This 2-piece design simplifies alignment in large or offset piping runs while retaining full ASME B16.5 compatibility. Available in sizes from ½ inch to 48 inch, it meets pressure class ratings up to 1500 and supports full-face gaskets.
The stub end-to-flange interface maintains bolt load without transmitting pipe stress to the flange body. This avoids fatigue cracking in vibration-prone systems. Using forged stub ends with 1.25× wall thickness ensures weld strength continuity across high-pressure joints.
Each stub end meets ASME B16.9 tolerances, while backing flanges match bolt circles per B16.5 Table 4. Surface finish control at both gasket and weld prep zones supports leak-free sealing and X-ray quality welds.

The stainless stub end prevents corrosion at critical weld zones, reducing turnaround downtime in acid-handling systems.
Thermal expansion tolerance in the stub-flange interface helps avoid stress failures in superheated water lines.
Stub ends resist seawater attack, while coated backing flanges avoid unnecessary material costs in non-wetted areas.
Clean weld prep surfaces (32–63 μin Ra) meet hygienic welding standards in high-purity processing.
The rotating flange simplifies field adjustments during on-site bolt alignment under tight space constraints.
Stub ends in duplex material withstand high chlorides in bleach plant applications, with flanges coated for external humidity.
Sourcing teams gain flexibility by decoupling weld metallurgy from bolting material. Our sets come matched and inspected as per EN 10204 3.1 certification, ready for welding and assembly.
We maintain large-size inventory up to 48 inches with stub end lengths per ASME B16.9, which reduces fabrication time. Optional coatings like hot-dip galvanizing or Xylan offer external protection in buried or corrosive environments.
Check all our Frequently Asked Question
Yes, this is a standard configuration. The stub end handles corrosion while the flanges provides mechanical strength at a lower cost. This pairing meets ASME and NACE guidelines when material compatibility is verified.
Yes, each stub end uses 1.25 times the pipe wall thickness. This ensures full strength through the weld zone under pressure and thermal load. All dimensions comply with MSS SP-43 standards.
Yes, the lap joint flange remains loose over the stub end until bolting. This allows 360° adjustment to align bolt holes during installation. It saves time especially in tight or misaligned pipe runs.
No coating is applied to the stub end to maintain weld quality. However, you can request external coatings like Xylan or HDG for the flange. This protects against corrosion without affecting weld integrity.
Yes, we supply fully matched flange-stub sets with size and class pairing verified before dispatch. This avoids mismatch issues during assembly. You also get single-source for easier documentation.
