Product Features

• Made by integral piercing and hot rolling with no weld seam, providing strong pressure resistance.
• 304/316 stainless steel resists acid, alkali, and salt-spray corrosion.
• Uniform wall thickness and smooth inner wall reduce scaling during media transfer.
• High pressure and burst resistance make it suitable for high-pressure fluid and high-temperature conditions.
