A casing head is one of the most important pieces of equipment in any wellhead assembly. Sitting at the very top of the surface casing, it serves as the structural and pressure-sealing interface between the casing string and the rest of the wellhead system. In simple terms, the casing head is the "foundation" that supports every component installed above it and keeps wellbore fluids safely under control throughout the life of the well.

Every casing head we manufacture is engineered to meet stringent international standards. Full traceability, hydrostatic pressure testing, and non-destructive examination (NDE) are performed on each unit before shipment. Our products conform to API 6A and API 6B specifications, and can be supplied in H2S-resistant configurations compliant with NACE MR0175 for sour service applications.
Casing heads are widely used in onshore and offshore drilling, workover operations, and production wellheads. They are essential in:
With decades of manufacturing expertise and a commitment to precision engineering, we deliver casing heads that combine reliability, safety, and long service life. Our engineering team supports custom designs, fast lead times, and full documentation packages to keep your drilling program on schedule and on budget.
From high-pressure deep wells to corrosive sour-service environments, our casing heads are engineered to perform where it matters most. Each unit is manufactured from premium forged or cast steel, precision-machined to tight tolerances, and rigorously inspected to guarantee a leak-free seal. Optional features include multiple side outlets, back-pressure valves, and custom flange configurations to match your existing wellhead stack.
Our casing head designs prioritize ease of installation and long-term maintainability. Modular components reduce rig-up time, while standardized connections simplify integration with third-party wellhead equipment. Routine maintenance is straightforward, helping operators minimize downtime and extend asset life across the entire production cycle.
