The HDSH heavy duty hinged stop collar is a premium solution engineered for challenging well conditions, offering a highly reliable method of securing centralizers on the pipe to support effective cementing operations. Made from the same patented steel as Centek’s S2-HD Centralizers, each stop collar is heat-treated for enhanced strength and tempered for resilience. This robust construction enables the HDSH to withstand high axial forces, ensuring superior performance in demanding applications such as deepwater, highly deviated wells, and other challenging environments.

Featuring our innovative low profile integrated hinge with a unique "one-way" hinge pin, the HDSH combines exceptional strength with quick and easy fitment, even on the rig floor. With anti-vibration screw retention and fitment tested up to 50 lb-ft torque, the HDSH is optimized for maximum performance on casing grades up to P110, providing a durable, efficient solution for the most demanding wellbore conditions.

Performance ratings

Stop collar performance depends on the ability of the stop collar to hold the centralizer in place. This aids 'runability' and is measured by holding force and integral strength. To help with product selection we've added a rating to all our stop collar products for runability and strength.
