Superior Tank Co., Inc. is dedicated to the quality of our bolted steel tanks and has implemented the ISO 9001:2008 / API Spec Q1 quality assurance program. The program uses the internationally recognized ISO 9001:2008 program as a basis then adds other procedures relevant to the stringent requirements of the American Petroleum Institute (API) under the Spec Q1 standard.
The ISO 9001:2008 / API Spec Q1 program covers a wide variety of areas including steel tank ordering policies, engineering processes, manufacturing methods, shipping/transportation procedures and installation practices. All documents regarding the steel tanks are carefully governed and tracked ensuring any changes made after the initial order are communicated throughout the organization. Out of sync documents could result in the tank being manufactured or installed incorrectly. Also, our engineering department utilizes a central library of tank components which guarantees all steel tanks and parts are consistent from one tank project to another and components fit together properly. Another example of ISO 9001:2008 / API Spec Q1 is the method tank engineering designs are extracted and transferred to our bolted tank manufacturing department. The tank design is exported and component specifications are directly imported into the machinery used to fabricate each part. CNC machines are then used to precisely craft components to the proper size and profile. This allows complex shapes and radius cuts to be made with extreme accuracy. Tank components requiring welding are fused to one another using Automatic Robotic Technology (A.R.T.). This advance equipment allows us to produce 100% accurate and perfect welds for maximum strength. When a bolted steel tank is ready for shipment, the final Quality Control inspector verifies all tank components, hardware and materials are included. A report is completed and pictures are taken for record keeping purposes. To accurately track installation and any repair work, a field service management software is used. Various documents are signed off by the customer to signify key benchmarks.
Other processes and procedures have been established to standardize measurement tools and increase product reliably and consistency. Specific templates have been set up throughout the manufacturing facility to quickly and accurately verify certain key aspects of parts such as angles and material thickness. Even the tape measures used throughout the factory must be certified for accuracy!
The end result of this hard work is a steel tank which is exactly what was ordered, assembles as designed, and is manufactured to last.
