What type of tape is used to wrap steam tracing lines?

• A. Dac Tape
• B. Masking Tape
• C. A-tape
• D. Electrical Tape

Answer: (C)

Tape used on steam tracing lines must withstand high temperatures and stay bonded to insulated surfaces in a humid, steam-rich environment. A-tape is designed for heat-traced piping, with a high-temperature adhesive and material that adheres well to insulation and remains stable under steam exposure. This ensures the tracing is secured and the insulation remains sealed, helping maintain the intended heat delivery. Other tapes lack the necessary heat resistance or durability: masking tape and electrical tape can fail or deteriorate in high temperatures, and Dac Tape may not have the required temperature rating or long-term adhesion.
