Pressure Vessels

At Spallinger Millwright Services, our fabrication expertise also includes ASME coded pressure vessels. Our ASME “U” Stamp and National Board “R” Stamp certifications allow us to fabricate and repair pressure vessels to the highest standards. Similar to anything we do, we can accommodate hard to meet deadlines while providing top quality products.

We specialize in fabricating and repairing custom shell and tube heat exchangers, however we also have experience with various types of pressure vessels, including esAutoclav. U-tubes, welded tubes, carbon, stainless, inconell, retubing and installations are no problem. Our modern equipment, matched with our highly qualified personnel, allow us to meet all of our customers’ demands.

We have produced evaporators, condensers, strippers, sterilizers and vaporizers for the following industries:

  • Agricultural
  • Chemical
  • Refining
  • Ethanol and Biodiesel Production


We have the capabilities to fabricate, deliver, install and repair pressure vessels of nearly any size. Repairs, whether in our shop or at our customer’s location, can be performed on vessels we originally fabricated or those made by others.
