Wellhead  A casing spool, also known as a casing head spool, is an essential component used in oil and gas wellheads to provide a housing for the casing hanger and seal assembly. It serves as a transition piece between the surface casing and the blowout preventer (BOP) stack or Christmas tree. The key attributes of a casing spool include: 1. Materials: Typically constructed from high-strength alloy steel or other corrosion-resistant materials to withstand high pressure, corrosive fluids, and harsh operating environments. 2. Design: Features a flanged top and bottom connection to allow for the attachment of the casing head and the subsequent installation of the BOP stack or Christmas tree. 3. Pressure Rating: Designed to withstand the pressures encountered in the wellbore and provide a reliable barrier against wellbore fluids. 4. Sealing Mechanism: Equipped with robust sealing elements, such as metal-to-metal seals or elastomeric seals, to ensure a secure and leak-free connection between the casing head and the BOP stack or Christmas tree. 5. Size and Configurations: Available in various sizes and configurations to accommodate different casing and wellhead specifications. 6. Compatibility: Designed to be compatible with industry-standard casing hangers and wellhead equipment for seamless integration into the well construction process.     Tina Chen Sales Manager Company: PUYANG ZHONGSHI GROUP CO.,LTD Address: Mazhuangqiao Town,Puyang City,Henan Pro.,China Tel&WhatsApp:+8613213933762 Email: tina@zspetro.com Zhongshi Group Main Products: pumping unit,pumps(sucker rod pump,tubing pump,special pump,accept standard or customised),cementing accessories(float collar,float shoe,cement head,centralizer,rubber plugs,stop collar...)chrismas tree etc. API, ISO9001, ISO14001 certificates are approved.

Double Studded Adapter Flange (DSAF) or Double Studded Adapter (DSA) is a flange with a through bore and a ring groove on each side, drilled and tapped bolt hole sets on both sides and tapped end studs complete with nuts fitted on both sides. Unlike a spacer, the two sides are usually different in size and/or pressure rating. Double studded adapter flanges are commonly utilised to connect and adapt flanges with different nominal sizes, pressure ratings, and configurations.   Type Size Working Pressure Blind Flange 1-13/16” to 21-1/4” 2,000 psi, 3,000 psi, 5,000 psi, 10,000 psi, 15,000 psi, 20,000 psi Target Flange 1-13/16” to 21-1/4” 2,000 psi, 3,000 psi, 5,000 psi, 10,000 psi, 15,000 psi, 20,000 psi Testing Flange 1-13/16” to 21-1/4” 2,000 psi, 3,000 psi, 5,000 psi, 10,000 psi, 15,000 psi, 20,000 psi Weld Neck Flange 1-13/16” to 21-1/4” 2,000 psi, 3,000 psi, 5,000 psi, 10,000 psi, 15,000 psi, 20,000 psi   Tina Chen Sales Manager Company: PUYANG ZHONGSHI GROUP CO.,LTD Address: Mazhuangqiao Town,Puyang City,Henan Pro.,China Tel&WhatsApp:+8613213933762 Email: tina@zspetro.com Zhongshi Group Main Products:
