Our Commitment to Zero-Defect Engineering
At Trisha Fittings, quality is not an afterthought; it is ingrained into our manufacturing DNA. Because our products are trusted in sterile applications across pharmaceutical WFI loops, biotech fermenters, and aseptic dairy pipelines, even a microscopic flaw is intolerable.
That is why every single stainless steel tube and fitting undergoes a comprehensive 14-point testing protocol before leaving our plant. From raw material spectroscopic validation to internal optical profilometer roughness verification, complete batch compliance is guaranteed.
The 14-Step Quality Assurance Process
Stringent destructive and non-destructive testing performed at every stage of the manufacturing cycle.
Chemical Composition Analysis
Verifying raw material composition using Optical Emission Spectrometers.
Tensile & Yield Test
Evaluating ultimate tensile strength and ductility of the steel under mechanical strain.
Hardness Testing
Measuring Rockwell & Brinell hardness to verify proper heat treatment.
Flattening Test
Testing tube ductility, cold-formability, and weld seam integrity.
Flaring & Expansion Test
Assessing the ability of the tube to be expanded without micro-cracking.
Hydrostatic Pressure Test
Pressurizing tubes with water up to 100% test pressure to check structural integrity.
Eddy Current Inspection
Continuous in-line non-destructive testing to detect sub-surface material flaws.
Ultrasonic Flaw Detection
Using high-frequency sound waves to verify internal acoustic homogeneity.
Surface Roughness (Ra Value)
Measuring internal Ra values with diamond profilometers (guaranteed Ra ≤ 0.4 µm).
Intergranular Corrosion (IGC)
Testing resistance to localized intergranular attack according to ASTM A262.
Dimensional Tolerancing
Precision checks for OD, ID, wall thickness, ovality, and straightness.
Microstructure Metallography
Examining grain boundary structure of the austenitic steel under high-magnification.
Visual & Boroscopic Inspection
Detailed optical probe check for surface scratches, pits, and weld seams.
Positive Material Identification (PMI)
100% XRF spectrometer alloy verification to ensure certified SS 304/316L grades.
