Laying the heating cable in the material can avoid affecting the operation of the pipe network because of the pipe freezing. The pipe for laying the heat-tracing cable has the same size and structure as the ordinary heat preservation pipe, and the outer wall of the special heat-tracing cable scarf steel pipe is laid parallel to it, and the point heat is used to heat the medium through the steel pipe. The heating power zui of the cable is large at the moment when the cable is energized, and 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 heat loss of the heating power compensation system makes the system temperature 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. This compensation heating method is efficient and energy-saving.
Dressed in black, simple and high-end, but easy to appear dull and serious, add a pair of exaggerated red earrings, and then tie a small red and white scarf on the bag to echo, you can easily break the dull feeling, appear bright and high-end, so that the overall wear becomes more attractive.
Problems that should be paid attention to in the design and construction of polyurethane thermal insulation directly buried heating pipe: OK. 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. The heating power of the cable is large at the moment of just electrification, and 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 heat loss of the heating power compensation system 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 can be balanced at the new temperature. This compensation heating method is efficient and economical.
Put it on the neck can enhance the point of view, if your cervical vertebra is not good, it can also play an appropriate role of protection, when you feel the neck is more stuffy, you can put the silk scarf on the bag, let the silk scarf become the accessories on the bag.
6. The joint shall be foamed and insulated on the spot. 7. The welding of jacket pipe should follow the principle of perfecting means and strengthening acceptance. two。 The construction operation of casting method should meet the following provisions: 1) the sundries and oil stains on the joint pipe should be removed before welding. 8. Sand filling, soil return 9. Engineering acceptance problems that should be paid attention to in the design and construction of polyurethane thermal insulation directly buried heating pipe: OK. 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. When the heating power of the cable is just turned on, 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 heat loss of the heating power compensation system makes the temperature of the system in a stable state.
The small printed scarf, which is mainly soft and delicate, is also an iconic accessory in modeling in the hot summer. A mother who is afraid of heat can tie it to the belt of her bag and leave a light “little tail” to dance with the wind. Far more romantic than monotonous and stodgy bags.
Tip 5: really do not want to wear “red” sweaters, coats, but also want to touch the joy of the New year, that can also be through the “red items” to decorate the whole set of matching! Red scarf, red hat, red shoes, red bag, red cell phone case. Even if the whole body is covered with the basic style of frigid style, even if you commute every day wearing “rigorous workplace attire”-dull and boring dark color matching, as long as a little dress up! A touch of red items can also make you the focus of your moments in winter!
