Mortise heater for heating up stringy oil-petroleum products

 

Mortise heaters is used to heat up stringy oil-petroleum products (flux, bitumen) in heat insulating vessels up to 170°C and to keep their temperature according specified limits.

Exploitation conditions depend on climatic factors in accordance with State Standard 14150-64, ambient temperature is from -45°C up to +40°C, relative humidity is 80% when the temperature is 20°.

The heater consists of flange(1) with pipe (sometimes it can be 3 pipes) (2), there are tubular electric heaters inside of it(3). A protective lid(4) is fixed to flange, which protect contact sets of heaters from atmospheric effects. A Feed cable is connected to heaters through a branch pipe. The Heater HB-18, HB-2 is fixed to frame of a vessel with the help of welding. It’s necessary to foresee a stand to prevent deformation of a pipe in process of exploitation.
