Product Description

1) Introduction

Stage collar is a tool used to complete the cementing operation into two times.

The stage collar should be used with centralizers above and below and a cementing basket positioned below the ports.

2) How to work

The operation of the collar is simple and reliable. It features a double locking mechanism consisting of a snap lock and ball lock system to assure that the ports are permanently locked closed after cementing is completed. Internal parts are designed to lock to prevent rotation during drill out and are constructed of easily drillable materials.

3) Features

a. Opening pressure can be adjusted and it is not subjective to hole angle.
b. The pressure-relief design prevents fluid trapping and compression during the closing phase of the tool's operation.
c. The I.D of upper/lower sub is the same as that of casing, but smaller than that of closing sleeve, which can minimize chances of damages to the closing sleeve.
d. The inner seats are made of an easily drillable NBR rubber/aluminum material. Both the opening and closing seats lock against rotation for easy drill out.
