GNEE supplies ASTM A312 TP304 stainless steel welded pipes, an austenitic chromium-nickel stainless steel formed through tungsten inert gas welding (GTAW) or high-frequency resistance welding processes, and treated with bright annealing (BA) or acid pickling annealing. These pipes offer excellent corrosion resistance (against atmospheric conditions, rainwater, and common chemical media in farmland), good formability, and weldability, making them suitable for agricultural machinery components requiring both structural strength and weather resistance, such as spray system piping, irrigation valve connection tubes, and farm equipment support fluid conduits.

 

ASTM A312 grade TP304 pipes can be processed via hot rolling or cold rolling. These pipes are available in thicknesses ranging from 0.8 mm to 12 mm and come in various sizes and specifications to meet project requirements. A312 TP304 welded pipes are cost-effective and can be produced in sizes from 1/8 inch to 36 inches (NB). They are also suitable for pressure vessels-SA 312 TP 304 ERW pipes use longitudinal welded metal to precisely shape the pipes. These pipes are highly durable and can be welded in place without any filler material.
