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.
The United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada, commonly known as the United Association (UA), is a labor union which represents workers in the plumbing and pipefitting industries in the United States and Canada.
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.
Process piping and power piping are typically checked by pipe stress engineers to verify that the routing, nozzle loads, hangers, and supports are properly placed and selected such that allowable pipe stress is not exceeded under different loads such as sustained loads, operating loads, pressure testing loads, etc., as stipulated by the ASME B31, EN 13480, GOST 32388, RD 10-249 or any other ...
