• ELECTRO POLISHED SS TUBING WITH INHOUSE ELECTROPOLISHING FACILITY

Inhouse electropolishing facility ensures stringent control on the internal surface finish of the tubes

Stringent, uncompromising quality standards sets us apart. We understand the critical nature of the fluids that our tubes carry. Every batch of tubes are subjected to rigorous test of both destructive and non-destructive in nature at every stage. This ensures only the qualified tubes pass on to the next stage. A well organized document plan ensures every tube, if required, can be tracked back to every stage in its manufacturing process and finally to its melt in the mill. A well trained and committed quality assurance and documentation team ensures strict adherence to laid out quality plan.

ELECTROPOLISHING PLANT

Electropolish is an electrolytic process combining electric current and chemicals to remove metal. The peaks of burrs, folds, inclusion and other anomalies of a metal surface are dissolved more quickly than valleys as a result of the greater concentration of current over the protuberances. This electrochemical action produces a smooth surface. This is achieved when all parameters impacting the final electropolished surface are controlled. All our electropolishing is carried out inhouse where our trained and experienced quality control team is in full control of the process and its final output. Electropolished tubing is specified for many applications because of the surface smoothness that can be achieved, with fewer sites for trapping impurities. For the industry this means a purer product without danger of bio-film formation in the crevices.

  • Greatly retards bio-film formation
  • Improved cleanability during CIP / SIP
  • Reduced cleaning time due to smoother finish
  • Increased flow velocity due to lower friction
  • Increased resistance to corrosion
MECHANICAL POLISH

The mechanical polish process start with the simultaneous deburring of both ends of a tube. To achieve the desired interior surface finish, an abrasive material, fitted on to a pneumatic polishing head, rotates within the tube continuously. The residue is a fine metal powder that gets removed due to this process. This is finally removed by blowing a clean wipe through the tube before is it sent for visual inspection and finally surface measurement. Typically we can achieve a surface finish up to 0.5 μm Ra with this process. Our finishing shop is equipped with multiple lines of machines. Each machine can polish multiple tubes simultaneously.
