Polyurethane directly buried thermal insulation pipe factory price polyurethane thermal insulation directly buried heating pipe design and construction should pay attention to: 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 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 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.
Its overall shape is a bit like a semi-oval. I think it is especially suitable for the back in winter. Take off the scarf and gloves indoors and put them into the canvas bag. The bag will look better when held up.
Recently, Song Zhiya was picked out by South Korean netizens to wear multiple sets of clothes as counterfeits, wearing fragrant grandma short sleeves, Saint Laurent imitation leather coat, swimsuit, scarf and designer bags are not authentic.
The small bag is curved on the back, quiet and charming. If you pay special attention to it, decorate it with a silk scarf to show femininity and dignity. All black cool matching suit, the fashion point is the bag.
Several groups of silk scarves are recommended, and the most interesting one is this bag-style scarf tie method. In the cool spring, in addition to the decoration, put on a silk scarf to the bag, colorful and beautiful colors, just like spring, make people feel beautiful, fashionable and good-looking.
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.
