What To Know Before Chemical Storage Tank Installation

If you’ve recently purchased a
new polyethylene chemical storage tank or are planning on purchasing a poly tank, there are several ways to protect your storage solution from the start.

To ensure safe, effective operation and a long tank life, we’ve come up with seven guidelines to help you prepare for poly tank installation.

Your Guide To Proper Poly Tank Installation

1. Proper Equipment - Have a crane or forklift, with extended forks, available to move the tank from the delivery truck to its location. Using equipment that is not made to lift or move a sizeable tank can cause damage to the equipment and the tank itself. This can be a costly mistake that is important to avoid.

2. Safe Location - Ideally, your tank can be installed in the final location where stored chemicals are made available for use in your application at the proper stage. However, if the permanent tank location is not ready for installation, it is important to identify a safe, temporary location to place the tank until the site is ready for use. Make sure the location is out of way of operations and traffic from equipment that could potentially damage the tank prior to installation.

3. Smooth, Level Foundation - Prepare a smooth, level, solid foundation to install the tank on. Not having a level tank surface causes uneven stress on a tank and can eventually lead to problems down the road.

4. Plumbing Flexibility - Tanks regularly shift or flex during operation. For example, when a tank is being filled, expansion takes place on the lower sidewall. Natural events, like earthquakes, could shake or move the tank, applying stress to connection points. Engineering your tank fittings to accommodate such occurrences is important in avoiding unnecessary stress on tank fittings. Neglecting this step will cause plumbing that is too rigid, which could lead to leaking fittings that will require replacement and could damage other equipment or put employees in danger.

5. Determine plumbing supports and venting - When designing your storage system, Poly will help to ensure the proper plumbing supports and venting instruments are in place. If you’re unsure whether or not a pipe needs support or if your plumbing is stable enough, please contact us. Getting the right structural supports in place from the beginning is crucial to mitigating risk of plumbing failure.

6. Confirm Fittings Compatibility - Check to make sure all tank fittings are proper and are well-suited for both the type of tank being used as well as the chemical being stored. This step also includes checking any fittings not supplied by Poly Processing for chemical compatibility. Chemicals will react to different materials in different ways. For example, while the chemical you’re storing might be compatible with the polyethylene of the tank, it may corrode the steel used in the bolts of untested fittings, causing leaks.

7. Employee Warnings and Training - Attach the appropriate and required warning labels to the chemical storage tanks and surrounding areas, if necessary. Make sure all employees are trained in safe operations of the tank and handling the chemicals. Again, safety precautions taken at the onset of a tank installation set the stage for proper chemical storage and safer operations.

To prevent future problems with your tank and ensure safe operations, follow our proper tank installation standards outlined in the Poly Processing Storage Tank Installation Guide. This installation and operation guide contains helpful information for off-loading your new tank and specific fittings assembly instructions. In addition, after the tank is properly installed, please follow the tank start-up checklist and review the safety tips included in the guide.

Poly Processing Company also offers tank start up services.  A factory trained Poly Processing Service Technician will visit the site and help make sure things are set up and installed properly prior to chemical being introduced for the first time.
