Samia Pipes, a top-notch manufacturer and supplier located in Tunis, Tunisia, focuses on crafting high-quality Hastelloy Welded Pipes that excel in the toughest and most corrosive industrial settings. With a strong dedication to precision engineering, adherence to international standards, and a passion for customer satisfaction, Samia Pipes provides durable and dependable piping solutions for various industries, including chemical processing, pharmaceuticals, marine, and power generation. Known for their remarkable resistance to a wide array of corrosive substances, including potent oxidizers and reducing agents, Hastelloy Welded Pipes from Samia Pipes guarantee consistent weld quality, precise dimensions, and long-lasting performance even in critical applications and harsh operating conditions.
Hastelloy Welded Pipes are generally crafted from alloys like Hastelloy C-22, C-276, or C-2000. These alloys typically consist of about 55–61% nickel, 14.5–22% chromium, and 13–17% molybdenum, along with some iron, cobalt, tungsten, and trace elements. This unique blend provides outstanding resistance to both oxidizing and reducing chemicals. The welded pipes boast impressive tensile strength (up to 790 MPa), yield strength around 350 MPa, and exceptional ductility and fatigue resistance. Thanks to advanced welding techniques, they ensure structural integrity, corrosion resistance at the weld zones, and are well-suited for high-temperature and high-pressure service environments.
