Frequently Asked Questions

Everything you need to know about our in-house manufacturing processes, international certifications, metallurgical testing, and global export procedures.

Starlight Tubes operates a dedicated in-house manufacturing facility in Mumbai, India equipped with cold pilger mills, draw benches, and annealing furnaces. We maintain complete control over raw material sourcing, manufacturing tolerances, and quality inspection.
All our pipes, tubes, and fittings are manufactured strictly in accordance with ASTM (A312, A269, A213, A106, A53, A333), ASME (SA312, SA213), API (5L PSL1/PSL2), and EN/DIN standards. We provide Mill Test Certificates (MTC) conforming to EN 10204 Type 3.1 and can arrange Third-Party Inspection (TPI) by TUV, DNV, Lloyd's, or Bureau Veritas for 3.2 certification.
Our manufacturing specialty includes austenitic stainless steels (SS 304, 304L, 316, 316L, 321, 310S, 347H), high-performance grades (904L, 254 SMO), duplex & super duplex (UNS S31803 / S32205, UNS S32750), as well as nickel alloys (Inconel 600, 625, Monel 400, Hastelloy C276).
Standard testing includes 100% Hydrostatic Pressure Testing (up to 500 Bar), Eddy Current Testing, Ultrasonic Flaw Detection, XRF Spectrometry (Positive Material Identification - PMI), Tensile & Flattening tests, Flare tests, and Intergranular Corrosion Testing (ASTM A262 Practice E).
Export orders are packaged in ISPM-15 heat-treated seaworthy wooden boxes or heavy steel-strapped hexagonal bundles. All tube ends are protected with heavy-duty plastic caps, and materials are wrapped with Vapor Corrosion Inhibitor (VCI) waterproof sheeting to prevent rust and oxidation during ocean transit.
We ship directly out of Nhava Sheva (JNPT) and Mumbai Port to over 60 countries across the Americas, GCC / Middle East, Europe, and Asia-Pacific. Standard inventory items dispatch within 48-72 hours, while custom cold-drawn or specialized schedules typically have a 2-4 week production cycle.
You can email your technical specifications and quantity requirements directly to sales@starlighttubes.com or use our website inquiry form. Our commercial and metallurgical team responds with formal quotations and technical compliance sheets within 24 hours.
