Kobs India is one of India’s leading manufacturers of high quality EFW (Electric Fusion Welded) Tubes which find application across diverse sectors. These Stainless Steel EFW pipes and tubes consigns to an electron beam welding, and the usage of high-speed movement of the electron beam focussed blow kinetic energy is transformed to heat the work piece so that the work piece leaving the liquefy, the development of the weld. We supply these Carbon Steel EFW Pipes to the following industries on a worldwide scale: Gas Industry, Oil Industry, Offshore Industry, Filtration Industry, Refining Industry, Refrigeration Industry, Petrochemical Industry, and more.
Our Alloy Steel EFW Pipes can be offered in made to order length sizes and shapes, and are available at market leading prices. These pipes and tubes can also be fabricated and machined to meet up the piping needs of our clients.
