Isolation Liners
Isolation liners are protective barriers that fit onto various pipe supports to shield industrial piping systems from mechanical wear, corrosion, vibration, and noise, thus enhancing longevity and maintaining system integrity. These liners are tailored to fit different support structures and pipe dimensions.

RedLineIPS Isolation Liners
Isolation liners in pipe supports offer an essential layer of protection and functionality in industrial and construction settings. Their use spans across various applications, ensuring the longevity and integrity of piping systems. One of the most significant benefits of isolation liners is their ability to dampen vibration and reduce noise. This is crucial in environments where machinery and fluid flow generate significant vibration, potentially compromising the structural integrity of the piping system and creating a noisy, disruptive atmosphere. isolation liners effectively absorb these vibrations, protecting both the pipe and its supports from wear and damage, while also contributing to a quieter and more pleasant working environment.
Additionally, isolation liners play a pivotal role in preventing corrosion—a common challenge in many industrial settings. By providing a non-conductive barrier between the pipe and its support structure, these liners mitigate the risks associated with electrochemical reactions, moisture, and other corrosive agents. This prolongs the life of both the pipes and the support infrastructure, reducing maintenance costs and downtime. Furthermore, the versatility of rubber materials allows for liners to be tailored to specific environmental conditions, including variations in temperature, exposure to chemicals, or physical abrasions.
The following is some of the liner material available for order to complement Cogbill’s RedLineIPS heavy-duty metallic supports, noting that other materials can also be made available for custom requests.
PTFE (Polytetrafluoroethylene)
PTFE is a popular choice for liners in pipe clamps, saddles, and shim block assemblies, among others, due to its excellent chemical resistance, low friction properties, and resistance to corrosion. It is highly effective in preventing metal-to-metal contact and reducing friction. PTFE is known for its non-stick properties, making it suitable for applications involving chemicals and corrosive substances.
Neoprene
Fabreeka
Cotton Duck Pad
A “Cotton Duck Pad” is typically crafted from a robust, tightly woven cotton fabric known as cotton duck. Primarily composed of cotton fibers, it offers excellent strength and durability. It is available in different weights and thicknesses, with heavier weights being thicker and more resilient. In some cases, it may be coated with materials like PVC for added water resistance or fire-retardant coatings for enhanced safety. As a liner for pipe supports, it provides protection, cushioning, and insulation.
UHMW (Ultra-High-Molecular-Weight Polyethylene)
UHMW is a type of polyethylene known for its extremely low coefficient of friction, making it an excellent choice for reducing friction and preventing wear in shim block assemblies. It provides good protection against corrosion.
EPDM (Ethylene Propylene Diene Monomer)
PVC (Polyvinyl Chloride)
Nitrile Rubber (NBR)
Comparison Between Different Types of Isolation Liners
Each type of isolation liners has its own chemical and physical properties and characteristics, making some suitable for certain applications while others may be suitable for a wide range of uses. Their capability to handle certain temperatures or mitigate noise or corrosion, for example, can make choosing the right liner for your application can be daunting. To assist you in doing this, the following table summarizes the most important aspects of each liner. If you need more help, do not hesitate to contact us.

Choosing a RedLineIPS Isolation Liner Material
The choice of liner material depends on factors such as the specific application, the type of chemicals or substances the shim block assembly will be exposed to, and the environmental conditions. It’s important to select a liner material that offers the right balance of corrosion resistance, vibration damping, and noise reduction to meet the requirements of the piping system and the surrounding environment.
