PERFORMANCE

In the design phase, we conducted expert engineering and metallurgy studies and kept in mind the total flow area around and through the filter, which allows our customer to pump at maximum flow rates without the worry of erosion.

Smooth operator

We also designed a filter that can be placed in and taken out of the sub with ease.

FLEXIBILITY

Steel and Non-Mag Downhole Filter Sub Rentals/ Drill Pipe Screens

MST has taken filter subs to a whole new level by using a thicker material on both the body and the end cap of the filter. We have also added a tungsten carbide coating to the end cap to 5" below, thereby adding additional strength and durability to the filter.
