The size and structure of the pipe for laying the heat-tracing cable is exactly the same as that of the ordinary heat preservation pipe. The outer wall of the special heat-tracing cable scarf steel pipe is laid in parallel with it, and the point heat is used to heat the medium through the steel pipe. At the moment when the cable is energized, the resistance of the PTC memory material in the cable increases gradually with the increase of temperature, so the working current and electrothermal power also gradually decrease, until the heating power compensates the heat loss of the system and makes the temperature of the system in a stable state. When the ambient temperature decreases, the cable power increases automatically and the loss is compensated automatically, so that the system is in balance at the new temperature.

Provide caring materials for sanitation workers, couriers, taxi drivers, as well as community service providers, volunteers and other grass-roots front-line workers. The warm package will be configured with different combinations of labor protection products according to different working environments and seasons.

The steel pipe thermal insulation anti-corrosion production line built by one-step molding of polyethylene thermal insulation pipe has a high degree of automation and the quality of the adiabatic anti-corrosion coating is fully in line with the national standards. The outer wall of the special heating cable scarf steel pipe is laid parallel to the pipe, and the point heat is used to heat the medium through the steel pipe. How many protective coatings are used (such as high density polyethylene and fiberglass protective coating), but the integrity, tightness and waterproof of the joint must be obtained. The thermal insulation material is selected for the insulation layer of the working steel pipe, and the thermal insulation effect is good. The use of directly buried heating pipeline technology indicates that the development of heating pipeline technology has entered a new starting point.
Not as dull as the black suit, this low-key light color, put on behind a bit more gentle and temperament, a little higher affinity, right? The inside is simply matched with a solid color backing or t-shirt, and the bottom is a pair of white suit pants. in order to increase the exquisite styling, like this blogger uses a colored scarf to tie on his bag, which attracts the eye without losing his taste.
