Premium quality Bows are made of special alloy steel and hot formed in totally controlled heat treatment plant to achieve the uniform hardness all over.

Spec and performance index of bow spring casing centralizer meet API Spec 10D.                                                    

The woven centralizer is connected by pin when in use, the unfolded centralizer can be stacked flatly for convenient storage and transportation.

Features

1) Bow springs made of spring steel which has been heat treated 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 that 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.
