Final answer:
Cut grooving is a pipe preparation method that is designed for thick-walled pipes. It involves cutting a groove into the pipe to create a durable joint appropriate for high pressure and temperature conditions.
Step-by-step explanation:
Cut grooving is designed for thick wall or pipe with a heavy wall thickness. The correct answer to this question is C) Thick.
Cut grooving is a method used to prepare pipes for joining that involves cutting a groove into the end of a pipe. It is particularly suited for pipes with a heavy wall thickness because it provides a stronger, more durable joint. For pipes that have thin or flexible walls, other methods such as roll grooving might be more appropriate, which deforms rather than removes material.
Cut grooving is common in piping systems that need to withstand high pressure, temperatures, or are subject to heavy mechanical loads. These conditions are often met in industrial, commercial, or institutional building systems. Grooved piping systems also enable easier disassembly and reassembly, which is beneficial during maintenance or system reconfiguration.
