Well Tubing Coupling 107
The Well Tubing Coupling 107 is an API 5CT standard threaded coupling intended for oil and gas well tubing strings. It features a carbon/ alloy steel base with an outer tungsten alloy (WC/Co) overlay that provides wear and corrosion resistance. The coupling meets the API dimensional precision and thread sealing requirements, and the tungsten layer is reported to adhere without cracking according to GB/T5270‑2005 testing. It is supplied for import/export as a critical OCTG consumable.
In the OCTG market, couplings of this class are typically rated for tensile strengths of 150 MPa and are designed to withstand high‑pressure downhole environments. A typical tungsten alloy coating thickness of 0.2‑0.5 mm offers protection against H2S and CO2 corrosion, aligning with NACE 0177 standards. Standard API 5CT couplings are sized from 2 in to 4 in nominal diameter, providing flexibility for various tubing strings. The usual practice is to perform a hydrostatic pressure test at 1.5 times the design pressure to verify sealing integrity.
These couplings are used by drilling contractors, production engineers and workover teams to join tubing sections in wells worldwide. Importers generally order them in bulk to match the length of the tubing runs, and the supplier does not disclose a minimum order quantity, so confirmation is required. The source description mentions payment options such as L/C and T/T; buyers should agree on Incoterms like FOB or CIF before shipment. The product’s corrosion‑resistant coating and API compliance make it suitable for both new well completions and workover repairs.
| Coupling type | API 5CT threaded tubing coupling |
| Material base | Carbon steel / alloy steel |
| Coating | Tungsten alloy (WC/Co) overlay |
| Standard compliance | API 5CT (oil‑field tubing) |
| Corrosion resistance | Typical resistance to H2S, CO2, salt water and weak acids (per NACE 0177) |
| Coating thickness | Typical 0.2‑0.5 mm tungsten alloy layer |
| Thread specification | Standard API thread, precision sealing |
| Typical size range | Typical nominal sizes 2‑4 inches (DN 50‑100) |
| Packaging | Export‑ready bulk packaging with protective wrapping |
T.F.T. International New Material Engineering Co., Ltd. is based at Rm.2910, New Tech Plaza, No.34 Tai Yau St., San Po Kong, Kowloon, Hong Kong SAR. The company is classified as an imported‑tier supplier with a harbor trust tier on the platform. Its response data shows a 0 % response rate and zero average response hours, indicating that enquiries may need persistent follow‑up. The firm focuses on engineering new material solutions for oil‑field applications.
The present listing advertises the Well Tubing Coupling 107, highlighting its tungsten alloy overlay and API 5CT compliance. No specific certifications, production capacity or lead‑time details are provided, so buyers should request ISO or NACE test reports directly. The supplier notes that the coating passes GB/T5270‑2005 adhesion testing, but the exact performance data should be confirmed. No additional corporate background or client references are disclosed.
Well Tubing Coupling 107 is an API 5CT standard threaded coupling designed for oil and gas well tubing strings, featuring a tungsten alloy layer deposited on the outer surface for superior wear and corrosion resistance in harsh downhole environments. This coupling ensures leak-proof threaded connections between API standard tubing joints, commonly used in petroleum drilling, production, and workover operations across global oilfields. Ideal for import/export trade as a critical OCTG consumable component, the coupling meets dimensional precision and thread integrity requirements for reliable well integrity management.

Sourcing Well Tubing Coupling 107 from T.F.T. International New Material Engineering Co., Ltd. - Hong Kong Import Guide
Prior to ordering the Well Tubing Coupling 107, importers should verify the API 5CT compliance and request the mill test certificate for the carbon/ alloy steel base. Confirm the presence and integrity of the tungsten alloy overlay by asking for a coating adhesion report per GB/T5270‑2005. Ensure that the nominal size and thread class match the tubing specifications of the intended well.
Shipping from Hong Kong typically utilizes the Kwai Chung container terminal, but the exact port of loading must be clarified with the supplier. Lead‑time is not disclosed, so ask for a production schedule and agree on Incoterms such as FOB Hong Kong or CIF destination. Payment methods commonly include Letter of Credit or Telegraphic Transfer; discuss any advance payment requirements in advance.
Arrange a third‑party inspection focused on coating thickness, adhesion and thread dimensional accuracy before loading. Request the supplier’s ISO, NACE 0177 and API certification documents to substantiate quality claims. Upon receipt, perform a pressure test on a sample coupling to verify sealing performance, and retain all test reports for customs and downstream quality assurance.
