- About Us
Anchoring Industrial Growth Since 2004
We have been in the steel manufacturing industry since 2004. In 2013, we started a dedicated unit in Ahmedabad to manufacture seamless tubes and pipes. From the beginning, we have believed that quality has no trade-offs; our products can compete anywhere in the world. We strictly use Indian-sourced raw materials made from round bars that are tested at certified labs.
- Make in India, Supplying Globally - 100% sourcing of mother hollows from tested round bars.
- Integrated Manufacturing - From piercing to cold pilgering, cold drawing, heat treatment, finishing, and quality inspection everything happens in a single, integrated facility.
- Quality Backed by Certification - We have an in-house NABL-accredited lab that handles all testing - mechanical, chemical, NDT, and metallurgical.

We have a fully equipped lab of testing tools: Universal Testing Machine (UTM), Spectrometer, Positive Material Identification (PMI), Eddy Current Testing, Ultrasonic Testing, Intergranular Corrosion (IGC) Testing, Hydro Testing, Hardness Testing, Borescope Inspection
Certified
Quality
We hold certifications including ISO 9001, ISO 14001, ISO 45001, OHSAS 45001, and PED 2014/68/EU, along with TÜV Nord approval (AD 2000). We’re also an approved manufacturer for EIL.
Global
Reach
We export our products globally; leading names including ADNOC, LR Marine, and many other international inspection agencies approve them.
Make In
India
To reduce reliance on imports, we source 100% of our mother hollows locally, using NABL-tested round bars.
Environmental Responsibility
We put the environment first through eco-friendly practices, including solar panels, an ETP (Effluent Treatment Plant) for wastewater management, and acid scrubber systems to control fumes, all backed by ISO 14001 certification.

- Our Manufacturing Process
Reshaping the Steel Narrative With Advanced Capabilities
In India and across global markets, ASR is well-positioned for sustained growth in the steel industry, supported by robust domestic demand, large-scale infrastructure investments, and favourable policy support.
- 15) ASR - Leading Stainless Steel Seamless Pipe & Tube Manufacturer
Accredited In-House Testing Laboratory
ASR is ISO/IEC 17025 compliant; every test is conducted in-house for full traceability and control- from raw material to dispatch.
- Testing & Quality Control
Thorough Testing at Every Stage with a Leading Stainless steel Seamless Pipe & Tube Manufacturer in India
We are stainless steel seamless pipe & tube manufacturers in India, keeping quality as our top priority throughout the entire process, lowering the chance of failures and boosting client satisfaction.
Mechanical Testing
We conduct in-house mechanical testing on our final products using a 60-ton UTM (Universal Testing Machine), along with tests for hardness, bend, fatigue, and flattening. All tests follow ASTM, ASME, and EN standards under the specified environmental conditions.
Chemical
Analysis
Our OES spectrometer and PMI (Positive Material Identification) tools verify the exact composition and grade of every material to ensure 100% traceability. This test helps us ensure safety, prevent corrosion, and confirm the final product matches industry rules.
Non-Destructive Testing (NDT)
We evaluate the structural integrity, and material soundness of the pipes without altering or damaging their future usefulness. Our NDT processes help prevent catastrophic failure, leaks, or ruptures with our Non-Destructive Testing (NDT) quality process.
Pressure & Leak Testing
To maintain the integrity and safety of pressure equipment, we conduct a non-destructive examination. This assessment verifies that any new, altered, or repaired piping system can safely endure and remains leak-proof. We conduct hydrostatic and pneumatic pressure tests in accordance with ASTM and ASME standards.
Metallurgical Testing
We characterise the physical, chemical, and mechanical properties of the metal to discover if they will perform as needed in your particular industry. Gain access to a comprehensive report of findings and suggested actions. We also conduct microstructure and grain-size analysis.
Dimensional Inspection
Dimensional inspection of stainless steel pipes verifies that physical geometry matches engineering drawings and governing standards, primarily ASME B36.19M and ASTM A312. Key Inspection Parameters: Outside Diameter (OD), Wall Thickness, Length & Straightness, Ovality (Out-of-Roundness), End Condition & Squareness, and Weight.
