Perma-Pipe makes insulated pipes and leak-detection systems that keep fluids hot, cold, or safely contained as they travel underground.
Perma-Pipe makes the pipes that carry things nobody wants to see leaking: hot oil, chilled water, steam, and chemicals. Its core product is insulated pipe — pipe wrapped in foam and a protective jacket so the fluid inside stays at the right temperature over long distances — plus leak-detection systems that flag a problem before it becomes a spill. The simple problem it solves is heat loss and corrosion: a bare steel pipe buried in wet ground rusts and bleeds energy, so Perma-Pipe sells the engineered version that survives decades underground.
The company earns money by selling these systems to big institutional buyers: oil and gas operators, district heating and cooling networks, airports, hospitals, universities, and data centers. District energy is a big one — campuses and cities use central plants to make steam or chilled water and pipe it to dozens of buildings, and Perma-Pipe's insulated pipe is what makes that network efficient. It also sells leak-detection tech, where a sensor cable inside the pipe jacket signals exactly where a breach is happening. Customers pick it because the alternative is tearing up a road or a runway to find a leak. Perma-Pipe is small — annual revenue in the low hundreds of millions — and it is not a household name, but it has an unusual geographic footprint, with manufacturing in the United States, Canada, the Middle East, and India. The Middle East is a major market, largely because of oil and gas work, and the company has talked up growing demand tied to data centers and district cooling in that region. It is headquartered near Houston, Texas, which puts it close to the energy business it serves. The honest picture is a niche industrial company with lumpy results. Revenue depends on a handful of large projects, so a single delayed contract can swing a quarter, and margins are thin enough that execution matters. It competes against larger pipe and insulation makers and against local fabricators in the markets it serves. The growth story investors watch is whether district energy and data-center cooling become steady repeat business rather than one-off project wins.
The company already made pipes that carried hot or cold fluids. Now it added PermAlert, an electronic system that could sense a leak and warn people before a small drip became a big problem. That mix of pipe plus sensing would quietly shape much of what came later.
In 1994, PERMA-PIPE went public, but not as a standalone name: it was a subsidiary of MFRI, and shares traded on Nasdaq under the MFRI ticker. So investors who wanted a piece of the pipe business bought it wrapped inside a larger parent.
That same year, PERMA-PIPE bought key assets of its big competitor, Ricwil Piping Systems. Taking out a major rival gave it a stronger grip on the piping market.
PERMA-PIPE Middle East was registered in Fujairah, in the United Arab Emirates. This was the company's first plant in the region, a base for serving the Gulf countries where heavy industry and hot climates make insulated pipe a serious need.
The company won an order to supply insulated offshore pipeline for Shell's Perdido project, deepwater work that demanded tough, reliable pipe. It also won pre-insulated piping for heating and cooling at Princess Noura University in Riyadh, the first and largest university for women in the Middle East. Both jobs showed how far the company's pipes could travel from home.
MFRI named David Mansfield president and chief executive, starting an eight-year run that brought real prosperity. In the same stretch, PERMA-PIPE bought all the shares of Bayou PERMA-PIPE Canada and renamed it PERMA-PIPE Canada, tightening its grip on the north.
The parent board approved a rebrand, and MFRI announced it would become PERMA-PIPE International Holdings, trading under the ticker PPIH. The pipe business was no longer a subsidiary hiding inside a parent; it was now the name on the door.
David Mansfield left as CEO in June 2025. Saleh Sagr, who had been president and head of the Middle East and North Africa operations, stepped up to president and CEO days later, putting a regional leader in charge of the whole company.
Perma-Pipe Qatar agreed to buy a 51 percent stake in Welspun Special Coating, a joint venture in India that adds internal fusion-bonded epoxy coating, a protective layer applied inside pipes. The deal widened the company's coating abilities and opened a platform for domestic and export work in India.
In the second quarter of fiscal 2026, the company booked more than 67 million dollars in new orders across the Middle East and North Africa, Canada, and North America. Among them was its largest single leak detection project ever, plus growing work at its new Ohio facility, a sign the old pipe-and-sensing idea was still paying off.
Perma-Pipe has used its cash to fund operations and capacity rather than pay big dividends, and it is the kind of company where a few big backlog projects set the tone for the year. The bug in its business is also the moat: once a city or campus builds a district energy network, ripping it out is nearly impossible, so the pipe sold today tends to create decades of follow-on work.
