Cast Aluminum Regular Bow Spring Centralizer Oil Drilling Tool
These high quanlityBow Spring Centralizer developed to meet and exceed API 10D specifications for use in highly demanding downhole conditions.Single piece centralizer combines the highest restoring force with zero start force and zero running force.The Bow Spring Centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells.
Features
1.Lightweight, 2-4 times lighter than other galvanized alloy, cast aluminium alloy and Cast Steel Rigid Centralizers.
2.The coefficient of friction is lower than that of steel and aluminum centralizers. The unique spiral design produces better cleaning power and improves cement replacement efficiency. The casing has obvious drag reduction.
3.High compressive strength and good wear resistance.
4.High temperature resistance, strong corrosion resistance.
