Measurement While Drilling

Our parts are primarily machined with the alloys Beryllium Copper, Nitronic 50, and Stainless 17-4; aditionally, we are able to procure a wide variety of non-ferrous or ferrous alloys for a wide range of projects. We commit to stocking what we feel are essential parts in the MWD industry, with special focus on Tensor parts.

Drill Pipe Screens

ASI is your solution for drill-pipe screens. We stock screens from 2′ to 4′ in length and thicknesses ranging 7 to 16 gauge. Different situations call for different screens, thus we stock screens both high flows and slow flow applications. If we do not carry a screen that fits the conditions in which you are drilling, we have the resources to quickly design and produce a screen that will

In addition, we offer a full array of fabrication services including but not limited to: water jetting (up to 5 inches thick steel), plasma cutting, laser cutting and laser etching, rolling, forming, shearing, and welding. Sub racks, work benches, and tool stands are just some of the products we produce.
