Hinged bow spring centralizer is a traditional processed and economic centralizer,this kinds of centralizer is used in general vertical or slightly deviated wells.In the past,this kinds of bow spring centralizer is with the highest restoring force and the lowest starting force,so they are wildey used in the drilling or cementing jod,but now it is not the highest restoring force bow spring centralizer.It is simple way to increase the restoring force according to bow height.The higher bow,the more restoring force.

The bow of spring centralizer is made of 65Mn steel which is better tensile strength than general steel,but it is not up API standard,so we need process them by heat treatment in the high temperature and then annealing treatment in the cool water with special chemical material .What we do is to ensure the bow higher restoring force.This kinds of heat treated bow provides good centralization in the well when in fast running casing.

In order to increase anti-corrosion,we need use the special spring alloy steel,not simple 65Mn alloy steel according to customer's well environment.

For the collar of bow spring centralizer,we use Q235 steel.It is not restrict requirement in API standard.What we do is to meet the restoring force according to API standard.
