    API Oilfield Stage cementing tool /stage cementing collar/API casing cementing accessories manufactures

    Casing Stage Collar
    The stage collar is a mechanical device utilized for two-stage cementing operations. It primarily comprises a two-stage coupling body, a first-stage plug, a baffle plate, and either a free fall opening plug (for non-continuous processes) or a pump-down opening plug (for continuous processes), along with a closing plug. Its purpose is to facilitate efficient and controlled cementing processes.
    1. The closing sleeve of the stage collar is equipped with an out-closing structure and a locking device to ensure secure engagement once closed.
    2. The stage collar is designed to prevent the accumulation of liquid in the loculum, a small compartment or chamber, during opening or closing. This prevents any liquid from obstructing or interfering with the proper functioning of the stage collar during operation.
    3. It is essential for the inner diameter (i.d.) of the upper and lower sub of the stage collar to match that of the casing in order to protect its body during drill-out operations when the drill bit goes down. This matching i.d. creates a protective barrier, mitigating the risk of potential damage.
    4. All accessories of the stage collar, such as drillable rubber or aluminum materials, are designed to be anti-rotational and facilitate easy drill-out processes.
    5. The stage collar can be equipped with a pumping-down plug, enabling efficient execution of continuous processes.
