fact, its worth spending time on highly-credible platforms to ensure you’re utilizing/investing
your money in right direction for the growth of your organization.
Manufacturers of Super Duplex Steel Pipe Fittings combine their all efforts, time & sweat to produce products according to the national & international quality standards to meet all needs of each industry & help them grow with planet-saving solutions.
Duplex Steel v/s Super Duplex Steel Pipe Fittings
Super Duplex Steel consists of 25-28% chromium, while
duplex steel consists of 22% chromium. Higher the chromium content, the higher
is level of pitting corrosion resistance. Both exhibits better toughness &
ductility.
Super Duplex Steel V/S Stainless Steel
The main difference between stainless steel & super
duplex steel is in composition. Super duplex steel contains more 25-28%
chromium, up to 5% higher molybdenum, up to 9% nickel, & up to 0.05–0.50%
nitrogen.
This difference in composition makes super duplex steel offer higher chloride stress corrosion resistance & pitting & cracking corrosion resistance. It is an austenitic-ferritic iron, chromium, nickel alloy with an addition of molybdenum, & is more durable & twice stronger stainless steel.
Types of Super Duplex Steel Pipe Fittings
The types include seamless, fabricated & welded pipe
fittings. For example: Elbow (short & long radius), reducing elbow,
fabricated tea, reducer, concentric reducer, eccentric reducer, stub ends,
cross, reducing cross, tees, couplings, 5D elbow, pipe nipples etc.
Features & Properties
- Impact resistance: Super Duplex Steel Pipe Fittings are extremely resistant to corrosion, intergranular corrosion, chloride corrosion, stress corrosion, pitting & cracking.
- Temperature: Due to high chromium content, it has the ability to withstand over 300°C.
- Machinability & weldability
- High tensile strength
- Highly durable than other types of stainless steel
Applications
Due to increased yield strength & resistance to chloride
stress corrosion & pitting corrosion, Super Duplex Steel Pipe Fittings find
their usage in wide applications, including offshore platforms, boilers,
pressure vessels, chemical & petrochemical process, oil & gas industry,
heat exchangers etc.
It has the ability to withstand high temperature & other temperature variations. It has 38 to 45 range PREn (Pitting Resistance Equivalency number).
