Swage Nipples

Swage Nipples

Swage Nipples — ASME B16.11 / related MSS

Savoy Piping Inc. manufactures and supplies swage nipples in socket weld and threaded ends for small-bore process and utility piping. Dimensions and pressure classes follow ASME B16.11 (and MSS SP-79 / SP-83 / SP-95 where applicable), with ASTM/ASME forging grades for chemistry and mechanicals.

Related: Forged fittings hub · 90° Elbow · 45° Elbow · Tee · Cross.

What are Swage Nipples?

Swage nipples (MSS SP-95) are concentric or eccentric reducers with plain, beveled or threaded ends. They change pipe size on small- and mid-bore lines where a forged reducing fitting is preferred over a buttweld reducer.

Selection guidance

Specify concentric or eccentric, end combination (PBE / BBE / TBE / PSE etc.), large×small NPS, schedule and material. Related forms: 90° Elbow · 45° Elbow · Tee · Cross · all forged fittings.

What to put on the PO

Include material grade / ASTM class, end type (socket weld or threaded), fitting form, size, pressure class, quantity, destination, and documentation (EN 10204 3.1 / 3.2, PMI, NACE, TPI). Email sales@savoypipinginc.com.

Frequently asked questions

What are Swage Nipples?

Swage Nipples are forged small-bore fittings used to join pipe, valves and instrumentation with socket weld or threaded ends. Size, class and material must match the piping class.

Which standards apply?

Dimensional: ASME B16.11 for most forged fittings; MSS SP-79 (reducer inserts), MSS SP-83 (unions) and MSS SP-95 (swage nipples / bull plugs) where applicable. Material follows the ASTM forging spec that matches the pipe (A182, A105, A350, A694, B564, etc.).

When should I choose Swage Nipples?

Choose Swage Nipples when the piping class and installation method call for this connection form. Confirm end type, NPS and Class 3000 / 6000 / 9000 on the purchase order.

What should be on the purchase order?

Material grade / ASTM class, end type (SW or threaded), fitting form, size, pressure class, quantity, destination, and documentation (EN 10204 3.1 or 3.2, PMI, NACE, TPI if required). Email sales@savoypipinginc.com.

Concentric vs eccentric swage — which one?

Concentric keeps the centerline; eccentric keeps one side flat — often used on pump suction lines to avoid air pockets. Confirm the pattern on the PO.

ANSI/ASME B16.11 Threaded Swage Nipple Inspection

As specified in the Purchase Requisition and in compliance with the applicable product standard (ASME/ANSI B16.11, MSS-SP-79), all Threaded Swage Nipple are examined and tested. When specified by the standard, pressure testing or hydro-testing of stainless steel threaded swage nipples must be done using water that has less than 30 ppm of chlorides. According to each ASTM Standard, every weld in welded threaded pipe fittings must be radiographed 100 percent of the time. Ultrasonic inspection cannot replace radiography. The contractor or their authorised third party inspector may evaluate and/or observe tests and/or examinations at our facilities. It is our responsibility to let the contractor know that the goods are ready for inspection and testing.

Threaded Swage Nipple Packing & Forwarding

Threaded Swage Nipple are packaged in a way that makes them easy to handle and guards against damage when they are ready for export. We request the buyer's consent before submitting our regular packing technique. Heavy grade plastic protection plugs or caps are included with the open ends of Threaded Swage Nipples. We make sure that caps can fully protect the bevel on bevelled ends. All materials up to 6" in size must be delivered in hardwood boxes or cartons, appropriately secured, and as necessary. Over 6" threaded swage nipple pipe fittings must be delivered on pallets made of wood and secured with metal straps. Pallets must also be shrink-wrapped. For a smooth transfer from the mill to the customer, all shipping documentation is offered.
