Built with the purpose to surpass the API 10D and API Q1 specifications and endure demanding conditions, Sawan's Non-Weld Spring Bow Centralizers are designed for high restoring force with low starting and running forces so as to centralize the casing pipe in Vertical, Horizontal and Deviated Well.
The main purpose of the non weld bow centralizer is to reduce the effect of gas channeling by improving cement flow and thus resulting in a more uniform thickness between the casing and the wellbore. The company's ability to produce premium quality bows made from special alloy steel and manufactured in totally controlled heat treatment plant gives a uniform hardness and good spring action to the component which in turn results in optimum performance. The centralizers also undergo a special Iron Phosphate coating and then a polyester powder coating process known as powder coating which is provided to prevent the bow from rust.
The self locking feature of lips for holding bows to end collars and the integral hinges folded on the inside which are connected by high strength locking pin provides the maximum structural robustness. This feature also helps in convenient, economic and compact packaging of the product, thus reducing the overall shipping and storage cost.
