Strategically located in the bustling industrial landscape of Kinshasa, Congo, Wissa Pipes has built a strong reputation for reliability and exceptional quality. We are your trusted partner for demanding industrial components, specializing in high-performance materials like Stainless Steel 347/347H Heat Exchanger Tubing. Our commitment is to supply Congolese industries with tubing that not only meets but exceeds the rigorous demands of modern heat exchange applications, ensuring optimal efficiency and long-lasting performance in even the most challenging environments.
The strength of our 347/347H tubing lies in its specialized composition, which is stabilized with columbium to provide outstanding resistance to intergranular corrosion following exposure to high temperatures. This crucial feature ensures the material maintains its integrity and performance. The “H” grade variant is specifically processed to achieve higher tensile and yield strengths at elevated temperatures, making it exceptionally durable and reliable for high-pressure systems where standard materials might falter under sustained stress.
