NICKLE ALLOY STEEL FORGED FITTING ASME SB564 N10276 BOSS B16.11 MSS SP-97
A boss fitting, also referred to as a forged branch outlet or half coupling, is a type of forged branch fitting governed by ASME B16.11. It is a compact heavy-wall fitting welded onto the outer wall of main pipes to tap small branch lines, instrument connections, drain and vent ports. It is simply called "boss head" in domestic engineering field.
| Item | Boss (Half Coupling / Boss Head) | Olet (Weldolet / Sockolet) |
| Structure | Simple curved base with limited reinforcement | Fully forged with smooth transition for optimal stress distribution |
| Pressure Resistance | Medium and sub-high pressure service | High-temperature & high-pressure heavy-wall main pipelines |
| Cost | Low cost, compact size | Higher cost, bulkier structure |
| Application | Instruments, drains and small branches | Large-bore branches on main process pipelines |
Boss coupling used in the hose industry is a quick-disconnect fitting for steam and air hoses, which is completely different from forged pipe boss heads. The term "boss" in piping engineering exclusively stands for forged saddle branch boss fittings.
A boss is a saddle-type forged half coupling branch outlet welded to the outer wall of main pipes, specially manufactured as reinforced connections for instruments, vents and small-bore branches.
