a) circular tube  R

b) Square tube  S

c) Rectangular tube  Q

 

Roughness:

The roughness of the outer surface of the composite pipe should be in accordance with the following regulations:

a) When the outer diameter of a circular tube is not more than 63.55 mm, the surface roughness of a circular tube should not  less than Ra 1.6 micron.

b) When the outer diameter of a circular tube is more than 63.55 mm, the surface roughness of a circular tube should not  less than Ra 1.6 micron.

c) The surface roughness of square and rectangular tubes should not be less thanRa 1.6 micron.
