Double Wall Piping

Double-walled plastic piping is a popular choice in the chemical and industrial industries due to its numerous benefits. This type of piping is designed with two layers, providing an extra layer of protection against leaks and spills. Eastern Reliability has the experience to incorporate double-walled piping into our tank systems so that our customers can get the benefits of using double-walled plastic piping on chemical and industrial tanks.

While these products do not come standard with our tank systems, customers often ask us to design and include these products with the systems that Eastern Reliability delivers. Assmann’s double wall tanks go hand in hand with double-walled piping to ensure your secondary containment is provided beyond the storage tank itself.

Preventing Leaks and Spills

Double-walled plastic piping is designed to prevent leaks and spills as the inner layer of the piping is made from polyvinyl chloride (PVC) or chlorinated polyvinyl chloride (CPVC), which is a thermoplastic made by further chlorination of the polyvinyl chloride resin material, which is known for its exceptional chemical resistance. This material is able to withstand the corrosive nature of chemicals and other hazardous materials, ensuring that the piping remains intact and free from leaks. The outer layer of the piping acts as a secondary barrier, providing an additional layer of protection against leaks and spills from physical damage or weather. This is particularly important in industries where spills can have serious consequences, such as the chemical, wastewater, and oil/gas industries.

Another benefit of using double-walled plastic piping on chemical and industrial tanks is its durability. PVC and CPVC are extremely durable materials, with a lifespan of up to 100 years. This means that the piping can withstand extreme temperatures, pressure, and other environmental factors without deteriorating. This is important in industries where downtime is not an option, as the durability of the piping ensures that it will not require frequent repairs or replacements.

Effectiveness Of Double-Walled Piping

The key to the effectiveness of double-walled piping in preventing leaks is the space between the inner and outer layers. This space, or interstitial space, is designed to contain any leaks or spills that may occur within the inner layer of the piping. If a leak occurs in the inner layer, the liquid or gas will be contained within the interstitial space, preventing it from escaping into the environment.

In addition to the interstitial space, double-walled HDPE piping may also include leak detection systems that use visual or audio cues to alert operators to the presence of a leak. For example, a visual indicator may change color when a leak occurs, while an audio alarm may sound when a leak is detected. These detection systems help ensure that leaks are detected and addressed quickly, minimizing the potential for damage or injury.

Extreme Temperatures or Pressure Fluctuations

Along with being lightweight, double-walled plastic piping is also flexible, allowing it to adapt to changes in the environment. This is particularly important in industries where the piping is exposed to extreme temperatures or pressure fluctuations. The flexibility of the piping ensures that it will not crack or break under stress, which could lead to leaks and spills. The flexibility of the piping also makes it easier to install in tight or hard-to-reach spaces, which can further reduce installation costs.

Resistant To Corrosion

Double-walled plastic piping is also resistant to corrosion, which is a common problem in industries where chemicals and other hazardous materials are stored. Corrosion can weaken traditional piping materials, leading to leaks and other safety hazards. However, PVC and CPVC are highly resistant to corrosion, ensuring that the piping remains intact and free from leaks. This is why we can provide a custom system that includes all the piping, fittings, valves, and other components that are needed.

Why Choose Double-Walled Plastic Piping?

Double-walled plastic piping is a superior choice for chemical and industrial tanks due to its numerous benefits and when combined with our double-wall tank systems is the ultimate level of protection. Easter Reliability can design a tank system that includes a custom double-walled piping assembly that will fit seamlessly into your application.
