API Bow Type Spring Centralizer/Slip on Welded Double Bow Spring Centralizer/

Hinged Welded Double Bow Spring Centralizer

Hinged,welded ,heavy duty standard bow centralizer  is made of spring steel which has been heat teated and hardened tempered to ensure proper and consistent spring characteristics

The woven centralizer is connected by pin when in use, the unfolded centralizer can be stacked flatly for convenient storage and transportation.

It is designed and manufactured as per API 10D Standard,It is easy and convenient to use.

Hinged Non Weld Double Bow Spring Centralizers can be used in deviated wells which require low running forces. These are designed to pass through tight spots and doglegs. The double bow design makes these centralizers act as rigid centralizers under high side loads. The construction is with hinges and a non welded bow.

Advantages:

1. As a restructured enterprise of SINOPEC, we have manufactured cementing tools since 1997.

2. Perennial supply products for nationalized oil field.

3. Good cementing tools product line and workshops has been build, production quality and capacity is guaranteed.

Character:

1. It's finished well under mould pressing without any welding.

2. Starting and restoring force meets API 10D standards.

3. Easy and convenient to install.

4. Equipped with spinning disc to improve the displacement efficient.
