The tee should be welded to the steel pipe, and the opening of the branch pipe should be strengthened. Steam pipe directly buried FRP outer cover composite steam directly buried pipe 1 wrapped on the working steel pipe * layer thermal insulation material aluminum silicate fiber blanket 2 adding calcium silicate (tile shell) 3 on the aluminum silicate fiber blanket pouring polyurethane foam 4 after removing the mold to make FRP insulation pipe polyurethane foam on the glass steel pipe winding machine has good mechanical and thermal insulation properties, usually can withstand temperature 120 ℃ It can withstand 180 ℃ by modification or combination with other thermal insulation materials. Inorganic hard insulation layer: high temperature resistance, the interface temperature between the organic insulation layer and the foam is not carbonized. At present, there are many kinds of thermal insulation materials and pipes in the thermal insulation engineering market: prefabricated directly buried thermal insulation pipe, rubber-plastic thermal insulation pipe, polyethylene insulation pipe, high temperature prefabricated polyurethane thermal insulation pipe and so on.
And the plastering width on the inside of the hole should be consistent and the size of the head should not appear. Wuxi base is a comprehensive enterprise mainly engaged in the scheme design and construction of “heat insulation project, sound absorption project” and the processing of engineering materials such as “fire-proof and heat-resistant cloth (blanket)”. In China, our company is an early and systematic enterprise engaged in the research, development and production of “detachable thermal insulation sleeve engineering and fireproof and heat-resistant fiber”. In this field, our company is a professional manufacturer with “many construction cases, complete product varieties and large production scale” in China. To sum up, the anti-cold and anti-freezing work of the instrument removable soft insulation sleeve is particularly important.
For added convenience, consider travel bags that come with extra features and accessories designed specifically for children. Many bags have insulated compartments to keep snacks and drinks cool, while others feature detachable lunchboxes or water bottle holders. Look for bags with secure closures, such as sturdy zippers or buckles, to prevent any accidental spillage or loss of items. Additionally, some bags offer external attachment points to carry small toys or even a blanket, providing additional entertainment options during long journeys.
In fact, tents are not necessary for picnics, but the fairy mothers who take their children out have a small tent where they can have a rest when they are tired of playing and block the sun when the sun is strong. They can also bring a small blanket to prevent their children from catching cold when they fall asleep ~
Proceed from your own needs. Ceramic fiber has good properties of fire resistance, heat preservation, heat insulation and sound absorption, so it must have a clear direction first. For example, low-grade ceramic fiber blankets or fiber cotton can be selected for thermal insulation and sound absorption; fibreboards and modules of the corresponding grade should be selected according to the working temperature of the application environment for fire resistance and thermal insulation; and high temperature protection and fire prevention can choose ceramic fiber textiles and other derivative products.
Metal decorative mesh has the function of regulating light, temperature and low noise. It can be based on the utilization of the room and to be used to regulate the indoor light, in order to prevent direct glare. The metal decoration net of different texture can block the outdoor hot and cold atmosphere and excrete into the room at a certain level, especially in summer, it can be used to shade and insulate. Another function of metal curtains is to use them to reduce noise. Silk, plush and thin blankets are all good sound absorbing materials, which can better cut off the noise. Bamboo curtains and metal blinds can not only block the sun, but also ventilate. These two kinds of curtains are favored by people in summer.
