| High Light | Butt Weld Stub End ，Seamless SS Stub End ，ASME B16.9 Fittings | ||
The Butt Weld Seamless Stainless Steel Stub Ends are manufactured from seamless stainless steel pipe, providing uniform wall thickness and consistent mechanical properties around the entire circumference. Designed to ASME B16.9, these lap joint stub ends create strong, leak-free connections when butt welded to the pipeline and paired with lap joint flanges.
Because the fitting is formed from a single seamless tube, there is no longitudinal weld seam to become a weak point under cyclic loading or high temperature service. This makes our butt weld seamless stub ends particularly suitable for steam piping, thermal power plants and other applications where weld integrity and pressure retention are critical. Every fitting features accurately machined weld bevels that reduce onsite welding time and ensure full penetration welds.

Seamless stainless steel pipe used for production is sourced from accredited steel mills with EN 10204 3.1 certificates. During manufacturing, each butt weld seamless stub end is checked for wall thickness uniformity, bevel geometry and surface defects. Hydrostatic testing and eddy current inspection can be performed to verify the integrity of the seamless body.
Our ISO 9001:2015 certified quality system covers the complete production chain, and our inspectors have extensive experience with international steam piping projects in Europe, the Middle East and Southeast Asia. We are confident in the long term reliability of our seamless fittings.
