Flaring Test :
The flaring test serves to establish the forming behavior of tubes or pipes which is expanded to a specific degree. This flaring test is carried out in conformity with the code requirements. The specimen to be tested is expanded in a press to the degree specified. Defects which occur as result of this process are not permissible.
Hardness Test :
Samples from each lot are tested to ensure that the hardness of the tube is within permissible limits.
Tensile Test :
The tensile test specimen serves to determine the strength and ductility characteristics i.e. yield strength, tensile strength and elongation. Tensile tests are normally carried out at room temperature according DIN, ASTM, BS, and other common standards.
Flattening Test :
Flattening test mainly serves to detect microscopic internal and external flaws. It involves compressing a tube section between two planes placed parallel to a predetermined distance. Incipient cracks and internal or external defects which occur as result of this process are not permissible.
Non Destructive Tests :
Hydrostatic Tests :
All tubes and pipes produced at Tube Tech are compulsorily subjected to 100% hydro testing. Hydrostatic Testing can be carried out at pressures upto 120 kg /cm sq. The test pressure is achieved using high pressure Triple Plunger pumps. If specified, customers or their deputed inspection agencies can witness 100% hydro testing at our plant.
Pneumatic Testing :
For thin wall tubes Pneumatic Testing (Air under water) is done at up to 450 psi air pressure to check for any leakages in the tube.
Visual Inspection :
All products at Tube Tech are subjected to 100% visual inspection.
