In 1961, PERMA-PIPE, Inc. was started as a division of the Midwesco company in Chicago to manufacture steam and condensate piping systems. Since that time, PERMA-PIPE has grown it's sales to $50 million with manufacturing facilities located on 25 acres in Lebanon, Tennessee and New Iberia, LA., which manufactures preinsulated pipe products for the oil and gas industry.

PERMA-PIPE became a public company in January of 1994 as a subsidiary of MFRI, Inc. Traded on the NASDAQ National Market under the symbol “MFRI,” PERMA-PIPE is the largest manufacturer of specialty piping systems for secondary containment and district heating and cooling in the United States.

From nearly the turn of the century through 1993, Ricwil Inc.manufactured district heating and cooling systems and heat traced piping systems as the brand-name leader in the preinsulated piping industry. In 1994, PERMA-PIPE acquired(1) certain assets formerly owned by Ricwil Inc., allowing PERMA-PIPE to improve processes and modernize the Ricwil product line. Adding Ricwil's years of design expertise and proven products to PERMA-PIPEs' unique capabilities greatly enhance PERMA-PIPEs' ability to satisfy the expanding needs of PERMA-PIPE's customers.

The industrial environmental marketplace is served by offering process piping, secondary contained piping, and leak detection/location systems through PERMA-PIPE/RICWIL industrial and environmental product Group. Process and secondary containment piping are important products for chemical plants, jet fuel systems, nuclear facilities and the food and beverage industries. We can also design our systems with a broad range of heat tracing options that include steam, fluid and electric. PERMA-PIPE's "Skin Effect" heat tracing system provides a cost effective solution for long runs of pipe that require consistent heat monitoring.

PERMALERT leak detection can be placed inside any of the secondary-contained piping products to detect and locate leaks in the piping system. Other leak detection applications such as sub-floors in clean rooms, computer rooms and semiconductor facilities benefit from this cable based technology for leak location in sensitive areas.

PERMA-PIPE and PERMALERT products are sold to a broad customer base through a network of local representatives and dealerships worldwide. Our manufacturing facility in Lebanon, Tennessee, delivers piping systems all across the United States as well as Canada and Mexico. The European, Middle East and Far East communities are serviced by our corporate office in Niles, IL.

PERMA-PIPE is proud to be the market leader in the piping industry with our commitment to quality and development of new products to meet the increasing needs of our customers.
