S32750 Alloy Steel Reducing Flange CL 150 3" SW High Performance
Product Description
These high-performance reducing flanges are manufactured from premium S32750 alloy steel (super duplex stainless steel), strictly complying with industrial standards and designed for Class 150 (CL 150) pressure rating. With a nominal size of 3 inches and Socket Weld (SW) connection type, they feature a reducing structure to realize smooth diameter transition between different pipeline sizes. The flanges offer excellent corrosion resistance, high strength, stable mechanical properties and reliable sealing performance, widely used in high-demand industrial piping systems requiring durability and leak-proof connections.
Key Parameters
- Material: S32750 Alloy Steel (Super Duplex Stainless Steel)
- Type: Reducing Flange
- Pressure Class: CL 150 (Class 150)
- Size: 3 Inch (Nominal Size)
- Connection Type: Socket Weld (SW)
- Process: Forged
- Features: High performance, reducing structure, corrosion resistant, high strength, socket weld, forged
- Application: Oil & gas, petrochemical, marine, offshore, chemical, industrial high-pressure piping
Application
Widely applied in oil and gas transmission pipelines, petrochemical plants, offshore platforms, marine engineering, chemical processing equipment and high-pressure industrial piping systems. The reducing structure is specially designed for smooth transition between 3-inch main pipelines and smaller diameter branch pipes, reducing flow resistance and ensuring stable medium transmission. Suitable for harsh working environments with corrosive media, high pressure and temperature fluctuations.
Product Advantages
- Premium S32750 alloy steel (super duplex) provides excellent corrosion resistance, pitting resistance and high mechanical strength, adapting to harsh industrial environments.
- CL 150 pressure rating ensures stable performance under medium-high pressure working conditions, meeting industrial piping requirements.
- 3-inch nominal size with socket weld (SW) connection, easy to install, firm and reliable, reducing leakage risks.
- Reducing structure realizes smooth diameter transition, minimizing flow resistance and ensuring efficient medium transmission.
- Precision forging process enhances material density, improves structural stability and extends service life.
- High performance design, compatible with various industrial piping systems, strong versatility and interchangeability.
Installation & Use
Before installation, check the flange surface, socket weld port and sealing face for scratches, damage or contamination; clean the connection parts thoroughly. Insert the pipe into the socket weld port, ensure proper fit, and use professional welding process to fix the connection. Tighten bolts evenly and symmetrically to ensure reliable sealing. Conduct a pressure test after installation to confirm no leakage before formal operation.
Precautions
Store in a dry, clean and ventilated warehouse to avoid moisture, corrosion and surface scratches; handle with care during transportation to prevent collision and deformation. Use within the rated pressure (CL 150) and temperature range; avoid overloading or improper installation. Professional welding and installation personnel are recommended to ensure welding quality and connection reliability.
Delivery
Ship within 7–15 working days after order confirmation; shipped by sea, air or express according to customer requirements. A logistics tracking number will be provided promptly to facilitate order tracking.
Payment Terms
T/T, L/C, Western Union, PayPal; 30% deposit upon order confirmation, balance paid before shipment.
Packing
Anti-rust film wrapping + foam protection + plastic caps + plywood wooden case; shockproof, moisture-proof and anti-scratch, suitable for long-distance ocean transportation and international shipping, ensuring the flange is intact on delivery.
