1.4307 Stainless Steel Seamless ‘U’-Tubes (AISI 304L)
Manufacturers of EN 1.4307 / AISI 304L Stainless Steel Seamless ‘U’-Tubes for heat exchangers, condensers, boilers, and industrial applications requiring excellent corrosion resistance, weldability, and long service life.
1.4307 Stainless Steel Seamless ‘U’-Tubes (AISI 304L)
Our 1.4307 Stainless Steel Seamless ‘U’-Tubes, also known as
AISI 304L, are engineered for applications requiring excellent
corrosion resistance, reliability, and long service life. The low carbon content
of 1.4307 minimizes the risk of intergranular corrosion after welding, making these
tubes highly suitable for fabricated and welded heat transfer systems.
The seamless construction ensures superior mechanical strength and a smooth internal
surface that improves fluid flow efficiency and reduces pressure loss. The precision
‘U’-bend design enhances heat transfer performance while optimizing space utilization,
making these tubes ideal for heat exchangers, condensers, and evaporators.
Widely used in industries such as chemical processing, food & beverage, pharmaceuticals,
HVAC, and general industrial applications, 1.4307 Stainless Steel Seamless ‘U’-Tubes
offer excellent formability, weldability, and dependable performance under low to
moderate temperature and pressure conditions. Available in a wide range of sizes and
custom specifications, they provide a cost-effective and durable solution for demanding
thermal systems.
