Wear Resistant Bend

Name: Wear Resistant Bend
Brand: Maxtech Engineers

Wear resistant bends are heavy-duty pipeline elbows used in pneumatic conveying lines of dust extraction systems where abrasive particulate matter changes direction. They are internally lined with abrasion-resistant materials such as ceramic tiles, high-chrome alloys, hardened materials, or polymer linings to extend service life under high wear conditions.

Working Principle

Particles conveyed at high velocity impact the bend walls. Wear-resistant lining absorbs impact and friction, reducing erosion and maintaining pipeline integrity. Without such bends, elbows wear quickly, leading to leaks and loss of suction.

Technical Specifications 11 PARAMETERS

Bend Type	Long-radius / short-radius elbow designed for high-velocity dust-laden airflow
