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

Product Introduction Puyang Zhongshi Group Co., Ltd, a professional manufacturer of oilfield cementing accessories, has introduced its high-performance 7" Reamer Shoe (Model: RS07000850) for reliable casing cementing operations. Combining the guiding function of a conventional guide shoe with the reaming capability of a reamer, this tool helps operators overcome tight hole sections, ledges and debris while ensuring smooth, efficient casing running and cementing. What Is a Reamer Guide Shoe? A reamer guide shoe, also known as a reaming shoe, is installed at the bottom of the casing string. During tripping-in, it performs two core functions: it guides the casing into the wellbore along the correct path, and its hardened reaming blades actively mill away obstructions, key seats and mud cake buildup so that the casing can pass through difficult intervals without getting stuck. When circulation and cementing begin, the shoe's flow ports deliver cement slurry efficiently to the annulus, ensuring complete zonal isolation. Key Features Eccentric Aluminum Guide Nose: The streamlined eccentric nose design centralizes the casing string, minimizes the risk of hitting ledges or washouts, and is easy to drill out after cementing. Six Tungsten Carbide Reaming Blades: Six hard-faced blades provide aggressive yet stable reaming performance, effectively removing tight spots, key seats and debris to reduce stuck-pipe risk. Optimized Cement Ports: Three Ø25 mm and three Ø20 mm flow ports allow smooth cement slurry displacement and help achieve uniform annular fill for better zonal isolation. API 5CT L80HC Body: The body is manufactured to API 5CT standard in L80HC grade, delivering high strength, hardness and wear resistance for demanding downhole conditions. Premium Casing Connection: The shoe features a standard 7" casing box thread (26 lb/ft), ensuring a secure, high-integrity, leak-proof connection with the casing string. API Class G Cement Fill & API RP10F III C Valve Seal: Standardized cement fill and valve seal grades guarantee consistent, high-quality cementing performance. M20 Set Screws: Two M20 set screws securely lock the internal components in place during running and cementing.

The polished rod clamp is of butterfly structure, it is fixed on the polished rod as retaining device for the rope hanger. It makes the pumping unit horse-head connected with polished rod through rod eye lifting device, and then the polished rod append and support the load of sucker rod string. The polished rod clamp is an important part connecting oil pump and sucker rod, it is required not only reliable, have a certain capacity, but also can not cause damage for sucker rod.   Polished rod clamps function: It has solved the problem of the polished rod body damage caused by the taper slip jamming dens pressing into rod body and greatly reduced the accident of seriously hurting the seal element to cause oil leakage due to the scar on the polished rod surface in the process of resulting stoke parameters or changing pump setting depth.   Puyang Zhongshi Group supply polished rod clamps with two kinds of material technology-casting technology and forging technology. The performance of forging type polished rod clamps is better than casting type.
