Product Description

Oil Well Non Rotating Top Cementing Wipper Plugs
 
Five Wiper cementing plugs feature five wiper rubber coated aluminum or plastic inserts available in 4 ½" to 20" casing sizes, as well as red rubber bottom plug and black colored top plug. The bottom plug rupture diaphragm has a 300 psi differential. Plus, the plugs are available for water and synthetic mud fluid systems.
Benefits include:
Bottom plug wipes mud sheath and other debris from the casing ID ahead of the cementTop and bottom plug reduce cement contamination with wellbore and displacement fluids.300 psi differential pressure required to rupture diaphragm and provide surface indication that bottom plug has reached the float collarPreventing cement over displacement and "wet shoe track"PDC drillableOperating range up to 350°FModerate plug landing plug pressure rangeCompatible with virtually all common fluid systemsThese plugs offer the following advantages:
(1) Spceial non-rotational device design allowing the plugs to drill out quickly;
(2) Special materials designed for easy drill out with PDV bits;
(3) High temperature and high pressure resistance.

3) API and ISO certified
 
4) Specifications: 4 1/2''---20''. More special sizes or combination are available as requested.
 
5) Material: Rubbers and Phenolic Resins.
6) Application
Our cementing plugs are specially designed with a positive wiping action to ensure that the casing is clean.
The top cementing plugs is designed to exert continous pressure on the casing wall.
The fins and tail section of bottom plugs provide positive wiping action. Fins also serve as a seal while cementing. 
 
7) Structure:
The core is made of aluminum or phenolic resins, depending on the application and well conditions.
The plug is made of high performance materials such as rubbers or phenolic resins. 
 
8) Using Method:

Place bottom plug before injecting cement, and pump the scrape to clean the well-wall. After all is set, build the pressure of 2-4MPa till the rubber diaphragm is broken, and thus circulation is formed. Then inject the cement, place the top plug, pump, set the pressure, and well cementation comes to an end.
