The MAXSTOP is a low friction, highly abrasion resistant, all composite bonded Stop Collar.

The parts are bonded in place, axially and radially, by vacuum injecting a modified structural epoxy system into a profiled cavity between part and tubular body, thereby eliminating the need for collars or screw mechanisms.

MAXSTOP can be used with any 3rd party centralizer or casing accessory.

Once installed, the tool rotates with the pipe.

MAXSTOP is non-corrosive, non-invasive, has extremely high holding forces.

MAXSTOP aren’t impacted by non-ovality or pipe API tolerances.

Available as both full wrap around & also multiple pieces for TFA/ECD improvement

The system is field proven and shows excellent results.

This 3-piece composite centralizer is precisely engineered with your well bore specifications in mind. Its design prevents debris from accumulating in front of the centralizer. This reduced drag drastically increases overall efficiency for casing placement.
Conventional centralizers restrict flow while pushing debris downhole during the casing run. The 3-piece composite centralizer allows unrestricted fluid flow as well as better debris dispersal resulting in lower ECD values. This improved circulation increases fluid distribution for a perfect cement job every time.
Incorporating Maxwell’s HELIX™ Offset Centralizer with your casing string reduces friction and drag, increases fluid flow, and improves efficiency for casing placement and cementing
