ESP cable protectors are used to protect any configuration of ESP cables, control lines, encapsulated bundles, and etc in wellbore. Protectors use channels to prevent control lines or cables when assembly through tubing coupling. during completion service.    Applications:​ 1. Well Completion service 2. Artificial Lift 3. Intelligent Wells   Features: 1.Fit tubing size from 2-3/8" to 5-1/2". 2.Fit various coupling specification. 3.Multi channels can be adopted to protect esp cables and control lines at same time. 4.Carbon Steel and Stainless Steel can satisfy various wellbore.  

The hollow sucker rod is a kind of special sucker rod which is designed for oil extraction in oil well with high pour point, high viscosity and high wax content. Can exploit crude oil effectively. The hollow sucker rod consist of threaded joints, sealing and rod body. The rod body is made of seamless steel tube and the threaded joint is connected with the rod body through friction welding and heat treatment.  In addition to the center channel of the Hollow sucker rod downward into the heat carrier (hot oil, hot water, steam), chemical agents or down-heating cables to reduce the viscosity and melting wax, to improve the fluidity of crude oil, can also be used for sand, salt, small hole oil production and layered oil production. Meanwhile, the hollow sucker rod can drive downhole screw pump with large stiffness and large torque.   Technical specifications:   Rod diameter: 32mm, 34mm, 36mm, 38mm, 42mm, 48mm. Wall thickness of hollow rod: 5.0mm - 6.0mm. Nominal thread size: 1-7/16" - 2". Hollow sucker rod length: Hollow sucker rod 7.5m - 9m Pony rod: 0.6m - 3.5m  

Sucker rods are the important part in the artificial lift projects in oilfield.The sucker rod is a slender rod of the pumping well, it is connected to the polished rod on the top, and the pump is connected to the bottom to transmit power.   Steel solid sucker rods and pony rods of Puyang Zhongshi Group are manufactured to the highest quality standards to ensure reliable, consistent operation in every well application. The sucker rods series we usually supply are as follows,   1. Conventional Sucker Rod; 2. Special and High Strength Sucker Rod; 3. Sucker Rod with Centralizer; 4. Corrosion-resistant Sucker Rod; 5. Conventional Polished Rod; 6. Spray Metal Polished Rod; 7. Couplings for sucker rods and polished rods  

Oil downhole tools tubing drain nipples are for oil well sucker rod pump. The drain nipple provides a positive method to equalize the fluid level in tubing strings without mechanical manipulation. When the pre-set point is reached, a set of shear pins will break and the external sleeve will move down to uncover the ports in the inside nipple.   The hydraulic tubing drain nipple utilizes rupture disc technology to provide accurate and reliable actuation of drain opening downhole. Hydraulic tubing drain has been used in many types of wells to eliminate the potential hazards associated with pulling wet tubing strings. Its design is simple and utilizes applied hydraulic pressure to open an engineered metal disc which creates a fluid drain port to the casing annulus without restriction. Puyang Zhongshi Group produce hydraulic drain nipples. Welcome your inquiries.   Hydraulic drain nipple photo:  

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:
