Description

Serpentine Tube for Heat Exchanger and Superheater in Waste Heat Recovery Boiler with 100% Hydrostatic Testing

Some of the quality tests carried out by us includes:

Corrosion Test Conducted only when specially requested by the client
Chemical Analysis Test done as per required quality standards
Destructive / Mechanical Testing Tensile | Hardness | Flattening | Flare | Flange
Reverse-bend and Re. flat tests Carried out in full compliance with relevant standards & ASTM A-450 and A-530 norms, which ensures trouble-free expansion, welding & use at customers end
Eddy Current Testing Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System
Hydrostatic Testing 100% Hydrostatic Testing carried out according to ASTM-A 450 norms for checking tube leakage, and biggest pressure we can support 20Mpa/7s .
Air Under Pressure Test To check any evidence of air leakage
Visual Inspection After passivation, every single length of tubes & pipes is subjected to thorough visual inspection by trained staff for detecting surface flaws & other imperfections


Supplementary Testing : Apart from the above mentioned tests, we also carry out on the manufactured products supplementary testing. The tests conducted under this include:

· Eddy Current Testing

· O.P Testing

· Radiography Testing

· Corrosion Testing

· Micro Testing

· Macro Testing

· IGC Testing

· Ultrasonic testing
