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.

One of the simplest way to tie the handle of the bag with a long scarf is to tie a random knot. This method is more suitable for silk scarves with colors, but in terms of color, it is best to choose the color that echoes with the bag. ▼

A few days before Liu Yifei was photographed having dinner with friends, another netizen ran into Liu Yifei in Sanlitun, Beijing. The fairy sister focused on choosing bags, and the picture was excellent. Liu Yifei was also dressed in black that day, but with an extra matching scarf, which retails for about 7,000 yuan and is also a prominent fashion item.

Laying the heat tracing cable in the pipe can avoid affecting the operation of the pipe network because of the pipe freezing. 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 z 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 temperature of the system in a stable state.

This little scarf is also red and white on both sides, but both sides are decorated with the same presbyopia pattern, and the little tiger pattern is also a small one, holding a classic round bag super cute, showing a vivid image of the zodiac tiger sitting firmly in the classic leather hard box. Congratulations on the Lunar New year.

Pure retro style matching is a more popular trend at present, using loose broken flower French shirt with denim high waist trousers and red Mary Jane shoes, the overall match is gentle and fresh, and the silk scarf accessories on the head is the finishing touch of the style.
