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.
