Ceramic-Backed Elbows & More
When it comes to fighting abrasion, US Systems “has your back.”
Maintenance costs, loss of material, and downtime can result from abrasive material wearing a hole in your elbow.
Mitigate these unnecessary costs with a ceramic-backed elbow that will last longer.
What is a Ceramic-Backed Elbow?
Ceramic backed elbows are specialized components used in pneumatic conveying systems to handle abrasive materials efficiently. These elbows are designed with a ceramic lining on the inner surface, which significantly enhances their durability and longevity. The ceramic material is highly resistant to wear and abrasion, making it ideal for applications where high-velocity particles can cause extensive damage to standard metal elbows.
In a pneumatic conveying system, materials are transported through pipelines using air pressure or vacuum. The bends in these pipelines, typically the elbows, are particularly susceptible to wear due to the impact and friction of the conveyed materials. By integrating a ceramic lining, the elbows can withstand this wear, reducing the frequency of maintenance and replacement, thus ensuring smoother operations and cost savings over time.
Ceramic backed elbows are available in various sizes and configurations to suit different system requirements. They are commonly used in industries such as cement, mining, power generation, and chemical processing, where handling abrasive materials is a routine task. The combination of toughness and resistance provided by the ceramic backing makes these elbows a reliable choice for enhancing the durability and efficiency of pneumatic conveying systems.
Our ceramic-backed elbow has a jacket across the back of the core elbow made of approx. 1/2″ of ceramic compound.
The ceramic compound has a Mohs Hardness of 9+, close to that of a diamond, which has a Mohs Hardness of 10.
Once the core elbow has worn through, the abrasion is transferred to the ceramic outer jacket and the core elbow continues to act as a static conductor.
