About us

In February 2013, ISC Companies announced the addition of a facility based in Williston, ND. Now operating under the ISC subsidiary name Adams-ISC, the Williston location houses manufacturing and distribution warehousing as well as customer service. This addition helps us better serve the Bakken Formation in Eastern Montana and Western North Dakota as well as parts of Saskatchewan and Manitoba in the Williston Basin.

Adams-ISC, LLC. is a sister company of ISC Companies, Inc. and was formed in 2011 with the merger of ISC Companies, Inc. and Adams Machining & Welding in Rapid City, SD. We specialize in standard and specialty industrial equipment repair, manufacturing, and rebuild. We have an extensive inventory of hydraulic belts, power transmission components, and bearings available for purchase at our sales counter in our retail store. We take on those special, one-off projects that other shops simply will not touch. From start to finish, we can create custom machines and rebuild industrial equipment with the capabilities of our four focus groups: machining and fabrication; equipment and hydraulic repair; bearings, power transmission, and hydraulics; and pipe and vessel build and repair. We are equipped with field service trucks for onsite services including bore welding, frame repair, line boring, and equipment repair recommendations. We have talented machinists and certifications including: ASME "U"​ and "R"​ stamp, AWS certified welders, process piping per ASME standards, and steam piping per ASME standards. Other offerings include structural steel, Hotsy pressure washer rental, and substation manufacturing.
