Invar Pipe
What is Invar Pipe ?
Invar pipe is made from a nickel-iron alloy known for its very low expansion under heat. It’s mostly used in areas where size must stay stable across temperature changes. Parag Metals supplies Invar steel pipes in various grades invar 36, invar 42 and invar 49. These grades differ by their nickel content and performance needs.
We offer invar pipes in various sizes and forms to match different uses. Pipes range from 1/8” to 6” in outer diameter and are available in both seamless and welded types.Invar 36 pipe is the most preferred, whereas Invar 42 and 49 are for extreme temperatures or magnetic requirements. These invar alloy tube are provided with a smooth surface and can be shaped easily. We also accept customized size orders as per requirement.
