API 6A casing head assembly for oil and gas wellheads
The casing head assembly is a core piece of wellhead equipment that supports the casing string and provides the lower connection for the Christmas tree / wellhead stack. CNPS offers API 6 wellhead equipment focused on casing head assembly / wellhead service for oil and gas applications where buyers specify API 6A-compliant configurations.
Procurement teams typically match the casing head to casing size, working pressure class, material class, and temperature rating for the well. Because published body copy for this product was previously empty, we do not list unverified weights or pressure numbers here. Share your wellhead datasheet or API 6A call-outs so CNPS can align the assembly, outlets, and hanger arrangement to your program.
