Stainless Steel Concentric Increaser

This fitting provides a concentric transition between a 50 mm and 110 mm diameter pipe, keeping both centrelines aligned throughout the connection. The symmetrical cone profile ensures smooth, consistent flow with no offset between pipe centres.

Manufactured from AISI 316L stainless steel (EN 1.4404), this is a low-carbon, molybdenum-bearing grade offering strong resistance to corrosion, chlorides, and a broad range of chemicals. It performs reliably across hygienic, clean-process, and industrially demanding environments, and is well suited to welded pipework assemblies.

Applications:

• Food and beverage — dairy processing, breweries, distilleries, soft drink production
• Pharmaceutical — purified water systems, CIP/SIP pipework, clean-process installations
• Water and wastewater — treatment plants, chemical dosing systems
• Chemical processing — corrosive liquid transfer, process piping
• Marine and offshore — salt-laden environments, corrosion resistant pipe systems
• General industrial — process plants, pump and equipment connections
