Quality is Our Priority

At Siddhgiri Overseas, quality is not just a process — it is our culture. Every product we manufacture and supply undergoes rigorous multi-stage quality checks from raw material procurement to final dispatch.

Our state-of-the-art testing laboratory is equipped with advanced instruments to perform chemical, mechanical, dimensional and non-destructive tests as per international standards.

  • ISO 9001:2015 Certified
  • 100% Material Traceability
  • Mill Test Certificates (MTC)
  • Third-Party Inspection
  • NACE MR0175 Compliant
  • PED 2014/68/EU Compliant

Our Quality Process

Every product passes through a strict 6-stage quality control process before it reaches you.

01

Raw Material Inspection

All incoming raw materials are inspected for chemical composition, mechanical properties and dimensional accuracy before production begins.

02

Chemical Analysis

Spectrometric analysis is performed to verify exact material grade and composition as per ASTM, ASME and EN standards.

03

Mechanical Testing

Tensile strength, yield strength, hardness (Brinell/Rockwell/Vickers) and impact (Charpy) tests are conducted as per applicable standards.

04

NDT Testing

Non-destructive tests including Ultrasonic Testing (UT), Radiography (RT), Magnetic Particle (MT) and Dye Penetrant (PT) are performed.

05

Dimensional Inspection

All products are dimensionally verified using calibrated instruments to ensure compliance with ASME B16, DIN and EN dimensional standards.

06

Final Inspection & Dispatch

Final visual inspection, marking, documentation and third-party certification before packing and dispatch to ensure zero defects.

Testing Methods

Our in-house laboratory is equipped to perform a wide range of destructive and non-destructive tests.

Spectrometric Analysis

PMI (Positive Material Identification) using OES spectrometer to verify exact chemical composition.

Tensile Testing

Universal Testing Machine (UTM) for tensile strength, yield strength and elongation as per ASTM A370.

Hardness Testing

Brinell, Rockwell and Vickers hardness testing to verify material hardness compliance.

Ultrasonic Testing (UT)

Detection of internal flaws, laminations and inclusions using ultrasonic pulse-echo technique.

Radiographic Testing (RT)

X-ray and gamma-ray radiography to detect internal weld defects and discontinuities.

Dye Penetrant Test (PT)

Surface crack detection using liquid penetrant inspection as per ASME Section V.

Magnetic Particle Test (MT)

Detection of surface and near-surface discontinuities in ferromagnetic materials.

Hydrostatic Testing

Pressure testing of pipes, fittings and valves to verify leak-tightness and pressure integrity.

Impact Testing (Charpy)

Charpy V-notch impact testing at sub-zero temperatures for low-temperature service applications.
