Type B Stainless Steel Stub End
Type B Stub End
ASME B16.9/ ASTM A403
The Type B stainless steel stub end is a durable and precision-engineered ASME B16.9 stainless steel pipe fitting designed for use with standard slip-on flanges. Featuring a longer hub and thicker end compared to the Type A stainless steel stub end, the Type B stainless steel stub end is built to handle more demanding applications, providing enhanced strength and pressure resistance. Ideal for high-pressure piping systems, this stub end ensures reliable performance in industrial environments where durability and stability are critical.
Manufactured to meet international standards such as ASME, JIS, and DIN, our Type B stainless steel stub end are perfect for applications requiring robust, corrosion-resistant fittings, commonly used in industries such as oil and gas, chemical processing, and power generation.
