FORGED FITTINGS – PLUG
Structural Features:
A Forged Plug is a solid, threaded or socket-welded fitting used to seal the end of a pipe or fitting.
It is typically installed in unused or future outlets to stop flow and maintain system pressure integrity.
Forged plugs are compact, durable, and pressure-resistant, making them ideal for high-pressure small bore piping systems.
 
Plug Types:
Square Head Plug
Hex Head Plug
Round Head Plug
Available in Threaded (THD) and Socket Weld (SW) connections
 
Standards:
ASME B16.11
MSS SP-79 / SP-83 / SP-95
BS 3799 (optional)
 
Pressure Ratings:
Class 2000 / 3000 / 6000
Suitable for high-pressure and high-temperature applications
 
Applications:
Forged plugs are used to:
Close off unused pipe openings
Maintain pressure seal
Facilitate future expansion or testing
Commonly found in:
 
Oil & Gas systems
Chemical pipelines
Steam and water systems
Skid-mounted equipment
Instrumentation and valve manifolds
 
 
Common Materials:
Carbon Steel (ASTM A105)
 
Stainless Steel (ASTM A182 F304, F316)
 
Alloy Steel (ASTM A182 F11, F22)
Also available in Duplex, Monel, Inconel, and other special alloys
 
Recommendation:
Forged plugs offer a simple and highly reliable sealing solution for high-pressure piping systems.
They are essential for system maintenance, flexibility, and safety, especially when future system modifications are expected.
Their compact size and high strength make them an economical and effective choice for end closures.
