API 4-12 Non-welded Casing Centralizer for Drilling

API 4-12 Oil Drilling Rig Casing Centralizer is an efficient tool for maintaining casing centering in well cementing operations, which can improve cementing quality, prevent borehole wall erosion, and ensure the integrity and production of oil and gas wells. We, Dongfanglong, can produce three different types of casing centralizers: Integral Centralizer, Non-Welded Integral Centralizer and Bow Spring Centralizer, which can be traded completely according to your needs. Our three types of casing centralizers are all in compliance with API standards, and the appropriate size and model can be selected according to different well conditions and needs. And the casing centralizer is one of the important tools to improve the efficiency and quality of oil and gas well construction, and it is an indispensable part of this industry.

Oil Rig Casing Centralizers

The integral centralizer is a kind of centralizer that fixes the ribs and diversion grooves on the outer wall of the casing by welding or riveting. It can generate centripetal force in the wellbore and keep a certain gap between the casing and the well wall, which is beneficial to the cement slurry. flow and solidification. The integral centralizer has the characteristics of firm structure, wear resistance and strong adaptability, and can be used for cementing operations in various vertical or inclined wells.

The non-welded integral centralizer is a kind of centralizer that adopts molding method to make the rib plate and the diversion groove into one. There is no welding or riveting gap, which avoids the phenomenon of stress concentration and embrittlement, and improves the strength and stability of the centralizer. reliability. The non-welded integral centralizer has the characteristics of light weight, small starting force and large restoring force, and can be used for cementing operations in complex well structures, such as horizontal wells, extended reach wells, J-shaped wells, and S-shaped wells.

Bow spring centralizer is a kind of centralizer with bow-shaped ribs made of ultra-high-strength spring steel, which can generate an outward force in the wellbore to keep a certain gap between the casing and the well wall, which is beneficial to the flow and solidification of cement slurry. The bow spring centralizer has the characteristics of simple structure, safety and reliability, good elasticity, and convenient use on site, and can be widely used in cementing operations in vertical wells or highly deviated wells.
