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.
Samples from each lot are tested to ensure that the hardness of the tube is within permissible limits.
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 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:
EDDY CURRENT TEST
Each and every tube produced at Tube Tech passes through the Eddy Current Test Head to check and eliminate the possibility of any surface defects on the tubes and ensure that only flawless tubes are sent for further operations like Finning, Bending etc.
All tubes and pipes produced at Tube Tech are compulsorily subjected to 100% hydro testing. Hydrostatic Testing can be carried out at pressures upto 70 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
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.
Dimensions of the Finned Tubes such as Fin Depth, Root Diameter, Thickness of Fin, Root Wall Thickness and Wall Thickness under Fins are checked with Profile Projector.
All products at Tube Tech are subjected to 100% visual inspection.
