Bending tubing

The main component of the holder is the specially bended tube which allows the introduction of the whale probe" through a 10 mm hole in the housing ring of the engine. Then the whale probe" is easily positioned to the foot of one of the blades. After the inspection of the first blade root, the engine is rotated several degrees to allow the inspection of the next blade. 

The number of tube holes in a given shell is less than that for a fixed-tube-sheet exchanger because of hmitations on bending tubes of aveiy short radius. 

Note If rod binds, reapply rearward pressure on tube and heat up the spot weid area. Bend tube into proper alignment and reweid. If misaJiffnment is too grreat to correct hy this methodj. drill out spot weld, disassemble the entire unit and reeheok until problem area is discovered. Rework pieces as needed and start over with assembly step h.

The microriser, as illustrated in figure 1, is a laboratory scale entrained flow reactor. The actual reactor consists of a bended tube (bend radius 0.09 m) with an inner diameter of... 

The phenomenon of Dean vortices was first observed by Dean in a curved tube. The fluid in the central part is driven toward the external wall by the centrifugal force, which gives rise to a secondary flow. This results in the inward movement of the fluid near the wall and the outward movement of the fluid near the center (Fig. 3A,B). Curved tubes may be classified as torus, bends, helical coils (with a constant curvature), and spirals (with a variable curvature). Fig. 4 shows the helical coiled, spiral, and bend tubes. The hydrodynamics in a coiled tube can be characterized by a dimensionless number named after Dean and is defined as ...
