Sucker rod coupling   Class T and Class SM coupling for sucker rods are manufactured as per API Specification 11B. For the thread cutting, we are using cold form rolled by displacing rather than by removing of material for making the coupling thread. The thread rolling cutting results in a compressive stress at the root of the thread, giving maximum strength to the traditional weak point of cut-thread couplings.   The couplings are available in full size, slim hole and over size.Also, combination couplings are available for different diameters (sub-coupling) for both Class T and Class SM couplings.

Thread protectors are used frequently in the oil and gas industry to protect pipe threads during transportation to the oil and gas fields. Thread protectors are generally manufactured from plastic or steel. Our thread protectors are the necessary counterpart of casing, tubing, drill pipe to protect the thread and connection from measurably impacting in transportation and loading and unloading. Our thread protectors are used for , tubing, drill pipe with size from 2-3/8 to 20 in, for thread connections of BTC, STC, LTC, EUE, NUE, NC, IF, FH, REG, PH-6, XT, HT-PAC, etc., also with different colors as required by clients.   * Some premium thread protector can be made, like PH6, HT-PAC, XT39, etc. * Color can be customized. * 100 % customer satisfaction for Quality and Reliability. * After machining all thread protectors undergo 100% thread inspection. * Both plastic and steel material can be made. * Both heavy duty type and light type thread protectors can be made.

In Henan, China, on Aug 28, 2023, Puyang Zhongshi Group, a renowned manufacturer and supplier in the oil and gas industry, is excited to unveil its latest product line – high-quality sucker rod centralizers designed to optimize well performance. As a trusted original equipment manufacturer (OEM), Puyang Zhongshi Group takes pride in delivering superior products while maintaining a competitive edge in both service and pricing. API standard sucker rod centralizer   Sucker-rod centralizers also may be called paraffin scrapers or rod guides. They keep the rods and couplings away from the tubing to decrease wear. However, special mechanical paraffin scrapers have been developed to also aid in keeping paraffin off the tubing and most of the sucker-rod length.   Rod centralizers with full-bore-fluted centralizers should be placed on or between the pump-handling pony rod, the sinker bars used above the pump, and the first two sucker rods above the sinker bars. Rod centralizers in these locations help stabilize the pump and valve rod and prevent valve-rod bending or breakage. When a tubing anchor is not used, rod centralizers will reduce tubing wear because of tubing helical buckling on the upstroke. Rod centralizers also may be used in crooked holes in which there are areas of concentrated tubing wear. working principle:   It connect with sucker rod, the centralizer casing OD is larger than the sucker rod coupling OD in order to centralizer rod. Centralizer casing has high strength wear resistant, so when contact with oil tube, makes the centralizer body wearing and reduces oil tube wearing so as to anti-wear (centralizer casing temperature resistant: 260°C, material: self-lubricating Ni-p plating material). The steel surface adopt Ni-p plating (the anti-corrosion technology) makes the centralizer has the ability of anti-wear and anti-corrosion. And it also suitable for the worse corrosion well condition.   Sucker rod centralizers play a crucial role in ensuring efficient oil extraction by providing proper alignment and spacing of sucker rods within wellbores. Recognizing the significance of this component, Puyang Zhongshi Group has developed cutting-edge solutions that enhance production efficiency, reduce wear on equipment, and minimize downtime. At [Your Company Name], we take full control of the manufacturing process from start to finish, allowing us to maintain exceptional quality standards consistently. Our state-of-the-art facility utilizes advanced technologies to produce sucker rod centralizers that are durable, reliable, and capable of withstanding harsh operating conditions often encountered in oilfield environments. With an unwavering commitment to customer satisfaction, Puyang Zhongshi Group offers tailor-made solutions for clients operating across Russian-speaking territories, the Middle East, as well as global markets. We understand the unique challenges faced by our customers and ensure prompt support through dedicated customer service teams trained specifically for these regions.

  Cement Basket is an effective aid in retaining and supporting the cement where weak formations and stage cementing is encountered. It is designed with Flexible Bow Springs, heat-treated under controlled condition for maximum strength and uniformity are welded to slip on collar and overlapping metal fins for flexibility and strength to support long columns of cement during primary cementing operation. The cement basket can restrict the downward migration of cementing fluids. They are usually installed above lost circulation zones, under stage tools, or near surface when a top cementing job is planned.   Casing cementing baskets type: 1. Non-welded, pressed by punching, high strength. 2. Compared with single bow centralizer, the restoring force is higher while the starting force and running force are lower.Therefore, it can be run in vertical, highly-deviated and horizontal wells. 3. Hinged design allows convenient field installation. 4. Can be unfolded and stacked flatly, saving storage and transportation cost.   API technical specifications:   Casing size NO. of Bows Total Length Basket O.D. Min.

Stop collars run on casing strings to maintain centralizer placement during running and cementing operations, keep centralizers and other casing attachments in place on the casing. Stop collars use set screws for increased holding force. The hinged design is for applications on upset tubing. These stop collars are available in slip-on for tight clearances and hinged for semi-tight clearances. The size is from 2-3/8''- to 30'' Hinged stop collars that use hardened inserts (dogs) to provide a positive lock onto the casing. The specially designed dogs bite into the casing, which provides the stop collar's strong holding force. The recommended torque on the bolt is approximately 25 to 35ft-lb. When properly installed, the hinged stop collar can provide a holding force up to 40,000lb. Slip-on stop collar with set screws is slipped onto the end of casing and up to the top of the joint to the desired location. The set screws are tightened to approximately 35ft-lbf. This style of stop collar can hold forces up to 20,000lb. They are designed for close-tolerance liner jobs as well as in the installation of cement baskets and cetralizers of different designs. This style stop collar is available in 3 1/2-in. to 30-in. casing sizes.     The installation for stop collars:   1.When using mobile screw type stop collar, slip over the casing, tighten the screws using wrench. 2.When using fixed screw stop collar, put the collar around the casing, insert the screw, and knock into screws by hammer. 3. When installing buckle type stop collar, buckle the stop collar onto the casing, lock with pin, knock into the screws.
