Authorized Chinese Premium Connection Threading: Seven Manufacturers, One Point of Contact

SWS helps overseas buyers coordinate Chinese premium connection requirements for OCTG accessories—from multi-connection tender packages to single-piece custom orders.

When a project specifies premium connections from several Chinese manufacturers, finding suitable threading suppliers can become a time-consuming part of procurement. Buyers need to check authorization coverage, confirm manufacturing capabilities and coordinate inspection, documentation and delivery.

Jiangsu Service Petroleum Technology Co., Ltd. (SWS) brings these requirements together through one point of contact.

Seven Chinese Premium Connection Authorizations

SWS holds premium connection threading authorizations from:

• TPCO

• Baosteel

• HYST

• Dalipal

• Shandong Molong

• Wuxi Beilai

• Linzhou Fengbao

The applicable connection types, sizes and product scope are confirmed against the respective authorizations during inquiry review.

For requirements involving other Chinese premium connections, including Changbao and Dehua, SWS can coordinate external threading resources, with the manufacturing qualifications and supply scope confirmed for the project.

For overseas tenders and procurement packages, this helps buyers reduce the work of locating separate suppliers and coordinating multiple connection requirements.

Send us your tender list or connection schedule so we can review the package together.

Verifiable Authorization and Traceable Quality Documents

Many overseas buyers do not have the dedicated gauges needed to inspect proprietary premium connections after delivery. Verification therefore starts before manufacturing: Is the authorization genuine? Does it cover the required connection? Does it belong to the facility performing the threading?

SWS supports buyers in checking the applicable authorization information. For premium connection products machined by SWS, we issue a quality guarantee certificate traceable to the corresponding order and products. Inspection requirements and supporting delivery records are agreed during order review.

Where external threading is required, the manufacturing facility and required quality documents are clarified as part of the supply arrangement.

Experienced Machining and Coordinated Surface Treatment

SWS has established machining processes and inspection practices developed through long-term premium connection manufacturing.

Our supply experience includes KOC-related projects, PetroChina and Sinopec projects, and projects in Ukraine, Russia, Brazil, the UAE and Malaysia. We have also supplied components within the supply chains of major international oilfield service companies.

Supporting processes—including sandblasting, copper plating, phosphating and QPQ treatment—can be coordinated where applicable to the material, connection specification and agreed manufacturing route.

One-Piece Orders and Urgent Requirements

The minimum order quantity for SWS premium connection products is one piece.

We accept customer-supplied material for machining and maintain selected special-material stock. For urgent requirements or highly customized orders of only one to three pieces, we assess material availability, machining feasibility and the earliest achievable delivery.
