Samia Pipes and Tubes is a well-respected manufacturer and supplier located in Tunis, Tunisia, specializing in high-quality Super Duplex Steel Instrumentation Tubing designed for tough industrial applications. The company prides itself on delivering precision-engineered products that adhere to international quality standards and meet the specific needs of its clients. With state-of-the-art manufacturing facilities and rigorous quality control measures, Samia Pipes and Tubes guarantees exceptional performance, durability, and reliability in every item they produce. Their customer-centric approach, technical know-how, and consistent supply capabilities have established them as a trusted partner for industries that require high-strength and corrosion-resistant instrumentation tubing.
Super Duplex Steel Instrumentation Tubing boasts a unique dual-phase microstructure, combining austenitic and ferritic properties, thanks to a carefully balanced chemical composition that includes chromium, molybdenum, and nitrogen. This well-structured design offers remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, the tubing delivers high tensile and yield strength, outstanding fatigue resistance, and solid toughness. Its strength is nearly double that of standard austenitic stainless steels, allowing for thinner wall designs while still performing well in high-pressure and high-temperature situations.
