Bosega Pipes and Tubes stands out as a top-notch manufacturer and supplier of Hastelloy EFW Pipes right in Cape Town, South Africa. They provide high-quality piping solutions that are specifically designed to resist corrosion, boast strength, and ensure durability even in the toughest environments. Hastelloy, which is a nickel-molybdenum-chromium alloy, is crafted to excel in both oxidizing and reducing conditions, making it a perfect fit for industries like chemical processing, marine applications, and power generation.
These Hastelloy EFW Pipes mainly consist of nickel (about 58%), molybdenum (up to 30%), and chromium (up to 23%), with some variations including iron, tungsten, and cobalt depending on the specific grade, such as Hastelloy C22, C276, or B2. This unique blend gives them outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking. On the mechanical side, these pipes deliver high tensile and yield strength, excellent ductility, and great weldability, ensuring they maintain stability and performance even in extreme chemical and thermal conditions.
