Polar Service Center in Phoenix receives National Board R-Stamp

Polar Service Centers’ Phoenix AZ shop has earned its “R” stamp certification to perform repairs on DOT-coded cargo tanks and pressure vessels.

The ASME R stamp is issued by the National Board of Boiler and Pressure Vessel Inspectors. Certification involves a detailed audit of a facility’s procedures and quality systems.

“The National Board R stamp certifies our Phoenix location to test and repair all makes of coded pressure tanks, including welding and bodywork on DOT 406, DOT 407, and DOT 412 tank trailers,” says Mike Evans, president of Polar Service Centers. “It is an important capability especially for customers in Maricopa County, which has stringent cargo tank inspection and integrity requirements.”

Polar Service Centers opened its 8,000-square-foot facility in southwest Phoenix in July 2011 and began the R-stamp certification process shortly thereafter.

Four miles south of Interstate 10 at 4907 S 35th Ave, the Phoenix location has five and a half service bays. In addition to tank repairs, it provides pressure and vapor-recovery testing, MC330/331 retesting, periodic maintenance, and aftermarket parts for all makes of dry and liquid bulk tank trailers and truck-mounted tanks. The phone number is (480) 719-7953.
