What Is a Casing Head and Why Does It Matter? 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. Core Functions of a Casing Head Casing suspension: Supports and hangs the weight of intermediate and production casing strings. Pressure containment: Provides a sealed barrier that isolates wellbore pressure from the surface environment. Annular access: Offers side outlets for monitoring pressure, circulating fluids, and performing well control operations. Connection platform: Acts as the mounting base for tubing heads, blowout preventers (BOPs), and Christmas trees.

Polished rod clamp is a crucial equipment to transfer force between pumping unit and polished rod. The polished rod clamps made in the plant adopt butterfly structure with hinge connection. When installation, users only need to clear the inner hole of the clamp and polished rod surface, evenly screw bolts on the clamps to ensure enough friction for the force transmission. It's easy to install and dismantle the clamps without damaging the polished rod.   The hot sale model are 1 1/2, 1 1/4 and 1", there are different stuctures, one bolt, two bolts and three bolts, the material can be casting and forging. All customized as per client request.   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 Website: http://www.zspetro.net
