Hollow-Back Elbows
Hollow-Back Elbows are engineered to reduce wear in abrasive pneumatic conveying applications by capturing material within a fabricated back cavity. As abrasive product collects in this cavity, it creates a self-lining effect, allowing the material to abrade against itself rather than the elbow surface. This design significantly extends component life in high-wear areas.
Hollow-Back Elbows are constructed using a tube or pipe elbow, eliminating the need for transitions and supporting smooth material flow. Standard construction utilizes 10-gauge material, with options for thicker metal or abrasion-resistant steel plate available to meet more demanding operating conditions.
This elbow is a great solution for higher abrasion applications with material that tends to pack. Using Hollow-Back elbows for this type of product helps reduce loss of material and system maintenance time. In turn, this improves system efficiency and increases production.
Hollow-Back elbows are available in:
- Any degree and centerline radius (CLR)
- Carbon steel and stainless steel
- Pipe and tube
- Plain ends, flanged ends, grooved ends, and other specified ends
