Stockist of super duplex stainless steel seamless pipes & tubes in India

Industrial applications exposed to corrosive conditions demand piping that resists pitting and erosion. An ASTM A790 UNS S32750 Pipe refers to a super duplex stainless steel comprising chromium (25%), nickel (7%), and molybdenum (4%). The strength of this material draws from its complex microstructure that has ferritic and austenitic properties.

Mipra Steel was founded in 2011 and has gained over ten years of experience supplying these pipes to various industries. They can be welded or seamless. While the latter is more precise, they are also lower in strength. Welded pipes get preferred in applications that require greater robustness. One of the largest clients of these pipes is the chemical processing sector. These industries require materials that withstand highly abrasive agents and avoid pitting, erosion, and cracking.

Check MTC and origin of raw material before buying SDSS pipe

High strength and corrosion resistance are desirable in pipes for chemical processing and marine applications. Super Duplex Stainless Steel Seamless Pipes & Tubes get favoured for their superb resistance to inorganic acids and chloride environments. These pipes and tubes get manufactured from stainless steel alloys mixed with chromium, nickel and molybdenum. These pipes do not have a seam, as implied by the name. Instead, they get manufactured from a heated billet moulded into a hollow tube.

A hallmark of these components is a strict tolerance to stress cracking, pitting, and crevice corrosion. This property helps them adapt to the needs of oil and gas industries, desalination plants, paper mills, and offshore oil production.

An SDSS Pipe is expensive and relies heavily on high-quality raw materials. Selecting the appropriate dimensions and desired metallurgical properties is crucial to ensure system performance. An MTC or Mill Test Certificate can help customers ascertain that the product features comply with the required norms and technical specifications. The MTC for SDSS pipes conforms to EN 10204 standards relating to steel products. It covers all minute details like dimensional measurements, material grade, results of hydrostatic tests, etc.

Mipra Steel also issues a Raw Materials Certificate to confirm the origin of the materials used to manufacture the SDSS Pipe. It is a sure-shot way to check that the product is fully traceable and comes from materials supplied by reliable vendors. Superior materials with the required metallurgical profile are imperative for the super duplex grade.

Full size range in schedule 10 and sch 40 super duplex steel pipes & tubes

Industries like petrochemicals, seawater equipment, and chemical processing require piping that exhibits brilliant corrosion resistance. An ASME SA790 S32750 Welded and seamless Pipe gets produced from a sturdy material composed of chromium (25%), molybdenum (4%), and nickel (7%). This unique microstructure allows it to offer dependable tolerance for cracking, pitting, and erosion. It works even in environments rife with chloride ions. The mechanical strength of these pipes is very high and delivers a long service life. Both welded and seamless piping gets covered under this specification.

A Super Duplex Pipe is expensive due to its superior mechanical and chemical properties. However, opting for this material pays rich dividends in the long run by reducing wear and tear caused by corrosion. The price ranges from Rs. 500 to Rs 800 per kilogram for standard dimensions and thickness.

Pipe schedules refer to the thickness and pressure rating of a pipe. Schedule 10 and SCH 40 Super Duplex Steel Pipes & Tubes are popular in many industries for process piping. A higher schedule number implies a thicker component that can withstand more pressure. Many manufacturers produce these pipes per the ASME B16 standard. For example, an SCH 40 Pipe of 1/8” has an outside diameter of 0.405” and a wall thickness of 0.068”. In contrast, a Schedule 10 Pipe of 1/8” has an outer diameter of 0.41” and a wall thickness of 0.049”.

Notably, the SCH number relates to, but is different from, the nominal bore. While the outside diameter remains constant, the wall thickness and the inside diameter change with the schedule. Mipra Steel supplies Super Duplex Steel Pipes & Tubes in different parameters based on client needs. While Schedule 10 components have thinner walls, SCH 40 pipes are better suited to more heavy-duty applications.
