Field Welded Tanks

The field welded tank is your alternative to buying an oil tank off the shelf. The benefits of a field welded tank is that it can be constructed to fit any size area and is designed and installed from the ground up. If off the shelf tanks won't fit in your building's sub-basement or boiler room then a field welded tank is the solution you are looking for. CommTank offers field welded tanks in round, rectangular, or square configurations.

Do you want to maximize your storage capacity in an existing vault? We can custom build a rectangular tank to fit your storage room. Are you required to have 110% containment in the case of an accident or spill? We can field weld a secondary containment around your new or existing tank.

CommTank’s approach

  • Design and outline project for each specific site
  • Obtain permission and a tank installation permit from local fire department
  • Prepare the foundation for installation
  • Licensed technicians install the tank and all of its supporting components
  • Build a secondary containment system to prevent any oil from leaking

Why chose CommTank?

Markham Metal, who provides us with steel for our oil tanks, uses only virgin steel. Virgin steel is low carbon, fine grain, and is 100% recyclable. This is our steel of choice because of its reliability, weldability, durability, and resistance to corrosion. Our tanks are made from steel that is a minimum thickness of one quarter inch. We use only Standard 653 and AWS QC7-93 certified welders.

CommTank takes the initiative of handling the major details of the project, whether it is small or large, so that our customer has less to worry about. In accordance with the UL142 safety standards, CommTank pressure tests each new tank before installation takes place. We have trusted third party quality assurance inspectors design and test each tank prior to its use. CommTank contacts the local fire department in order to acquire permission to install the tank, and an installation permit. As long as the capacity of the tank being installed is less than 10,000 gallons there is no need to contact the state fire marshal. All parts and labor are backed up by a two-year warranty, and we ensure that the tank will have a life of at least ten years.

*CommTank is G12 licensed in the Boston area
*All tanks also meet NFPA 30, 30A, 31 and the Uniform Fire Code UFC Article 79
