Product Description 9 5/8" hinged non weld bow spring centralizer Hinged Non Weld Bow Spring Centralizers are designed for high restoring force combined with low starting force for centralizing the casing pipe in vertical, deviated and horizontal wells. Feature 1)Bows can be configured for any hole dia from choice of five standard bow heights for optimum starting and restoring forces. 2)Compatibility of the bows with various end collar sizes reduces inventory requirements and provides tremendous flexibility of casing and hole size combinations. 3)Centralizers undergo a special process of rust prevention before painting .

The centralizers are built to gauge to offer easier, RIH, maximize standoff, and maximize the cement job. The centralizers are built mostly for passing through close tolerance situations and then opening back up into under reamed holed sections, or washed out sections, while still providing quality stand-off performance. Bow spring sections are based on a straight bladed principle, but are curved in both axial and tangential directions. This cross curvature conforms to the borehole wall, while the axial curvature changes proportionally as it encounters different loads. As the loads increase, the surface contact area also increases, reducing the load per square unit of area. This helps avoid compression and shear failure of the formation surface.Our non-welded bow spring casing centralizer is made of spring steel which has been heat teated and hardened tempered to ensure proper and consistent spring characteristics. 2) End collar hinges are folded toward inside. This way will minimize the collar stretch taht tends to occur when centralizers encounter tapers, commonly found in certain type of pipe connections. 3)A reinforcing rib stamped into the end collar. This way will strengthen and preserve it's round configuration during transport. 4)Several different spring bow heights that are available to accommodate most of casing-to-hole configuration. 5)Centralizers with built-in stop devices as well as those of uncommon sizes are available based on request.
