Custom ASME Pressure Vessels, Tanks, and Heat Exchangers:
Nobody Does It Better

No two industrial applications are identical. You may depend on certain features that can make your own processes better -- different sizes, different pressures, different materials. Sistersville Tank Works can build in the precision you need.

ASME Pressure Vessels

Up to 200 tons empty weight

In 1923, STW became one of the first fabricators in the U.S. to receive ASME code approval for tanks and boilers. Sistersville Tank Works holds ASME “S”, “U”, “U2”, “PP”, “R” and “NB” stamps. Today, we still maintain that ahead-of-the-curve philosophy for making our products better. The result is improved safety and performance in our customers’ applications.

Precise cutting, bending, fitting and welding of components is just the start. Extensive testing helps to ensure our products work better, safer and longer.

Specialized Industrial Vessels

Among the first products made by STW in the early years were boilers and tanks for the area’s booming oil industry. Today, our customers know they can depend on vessels that are bigger and better than ever. When high-alloy materials are required, STW crews know just how to work them, weld them and make them last, whether it’s hazardous chemicals or food grade material being stored.

STW is also a certified fabricator of API tanks.

Shell-and-Tube Heat Exchangers

Not every tank manufacturer can also build reliable shell-and-tube heat exchangers that can take a whole new level of close tolerances and precise assembly. Shell-and-tube exchangers are a regular part of STW’s product mix. Our customers insist on it for their installations.

Field Installation & Repair

STW has a team of field service technicians available to work on your installation, and to respond to any problems you might encounter. With existing equipment, our goal is zero tolerance for downtime. We’ll have mobile service units on the way in a hurry.
