Composite Wraps
Altex personnel can repair piping, vessels, and tanks using composite wraps. Repairs are engineered/designed to the specific application. There is no need to shut down or drain a system. Wraps can be quickly installed, reducing costly downtime. Our Altex wrap and repair process allows your system to run again at the maximum operating pressure.
Air-Cooler Cleaning
Fouling on air-side coolers (fin fans) can significantly reduce cooling efficiency, impacting production and driving up costs. Altex provides a proven solution. Using environmentally friendly cleaning chemistry and custom-designed foaming sprayers, our technicians effectively clean air coolers on site. Organic debris (such as poplar fuzz) is easily removed, restoring heat transfer performance. Our cleaning chemistry is safe for both the environment and your fin-and-tube metallurgy, while our low-pressure application system ensures tube fins are protected throughout the process. With Altex, you get a safe, efficient, and cost-effective method to keep your air-coolers performing at their best.
Line Isolations – Crimping & Freeze Plugs
When leaks occur and systems must remain in operation, line isolation can be the only effective solution. Altex provides tailored line isolation responses based on your system requirements, using proven technologies to ensure safety and reliability. For both planned projects and unplanned emergencies, freeze plugs offer a safe and efficient option when a system cannot otherwise be isolated. Altex employs nitrogen-based freeze plug technology, which requires a freezable medium in a static (no-flow) line. In cases of uncontrolled leaks, Altex also offers pipe crimping technology. This method uses specialized hydraulic equipment to safely pinch the pipe, often combined with material injection to stop up to 100% of the flow. Stop rings can be applied to protect the pipe from shear, and once the leak is controlled, the crimping equipment can be safely removed. Altex pipe crimping is available for piping up to 3” schedule 80. With both freeze plugging and crimping capabilities, Altex provides rapid, dependable solutions to manage leaks while keeping your facility online.

FAQs
What is a heat exchanger and what does it do?
The purpose of a heat exchanger is to transfer heat between two or more fluids (typically gases and/or liquids) to regulate temperatures during production. These essential industrial components facilitate the efficient exchange of thermal energy without allowing the fluids to mix. Heat exchangers operate on the principle of thermal conductivity, where heat naturally flows from areas of higher temperature to areas of lower temperature. Heat exchangers are crucial in many industrial applications including power generation, oil/gas production and chemical processing. By controlling temperatures, heat exchangers help maintain optimal operating conditions for equipment and processes, improve energy efficiency by recovering waste heat, and ensure product quality in temperature-sensitive manufacturing operations. Heat exchanger designs can vary widely depending on specific application requirements, efficiency needs, and space constraints.
How to tell if a heat exchanger is leaking and requires service?
Detecting a leaking heat exchanger requires attention to several key indicators. Visual indicators with the exchanger may reveal obvious leaks. As well, unusual odors around the exchanger may also provide a clue that small leaks are present, many times in gas form. Many times, an exchanger may need to be by-passed and opened up to determine if there is a leak. In this case, to ultimately determine if there are any shell or tube side leaks, a hydro test is completed where a medium (water or glycol mix) may be pressured up and the contractor will monitor the pressure of the system to see if it remains steady. If the pressure in the circuit declines over time, then a leak is confirmed. A non-destructive examination (NDE) will then be ordered to locate the leak if the leak is not obvious. There are many hazards that are considered when managing leaking heat exchangers. These include environmental, safety, heat exchanger issues that may result in production issues and operating costs.
What happens when a heat exchanger fails?
When a heat exchanger begins to fail, it can create both production performance issues and potential safety hazards. When shell or tube side components begin to foul or scale for instance, heat exchange is negatively impacted and production costs, production efficiency or production losses can occur. Heat exchanger efficiency can drop significantly as the failing exchanger can no longer efficiently transfer heat between fluids, leading to increased energy consumption and inconsistent temperatures. System performance becomes erratic, with frequent cycling and potential shutdowns as safety mechanisms detect abnormal operating conditions. In pressurized systems, fluid leakage may occur, potentially causing contamination between previously separated fluids. The most serious consequence, particularly in combustion applications, is the possible release of noxious and/or combustion gases into the air stream. This creates a significant safety hazard that can lead to unacceptable safety concerns. Additional complications include accelerated wear on other system components as they compensate for the failing exchanger, leading to cascading failures if not addressed promptly.
How long do heat exchangers last?
The lifespan of heat exchangers typically ranges from 10 to 20 years, though this varies significantly based on several factors. Material quality plays a crucial role, with higher-grade alloys and corrosion-resistant materials generally lasting longer in challenging environments. Operating conditions significantly impact longevity—extreme temperatures, pressure fluctuations, and corrosive fluids can accelerate deterioration. Regular maintenance, including proper cleaning to prevent fouling and scale buildup, can substantially extend service life. The frequency of thermal cycling (heating and cooling) affects metal fatigue and can shorten lifespan when cycles are frequent. Water chemistry in liquid-based systems is particularly important, as improper pH levels or scale forming content can cause premature corrosion or scaling. With optimal conditions and diligent maintenance, some industrial heat exchangers can exceed their expected lifespan by many years.
How much does it cost to replace a heat exchanger?
Replacing a heat exchanger involves significant costs that vary widely depending on several factors. The complexity of the installation greatly affects labor costs, with difficult-to-access units requiring more time and specialized equipment. Heat exchanger size and capacity directly impact material costs, with larger units commanding higher prices. Material quality also influences cost, with stainless steel, copper, and specialty alloys being more expensive than standard carbon steel. For specialized applications requiring custom designs or materials, costs increase substantially. Additional expenses may include system modifications, permit fees, and temporary heating/cooling solutions during replacement. Given these variables, obtaining multiple quotes from qualified professionals is advisable when budgeting for heat exchanger replacement.
