At this exhibition, the company will display a series of products including:

Ø 25,000psi gas wellhead assembly

Ø 25,000psi check valve

Ø 25,000psi electric plug valve

Ø 25,000psi swivel flange

Ø 25,000psi active elbow

Ø 30,000psi manual slab gate valve

All above products have passed PR2F testing and certification.

The 25,000psi gas wellhead assembly, independently developed and manufactured by Hongda as China’s first set of its kind, was successfully applied in Well Qingyu-2, Tadong Block, Taklamakan Desert, Xinjiang in 2024. It has broken the foreign technical monopoly on ultra-high pressure, ultra-high temperature gas wellhead assemblies, and successfully filled the domestic application gap for domestic 25,000psi gas wellheads, paving the way for the application of high-end domestic gas wellhead equipment.

Its successful application has been widely reported by CCTV's Focus Talk, Jiangsu Provincial Party Committee News Network, Jiangsu.com, Xinhua Daily and other media.
