Hinged Non Weld Bow Spring Centralizer
In this type of centralizer the end collars have hinges which split it into two halves. The bows are locked to the end collars via a special locking mechanism. These centralizers can be shipped in half reducing the freight cost.
Hinged Welded Bow Spring Centralizer
In this construction the bows of the centralizers are welded onto the end collars making it a Hinged Centralizer along with a Welded Construction.
Slip on Welded Bow Spring Centralizer
In this type of centralizer the end collars do not have any hinges hence these centralizers can ‘slip on’ to the casing.
Integral Stop Collars
All Bow Spring Centralizers are also available with integral stop collars where set screws are available on the end collars. In this case stop collars are not required, however this would not float on the casing.
