Self-Aligning Flange Sets
Engineers faced with building piping systems know a coupling must meet one or more of the following requirements:
- Is easy to install, remove and reuse
- Guarantees contact of the two pipe ends
- Prevents pipe sections from moving apart
- Keeps the pipe sections aligned
- Guarantees electrical conductivity
- Is airtight
Commercial couplings are available in several types and each of which fulfills specific requirements. The Self-Aligning Flange sets will meet all of the above requirements. The SAF connector design is easy to install. It features a captured O-ring seal that is out of the product contact area and is air tight. The flange or clamp provides positive clamping action to resist flexural and torsional loads. It conforms to the support and hanging requirements. As the stub end flanges are drawn together by the clamp assembly, the O-ring seals without full compression when the stub end makes metal to metal contact.
Standard Features
The Young Industries patented Self-Aligning Flange sets are offered in a large selection of standard sizes. It is available in 2″, 3″ 4″, 5″, 6″, 8″, 10″ and 12″ diameters in both tubing and pipe sizes. The sets are offered in carbon steel, aluminum, and stainless steel. All the V-Retaining couplings are constructed with formed sections with the band made of 304 stainless steel where product contacts, with the bolt constructed of 431 stainless steel and with 347 stainless steel self-locking nut.
The standard Self-Aligning Flange sets of
- Style LP – 15 PSIG working pressure low pressure with over center latch V-retainer.
- Style MP – 50 PSIG working pressure medium pressures with T-handle V-retainer.’
- Style HP – 150 PSIG working pressure with high pressure lap flanges, full penetration welds.
The Self-Aligning Flange sets can be furnished in several design variations. We offer technical services to assist you on special applications. Contact us for current pricing and delivery or in you have any questions.
The standard SAF uses an over-center latch style V-Retainer coupling to join the flange sets. The V-Retainer coupling exerts a uniform compressive force against the stub flanges. The over-center latch style reduces time when you need to removal sections of the piping system for clean-out or maintenance. The over-center handle does not require tools to open or close the coupling once you make initial adjustment. A nut provides adjustable tension. The self-energizing latch and retainer reduces accidental opening of the coupling. Note: any internal pressure must be released before opening the coupling. Although the SAF couplings form a permanent pipe connection, it is easily disassembled. Since each joint is a union, it is simple for a pipe to be removed, an elbow to be replaced by a tee to extend a system, or a valve, strainer or other component to be installed later. Fittings can be assembled loosely and rotated to line up with mating components before tightening. This simplifies working in tight spaces around existing piping structures, or equipment.
