Hastelloy C-2000 Slip On Flanges are forged nickel-chromium-molybdenum-copper alloy flanges made from UNS N06200 / W.Nr. 2.4675 material, typically supplied to ASTM B564 material requirements and ASME B16.5 dimensional standards in pressure classes 150# – 1500#. Ragnar Metals & Tubes manufactures and exports these flanges with RF / FF facing options, EN 10204 3.1/3.2 documentation, and third-party inspection on request.
Ragnar Metals & Tubes is a C-2000 Slip On Flange Supplier and manufacturer of Hastelloy C-2000 (UNS N06200) slip on flanges to ASTM B564 and applicable ASME flange dimensional standards, with common sizes and classes available from stock, subject to current inventory, for export and EPC orders.
A slip-on flange has a bore slightly larger than the pipe outside diameter, allowing it to slide over the pipe end before being fillet-welded on both the inside and outside faces. Slip-on flanges are easier to align and generally lower cost than weld neck flanges, though their fillet-weld joint is generally rated at a fraction of the fatigue strength of a full-penetration weld neck joint under cyclic loading.
Hastelloy C-2000 is a nickel-chromium-molybdenum-copper alloy (UNS N06200) known for a combination of chromium (for oxidizing media) and molybdenum-plus-copper (for reducing media) that gives resistance across an unusually wide range of chemical environments, including sulfuric acid.

The Middle East and Indian sub-continent are home to hundreds of metal suppliers ranging from small trading shops to large ISO-certified manufacturers. International buyers typically evaluate a supplier on quality compliance, production capability, export experience and pricing transparency before placing a bulk order.
Bore sized to slip over the pipe OD
Fillet-welded inside and outside for a double weld joint
Easier alignment than weld neck flanges
Lower material and labor cost than weld neck flanges
Common in low-to-moderate pressure piping
Manufactured from Hastelloy C-2000 (UNS N06200) for a combination of chromium (for oxidizing media) and molybdenum-plus-copper (for reducing media) that gives resistance across an unusually wide range of chemical environments
