Titanium Stub End Manufacturer in Chennai
Nobel Weld is a titanium stub end manufacturer in Chennai. We supply and machine lap joint stub ends to MSS SP-43 and ASME B16.9 in titanium Grade 2, zirconium, 310MoLN, duplex and copper-nickel, with carbon steel or stainless backing flanges.
A stub end with a loose backing flange puts the costly alloy only where the fluid touches it. That makes titanium piping far cheaper than solid titanium flanges.

FAQ
Stub ends: common questions
What does your titanium stub end manufacturing include?
Short and long pattern lap joint stub ends to MSS SP-43 and ASME B16.9, with backing flanges.
Why use a stub end instead of a solid titanium flange?
Only the stub end touches the fluid, so the backing flange can be carbon or stainless steel. It costs far less than a solid titanium flange.
Can you supply the backing flanges?
Yes, to ASME B16.5 in carbon steel, stainless or coated steel.
