Single piece bow spring centralizer
Single piece bow spring centralizer is a kind of integral casing centralizer without hinge which is the key equipment for oilfield drilling cementing operation. this kinds of centralizer is widely used in general vertical, slightly deviated wells ,deviated wells more than 30 degree less than 90 degree etc. it is also can be used for rotating pipe string application.
Our centralizers are designed and improved from weatherford,schlumberger and Halliburton.Single piece bow spring centralizer usually include two kind of production technology.one production process is produced from tubular product by cutting, linear cutting, hydraulic molding process etc. without any welding point and welding line. Another production process is that it is produced from one whole steel plate by cutting, linear cutting, reel-stretch punching, welding etc. it is only one welding line allowed on the surface.
CCSC technology API single piece centralizer have a good performance in open hole as well as cased hole. These high quality product is developed to meet and exceed API 10D specifications for using in highly demanding downhole conditions. Single piece centralizer combines the highest restoring force with zero start force and zero running force. The single piece centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells. The single piece centralizers reduce the effect of channeling by improving the cement flow, the results in more uniform cement thickness in the well bore. By reducing the pipe movement before cement sets in. our single piece centralizers are able to minimize gas channeling.
The single piece centralizers are one piece construction in special high strength steel which imparts excellent hardness and spring action ensuring an unmatched ability to come back to its original shape after undergoing rigorous stress loads conditions. They are available in size 4-1/2" to 20".Any special sizes we can designed according to client’s requirement.
Single piece centralizer without welding line we also call it offset bow spring centralizer, it is a robust, ultra-high-strength, one piece integral construction, and it is especially used for the long Horizontal hole.
All CCSC technology Single piece bow spring centralizer are made in compliance with international standards such as API standards, API 6A, API 5CT, API 10D etc.
We CCSC technology are dedicated to improve efficiency and safety in field cementing operations, all Single piece bow spring centralizer can be designed and manufactured according to user’s requirements.
