Applications and Benefits of Nonweld Bow Spring Centralizer


ZHENGZHOU,DEC 21,2016-Nonweld bow spring centralizer is used to help centralize the casing in the wellbore during the cementing operation,allow the cement to be evenly distributed around the casing string.This kinds of centralizer is designed for higher restoring force and lower starting&running force to center the casing in vertical and deviated wells.The nonweld centralizers are available in single bow and double bow(dual contact) type.
