Introducing the first 2205 duplex stainless steel buttweld fittings manufacturer in India, know its applications

Are duplex 2205 fittings suitable for high-pressure uses?

Duplex 2205 pipe fittings are suitable for high pressure uses across industries like oil & gas, chemical processing, etc.

  • The material has a high tensile strength which allows it to withstand the stress associated with different high pressure services.
  • Duplex 2205 is resistant to different forms of corrosion, like pitting and crevice. They can also withstand high pressure services in the presence of corrosive fluids.
  • The saf 2205 concentric reducers and other fittings are available in different pressure ratings, and there are ratings as well to accommodate the increased pressure ones.

However, the exact amount of pressure that a given fitting can withstand will depend on the type, wall thickness & size of the fittings along with the temperature conditions.

Which tests are carried out on 2205 duplex stainless steel buttweld fittings?
  • Chemical composition analysis on 2205 duplex stainless steel buttweld fittings verifies the material composition and ensures it adheres to specific requirements.
  • Mechanical tests are designed to verify the mechanical properties of duplex steel 2205 stub end, like tensile strength, hardness, etc.
  • Impact testing assesses the resistance of 2205 material to brittle fracture, especially at low temperatures.
  • Non destructive tests are designed to detect surface and sub surface defects and irregularities.
  • Pressure tests help detect any kind of leakages in the ASTM A815 UNS S32205 pipe bend.

Are alloy 2205 elbows more expensive? why ?
  • ASTM A815 alloy 2205 elbow are more expensive than standard stainless steel grades. This is primarily due to its chemical composition. The material contains alloying elements like nickel, chromium and molybdenum which increases the prices.
  • Due to the alloying elements, the elbow shows properties like high corrosion resistance, strength, etc., which also contributes to a higher price.
  • The material offers superior resistance to corrosion, especially in harsh chloride containing environments. This property can justify its high price.
  • This type of duplex steel 2205 seamless fittings can be more complex to manufacture than the standard stainless steel grades. The use of specialized process and equipment can also lead to a price rise.
What distinguishes super duplex 2507 fittings from duplex 2205 fittings?
  • 2507 has 28% chromium, 7% nickel, 4% molybdenum and 0.27-0.32% nitrogen in its chemical composition. Whereas, UNS S31803 pipe cross material has 22% chromium, 5-6% nickel, 3% molybdenum and 0.15-0.20% nitrogen.
  • 2507 offers higher corrosion resistance properties than 2205, especially in various aggressive environments.
  • 2507 exhibits greater mechanical properties.
  • 2205 WNR 1.4462 welded fittings are more cost-effective.
What are some things to think about while choosing a duplex 2205 stainless steel tee?
  • Analyze your operating condition and ensure the duplex 2205 stainless steel tee is capable of withstanding that, including pressure and temperature.
  • The size and diameter of the tee should match your system requirements.
  • Choose the right connection type for UNS S32205 equal tee and ensure it aligns with your system design and installation requirements.
  • Always work with a reputed manufacturer like Regent Steel & Engineering Co., who offers quality duplex 2205 reducing tee at competitive prices.
