Pipe bending table
Collector as asbestos protector
Serpentine bending procedure
Mounting pipe on a welding table
Paste is applied after some pipe cleaning
Pipe is pressed on a plate with strings
Intermediate store (nearly empty)
You need experienced guys for bending.
But not to fast
Cleaning is really a brain killer
Welding preparation is a bottleneck
Pipe must be tight to a plate
Final splash before drying
Welding paste must be removed
Finished with welding at 2100
