ASTM A249 TP304 Stainless Steel Heat Exchanger Tube supplier

GNEE is a well-known manufacturer, supplier, and exporter of ASTM A249 TP304 steel pipe. Our ASTM A249 welded pipes are primarily used in boilers, heat exchangers, superheaters, and condensers. We can customize pipes of various shapes and sizes to meet specific customer requirements and supply them at highly competitive prices. We produce ASTM A249 pipes using flat rolled steel strips through argon arc welding and plasma welding processes.

Common sizes and wall thicknesses for ASTM A249 TP304 stainless steel pipes range from 1/8 inch (3.2 mm) inner diameter to 12 inches (304.8 mm) outer diameter, and from 0.015 inches to 0.320 inches (0.4 mm to 8.1 mm) wall thickness. Other sizes are also available. Wall thickness is categorized by average wall thickness (A.W) and minimum wall thickness (M.W), and thicker-walled pipes are also available.
