Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of Stainless Steel 347 / 347H Capillary Tubes, renowned for delivering high-quality stainless steel products worldwide. These capillary tubes are widely used in precision instruments, medical equipment, and industrial applications due to their excellent resistance to intergranular corrosion and high-temperature environments.
SS 347 is stabilized by the addition of columbium (niobium), making it resistant to chromium carbide precipitation, a common issue in high-temperature service. SS 347H is a high carbon version of 347, offering enhanced creep resistance and higher strength at elevated temperatures. These properties make them ideal for applications in heat exchangers, nuclear reactors, oil refineries, and power plants.
Sumer Metal Industries has built a strong global presence, exporting its 347 / 347H stainless steel capillary tubes to key international markets including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and various regions across Africa. The company adheres to international standards and delivers products that meet the stringent requirements of global industries.
The capillary tubes are manufactured using state-of-the-art machinery and strict quality control procedures, ensuring tight dimensional tolerances, smooth surface finishes, and superior performance under extreme conditions. They are available in different sizes, thicknesses, and customized lengths based on client requirements.
