HiSET (High School Equivalency Test) [1] [2] is an alternative to a U.S. high school diploma and the GED test. The test was designed based on the OCTAE College and Career Readiness Standards for Adult Education. [3] It is governed by ETS and is provided in cooperation with relevant authority in 26 states and 5 territories in the United States. [4]
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.
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.

A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect
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.
Pipelayers hanging a pipe on the wall of the Church Avenue station of the New York City Subway. A pipelayer (or pipe-layer or drain layer) is a skilled tradesman who lays pipe, such as for storm sewers, sanitary sewers, drains, and water mains. [1] Pipelayers may grade (i.e., level) trenches and culverts, position pipe, or seal joints. [1]
