The completion wellhead device refers to the oil (gas) tree, tubing head, casing head, and related accessories, which are used for suspension, support, control, regulation, and other oil (gas) equipment. In oil and gas extraction equipment, the sealing part plays a crucial role, and its performance is related to whether the oil and gas well can produce safely and efficiently.

Sealing of commonly used surface equipment for oil and gas extraction:

Oil and gas wellhead equipment seals;

Casing head and casing hanger seals;

Common valve seals.

JST has accumulated unique professional knowledge in designing high-performance sealing systems and polymer components, which can meet and exceed the continuously improving performance requirements for extreme temperatures, high pressures, and fugitive emissions.

We provide strong support to our clients with our strong technical capabilities in design engineering, testing, and R&D tools, such as using our proprietary thermoplastic material model for finite element analysis.

JST provides a variety of seals for manifolds and valves for various pressure control applications during drilling or Christmas tree production. In the previous process of valve installation by customers, JST’s gate valve stem and seat seal have already passed the PR2 tests conducted by more than 15 customers.
