Casing head

The casing head is a fundamental core component of the wellhead equipment for oil and gas wells. It is installed at the top of the surface casing and is a pressure-bearing device in the well control system. It complies with API 6A and GB/T 22513 standards. It serves as the suspension and load-bearing base for multi-layer casings and as a wellhead connection and transition device for blowout preventers, tubing heads, and Christmas trees, ensuring wellhead pressure safety throughout the entire process of drilling, completion, and oil and gas production.
