1. TOLERANCE:

a) On Specified OD + 0.5mm (Ovality 0.5mm)b) The Inside Diameter of ubes shall allow insertion of a guage of 37.7mm dia for a minimum length of 200mm.c) On Wall thickness -10%d) The mass deviation on a single tube shall not exceed -7.5% of the specified mass.

2. ENDS:

Cut cleanly and nominally square with the axis of the tube and free from excessive burrs.

3. PROPERTIES:

a) Chemical (Maximum) C - 0.20%, SI - 0.05%, MN - 1.40%, P - 0.04%, S - 0.045%, AL - Min. 0.02%.b) Mechanical = UTS - 340 to 520 N/mm2, YS - 235 N/mm2 (minimum) & %Elongation on 5.65 S0 - 24% (minimum).

4. FLATTENING TEST WELD AT 90 DEGREES (COLD):

a) For weld : Distance between the platens, measured under load is not greater than 75% of the OD of tube.b) For Material :Distance Between the platens, measured under load is not greater than 60% of the OD of tube.

5. STRAIGHTNESS:

1 in 500 (In 1 meter it should not exceed 3mm).
