Butt Weld Seamless Stainless Steel Stub Ends
Product Overview

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.

Quality Assurance

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.

Frequently Asked Questions
What is the advantage of seamless stub ends over welded ones?
Seamless stainless steel stub ends have no longitudinal weld seam, which removes the risk of weld defects and provides uniform strength around the full circumference. They are preferred for high pressure steam and cyclic loading applications.
What welding method should be used for installation?
Butt weld stub ends are typically installed using TIG welding for small diameters and smaller wall thickness, or SMAW for larger sizes. The machined 30 degree bevel allows full penetration welding with the matching pipe.
Can you provide seamless stub ends above 24 inches?
Seamless stainless steel pipe is commonly available up to 24 inches. For larger diameters, we offer welded construction with full radiographic testing to equivalent quality levels.
Do you supply the matching lap joint flanges?
Yes. We can supply matching lap joint flanges in the same material grade and standard, ensuring perfect dimensional compatibility and simplifying your procurement.
