Anvil

Anvil International is a manufacturer of pipe hangers, pipe supports, seismic bracing, and grooved fittings for commercial and industrial piping systems, with a product heritage dating to 1850. The Anvil International name has been in use since 2000, with headquarters in Exeter, New Hampshire. Anvil is one of the largest and most complete manufacturers of pipe fittings, pipe hangers, and piping support systems in the world, manufacturing at three primary U.S. facilities in North Kingstown, Rhode Island; Henderson, Tennessee; and Columbia, Pennsylvania. Anvil's ISO-certified facilities use recycled materials in manufacturing, and the company is a member of the U.S. Green Building Council.

Product Lines

Pipe Hangers and Supports

Anvil International pipe hangers and supports cover the full range of standard support configurations for residential, commercial, and industrial piping. The line includes clevis hangers, riser clamps, beam clamps, spring hangers, roller supports, and trapeze assemblies for copper, steel, cast iron, and plastic piping from small-bore residential through large-diameter industrial applications.

Seismic Bracing

Anvil International seismic bracing products restrain piping against lateral and longitudinal movement from seismic events, meeting IBC seismic design categories and OSHPD requirements for healthcare facilities. The line includes sway brace assemblies, clamp attachments, and support components for commercial and institutional mechanical systems in seismic zones.

Grooved Fittings

Anvil International grooved fittings provide mechanical pipe joining for fire protection, HVAC, and plumbing piping. The line includes couplings, elbows, tees, reducers, and specialty fittings for grooved-end pipe. Grooved joining eliminates welding or threading at the fitting location and allows the piping to flex for thermal expansion and vibration accommodation.

Pipe Accessories and Hardware

Anvil International pipe accessories include malleable iron and carbon steel components for completing piping support installations: beam attachments, anchor bolts, rods, and miscellaneous hardware used with the hanger and support product line.

Why Contractors Specify Anvil International

Mechanical and plumbing contractors specify Anvil International because the catalog covers the full range of standard support configurations from small-bore copper through large-diameter industrial pipe and seismic bracing. Anvil manufacturing is ISO certified, with primary production in Rhode Island, Tennessee, and Pennsylvania. Anvil is a U.S. Green Building Council member and uses recycled materials in manufacturing. The brand's heritage from the Grinnell product line, in use since 1850, means Anvil hanger catalog numbers and design tables are familiar references for engineers and contractors across U.S. commercial construction.

How to Choose an Anvil International Product

The most important decision variable is the pipe material, pipe size, and support configuration required by the project specification. Anvil hangers are selected from standard catalog tables matching pipe size and hanger type to allowable load and span. Clevis hangers support horizontal pipe from a rod above. Riser clamps support vertical pipe at each floor. For seismic zones, sway brace assemblies must be added to meet code requirements. Grooved fittings are selected by pipe outside diameter and groove specification. For engineer-specified installations, the Anvil catalog provides load tables and selection guidance.

FAQs

Where are Anvil International products manufactured?
Anvil International manufactures at three primary U.S. facilities: North Kingstown, Rhode Island; Henderson, Tennessee; and Columbia, Pennsylvania. ISO-certified facilities use recycled materials. Headquarters are in Exeter, New Hampshire.

What warranty does Anvil International offer?
Warranty terms are available through authorized distributors.

What is the difference between Anvil clevis hangers and riser clamps?
Clevis hangers support horizontal piping, suspending the pipe from a rod attached to the structure above. Riser clamps support vertical piping at each floor level, transferring pipe weight to the floor structure. Both are selected based on pipe size and load requirement.

What pipe sizes do Anvil International pipe hangers cover?
Anvil pipe hangers cover copper, steel, cast iron, and plastic piping from small-bore residential through large-diameter industrial and commercial sizes. The full size range by hanger configuration is published in the Anvil product catalog.

Are Anvil seismic bracing products compliant for healthcare facilities?
Anvil seismic bracing is designed to meet IBC seismic design categories and OSHPD requirements for healthcare piping. Verify the selected Anvil seismic assembly matches the project's seismic design category and code requirements before installation.

How do Anvil grooved fittings compare to threaded or welded fittings?
Anvil grooved fittings provide mechanical joining without welding or threading, which can reduce installation time. Grooved couplings also allow piping to flex for thermal expansion and vibration accommodation, which welded and threaded connections do not provide. Most applicable on systems where rapid assembly, future disassembly, or vibration isolation are priorities.
