St. Louis-based Watlow received the American Society of Mechanical Engineers's Boiler and Pressure Vessel Code, Section III, NPT certificate of authorization. This certification ensures that the components manufactured by Watlow meet the highest level of standards for the nuclear industry.

The ASME N-type Certificates of Authorization are well respected in the nuclear industry and are recognized globally as a rigorous verification of an organization’s quality assurance systems and processes. The NPT certificate allows Watlow to fabricate and stamp its products in accordance with the requirements of Section III. The certificate, along with Watlow’s existing ASME Section VIII certification, also positions Watlow to directly supply nuclear components to its customers, simplifying the supply chain and program management efforts.

“We are pleased to receive the NPT certificate,” said Kevin Schloemann, Watlow’s vice president and general manager for the energy processes business unit. “Watlow has continuously supplied the nuclear industry since its inception, and this certification further demonstrates a deep commitment to serve our customers. We provide industry-leading thermal solutions for many nuclear applications, and are proud to be recognized for the quality products we produce.”

Watlow offers many thermal products to the nuclear industry including pressurizer heaters, flanged immersion heaters, tubular heaters, core exit thermocouples, hot and cold leg RTDs, SCR power controllers and test systems used for reactor simulations.
