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.

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。
