Manufacturing Facility – Copper Tubes Test

We would like to introduce ourselves as RR Shramik (Ram Ratna Wires Limited) – a part of the USD 1.6 Billion RR Global conglomerate, with a presence in more than 90 countries and group brands like RR Kabel, RR Shramik, RR Parkon, and many more.

We manufacture Copper Seamless Tubes – Grade DHP (De-oxidized High Residual Phosphorus Copper) at two advanced production facilities:

• Vadodara, Gujarat – with an installed capacity of 12,000 MTPA
• Bhiwadi, Rajasthan – with an installed capacity of 36,000 MTPA

Both plants are equipped with state-of-the-art Cast and Roll Technology, incorporating advanced processes such as Online Eddy Current Testing and Annealing (both inside and out) to ensure the highest quality standards.

Our products conform to international norms and are designed for easy bending, expansion, swaging, brazing, and soldering.

Our copper tubes comply with all major international standards such as IS 10773, IS 2501, JIS H3300, ASTM B68, B75, B280, B287 1-2, E243, EN 12735-1, and AS/NZS 1571, and are widely used across industries including ACR, HVAC, VRV/VRF systems, heat exchangers, condenser coils, medical gas piping, plumbing, and construction projects.
