Pipe Fittings

Unlike a straight length of pipe or a flange bolted connection point, a pipe fitting is genuinely defined by introducing a change of direction, a change of size, or a branch into an otherwise straight pipe run. Elbows change direction, tees and crosses create branches or junctions, reducers change size, caps terminate a run entirely. Every fitting’s single organizing purpose is to alter the pipe run’s geometry at that exact point — something a straight length of pipe cannot do on its own, by definition.

Connection method is a genuinely independent second axis of variation, distinct from which geometric fitting you choose. Fittings connect to the adjoining pipe by buttweld — beveled ends welded directly together, for high-pressure or critical service requiring precise alignment and full weld penetration — by socketweld — the pipe end inserts into a recessed socket and is fillet-welded, faster and easier to align for smaller-bore high-pressure lines — or by threaded connection — NPT or BSP threads for low-pressure, easily disassembled joints without any welding equipment at all. These connection methods exist independently of whichever geometric fitting type — elbow, tee, reducer — you actually need.

A genuine, honest limitation is worth flagging specifically for socketweld fittings. A socketweld joint is required to leave a small gap between the inserted pipe end and the base of the socket, specifically to allow for weld shrinkage during cooling — without it, the weld can crack. This deliberately required gap creates a stagnant pocket where process fluid can collect and is very difficult to fully drain or clean, a genuine crevice-corrosion and hygiene concern that a buttweld fitting, with no internal gap since the pipe ends butt directly together, doesn’t have.
