Information
Threaded Flange 1 1/2'' 304L NPT Class 150 ASME B16.5 is designed for threaded pipe connections without welding. It is commonly used in industrial installations where welding is impractical or not permitted, while providing a reliable and pressure-tight connection through the tapered NPT thread.
304 / 304L Stainless Steel
304 / 304L stainless steel is the most widely used corrosion-resistant stainless steel grade. It offers excellent weldability, formability, and resistance to many chemicals, making it suitable for industrial and hygienic applications.
Equivalent grades: 1.4301, 1.4306, 1.4307, AISI 304L, SS304, X5CrNi18-10.
Advantages of 304 / 304L Stainless Steel
- Excellent corrosion resistance
- Outstanding weldability
- Non-magnetic
- Excellent ductility
- Good impact strength
- Wide operating temperature range
Applications
- Chemical industry
- Food processing industry
- Equipment manufacturing
- Pressure vessels
- Industrial piping systems
- General engineering
