Casing centralizers are essential traditional casing accessories. Following the completion of well operations, effective utilization of casing centralizers serves to reduce lower casing resistance, facilitating the smooth descent of the casing to its designated position.
1. These centralizers are specifically designed to provide high restoring force and low starting force for centralizing the casing pipe in vertical, horizontal, and deviated wells.
2. The premium quality bows are constructed from special alloy steel and are hot-formed in a meticulously controlled heat treatment plant.
3. The specifications and performance index of the bow spring casing centralizer adhere to API Spec 10D. The woven centralizer is connected by pin during use, and the unfolded centralizer can be stacked flatly for convenient storage and transportation.
