Product Description

Made in China API 10D Integrated Bow Spring Casing Centralizer

 
Bow spring centralizers, both welded and non-welded, are to help center casing in wellbore, allowing even distribution of the cement around the casing during cementing operations according to API 10D standard. The sizes cover 4-1/2"~20". 
 
Features: 
Designed for high restoring force and low starting and running force. 
End collars are designed with self-locking action, which are easy to assemble. 
Undergo special coating process to prevent it from rusting. 
Can be shipped in half assembled condition to save costs in shipping and storage. 
Specifications: 4-1/2"~20". Any special size or combination is available on request. 

The Single Piece Bow Spring Casing Centralizer is newly designed integrated steel flexible Centralizer used to centralize casing during the cementing stage of oil wells. Fully integrated (SLIP-ON) centralizers are manufactured in any diameter and as per customer requirements.
The blades, top and bottoms rings are made of one piece to ensure the centralizer s integrity during rig operations.

The specifications comply with API Spec 10D for starting compression, running down hole and expansion force.

These centralizers offer high fatigue strength for axial forces and radial side loads on bows during tubular rotation.

More flexibility as comparison to other spring bow centralizer.

Features:
1. Starting and restoring force confirm to API Standard.
2. More flexibility as comparison to other spring bow centralizer
3. Greater centering efficiency
4. Higher Stand Off.
5. 360° wall coverage for increased load bearing area.
Available Size: 4-1/2" to 13-3/8".
