Forged Steel Anvilets
Anvil Anvilets provide a strong branch pipe connection,
considerably stronger than a welded pipe-to-pipe connection.
Consequently, with good welding procedures, Anvil Anvilets
offer greater resistance to distortion and bursting.
Anvil Anvilets readily and economically permit the adding of
branch connectors to existing piping installations, eliminating
the relatively higher cost of cutting or disassembly and reassembly required for the installation of tees.
Installation Note
Anvil Anvilets are designed to have no more than a 1⁄16" gap
(1.6mm) between the base or skirt of the Anvilet when it is
seated directly upon the appropriate run pipe. However, it is
recommended that the skirt of Anvilets be held slightly above
the run pipe and tack welded to provide a small continuous
root gap between the skirt and run pipe before completing the
all-around welding beads or fillet.
Anvil Anvilets of the same outlet size as a header or run pipe
size (i.e. “Full Size” Anvilets) are so proportioned that the
(ellipticallyshaped) hole in the header pipe has the minimum
weakening or distortion effect, and yet provides good fluid flow
characteristics.
Specifications
Chemical and physical properties are rigidly controlled to ensure
consistently high quality. Physical and chemical test reports are
available on request. Traceability of individual Anvilets can be
established through the heat code of each fitting.
Anvil Anvilets meet the requirements of MSS standard SP-97.
They are forged from steel which complies with ASTM A105.
Threaded Anvilets - conform with ASME B1.20.1.
Socket-Weld Anvilets - dimensions conform with ASME B16.11.
Buttweld Anvilets - ends conform with ASME B16.25.
Reinforcement Requirements
ASME B31.1 Power Piping Code
ASME B31.3 Refinery Code

Specials
Your local Anvil Branch will be more than happy to assist you with
specially machined outlets and those made of alloy material.
Pressure Temperature Ratings
MSS standard Practice SP-97 gives the following correlation
between fitting pressure class and pipe schedule number/wall
thickness designation for calculation of pressure-temperature
ratings:

Fitting
Anvil Anvilets are clearly marked with the following:
• Outlet size

• Range of run pipe sizes that the Anvilet will fit
• The weight, schedule number, or pressure class
• The material specification
• Steel heat code identification

The maximum allowable pressure of a fitting is computed in
accordance with the applicable piping code or regulation for
straight seamless header (run) pipe or for material of equivalent
composition and mechanical properties to the fitting. Any
corrosion or mechanical allowances and any reduction in
allowable stress due to temperature or other service conditions,
must be applied to the pipe and fitting alike.
