    Detailed Description

    Cementing Shoe:
    Type A Shoe Product: Type “A” Packer Type Cementing Shoe
    Industrial Rubber's Type "A"Cementing Shoe is designed to protect the formation below the shoe from cement contamination.
    The rubber packing element, when expanded, not only retains the cement above the shoe, but also creates a seal between the casing and the formation. This is particularly important in the completion of water input wells.
    The Type "A" Cementing Shoe is made up on the casing string and run to the point where the casing is to be cemented. The tripping ball is dropped and allowed to gravitate to its seat.
    Pump pressure is then slowly built up in the casing. The pressure will move the inner piston downward, allowing fluid to enter the outside cylinder. Continued pressure will force fluid behind the packing rubber while moving the top of the rubber downward. This will expand the packing rubber to seal against the sides of the open hole.
    Pressure of approximately 600 psi will shear the bolts holding the sliding sleeve.  The sleeve will move downward, opening the cementing ports and locking the packing rubber in its expanded position.
    The tripping ball prevents cement slurry from entering the bottom of the shoe, and the cement leaves the casing through the cementing ports above the packing element.
    The packing element is designed to withstand a maximum weight of 500 LBS.  If the weight on the element is more than 500 LBS, it is advisable to run Cementing Baskets above the tool to support the cement column.
    All internal parts of the shoe are drillable.
    Type B Shoe Product:
    The IRI Type B Basket Cementing Shoe of casing is employed as:
    •	A Shoe to protect the Running-in String even through irregular and deviated holes. 
    •	A Basket to protect the formations below the shoe from cement contamination in the open hole, in washed out sections, in under-reamed and bell holes and/or in zones determined too weak to support the weight of the cement column alone.
    The Industrial Rubber Type B Shoe is an economical way to perform its special functions as described below:
    1.	The Shoe permits circulation through the guide nose while running in.
    2.	The Basket is held tightly against the core mandrel by a petal retainer for running in clearance.
    3.	After the setting depth is reached, the ball is dropped to release the basket petal retainer.
    4.	The ball gravitates to the seat, stopping circulation through the shoe. This diverts all the pressure to expanding the basket.
    5.	IRI Type B Shoe Baskets are made of Spring Steel Ribs reinforced with overlapping rubber Liners, which allow the expanded tool to better conform to the shape of the hole.
    6.	All internal parts of the shoe are drillable.
