors, drilling contractors, and energy project procurement teams operating in the Middle East, North Sea, and North American basins. Importers should confirm thread specification (API round thread or premium semi-flush connections), exact coating chemistry, and third-party inspection certificates directly with T.F.T. International New Material Engineering Co., Ltd., as these details determine compatibility with existing wellhead equipment and downhole conditions.

T.F.T. International New Material Engineering Co., Ltd. maintains its registered office at Room 2910, New Tech Plaza, No. 34 Tai Yau Street, San Po Kong, Kowloon, within Hong Kong SAR. The company's supplier tier is classified as imported, with a trust tier of harbor, indicating a baseline verification level on the platform. Notably, the response rate is recorded at 0.00 percent with zero average response hours, which suggests the listing may be passively maintained or that response data has not accumulated. Buyers should anticipate potential delays in initial communication and plan sourcing timelines accordingly.

The listing focuses on advanced material engineering for oilfield applications, specifically tungsten alloy coatings applied to standard API tubulars. No information is provided about manufacturing facility location, production capacity, annual revenue, employee headcount, or client references. The company does not state ISO certification, API monogram licence status, or specific quality management accreditations. Importers are advised to request a current API Q1 or API 5CT monogram certificate, proof of coating application facility audit, and references from comparable buyers in their target market before committing to volume orders.
