Slip On Welded Bow Spring Centralizer

Eneroil's Slip On Welded Bow Spring Centralizer is 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. Premium quality bows made of a special alloy steel with uniform hardness provide optimum performance. The end collars are slip-on types for maximum structural toughness. With a choice of six different bow heights, a perfect combination for casing/open hole configuration can be achieved. Furthermore, the installation of Eneroil’s slip-on welded spring bow centralizers on the casing pipe is very convenient, as the centralizer can be slipped on the casing pipe from one end at the time of installation.
