TYPICAL APPLICATIONS
Bulk Materials Handling - chutes
Fluids Conveying - gored (lobsterback) pipe bends, vents.

TECHNICAL DESCRIPTION
LOBSTER provides a multi-gored bend between two ducts. Ducts have circular cross-sectional shape. Duct size remains constant between inlet and outlet. From 2 to 10 gores permitted. Bend angle from 1 degree to 180 degrees. Collars optional, integral when specified Bend radius on inside, outside or centreline of bend. Up to 8 longitudinal seams per gore. Uses Triangulation development method as standard. Also `AutoNest' & radial line development.
