3 Main Causes of Steam Leaks and How to Prevent Them
Steam leaks are a significant problem for steam-based plant operations, costing industries thousands of dollars annually. Beyond financial losses, steam leaks can result in energy waste, increased emissions, safety hazards, and decreased operational reliability. Plant managers need to prioritize addressing steam leaks, as fixing them can save substantial amounts of money and reduce plant downtime.
At RAK Industrial Services, we specialize in on-line steam leak repair. With our specialized equipment and techniques, we can fix leaks without the need for costly shutdowns. But first, it’s important to understand the main causes of steam leaks so you can take proactive steps to prevent them. Let’s dive into the three most common causes of steam leaks.
- Threaded Pipe Connections
Threaded pipe connections, developed in the 19th century, remain one of the most common causes of steam leaks. Although they’ve been in use for over a century, threaded connections have not kept up with modern demands.
During the heating, cooling, and operation cycles of a steam system, pipes expand and contract. This continuous thermal cycling can cause the threads of pipe connections to loosen or fail entirely. When this happens, steam escapes from the connection, leading to energy loss and potential safety risks.
How to Prevent Threaded Pipe Connection Leaks:
To prevent threaded-pipe connection leaks, it’s critical to move away from threaded connections entirely. The solution lies in using welded connections or tube-type connections that are more reliable under thermal stress. These methods create a stronger, more durable bond that can withstand the constant expansion and contraction of steam and condensate systems.
Why It Matters: Replacing outdated threaded connections with welded or tube-type connections significantly reduces the risk of steam leaks and improves system reliability.
- Packing on Standard-Type Valves
Gate and globe valves are common in steam systems, but they are often prone to leaks due to outdated sealing methods. These types of valves are typically sealed with packing, which can wear out and fail over time, particularly when exposed to high-pressure steam.
Valve packing wears down because of the lateral motion caused by the pressure system’s force. Since these valves are unsupported at the bottom, movement that isn’t strictly vertical can cause the packing to degrade, resulting in leakage. This becomes a significant safety concern, as steam can escape through the valve and put personnel at risk, especially if the flow directs toward the valve’s operating handle.
How to Prevent Leaks from Valve Packing:
Upgrading to ball valves or butterfly valves is an effective way to minimize leakage. These modern valve types are designed to operate at higher pressures and temperatures, with lower leakage rates than traditional gate or globe valves. In addition, a proactive valve maintenance program can help identify potential issues before they lead to leaks or failures.
Why It Matters: Ball valves and butterfly valves offer superior performance and reliability compared to traditional valve types, reducing leaks and improving system safety.
- Carbonic Acid
Carbonic acid, formed from the combination of oxygen and carbon dioxide in a steam system, is a less obvious but equally damaging cause of steam leaks. Over time, carbonic acid can corrode the weakest parts of the system, such as pipe threads, leading to the formation of leaks.
How to Combat Corrosion from Carbonic Acid:
The best way to combat corrosion from carbonic acid is by using welded connections or tube-type connections, which are more resistant to the corrosive effects of carbonic acid. Additionally, using stainless steel inside the condensate system can help prevent corrosion, creating a maintenance-free solution that extends the lifespan of the piping system and reduces the risk of leaks.
Why It Matters: Welded and tube-type connections paired with stainless steel protect your system from the damaging effects of carbonic acid, reducing leaks and maintenance costs.
