Quality Assurance / Quality Control Certification Achievements
     
 

Niton Valve Industries' Quality Assurance System is created to guarantee the consistent quality expected at an international level. Niton Valve Industries achieves its quality requirements, in part, by selecting sub-suppliers that meet their qualification criteria and that can consistently execute its activities in accordance with their Quality Assurance System.

Niton Valve Industries can ensure that the valves they manufacture comply with the most sophisticated technical and contractual requirements by coordinating and optimizing control of sub-supplier, manufacture, in-process inspections and examinations through the final pressure test.

NON DESTRUCTIVE EXAMINATIONS INCLUDE:

  • Dye penetrant (DP) examination on surface
  • Radiographic Examination (RT): Gamma Ray or X-Ray
  • PMI (Positive Material Identification) using Metorex make portable Alloy Analyzer
  • Paint dry film thickness check
  • Magnetic particle (MT) examination (dry, wet or fluorescent)
  • Ultrasonic Test (UT) examination

DESTRUCTIVE TESTS CONDUCTED BY NITON VALVES:

  • Mechanical tests, hardness test and impact test up to -196°C
  • Micro-examinations by electronic microscope up to 500 times magnification
  • Macro-examinations
  • Ferrite check according to E562
  • Chemical analysis from CS Super Alloys, using spectrometer
  • Check analysis, C&S using induction analyser
  • Corrosion tests (eg IGC)
  • Step cooling test for alloy steel material [F22]

This target is met through selected top quality and reliable sub-suppliers in the Indian market and through qualified and upgraded NDE operators, skilled Quality Control inspectors, Quality Control professional and experienced technicians.

Moreover, an integrated combination and optimization of controls at manufacturers, sub-suppliers and in process inspections, examinations and final pressure tests (conventional and special tests), assure valves of the highest grade complying with the most severe technical and contractual requirements.

Again, a wide selection of the latest generation inspection and test equipment permits Niton Valve Industries to guarantee the highest Quality Control levels, control processes capability and the final product's quality.
