Product Introduction

Stainless steel welded round pipe with smooth welds, polished surfaces, and corrosion resistance for fluid transport, equipment piping, and industrial pipeline systems.

 

Key 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.
