For nearly half a century Top-Co has been supplying drilling industry with oilfield casing cementing products including float shoes and collars, centralizers and hardware. Dedication to deliver tools of absolute reliability has been the result of our design and manufacturing excellence. As the industry continues to overcome new and challenging conditions Top-Co’s innovative technology is there to deliver solutions.



Float Equipment

Top-Co’s float equipment is a key component for running casing and performing cementing operations. During cementing operations, float equipment is essential for preventing back-flow while also serving as a landing point for wiping and displacement plugs. When surge pressures on the formation are a concern, Top-Co’s float equipment can be configured to auto-fill to prevent formation damage. Our float equipment is manufactured to the highest quality specifications and meets or exceeds the highest API standards. Float equipment is available in sizes 2-3/8” (63mm) to 30” (762mm) with a number of customizable options.

Inner String Cementing Equipment

Top-Co’s inner string cementing float equipment allows large diameter casing strings to be cemented through the drill pipe or tubing by stabbing/latching and sealing into the float shoe or collar. This eliminates the drill out of large quantities of cement, reduces circulating times, and reduces pumping pressures. Top-Co’s inner string cementing float equipment utilizes the HFX™ valve and is offered with or without a latch-in feature on the stinger.

Stage Cementing Equipment

Top-Co’s stage cementing equipment allows for 2 and 3 stage cement jobs. This reduces breakdown of weak formations due to high hydrostatic pressure from a tall column of cement and allows for effective zonal isolation around lost circulation zones. It also assists in selectively placing cement over specific casing intervals. Stage collars are available in different casing grades, weights, and thread connections. Plugsets are available for each stage collar application and are ordered separately. Both hydraulic and mechanical stage collars are compatible for use with external casing packers. A combination of two stage tools can be configured for three stage cementing operations.

Cementing Plugs

Top-Co’s cementing plugs are used during cementing operations for wiping the casing ID clean of drilling fluids and providing separation between mud, spacers, and cement. They also prevent over displacement of the cement slurry and indicate when the cementing job is complete. All plugs are designed to fit in conventional cementing heads.
