The Contractor shall keep his working locatio
7、ns in a tidy condition and shall remove all his waste and surplus material from the site at the end of the contract or any other time when, in the opinion of Owner, said removal is necessary for safety of personnel or any other reason. 2.2 Preparation Prior to the installation of insulation all stee
8、l surfaces shall be dry, clean and free from grease, and dirt. Partially insulated surfaces shall be fully painted, and fully insulated surfaces shall be fully primed, in accordance with *-ED-N-0001. The installed Paint System must have an authorized acceptance certificate prior to the installation
9、of any insulation. 2.3 Testing Equipment which is to be hydrostatically pressure tested after installation shall not be insulated until such tests has been successfully completed. Equipment which has been successfully shop tested may be insulated prior to field test, except for joints made in the fi
10、eld. Piping is to be pressure tested before insulation is applied. 2.4 Extent of insulation a) Insulation is required for General heat conservation of equipment and piping above 70oC. On large surfaces insulation may be justified for lower temperatures. Personnel protection on surfaces with a temper
11、ature of 60oC or higher in areas where personnel contact is likely. Temperature stability of processes or products, e.g., to avoid condensation, solidification, or too high a viscosity. This may be required for any operating temperature. b) Each line shall be insulated separately; adjacent lines sha
12、ll not be enclosed by a common insulation cover. c) Insulation shall not be applied, except for personnel protection, to equipment and piping which are designed to emit heat or where cooling is required by the process e.g. piping to air coolers. d) Piping valves and flanges shall not be insulated ex
13、cept in steam service, traced or jacketed services or special cases where thermal overstressing would occur if not insulated. This includes flanged joints whose temperature/material combination is such that omission of insulation would overstress the bolts. e) Nameplates, thermo well bosses and pres
14、sure tapping shall be left clear of insulation. 2.5 Selection of Materials 保温应按照良好的工业实践中应用，并在完成时，业主应有一个整洁和 精致的外观满意度。 承包商应保持他的工作地点在一个整洁的状态，应在合同或其他任何时 候，移除了所有的废物和多余的材料，在业主的意见下，但排除必要的 人员安全或任何其他原因的情况。 2.2 准备 所有钢结构表面安装之前保温应干燥，清洁，无油脂和污垢。按照*- ED-N-0001 要求，部分保温表面表面和完全保温的表面都应满刷油漆， 。 任何保温前，已完成涂刷的油漆系统都有接受检查验收证
15、书。 2.3 测试 保温应在设备完成安装并成功完成静水压力测试后进行。 先期已在工厂 完成了测试的设备，现场施焊的焊道应被保留，以便完成现场的测试。 管道应于保温之前进行压力试验。 2.4 保温范围 a. 保温应用于 设备和管道的总热量持续高于 70。 在大型表面保温可能是合理 的较低温度。 给予 60以上温度的区域人员保障，因为在那里可能会接触到表 面。 用于过程中或产品的温度稳定，例如，温度稳定性，以避免凝结， 凝固，或粘度太高。这可能需要的任何操作温度。 b. 每行应单独隔离保温; 相邻行不应由一个共同的保温罩包围。 c. 除了人员保护，保温不适用于以下的设备和管道：其目的是为了释放 热量，或是由工艺过程如管道所需的冷却空气冷却器。 d. 管道阀门和法兰不应保温，除了以下情况：蒸汽，伴管或夹套管，或 不保温将发生热膨胀的特殊保温情况。 这包括法兰接缝，温度/材料连 接处的应力螺栓，其保温应被省略掉。 e. 保温后，铭牌，热通道突起和压力攻丝塞子应保持畅通。 2.5 材料选用 * Project
