20. Insulation for piping and equipment
Piping and equipment should be insluated according to the insulation class, operating temperature and insulation thickness stated in the P&ID and Data sheets.
All insulation shall be covered with weather protection designed and installed to prevent ingress of water during normal operation.
Types of Insulation
1) Hot Insulation – The Hot insulation installation will cover the following two major categories in Hot Insulation for Piping & Hot Insulation for Equipment
2) Cold Insulation – Cold insulation installation will cover the following two major categories. Cold Insulation for Piping & Cold Insulation for Equipment
3) Weatherproofing Installation (Insulation Jacketing) – All external surface of insulation shall have a weather barrier finish to keep insulation dry and provide mechanical protection
4) Plug Installation – The use of inspection plugs is applicable only for hot insulated surface of piping & equipment

배관, 기계 보온작업에는 작업대 준비가 사전에 충분히 검토되고 고려되어야 합니다.
보온작업이라는 것이 후속작업으로 이미 구성된 기계장치에서 작업하기 때문에 비계 설치는 필수적입니다.
보온작업이 계획되어 있으세요? 작업대 확인하세요~!!^^
한가지 더, Pre-Comm. 이 진행되고 있다면 작업 전 점검 및 작업계획 수립이 선행되어야만 합니다.
감사합니다.
