Product Features

• Formed by welding rolled plate, with a flat weld seam and smooth internal and external polished surfaces.
• 304/316 stainless steel resists acid, alkali, and seawater corrosion without rusting.
• Standard roundness and uniform wall thickness reduce fluid conveying resistance.
• The pipe can be cut, bent, and welded with flanges to match various pipe fittings.
