PVDF Encapsulated Incoloy 825 Control Line Tube

Encapsulation of several components (Flat Pack) provides a consolidation that will help reduce equipment and personnel that is needed to deploy multiple single components. In many cases, a flat pack is mandatory as rig space can be limited.Hydraulic Control Lines depending on the length of the application are subjected to raw materials. Orbital welds have become unnecessary in our industry as well completions are often greater than the standard yield of a mill produced coil. Our seam-welded tubing production uses Tungsten Inert Gas (TIG) welding machines. This process gives the operator the tools to perform a repeatable, high-quality weld. Our current equipment, together with cold-drawing machines allow us to produce OD Size ranges of 1/8” – 1” and Wall Thicknesses of 0.028” -0.095”. Common alloys for tubing products are 316L, 2205, 2507, 825, 625, and Monel 400.
