B564 N04400 Weld Neck Raised Face Nickel Copper Alloy Flange for
Mining Industry
Monel 400 weld-neck flanges are a nickel-copper alloy (approx. 67% nickel - 23% copper) that
is resistant to high-temperature seawater and steam, as well as
salt and corrosive solutions. Alloy 400 is a solid solution alloy
that can only be hardened by cold working. This nickel alloy has
good corrosion resistance, weldability and high strength. It has a
low corrosion rate in fast-flowing brackish or seawater, excellent
resistance to stress corrosion cracking in most freshwaters, and is
also resistant to a wide range of corrosive conditions, making it
widely used in marine and other non-oxidizing chloride solutions.
This nickel alloy is particularly resistant to hydrochloric and
hydrofluoric acids after degassing. Due to the high copper content,
Alloy 400 is quickly attacked by nitric acid and ammonia systems.

Weld Neck Flanges
Weld Neck Flanges are a very common type of pipe flanges used in
various industrial applications. They have a long tapered hub and
are often used for high pressure applications.
We are a fast growing organization, engaged in manufacturing,
supply and export of welding neck flanges, industrial weld neck
flanges and forged flanges. Our weld neck flanges are drilled with
the wall thickness of flange having the same dimensions of pipe.
Flanges for heavier pipes have smaller bore, while flanges of
lighter pipes have larger bore. These weld neck flanges, industrial
weld neck flanges, forged flanges are normally used for
high-pressure, cold or hot temperature. |
