1. TOLERANCE a.On Specified OD + 0.5mm (Ovality 0.5mm) b.The Inside Diameter of tubes shall allow insertion of a guage of 37.7mm diafor 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) & %Elongatio
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).6. ZINC COATING : Minimum local coating thickness on the outside surface 40 microns. (GALVANIZING)7. MARKING : a) We can emboss mill sign "EN 39 UTP 3 or 4." online at every one meter interval over the length of pipe. b) We can do online stencilling as per customer needs.8. PACKING: Hexagonal type.9. MILL TEST CERTIFICATE:We can issue a MTC, certifying that the tubes supplied comply with this Standard.
