Rashdan Pipes and Tubes in Amman, Jordan, supplies seamless pipes built for industries that refuse to compromise on strength and stability. Their Stainless Steel 347 and 347H Seamless Pipes are engineered to handle high temperatures, aggressive chemicals, and demanding operating conditions. With exceptional durability and a smooth, consistent finish, these pipes deliver long-term performance where reliability is non-negotiable. Rashdan’s strict quality checks and precision manufacturing ensure every pipe meets global expectations. Companies trust these pipes for their heat resistance, structural integrity, and ability to stay strong even during prolonged, high-intensity industrial operations.
Stainless Steel 347 and 347H contain chromium, nickel, and niobium, which enhances stabilization against carbide precipitation during high-temperature exposure. 347H has a higher carbon content, giving it greater strength at elevated temperatures. Both alloys offer strong tensile and yield properties, solid creep resistance, and dependable mechanical stability during thermal cycling. The seamless construction boosts pressure resistance and ensures smooth, uninterrupted flow. These alloys maintain toughness while resisting oxidation and corrosion, making them ideal for continuous high-heat applications.
