Offer multi sectional PVC centralizer for water well casing or screen

Drill pipe tubing centralizer is a mechanical device that keeps casing from contacting the wellbore wall. A continuous 360-degree annular space around casing allows cement to completely seal the casing to the borehole wall. There are two distinct classes of centralizers. Since the bow springs are slightly larger than the wellbore, they can provide complete centralization in vertical or slightly deviated wells. However, they do not support the weight of the casing very well in deviated wellbores. The second type is a rigid blade design. This type is rugged and works well even in deviated wellbores, but since the centralizers are smaller than the wellbore, they will not provide as good centralization as bow-spring type centralizers in vertical wells. 

Main types:

1.BOW SPRING WELDED CENTRALIZER-TYPE PC

2.STAMPED SOLID RIGID CENTRALIZER

3.WELDED BOW SPRING CENTRALIZER

4.RIGID POSITIVE CENTRALIZER

5.SINGLE PIECE CENTRALIZER

6.NON WELDED BOW SPRING CENTRALIZERS

Design and Features:

• Unique design provides superior durability and rigidity capable of withstanding extreme downhole loads while maintaining standoff under large side forces
• Steel body construction can withstand extremely rough downhole conditions
• Fins and body are formed as a single integral component by the press forming process
• Helical fin design ensures circulation, hole cleaning and cementing
• Tungsten carbide hard facing can be applied to the fins for additional wear protection in extremely abrasive formations for casing drilling and casing reaming applications
• Compatible with all drilling fluids
• Steel shell centralizers are intended to ‘float’ between the casing couplers, or can be limited in travel between mechanically fastened Stop Ring
