ISTI Plant Services

ISTI Plant Services is your complete solution to construction in the oil and gas industry. ISTI has the ability to provide turnkey construction services to your project. Plus, we have a track record of completing large jobs to the complete satisfaction of our customers. At ISTI, we are driven to deliver our projects on time and on budget. Our strategy includes the construction of skid based modules in our expansive shops in Tulsa, Oklahoma. After fabrication, assembly and coating, we trial fit and test in our yard, prior to shipment. This allows ISTI to deliver your product to the field knowing that we are ready for assembly. This process reduces your cost and speeds your job to final commissioning. The ISTI motto is "Your Job. Done Right."​ for a reason -- we meet your expectations with our high standards and professional execution.
