Samia Pipes and Tubes is a trusted manufacturer and supplier of Hastelloy Boiler Tubing, based in Tunis, Tunisia. Engineered for extreme heat and high-pressure service, this tubing is designed to survive where ordinary materials fail. Using premium Hastelloy alloys, precision manufacturing, and rigorous quality control, Samia Pipes and Tubes delivers boiler tubing that maintains strength, integrity, and performance under continuous thermal stress. Known for technical reliability and consistent quality, the company supports power generation and industrial systems that demand endurance, safety, and long service life.
Hastelloy Boiler Tubing is generally crafted from corrosion-resistant alloys such as Hastelloy C-276 or C-22. These alloys typically consist of about 55–61% nickel, 14.5–22% chromium, and 15–17% molybdenum, along with iron, cobalt, tungsten, and trace elements. This unique composition offers remarkable resistance to both oxidizing and reducing environments, particularly in high-temperature steam systems. The mechanical properties include a tensile strength of up to 790 MPa, a yield strength of around 350 MPa, and impressive ductility and fatigue resistance. The tubing retains its structural integrity even under high thermal stress and corrosive conditions, making it ideal for long-term use in boiler and high-pressure steam applications.

Hastelloy Boiler Tubing is a go-to choice in industries that require exceptional resistance to heat, pressure, and harsh chemicals. In power generation facilities, you’ll find it in high-pressure boilers, superheaters, and heat exchangers, thanks to its ability to handle high temperatures and corrosive flue gases. The chemical and petrochemical sectors rely on it for steam-generating systems that deal with acidic or chloride-heavy environments. It’s also perfect for marine and offshore applications, especially in steam and condensate systems that come into contact with seawater. With its outstanding resistance to pitting, stress corrosion cracking, and thermal fatigue, Hastelloy tubing is crucial for ensuring long-term reliability in tough boiler conditions.
