Pipe prepping in pipefitting refers to the process of preparing pipes for installation or welding by cleaning, cutting, or grinding a 37.5° angle onto the edge of the pipes to eventually fit the pipes together and set up a butt ready for a welder to come in and weld the two pipes together. This is crucial to ensure that the pipes are deburred from any rough edges and that the pipes are ready to be welded or joined together. Additionally, this makes sure that the dimensions of the pipework are all accurate. Pipefitters perform pipe prepping in order to be successful in installing strong pipework that is leak free.This is vital as there could be liquids, gasses or other materials under pressure. The main tool that pipefitters use when performing this task is the angle grinder. Before performing this task I need to ensure that I prepare the workshop and wear all of the appropriate PPE. Next, I inspected the workshop for all tripping/slipping hazards. Additionally, I inspected the angle grinder to ensure that the grinder was fit for use and was in good condition to complete this job. Once the angle grinder and the workshop were all inspected and checked that they were in good condition to prep the required pipes. First, I securely clamped the pipe into an engineer's vice so that I can work on the pipe without the pipe coming loose or moving around while preparing the pipe. This reduces the risk of the pipe slipping and causing any damage to the grinder or any accidents from occurring that may result in injury to myself or any other workers within the workshop. If I was required to cut the pipe to a specific dimension first, I would attach the cutting disc onto the angle grinder and then mark it out using a piece of chalk, marker pen, pipe wrap and a ruler/tape measure. Once I had properly marked out the pipe I could then get ready to start using the grinder to cut the pipe. Before this, I made sure that the grinder was in a good condition and that the grinder was de-isolated while inspecting the grinder so that I was safe. When starting to cut the pipe using the grinder, I slowly cut the pipe only a couple of mm through the pipe and worked my way up the marked out line as straight as possible. Once I had fully cut into the pipe all the way around I could then focus on cutting through the remaining pipe material. Next, I needed to ensure that the disc in the angle grinder was the grinding disc and not the cutting disc.

Job 2

Once all of the previous steps had been completed, I could then proceed to start working and preparing the pipe. Firstly, I needed to take off all of the rough edges of the pipe using the angle grinder. This could also be called ‘deburring’. Once the pipe had been deburred, I started to prep the pipe using the angle grinder. To do this I held the grinder at a slight angle to the material around 37.5° and applied just enough pressure to slowly cut the material as I moved the angle grinder round the pipe which will eventually create a smooth edge around the pipe edge. To check that I had prepped the pipe properly I could use a prep gauge to ensure that the angle of the prep was correct. After I had correctly prepped the pipe all around the edge, I then used the internal and external grinder flat to the surface of the pipe to ‘clean’ the pipework up. This would make it easier for any fittings of flanges to be connected to the pipework if required. Finally, I checked the edge of the pipework and the surface of the pipe for any rough edges that need to be filled to remove any deformities.

**Assessment Activities:**1. **Practical Demonstration:** - The learner will demonstrate their ability to interpret drawings, plan and execute pipefitting tasks, and complete a series of practical tasks such as cutting, threading, welding, and installing pipework. - The assessor will observe the learner during these tasks to ensure proper techniques and safety practices are followed.2. **Observation:** - The assessor will continuously observe the learner's performance throughout the assessment period, taking note of their adherence to safety protocols, efficiency, and accuracy in executing tasks.3. **Written Documentation:** - The learner will be required to document the process of their tasks, including planning, execution, inspection, and testing results. - This documentation will be reviewed to ensure thoroughness and accuracy.4. **Oral Questioning:** - The assessor will ask the learner a series of questions related to the tasks performed, focusing on the reasoning behind their choices, understanding of procedures, and knowledge of safety practices. - The learner's responses will provide insight into their depth of understanding and ability to apply theoretical knowledge practically.**Assessment Schedule:**1. **Initial Briefing:** - An initial meeting will be held to brief the learner on the assessment objectives, criteria, and schedule. The learner will be provided with all necessary documents and instructions.2. **Practical Demonstration and Observation:** - The learner will be given a series of tasks to complete within a specified timeframe. The assessor will observe and take notes throughout this period.3. **Written Documentation Submission:** - The learner will submit their written documentation of the tasks performed, including all inspection and testing results.4. **Oral Questioning Session:** - A session will be scheduled for the assessor to ask the learner questions about their tasks and procedures. This may be conducted immediately after the practical tasks or at a later scheduled time.5. **Feedback and Results:** - The assessor will provide feedback on the learner's performance, highlighting strengths and areas for improvement. The results of the assessment will be communicated to the learner.**Resources Required:**- Access to a workshop or site with necessary tools and equipment for pipefitting tasks.- Isometric drawings and piping schematics.- Materials for pipefitting (pipes, fittings, valves, flanges, etc.).- Personal protective equipment (PPE).- Documentation materials (notebooks, forms for recording results, etc.).**Assessment Evidence:**- Completed practical tasks and observations.- Written documentation and records of inspection/testing.- Responses to oral questioning.**Conclusion:**This assessment plan for Unit IPS04 ensures that the learner demonstrates a comprehensive understanding and practical ability in pipefitting techniques and practices, adhering to industry standards and safety regulations. The combination of practical demonstration, observation, written documentation, and oral questioning provides a thorough evaluation of the learner's competence.
