Product Description

API Hydraulic Stage Cementing Collar for Oilfield Equipment:-

Stage Cementing Collar is used to effectively cement upper sections of the casing string after displacing cement around the lower section. The Multiple Stage Cementing Collar provides a means of opening and closing port holes for cement displacement and positive containment of the cement after displacement. API Drilling Cementing Two Stage Collar allows cementing of casing string in two stages. These tools set the standard for reliability, cost-effectiveness, and ease of use with outstanding built-in features and quality. They are the tools of choice when drilling requirements call for proven technology and low risk. The compact, simple design minimizes the number of moving parts and makes the tools easier to handle. The tool's clear opening and closing indications at the surface accommodate the hydraulic conditions of the well for safer, more efficient operations. The internal sleeves increase reliability and prevent premature opening from formation restrictions on applied pressures. It reduces total pumping pressure in long casing strings.
