ਸਟੀਲ ਫਲੈਂਜ ਸਮੱਗਰੀ ਗਾਈਡ: ਕਾਰਬਨ, ਸਟੇਨਲੈੱਸ ਅਤੇ ਐਲੋਏ ਦੀ ਚੋਣ

Choosing the Right Flange Material

Material selection is critical. Wrong choice leads to premature failure, corrosion, and safety incidents.

ਕਾਰਬਨ ਸਟੀਲ ਫਲੈਂਜ

ASTM A105

Industry workhorse for general service.

• Applications: Oil/gas pipelines, petrochemical, power generation
• Temperature: -20F to 800F
• Tensile: 70,000 psi min

ASTM A350 LF2

Low-temperature with Charpy testing.

• Applications: LNG, cryogenic, cold climate
• Temperature: -50F to 800F

ਸਟੇਨਲੈੱਸ ਸਟੀਲ ਫਲੈਂਜ

304/304L (F304/F304L)

• Applications: Food/beverage, pharmaceutical, chemical
• ਸ਼ਾਨਦਾਰ ਆਮ ਖੋਰ ਪ੍ਰਤੀਰੋਧ

316/316L (F316/F316L)

• Applications: Offshore, seawater, marine
• Superior chloride resistance (2-3% Moly)

ਮਿਸ਼ਰਤ ਸਟੀਲ ਫਲੈਂਜ

Chrome-Moly (F11, F22, F91)

• F11: Up to 1000F, steam lines
• F22: Up to 1100F, high-pressure steam

• Nickel Alloys: Inconel, Hastelloy for extreme corrosion

Selection Factors

1. Process fluid corrosivity
2. Operating temperature/pressure
3. Environment (coastal, industrial)
4. Design life and total cost
