Quality Assurance









Quality Assurance and Inspection

The Quality Assurance programme encompasses the complete cycle from design to detail engineering, manufacturing installation and commissioning. A systemised procedure of “Quality Control” from raw material to finished product is rigorously maintained as per written procedure of Quality Assurance Plan.

INDURE fully recognises the need for an emphasis on quality and all its members strive achieve excellence in their designated work which has enabled it to gain recognition, reputation and regular clientele for its products.

INDURE is well equipped with testing facility to check the quality right from raw material to final inspection to monitor and control the design/required parameters at various stage of manufacturing:

  • Sand Test lab
  • Universal Testing Machine
  • Hardness Tester
  • Ultrasonic Machine
  • Spectrometer
  • Metallurgical testing
  • Hydro test
  • Vacuum test
  • DP Test

Inspection at Raw Material Stage

All raw materials supplied by qualified and approved suppliers are tested to maintain the required quality parameters like

  • Ultrasonic testing is done for all shafting material above 50mm diameter
  • Shore Hardness is checked for rubber Components
  • Silica Sand is tested for moisture ,clay and grain Size
  • Pig Iron is tested for % of Carbon and Silicon
  • Ferro Chrome is tested for % of Carbon , Silicon and Chrome
  • Mould paint density is checked
  • Viscosity is checked for Hardener and Binder solvents
  • Steel is tested as per various applicable Standards

Inspection during manufacturing (In process inspection )

  • Hardness is checked for every mould
  • Spectrometer analysis for chemical Composition is done for every heat before pouring
  • Pouring temperature is checked for every heat
  • Welder qualification is checked and verified from time to time as per ASTMA Section IX
  • DP Test is carried out at root run stage of weld Joints ( Butt Joint )
  • Procedure Qualification is carried out as per Welding Procedures
  • Visual inspection is carried out at knockout stage of castings
  • All Critical dimensions are checked during process as per drawing
  • Hydraulic testing is done for volute liners of pump as per requirement
  • Dynamic Balancing is done for Pump Impellers
  • All assemblies are checked during process as per documented procedures/check list

Final Inspection

  • Hardness testing is carried out of each heat after finishing the casting
  • Hydraulic testing is done for fittings for soundness of the casting
  • Free run test / No load run test is carried out for all rotating Assemblies like Rotary Feeder , Clinker Grinder
  • Dimensions check is carried out for each assembly/ components as per drawing
  • Pump performance test is carried out at in-house pump test bed to confirm the 100% compliance with stipulated technical specifications
