Manufacture:
Tubes are made by seamless process.
The tubing may be stress relieved or annealed, as is considered necessary by the tubing manufacturer, to conform to the requirements of this specification.
Tolerance:
Straightness--The permissible variation for straightness of structural tubing shall be 1/8 in times the number of feet (10.4mm times the number of meters) of total length divided by5.
Squareness of sides- For square and rectangular structural tubing, adjacent sides may deviate from 90° by a tolerance of ±2° maximum.
Radius of Corners- For square or rectangular structural tubing, the radius of any outside corner of the section shall not exceed three times the specified wall thickness.
Workmanship, Finish, and Appeaerance:
All tubing shall be free from defects and shall have a workmanlike finish.
Surface imperfections shall be classed as defects when their depth the remaining wall thickness to less than90% of the specified nominal wall thickness.
Quality Control
1~ Incoming Raw Material Inspection
2~ Raw Material Segregation to avoid steel grade mix-up
3~ Heating and Hammering End for Cold Drawing
4~ Cold Drawing and Cold Rolling, on line inspection
5~ Heat Treatment, +A, +SRA, +LC, +N, Q+T
6~ Straightening-Cutting to specified length-Finished Measuring Inspection
7~ Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8~ Packing and Stocking.
