Type A Stainless Steel Stub End
Type A Stub End
ASME B16.9/ ASTM A403
The Type A stainless steel stub end is a high-quality ASME B16.9 stainless steel pipe fitting designed for use with lap joint flanges, providing an efficient and cost-effective way to connect piping systems. The Type A stainless steel stub end features a flat welding surface and a shorter, thinner hub near the pipe, ensuring easy installation and reliable performance. Type A stainless steel stub ends are commonly used in applications where frequent disassembly is required or in corrosive environments where the flange material can differ from the stub end.
Manufactured to meet international standards such as ASME, ASTM, JIS, and DIN, our Type A stainless steel stub ends deliver precision, durability, and corrosion resistance, making them ideal for industries such as chemical processing, petrochemical, and water treatment.
