As a manufacturer and a supplier we produce cementing tools since 1997, and now we have almost 400 workers, the products cover cementing head/plug, stage collar, float equipment, centralizer and so on. Please contact me if you have need, and my email is Maggie@pyzs-group.com, WhatsApp is +8613939319501. Our website is www.pyzs-group.com The casing head is a kind of part of connecting casings and wellheads. It is used to support the weight of technical casing and intermediate casing and seal the annular space between the casings, which provides a transition joint for the installation of the tubing head, Christmas tree and other wellheads. The two-side-outlet design allows the casing head to supply cement, monitor and control well's sinking, and inject balance liquids etc. Casing head design features a 45 degree landing shoulder. This design avoids damage to sealing areas by drilling tools and prevents test plug and blow protector wedging problems when pressure is applied. This design also allows for accurate vertical positioning of annular seals, control line porting and test ports.
