Module nine (03105-13) provides the basic knowledge and skills needed to thread and install carbon steel pip- ing systems. In addition, the concepts of assembling and installing grooved piping systems are also presented. The module provides coverage of basic piping system installation considerations and coverage of piping sys- tem hangers and supports.
Teaching Time: 10 hours (Four 2.5-Hour Sessions)
Session time may be adjusted to accommodate your class size, schedule, and teaching style. Prerequisites
Completion of NCCER Core Curriculum. Before You Begin
As you prepare for each session, allow sufficient time to review the course objectives, content, visual aids (including the PowerPoint® presentation), and these lesson plans, and to gather the required equipment and materials. Consider time required for demonstrations, laboratories, field trips, and testing.
Using your access code, download the written examinations and performance profile sheets from www.
nccerirc.com. The passing score for submission into NCCER’s Registry is 70% or above for the written exami-
nation; performance testing is graded pass or fail.

Safety Considerations
This module requires that trainees work with steel piping materials, common hand tools, and powerful rotating machinery and power tools. Personal safety must be emphasized at all times. Trainees should be carefully observed to ensure that they wear the proper PPE, follow safe practices, and give due respect to the hazards of operating power tools and handling metal parts. Any deficiencies must be corrected to ensure future trainee safety as they begin working with even more hazardous systems later in their train- ing and career. All practice sessions and Performance Tasks must be completed under your direct supervi- sion.
Additional Resources
This module presents thorough resources for task training. The following resource material is suggested for further study.

Instructors should view any videos that may be identified in the lesson plan before using them to ensure their suitability. The videos can provide teachable moments in both proper and improper work processes and behav- iors. Be prepared to stop the videos at appropriate times to point out and discuss both proper and improper issues.
Instructors are also encouraged to locate additional audiovisual aids available on the internet, make personal videos, and take still pictures related to the HVAC/R trade and add them to the PowerPoint® presentations throughout the program.
The Lesson Plan for this module is divided into four 2.5-hour sessions.
This time includes 10 minutes for administrative tasks and a 10-minute break per session.
