Lathief Pipes, your trusted manufacturing partner in Safat, Kuwait, takes pride in supplying high-performance materials tailored for demanding environments. Our Stainless Steel 347/347H Seamless Tubing is a prime example, engineered to offer exceptional reliability. We understand that in critical applications, there is no room for compromise, which is why we provide tubing that delivers superior strength and corrosion resistance, ensuring your projects are built on a foundation of unwavering quality and long-term durability.
The strength of this tubing comes from its specific composition, which is stabilized with columbium. This key addition makes it highly resistant to intergranular corrosion following exposure to high temperatures. The result is a material that maintains excellent mechanical properties, including strong tensile strength and good creep resistance, even under intense thermal cycling and prolonged heat, making it a robust choice for challenging conditions.
