A structural pipe fitting, also known as a slip on pipe fitting, clamp or pipe clamp is used to build structures such as handrails, guardrails, and other types of pipe or tubular structure. They can also be used to build furniture and theatrical riggings. The fittings slip on the pipe and are usually locked down with a set screw.
Using an always-open or always-closed valve called a tap, pipe layers connect them to a wider system and bury the pipes. whereas, Pipe fitters plan and test piping and tubing layouts; cut, bend or fabricate pipe or tubing segments; and join those segments by threading them, using lead joints, welding, brazing, cementing, or soldering them together.
Pipe fitters had to learn more about instrumentation and control theory, and a new trade was born. [ 2 ] Today, instrument mechanics combine the skills of repair and calibration with the theoretical understand of how the instrumentation and control works, which is a specialised combination of electronic and mechanical disciplines.
Test specimens for ASTM D790 flexural testing must meet the dimensional tolerances of ASTM D790. The North American CIPP industry has standardized around the standard ASTM F1216 which uses test specimens oriented parallel with the pipe axis, while Europe uses the standard EN ISO 11296–4 with test specimens oriented in the hoop direction.
Related but distinct crafts include machinists, mechanics and mechanical fitters. As the name suggests, the original function of a millwright was the construction of flour mills , sawmills , paper mills and fulling mills powered by water or wind , made mostly of wood with a limited number of metal parts.
