NST’s team of project managers and construction personnel have built a solid reputation for integrity and commitment to our clients. We employ and train some of the top tank builders in the nation for the sole purpose of installing and maintaining bolted storage tanks. We will help you select the RIGHT PRODUCT for YOUR UNIQUE APPLICATION and DESIGN requirements.

NST’s dedicated service team removes existing sealer and replaces it with new polyurethane sealer. They can also install optional HDPE plastic covers over exterior nuts and washers leaving a bright, clean, and refreshed tank. This process is a smart, cost-effective way to extend your tank’s service life.

Glass-Fused-to-Steel Tanks’ passive cathodic protection system consists of sacrificial anodes designed to protect the rebar, mitigate corrosion and provide protection to internal submerged metallic surfaces of the tank. The system is simple and reliable and requires only minimum maintenance that can last up to ten years.

It is important that tank inspection and maintenance be included as part of your system operation. Every tank will require periodic inspection and preventative maintenance. Exterior tank inspections are performed yearly. This can be done while the tank is in service. Interior inspections are performed per the manufacturer’s recommended interval and while the tank is out of service.

NST’s expert service team will give your tank a scheduled facelift. This is a smart way to maintain a beautiful tank. The team uses specialized cleaning equipment and techniques to remove stains, grime, mildew, and graffiti that inevitably build up over time, leaving a bright shiny, like-new tank in its place. The visual difference in the before and after is truly amazing and the value is clear.

NST offers tank insulation services to protect your tank and its contents from extreme temperatures. Not only is temperature control beneficial for the materials being stored, but by reducing the risk of damage and extreme heat, you’ll enjoy lower maintenance costs. Insulation comes in a variety of colors to fit your needs and can be installed with no interruption of service.

The bolted liquid storage tank has the ability to be expanded, which is an economical way to plan for future growth. Size your tank capacity for today’s requirements, but design your foundation for your future capacity. NST’s experienced crews will install our jacking system, unbolt the bottom connections and install the appropriate number of rings to raise the tank up to meet the designed maximum capacity. The only added cost at the initial purchase is the foundation designed for your maximum build-out. The additional cost of the heavier bottom rings comes at the time of expansion, providing an economical option for adding capacity to your system.

NST’s experienced field crews have successfully retrofitted our domes and covers on any existing tank including multi-terminal petrochemical sites.
