What is the first step when installing a repair clamp on a steel pipe?

• A. Apply a coat of paint
• B. Remove rust, scale, and any coating from the affected area
• C. Measure the diameter of the pipe
• D. Apply a pressure test

Answer: (B)

The first step when installing a repair clamp on a steel pipe involves removing rust, scale, and any coating from the affected area. This is critical because it ensures a clean surface for the repair clamp to properly adhere to the pipe. Any existing rust or coating can prevent the clamp from making a secure seal, which is essential for preventing leaks. By cleaning the area thoroughly, you allow the clamp to form a tight bond with the steel, ensuring that the repair is effective and durable. This preparation step is foundational to the integrity of the repair, and proceeding without it could lead to inadequate sealing and potential failure of the repair over time. Other steps like measuring the diameter of the pipe or applying a coat of paint are essential but are more relevant after ensuring a clean surface for the repair clamp. Applying a pressure test typically comes after completing installation and is part of the verification process to ensure the repaired area is functioning correctly.
