Table of Contents

Module ID 00106 - Advanced Blueprint Reading

Pipefitters need to understand how to read piping

and instrumentation drawings (P&IDs), which

are also known as blueprints or site plans. These

schematic diagrams show process flows, functions,

equipment, pipelines, valves, instruments,

and controls needed to operate the system. The

blueprint package included in the Appendix of

this module contains plans that demonstrate how

P&ID information appears on the plans and what

the information means. (7.5 hours)



Module ID 38102 - Advanced Pipe Fabrication

Pipe fabrication involves the use of either ordinate

tables or trigonometry to create fittings and pipe

assemblies that suit a process application. Producing

ordinates and using them to lay out miters and

laterals is important, as are alternative methods

for laying out the cuts for laterals, saddles, and

mitered turns. In this module, formulas are provided

for putting together multiple offsets around

obstacles of both equal and unequal spread. (15 hours)



Module ID 08303 - Stress Relieving and Aligning

Stress relieving is the process of preheating and

post weld heat treatment to keep welds from

distorting a pipe assembly. Alignment is the

reason for stress relieving, because if the pipe

will not fit up accurately to machinery, dynamically

balanced pumps will be unbalanced by the

distortions of the piping attachments. A skilled

pipefitter takes charge of these situations, working

with millwrights and others to prevent misalignments

and problems which stem from them. (10 hours)



Module ID 08304 - In-Line Specialties

Special fittings and instruments used in process

piping equipment are known as in-line specialties

and described in system documentation as “specials.”

This category includes steam traps, desuperheaters,

bursting discs, strainers, and related

equipment. Steam traps protect the lines against

water hammer while desuperheaters reduce the

temperature of steam. Strainers are used with

many types of fluids to keep solids from clogging

pipes. Bursting discs provide emergency pressure

relief to prevent very high-pressure surges from

damaging equipment. Each in-line specialty item

serves a specific purpose and must be installed,

monitored, and removed by knowledgeable pipefitters

who may be working in tandem with other

professionals for coordinated activities across the

pipe run. (25 hours)



Module ID 08305 - Special Piping

Pipefitters must be prepared to assemble small

piping and tubing. While these jobs are infrequent,

they still require a clear understanding of

the skills needed to correctly and safely connect

and route pipe on a smaller scale. Some of these

skills include brazing, soldering, pipe bending,

and installing various fittings made of copper,

stainless steel, aluminum, and brass. (10 hours)


Module ID 08306 - Hot Taps

When it is necessary to connect to pipes that cannot

be shut down or emptied, fluid pressure must

be contained to prevent leaks. The method for

doing this is referred to as hot tapping, and its

pro-cedures will vary according to what is being

conveyed through the line. In some situations, it

may be possible to temporarily stop the flow while

connections are made; this is where line stop plugs,

pipe freezing, and pipe plugging become important.

Hot tapping is not a regular part of a pipefit-

ter’s career, but it is important to understand

the environmental factors associated with it as

well as ways to safely assist any contractors called

on to perform it. (25 hours)



Module ID 08307 - Maintaining Valves

Understanding the function and assembly of

valves is essential to the pipefitter’s career. While

most valves are replaced rather than maintained,

it is important to understand the procedures for

both. Knowledge on valve maintenance contributes

to troubleshooting issues within a pipe run,

with the function of valves as a pivotal point.

(15 hours)



Module ID 08308 - Fundamentals of Crew Leadership

When a crew is assembled to complete a job, one

person is appointed the leader. This person is usually

an experienced craft professional who has

demonstrated leadership qualities. While having

natural leadership qualities helps in becoming an

effective leader, it is more true that “leaders are

made, not born.” Whether you are a crew leader

or want to become one, this module will help

you learn more about the requirements and skills

needed to succeed (25 hours)
