Plug System for Stage Cementing Collar / Stage Tools / DV tools / hydraulic stage collar

Plug System for Stage Cementing Collar / Stage Tools / DV tools.

The accessories of MSC/HSC stage tool including first stage plug, free-fall opening plug, closing plug, shut-off baffle and pumping-down opening plug. Those plugs are made of rubber or aluminum, and drillable.

1. The shut-off baffle is installed in the casing collar, one joint above the float collar.

2. The first-stage plug is used to isolate the first-stage cement and drilling fluid. on the end of displacement, the first stage plug lands and effects a seal against the shut-off baffle.

3. Featuring streamline shape and filled with lead, the free-fall opening plug can quickly free-fall to the lower sliding sleeve. When pressure is applied to the casing, it can open the circulation ports. 

4. The closing plug is used to isolate the second-stage cement and drilling fluid. When running to the upper sliding sleeve, it effect a seal in the stage tool. Pressure is applied to the casing and the circulation ports are closed. 

5. The pump-down opening plug is used for continuous cementing operation and in deviated wells. It can open the circulation ports directly and quickly, whereas the free-fall opening plug needs longer time waiting for falling.

Three types of stop collar for your choice

Three types of Stop Collar. 

Stop collar ( Stop ring ) also named position ring, stop circular, brake ring, etc, which used for holding the casing centralizer or cement baskets on any position of casing, and ensure the position of centralizer or cement baskets to meet the design requirements. 

The stop collar supplied by Quanxing has three types : set screw type, hinge bolt type and hinge pin type.

1. Set Screw Type Stop Collar ( ST-01) is a solid band stop collar without hinges, and use set screw to lock the collar to the casing. It's designed for close tolerance applications, there stop collars slide over the end of casing. They are used for locating liner centralizer, casing rigid centralizer and semi-positive centralizer on the casing string.

2. Hinge Bolt Type Stop Collar ( ST-02) is designed to latch on to the casing without having to be slipped over the end of the casing. There stop collars incorporate a hinge with the locking mechanism being located 180 degree form the hinge. A single bolt is used to tighten the stop collar does not produce markings or indentations on the casing after installation. 

3. Hinge Pin Type Stop Collar ( ST-03) is hinged and utilizes two ( or three) pins that are driven between the stop collar and the casing to effectively lock the stop collar to the casing. The pins are installed best by the use of an air impact hammer. These stop collars are most effective where low annular clearance is encountered.
