A piping system using ASTM A403 Pipe Fittings has many inherent advantages over other forms, Global International is a specialized WP Pipe Fittings Suppliers in India
• SS Butt weld Fittings:- Welding a SS fitting to the pipe means that it is permanently leak-proof.
• The continuous metal structure formed between Stainless Steel Pipe and Stainless Steel Fitting adds strength to the system.
• Smooth inner surface and gradual direction changes reduce pressure losses and turbulence and minimize the action of corrosion and erosion.
• A welded system utilizes a minimum of space.
