Import Api Mandrel 1.5 - 5.5 M — Buy in Bulk from Supplier in Hong Kong

The API Mandrel 1.5 - 5.5 M is a downhole tubular component engineered for oil and gas extraction operations, available in lengths from 1.5 metres to 5.5 metres. The product is designed with corrosion resistance against H2S and CO2 environments, including saltwater exposure and elevated temperature conditions. The mandrel features a lightweight construction to facilitate handling and installation on rigs and platforms. Diameter specifications can be customised to match particular wellbore or completion requirements. The supplier, T.F.T. International New Material Engineering Co., Ltd., is based in Kowloon, Hong Kong SAR, and operates as an imported-tier vendor with harbour trust classification.

In oilfield service, mandrels of this type are typically manufactured from alloy steel grades such as AISI 4140 or 4130, selected for tensile strength and fatigue resistance under cyclic loading. The corrosion protection system usually involves alloy selection combined with surface treatments or cladding rather than simple coating. Standard API mandrel designs accommodate internal pressures and tensile loads specified in API 5CT and related tubular standards. Heat treatment protocols, including normalising and tempering, are standard practice to achieve the hardness range and impact toughness required for sour service. Thread forms follow API threading specifications to ensure compatibility with casing and tubing connections.

Primary applications include well completion, packer setting, tubing-conveyed perforating operations, and other downhole interventions where a solid internal mandrel acts as a pressure barrier or mechanical anchor. Buyers are typically oilfield service companies, drilling contractors, and national oil companies procuring for offshore or onshore projects. The listing indicates flexible minimum order quantities, with trade terms referenced as CIF and FOB. The supplier holds ISO and API certifications, though buyers should verify current certificate validity and scope directly with T.F.T. International New Material Engineering Co., Ltd.

T.F.T. International New Material Engineering Co., Ltd. is headquartered at Room 2910, New Tech Plaza, No. 34 Tai Yau Street, San Po Kong, Kowloon, Hong Kong SAR. The company is classified as an imported-tier supplier with harbour trust tier, indicating it sources or distributes products rather than manufacturing them directly at the listed address. The response rate is recorded at 0.00% with zero average response hours, which suggests the supplier has not engaged with buyer inquiries through the platform to date. Buyers should therefore expect to initiate direct contact via the provided address or alternative channels to confirm product availability and technical support.

The listing positions T.F.T. International as a provider of API Mandrels for oil and gas applications, with particular emphasis on corrosion-resistant alloys for sour service environments. The company does not disclose factory location, production capacity, workforce size, or client references in the available profile. No historical founding date, annual revenue, or specific manufacturing certifications beyond the general ISO and API mentions are stated. Buyers are advised to request a current certificate of conformity, material test reports, and evidence of API monogram licence during due diligence.
