Hinged Welded Spring Bow Centralizer

Saigao's hinged welded bow spring centralizer is a high-quality welded product that meets or exceeds API 10D specifications. These centralizers combine a very high restoring force with a very low starting force. The centralizers feature bow springs strongly welded to its end collars. This welded design provides excellent downhole durability. Premium quality bows made of a special alloy steel with uniform hardness provide optimum performance and excellent stand-off. The end collars are available in a latch-on design with a high-strength steel-locking pin for maximum structural toughness. With a choice of six different bow heights, a perfect combination for casing/open hole configuration can be achieved.
