Latch Type Welded Bow Drill Pipe Centralizers
Drill pipe centralizer is an important tool used to prevent drill pipe bending and deflection in drilling operations. It supports and holds the drill pipe in place, keeping it straight and ensuring the exact position and orientation of the bit. The drill pipe centralizer has significant advantages to improving drilling efficiency, prolonging the service life of drill pipe and protecting the environment.

Bow-Spring Casing Centralizer
Bow- Spring Casing Centralizer is a tool used for oil drilling. It can ensure that the cement environment outside casing string has a certain thickness . reduce the resistance when running the casing, avoiding sticking the casing , improving the cementing the quality . and use the support of the bow to make the casing centered during the cementing process.
It’s formed by one-piece steel plate without salvage. Through cut it by Laser cutting machine, then rolled into shape by crimping. The Bow- Spring Casing Centralizer has low starting force, low running force, large resetting force, strong adaptability, and is not easy to break during the well entry process, with large flow area. The difference between Bow -Spring Casing centralizer and normal centralizer is mainly in structure and material.
