Products Description
TORICH ASTM A214 ERW Carbon Steel Heat-Exchanger and Condenser
Tubes
Standard | ASTM A214, A450 |
Matrial | Q195, Q215, Q235 etc Carbon Steel |
Size | OD: 6.76.2mm WT: 1-20mm Length: 1-12m |
Manufacture | Tubes are made by electric-resistance welding. |
Surface Condition | The finished tubes are free of scale., slight amount of oxidation
is not considered as scale |
Hardness Requirements | The tubes shall have a hardness number not exceeding 72HRB. |
Thermal Treatment: | After welding, all tubes are heat treated at a temperature of
1200℉(650℃) or higher and following by cooling in air or in a
cooling chamber of a controlled atmosphere furnace. Cold drawn tubes shall be heat treated after the final cold-draw pass at a temperature of 1200℉(650℃) or higher |
Test and Inspection | - Flattening Test - Flange Test - Reverse Test - Hydrostatic or Nondestructive Electric Test |

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
100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a
perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate
longitudinal and transversal defects.
