Pipe fitter training pdf

Pipefitters usually begin as helpers or apprentices. Other types of piping systems include steam, ventilation, pipe fitter training pdf, chemicals, fuel, and oil. Pipefitter apprenticeships are controlled and regulated provincially, and in some cases allow for advance standing in similar trades upon completion.

In the United States, many states require pipefitters to be licensed. Requirements differ from state to state, but most include a four- to five-year apprenticeship. Pipefitters install, assemble, fabricate, maintain, repair and troubleshoot pipe carrying fuel, chemicals, water, steam and air in heating, cooling, lubricating and various other process piping systems. Pipefitters are employed in the maintenance departments of power stations, refineries, offshore installations, factories and similar establishments, by pipefitting contractors. Wages vary from area to area, based on demands for experienced personnel and existing contracts between local unions and contractors. Pipe layers operate the backhoes and trenching machinery that dig the trenches to accommodate the placement of sanitary sewer pipes and stormwater sewer drainpipes.

They use surveyor’s equipment to ensure the trenches have the proper slope and install the pieces of pipe in the trenches, joining the ends with cement, glue or welding equipment. Using an always-open or always-closed valve called a tap, pipe layers connect them to a wider system and bury the pipes. 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. They install manual, pneumatic, hydraulic and electric valves in pipes to control the flow through the pipes or tubes. These workers create the system of tubes in boilers and make holes in walls and bulkheads to accommodate the passage of the pipes they install. This page was last edited on 25 October 2017, at 18:42.

What is needed to come up with a production rate? A duration of time, the manhours involved, and an amount of work produced? This section is here to document this. What information do you have that you can share? It seems that the most of the rates here are equipment rates. Productivity rates for “Civil Infra. Gas Projcts” of Middle East Countries.

Any one can help ? I am struggling to see any logic behind the productions per hour on the drainage? 33m per hour for 150mm drainage in runs exceeding 30m or greater is impossible – unless installed via trenchless methods! I calculate my drainage productions to include dig, bed and surround, pipe laying and backfilling compacting in accordance with the specification and would never price on more than 30 – 35m per DAY for a 150mm UPVC pipe at a depth not exceeding 1m.
