Available in a number of sizes and materials, we are excited to bring this new product line to market.

While our official announcement is new, and we have been producing select variants of our dowhhole capillary tube product line for the past few years, our experience in producing the industry’s best downhole tubing began over a decade ago.

GEO PSI Cable & Tubing History

Beginning all the way back in 2008 our team developed our revolutionary 4mm Tubing Encapsulated Cable. This groundbreaking format came with a number of strength, reliability, and handling benefits. And as we ventured to make the industry’s best downhole cable, we began developing the processes and manufacturing techniques necessary to jacket our conductors in a stainless steel tube that can stand the test of time, and survive in even the most hostile downhole environments.

And with the introduction of our 4mm TEC product line, so too came the expertise and manufacturing know-how to reliably produce millions of feet of downhole tubing per year. As our specialized team developed their skills, we also developed an over-decade-long relationship with material suppliers, and we have developed custom manufacturing equipment to enable us to produce with the quality and consistency that we demand.

Fast forward to today and we have produced tens of millions of feet of 4mm, 1/4″, and 3/8″ tubing. And after several years of being the most trusted supplier of Duplex 2205 capillary tube for our partners in the Permian basin we are excited to bring our cap tube products to the world.

Premium Quality Capillary Tube

Tight tolerances, the best raw materials and manufacturing processes, and the proud record of having never had a downhole stress crack are just a few of the many factors that exemplify the premium quality of our capillary tube product line.

Our capillary tube line has been designed with a unique focus on oil and gas applications. We have built our brand around providing reliable solutions for our customers in the energy industry and we have done the same with our cap tube. This unique focus and our collective experience in producing products for downhole applications means that we understand and prioritize the performance requirements for products being deployed in such harsh environments.

While we have built this product line around the harsh environments found in the energy industry, its applications span a number of industries applicable for uses in everything from Hydraulic Control Lines, to Heat Exchanger Tubing, to Laboratory Instrument Tubing.

Across our several dedicated mills, we utilize an advanced forming and annealing process which ensures optimal durability, handling, and reliability in downhole environments. Once the strip is passed through a series of rollers to form it into a tubular cross-section, it is continuously welded along the seam with a gas tungsten arc welding (GTAW) process. Once it exits the tube mill, it is then passed through an induction coil and annealed at between 1,070°C – 1,100°C to achieve optimal durability and handling for end users.

To further ensure the quality and reliability of the end product we utilize continuous eddy current testing to detect holes and defects which while naked to the human eye, could pose a threat to long-term performance. This test, along with a final glycol pressure test are just some of many QC steps we utilize along the way to ensure our customers receive the quality and longevity they deserve.
