Super duplex pipe
A super duplex tube refers to a type of pipe made from a SDSS alloy. A super duplex seamless pipe is a highly corrosion-resistant material that exhibits excellent strength and durability properties.
We are super duplex pipe supplier in Mumbai, the SDSS pipe entails a balanced microstructure consisting of both ferrite and austenite phases. This duplex microstructure contributes to the SD pipe’s exceptional mechanical and corrosion resistance properties in aggressive environments.

- Corrosion Resistance: These SD pipes exhibit excellent corrosion resistance, particularly in aggressive environments such as chloride-rich and alkaline conditions.
- Exceptional Strength: They possess excellent tensile and yield strength as compared to conventional duplex or austenitic stainless steel grades.
- Good Weldability: A SDSS pipe exhibit good weldability and allows easy fabrication and joining operations without any complexity.
- Cost-Effective Solution: Despite their excellent corrosion properties, SDSS pipes offer a cost-effective solution as compared to some other alloys in the market.
To assure the quality and avoid any future problems, we utilize dimensional checks on the super duplex seamless pipe

Calipers and micrometers are manual measurement tools employed to inspect and verify the outside dimensions of the SDSS welded pipe. Ultrasonic testing is commonly utilized to assess the wall thickness and other vital parameters of SDSS ERW pipes.
Eddy current testing is a non-destructive testing method that can be used to detect surface and near-surface defects in pipes. It employs electromagnetic induction to generate eddy currents.

- • Desalination: A SDSS exhaust pipe is employed in desalination plants and water treatment facilities.
- • Pulp and Paper Industry: SDSS pipes find usage in the pulp and paper industry, particularly in the chemical recovery and bleaching processes.
The pressure ratings for super duplex seamless pipes are influenced by many factors such as pipe dimensions and industry standards. The most commonly used design codes for determining pressure ratings of pipes are ASME B36.19 and APL 5L.
SDSS round pipe under ANSI/ASME B36.19 standard typically have pressure ratings ranging from 150 to 2500 psi or 1 MPa to 17 MPa. The pressure ratings for seamless pipes under API 5L standard range from 3,000 to 20,000 psi or 20 MPa to 138 MPa.
A SDSS square pipe offers several advantages due to its specific surface finish such as –
- The polishing process of SDSS pipes boosts the pipe’s corrosion resistance properties.
- The smooth and polished surface of SDSS pipes facilitates easier cleaning and maintenance
- The polished surface provides a smooth, reflective, and shiny finish which amps up the visual appeal of the pipes
