Product Description

Description :

 

Tubing drains allow you to reliably drain the production tubing before pulling out of a hole. This prevents the process of pulling wet tubing, which is difficult and not environmentally friendly. Once on a surface, the tubing drain can be redressed for future use.

When installing the tubing drain, it is recommended to place the drain one or two joints above the top end of the pump. The tubing drain works off of pressure activation. You can change the shearing rating of the tubing drain by adding or removing shear screws. Once the screws shear, the sliding sleeve drops down and allows the production fluid to drain out .

Tubing Drain Application

During the production phase of oil and gas wells, it is necessary to place equipment downhole to facilitate or improve the production operation.

Tubing transports the oil and gas from deep in the well to the surface. Pumps are needed to bring the fluids to the surface.
