Product Description
Spiral Vane Structure Composite Centralizer Casing
1. introduction:
The composite centralizer features a low coefficient of friction, designed with one-piece composite construction. This is designed for horizontal application and maintains integrity in extreme temperatures and is resistant to high impact and wear. Even with its smooth, lightweight construction, it contains no vulnerable weak points.
These composite centralizer is available in Straight and Spiral Blade configurations, in various sizes.
2.Features
? The tool is made from a high temperature high-pressure injection moulded polymer.
? It is available in BOS21 standard grade polymer composite for most low friction requirements as well as BOS22 self lubricating polymer composite for low friction water based mud applications.
? The tools are available in Spiral (22-25°) or Passive (5°) angle bladed. configurations. Both blade styles are watermelon shaped to pass through casing and multi-lateral windows, washouts and tight spots.
