1.  SIX MOST COMMON TYPES NICKEL ALLOY FLANGE Hastelloy C2000 USED IN THE OIL AND GAS INDUSTRY

Weld-neck

Complete with a tapered hub, these flanges are recognisable and used in high pressure environments. The flange is particularly useful under repeat bending conditions.

Slip-on

A flange which is slipped over the pipe and welded both inside and outside to increase strength and prevent leakage. A favourite for engineers compared to the weld-neck due to their lower cost.

Lap-joint

Used in conjunction with a lap joint stub end, the flange is slipped over the pipe but not fastened, unlike the slip-on. Instead the flange is held in place by the pressure transmitted to the gasket by the flange pressure against the back of the pipe lap.

Threaded

Used in special circumstances, the threaded flange can be attached to the pipe without being welded. These are usually positioned on pipes with a deep wall thickness, used to create the internal thread.

Blind

Manufactured without a bore, these flanges are used to blank off the end of piping, valves and pressure vessel openings. They are also most suitable for high pressure temperature applications.

Socket-weld

With a static strength equal to the Slip-on flange, the Socket-weld is connected with the pipe with 1 fillet weld on the outside of the flange. Due to corrosion issues, some processes do not allow this flange.

3. Hastelloy C2000 material introduction:
 
 
HASTELLOY C2000
Hastelloy C2000 alloy, UNS N06200, is a corrosion resistant alloy with excellent resistance to uniform corrosion in oxidizing or re-ducing environments. Due to the addition of copper and the high content of chromium, it has enhanced corrosion resistance to sulfuric acid and process streams contaminated with ferric ions. In addition it has excellent resistance to stress corrosion cracking and superior resistance to localized corrosion as compared to C-276 alloy. This alloy has limited availability and can be made into sizes only 1/2" and greater is size for fasteners.
