Product Description

                          API 10D Specified  Silp on Single Piece Centralizers  

The Single piece centralizer can be installed with 2 stop rings, 1 internal stop ring or casing couplings. The blades, top and bottoms rings are made of one piece to ensure the centralizer s integrity during rig operations. 
 
These are generally shipped in assembled condition only . This Centralizers undergos a special process of rust prevention before powder coating. 
 
 
 

PRODUCT NAME  SILP-ON CENTRALIZER

Rating	API Specification 10D and NQA 9001-2008.
Design features	- Smooth bow profile overall - Non-welded - Made to gauge - Integral bow design for increased strength and performance. - Zero weak points, such as hinges, welds, or mechanical interlocks. - Flexible to absorb both axial and radial loading. - Powder coated red finish
Performance	- Zero start and running force with exceptional restoring force. - Improved flow by area and improved pipe rotation. - Low torque and low drag units. - Improved zonal isolation.
Applications	- Used in most well applications and geometries for vertical, horizontal ERD, close tolerance, or under reamed well conditions. - The UROS units are recommended where tight restrictions through previous set casing are encountered; also recommended when increased structural integrity is required. - Specialized in centralization for under reamed hole sections. - Recommended to be run between limit clamps
Sizes available	4 1/2 to 20 in.; custom sizes available.
Minimum hole size	2 7/8 in. (4 in.) hole
Maximum hole size	20 in. (26 in.)
