2 Scope and design principle of insulation

绝热范围和设计原则

2.1 Heat insulation保温

1.Heat insulation, in general, is used for equipment and piping which the operating temperature is 50~850℃, except for the place where heat loss is required. If the amount of heat loss is strictly limited, the insulation is fully used even though operating temperature is lower than 50℃. The insulation is also considered.

保温一般应用在操作温度在50~850℃的设备和管道上，要求有热损失的地方除外。当需要严格限定热损失量时，采用充分保温，即使操作温度低于50℃，也要考虑。

2.External insulation is not required for equipment and piping with refractory or insulation lining, except that the metal temperature must be controlled.

当设备和管道带有耐火材料或保温材料衬里时，不需要外部保温，金属温度必须被控制时除外。

2.2 Scald protection人身防护

The scald protection will be provided for the operating temperature above 60℃, non-insulated equipment and piping in the following areas. The operators may occasionally touch with these areas during operation.

人身防护应用于操作温度在60℃及以上，下述操作区域内不保温的设备和管道上，因操作人员作业时可能会偶然与这些区域接触。

1.Within 2100mm high from ground or floor.

从地面或楼面2100mm高以内。

2.Within 750mm beyond the platform or walkway edge.

超出平台或走道边缘750mm以内的距离。

3. When the heat need to be consumed, the shielding or baffle plate can be used for scald protection.

当需要消耗热量时，护罩或挡板也可用来代替人身防护。

2.3 Cold insulation保冷

The cold insulation is applied for the equipment and piping which operating temperature is lower than 10℃, except for the equipment and piping that heat-absorbing is required.

保冷应用于操作温度低于10℃的设备和管道上，需要吸热的设备和管道除外。

2.4 Anti-condensation防结露

When the operating temperature is higher than 10 but lower than ambient temperature, the moisture condensation of the equipment and piping surface will produce the following harmful effects.

防结露应用于操作温度高于10℃，又低于环境温度时，且设备和管道湿气冷凝表面将产生下述有害影响时。

1.When the condensation and dropping liquid will be harmful for the electrical facilities.

表面冷凝、滴液对电气设施有危害时。

2.When the condensation and dropping liquid will be harmful for some equipments.

表面冷凝、滴液对某些设备有危害时。

3.When the surface condensation makes the staff uncomfortable.

表面冷凝使工作人员不舒服。
