Pipefitter (or steamfitter), a person who lays out, assembles, fabricates, maintains, and repairs large-sized piping systems capable of enabling high-pressure flow. [9] Plasterer, a tradesperson who works with plaster, such as forming a layer of plaster on an interior wall or plaster decorative moldings on ceilings or walls. [10]

Polypropylene fittings for solvent welding. A solvent is applied to PVC, CPVC, ABS or other plastic piping to partially dissolve and fuse the adjacent surfaces of piping and fitting. Solvent welding is usually used with a sleeve-type joint to connect pipe and fittings made of the same (or compatible) material.
Pipelayers should not be confused with pipefitters. Both trades involve pipe and valves and both use some of the same tools. [2] However, pipelayers usually work outside, laying pipe underground or on the seabed, while pipefitters typically work inside, installing piping in buildings or ships. [2] One author summarizes the different tasks this way:

Plumbing plunger in a sink. A plunger is a device driven by or against fluid pressure. [1] In plumbing, the term plunger commonly refers to handheld tools used to clear blockages in drains and pipes.
In addition to welders and welding machine operators, there are also schemes to independently certify welding inspectors and related specialities. The duties of the welding inspector are described in ISO 14731; [12] however the requirement for inspector certification are not standardized, so there are differences in requirement between the various schemes.
