Rithav Pipes and Tubes, based in Delhi, India, is a well-respected manufacturer and supplier of Hastelloy EFW (Electric Fusion Welded) Pipes, designed to meet the rigorous demands of corrosive and high-temperature industrial settings. Crafted from top-quality Hastelloy alloys like C-22, C-276, and C-2000, these pipes offer remarkable resistance to a variety of aggressive chemicals, including strong oxidizers, acids, and environments rich in chlorides. Utilizing cutting-edge welding and testing technology, Rithav’s EFW pipes guarantee excellent dimensional accuracy, weld integrity, and mechanical performance, making them perfect for sectors like chemical processing, marine, energy, and pollution control.
Hastelloy EFW Pipes are constructed from high-performance nickel-based alloys, generally comprising nickel (≥57%), molybdenum (15–17%), chromium (14–16%), along with trace elements of iron, cobalt, tungsten, and carbon. This unique composition provides exceptional resistance to pitting, crevice corrosion, and both oxidizing and reducing environments. Their mechanical properties include a tensile strength of ≥690 MPa, yield strength of ≥310 MPa, and elongation of ≥30%, depending on the specific grade. These pipes maintain their structural integrity even under high temperatures and corrosive conditions, making them ideal for pressure-containing components and high-stress applications across various industries.
