Super Duplex S32750 Steel Pipe Specifications
| Specifications | ASTM A 790 ASME SA 790 |
| Standards | ASTM, ASME, and API |
| Outer Diameter | 1/2″ - 36″ (13.7 mm - 914.4 mm） |
| Wall Thickness | 2 mm - 50 mm |
| Schedule | SCH 5, SCH10, SCH 40, SCH 80, SCH 80S, SCH 160, SCH XXS, SCH XS are different schedules used in pipe sizing. These schedules determine the thickness of the pipes and are important in various industries. SCH 5 refers to a pipe schedule with a thin wall thickness, suitable for low-pressure applications. It is commonly used in industries where cost-effectiveness is a priority. SCH 10 is slightly thicker than SCH 5 and is used for applications with a higher pressure requirement. It is commonly found in residential plumbing, as well as in industries like chemical processing. SCH 40 is a widely used schedule known for its medium wall thickness. It is preferred for applications where a balance between pressure and cost is essential. SCH 40 pipes are popular in HVAC systems, water supply, and drainage systems. SCH 80 has a thicker wall compared to SCH 40 and is used for higher pressure applications. It is commonly used in industries like oil and gas, petrochemicals, and refineries. SCH 80S is similar to SCH 80 but is specific to stainless steel pipes. The "S" denotes stainless steel. Its durable nature makes it suitable for applications that require resistance to corrosion and higher strength. SCH 160 refers to an extra-strong pipe schedule with a significantly thicker wall thickness. It is utilized in extreme pressure applications where the utmost strength is required. Industries such as power plants and chemical processing often employ SCH 160 pipes. SCH XXS stands for double extra strong, indicating a pipe schedule with an exceptionally thick wall. This schedule is used for exceedingly high-pressure systems, such as steam lines in power plants or heavy chemical processing. SCH XS, on the other hand, refers to extra strong pipes with a wall thickness greater than SCH 40 but less than SCH 80. It is frequently used in applications that require a higher strength than SCH 40 but do not require the extra thickness of SCH 80 pipes. Overall, these various pipe schedules offer flexibility in selecting the right thickness and strength based on the specific requirements of different industries and applications. |

Super Duplex S32750 Steel Pipe Features
1. Acid corrosion resistance
The higher chromium and molybdenum content of ASME SA790 UNS S32750 pipe makes it more resistant to the overall corrosion of organic acids such as formic acid and acetic acid. 2507 material is also very resistant to inorganic acids, especially those containing chlorides. 316L cannot be used in hydrochloric acid environment, and local corrosion or overall corrosion may occur, while duplex 2507 pipe can be used in dilute hydrochloric acid environment, and has strong damage resistance and crevice corrosion resistance. Duplex 2507 pipe has greater corrosion resistance to dilute chloride mixed sulfuric acid than 904L, an austenitic alloy designed to resist pure sulfuric acid corrosion.
2. Resistant to stress corrosion cracking
The duplex structure of 2507 makes it highly resistant to stress corrosion cracking, and due to the high alloy content, super duplex F53 pipe has better corrosion resistance and strength than 2205.
3. Resistance to intergranular corrosion
The lower carbon content of super duplex 1.4410 pipe greatly reduces the risk of carbide precipitation in the intergranular during heat treatment, so 2507 alloy has a strong resistance to carbide-related intergranular corrosion.
4. Mechanical properties
2507 stainless steel pipe has high compressive strength, impact strength, low thermal expansion coefficient and high thermal conductivity. Duplex 2507 SCH 10 pipe is composed of a variety of alloy elements, its high strength is one of the biggest advantages of this steel pipe, it has high hardness, can withstand very large pressure, and is also very wear-resistant so that it can prolong the service life.
Application of ASTM A790 UNS S32750 Pipe
Super duplex S32750 steel pipe has higher corrosion resistance and better mechanical properties than duplex stainless steel pipe 2205. Often used in offshore oil platforms (heat exchanger tubes, water treatment and water supply systems, fire protection systems, water spray systems, water stabilization systems), desalination equipment and other special chemical environmental equipment. Applications include: oil and gas industry equipment. Offshore platforms, heat exchangers, underwater equipment, fire fighting equipment. Chemical processing industry, vessel and plumbing industry. Desalination plants, submarine pipelines. Mechanical components (high-strength, corrosion-resistant components), energy industry FGD systems, industrial scrubbing systems, absorption towers, etc.
Processing Technology of Super Duplex S32750 Steel Pipe
Super duplex S32750 stainless steel pipe includes UNS S32750 seamless pipes and UNS S32750 welded pipes, and the processing technology of Duplex 2507 SCH 40 pipe includes hot rolling, cold drawing, cold drawing processing, welding, etc. Among them, hot rolling is to heat the billet to a certain temperature and then extrude it, which is often used to produce large-diameter steel pipes. Cold drawing is to draw the hot-rolled steel pipe after cold treatment to improve the precision and smoothness of the steel pipe. Cold drawing processing is the processing and cutting of steel pipes on the basis of cold drawing to obtain the required length and size. Welding is to join multiple steel pipes through welding technology to form a longer piping system.
