non-welded bow spring casing centralizer easy to install and disassemble and convenient to transport with API 10D certificate
Spring made of 65Mn Ring made of Q235. Pin and wrench be supplid free of charge.
Centralizers for hole size from 4 1/2" to 20"
The centralization products are designed and manufactured utilizing superior steels and manufacturing processes combined with a quality assurance program that maintains high product standards required for successful cementing and completions.
Manufacturing many different styles and heights of centralizers to achieve the proper restoring and starting forces required for the wide range of down hole conditions faced in today's drilling operations.For severe dwon hole conditions that are encountered in the drilling of highly deviated and horzontal wells,recommend the use of the welded centralization products,ultimate tensile strength for these products averages 3 to 4 times higher than non-weld centralization products.
Casing centralizer
The types of the welded centralizer and non-weld centralizer are bow centralizer,semi-positive centralizer and positive centralizers.
Casing centralizer is a cementing tool which applied to centralize casing to improving the cementing quality.
· 1. The attached shapes are pressed by moulding instead of welding and rivet.
· 2. Removable and easy to use and transportation .
· 3. Starting and restoring force meets API 10D standards.
· 4. Alternative turbulence plates can enhance displacement efficiency effectively.
