Butt weld, forged, &Cast: Vavle &Fitting Insights
Definition:
These have ends designed to be welded directly to pipe ends, creating a strong, leak-proof joint.
Key Features:
Ideal for high-pressure and high-temperature applications.
Offers smooth flow with minimal turbulence.
Requires precise pipe alignment and skilled welding.
Common Materials:
Carbon steel, stainless steel, alloy steel.
Applications:
Oil & gas
Power plants
Refineries
Chemical processing
???? 2. Forged Valves & Fittings
Definition:
Made by shaping metal under high pressure, typically from solid billets.
Key Features:
High mechanical strength due to grain refinement.
Smaller sizes (usually < 2” or 3”).
Available as socket weld or threaded connections.
Grades:
A105 (carbon steel), F304/F316 (stainless steel), F11, F22 (alloy).
Applications:
High-pressure steam systems
Hydraulic systems
Compact piping arrangements
????️ 3. Cast Valves & Fittings
Definition:
Produced by pouring molten metal into molds and allowing it to solidify.
Key Features:
Can produce complex shapes and larger sizes more economically.
Slightly lower mechanical strength than forging.
Usually has flanged ends or butt welds.
Common Standards:
WCB (carbon steel), CF8/CF8M (stainless steel)
Applications:
Water and wastewater
HVAC systems
General industrial use
