Graphite Electrode Nipple
Precision-machined 3TPI and 4TPI connections for stable current transfer.
Request this productOverview
Engineered for dependable operation.
Graphite electrode nipples are matched to the electrode grade and thread system. Machining and inspection focus on thread profile, socket fit, dimensional accuracy, bulk density, strength and electrical performance.\n\nStandard and long nipple options can be discussed for different electrode diameters.

01
Electrical load
Grade and resistivity should match transformer power and current density.
02
Mechanical stability
Strength, density and handling practice affect breakage risk and consumption.
03
Joint compatibility
Thread system, nipple designation, socket accuracy and tightening practice work together.
