Pipe Stub Ends
VEFLOX precision-manufactures premium pipe stub ends designed exclusively for use with Lap Joint Flanges. Engineered to reduce overall material costs and dramatically simplify pipeline installation, our stub ends allow the backing flange to rotate freely, ensuring rapid and flawless bolt-hole alignment in systems requiring frequent dismantling and inspection.
Detailed Technical Specifications
Long Pattern: Conforms to ASME B16.9 (Allows for greater clearance during welding).
Type B: Designed for use with Slip-On Flanges (acts as a backing flange).
Type C: Fabricated from standard pipe with a flared end.
Alloy & Exotic: Duplex UNS S31803, Super Duplex, Inconel, Monel
Carbon Steel: ASTM A234 WPB
Schedules: Sch 5s, Sch 10s, Sch 40s (STD), Sch 80s (XS), Sch 160.
Core Advantages
Significant Cost Efficiency
Because only the stub end comes into contact with the fluid, you can utilize a high-grade exotic alloy for the wetted stub end while using a highly economical carbon steel backing flange.
Rapid Bolt Alignment
The accompanying lap joint flange rotates freely over the pipe, eliminating the need to perfectly align bolt holes during the welding process, drastically cutting installation time.
Maintenance Accessibility
Highly recommended for piping systems requiring frequent dismantling for inspection and cleaning, allowing for rapid unbolting without disturbing the welded joint.
