If you are looking for stainless steel tubing suitable for high-temperature, high-pressure, and harsh operating conditions, we offer ASME SA 312 304H pickled tubing, specifically designed for industrial hydraulic cylinders, engineering equipment, and high-temperature fluid transport systems.
GNEE is a manufacturer and supplier of 304H stainless steel tubing. We offer a wide range of 304H stainless steel tubing, including ASTM A312 TP 304H seamless tubing and 304H resistance-welded (ERW) tubing, as well as various pipe profiles. Our 304H stainless steel tubing is widely used in components of oil refineries, the natural gas industry, pressure vessels, heat exchangers, boilers, and thermal power plants.
Our 304H seamless tubing is a high-strength tubing with a higher carbon content, exhibiting superior strength, creep resistance, and structural stability at high temperatures. It is produced through hot extrusion from steel billets and undergoes a pickling process for a smoother, cleaner, and more aesthetically pleasing finish, commonly used in the chemical, oil refining, and power generation industries. 304H stainless steel ERW tubing can be welded with filler material to minimize intergranular corrosion during the welding process, making it suitable for condensers and other applications requiring high strength.
