Ten checks between raw material and dispatch
Product quality is controlled through defined manufacturing inspections and testing at different stages of production.
- Step 01Raw Material Inspection
Verification of material grade, chemical composition and mechanical properties
- Step 02Dimensional Inspection
Checking outer diameter, length, wall thickness and other critical dimensions
- Step 03Hardness Test
Verification of material hardness
- Step 04Ultrasonic Testing (UT)
Inspection for internal material discontinuities and thickness measurement, as applicable
- Step 05Heat Treatment Verification
Monitoring and verification of heat-treatment parameters
- Step 06Hydrostatic Test (HST)
Verification of cylinder strength and pressure integrity as per applicable requirements
- Step 07Air Leakage Test (ALT)
Checking for leakage under the specified test conditions
- Step 08Visual Inspection
Checking surface condition, forming defects, cracks and other visible defects
- Step 09Mechanical Testing
Verification of tensile strength, yield strength, elongation and impact properties, as applicable
- Step 10Final Inspection
Verification of dimensions, marking, appearance and required test records before dispatch
