Light beige printed short-sleeved t-shirt with khaki shorts, full of male style and very aging, replaced with overalls bags, scarves and short boots, casual and fashionable. Steam transmission insulation pipe is also called steel sleeve steel steam insulation pipe, which is composed of working steel pipe, complex insulation layer and external protection steel pipe. The insulation layer plays the role of thermal insulation, but the steel pipe has no anticorrosive effect, so the working steel pipe and outer protective pipe will be painted with anticorrosive coating to play the role of anticorrosion. Generally speaking, the steam transmission insulation pipe is a kind of anticorrosive and thermal insulation steel pipe made of many kinds of materials. The price of internal and external sliding steel sleeve steel steam thermal insulation steel pipe is sold directly, the steel sleeve steel directly buried thermal insulation pipe is composed of working steel pipe, insulation layer, rolling guide pipe bracket, outer casing (steel pipe) and anti-corrosion coating, and the thermal insulation material is tied on the working steel pipe. rely on the rolling guide pipe support in the jacket tube integral thermal expansion movement, so it does not damage the insulation layer, the fixed bracket is built-in fixed bracket The huge reinforced concrete pier which does not need the original “three-way fixed bracket” is an ideal way for steam pipe laying. After years of use practice and the relevant testing center testing service life can reach more than 30 years. According to the different sliding modes, the insulation structure of steel sleeve steel steam insulation pipe can be divided into the following two types of The protective agency is incomparable. In areas with high groundwater level, in order to ensure that groundwater does not affect the normal operation of directly buried steam pipelines, the outer protective layer * uses solid and airtight steel pipe shell steel sleeve steel insulation steel pipe as an important building material in real life. It has been widely used in some different buildings, but this kind of insulation pipe can effectively ensure the temperature of a place. In fact, the insulation tube has been recognized by more and more people in the process of transportation, installation and use, so what is its internal structure? In fact, the steel jacket steel insulation steel pipe * layer structure is the working steel pipe layer, this structure is completely based on the actual needs of customers to design the surface of the steel pipe is usually treated by the rust removal process. The thermal insulation patching of the steel sleeve steel insulated steel pipe shall be carried out after the installation of the pipe is completed and the flaw detection inspection and strength test are qualified. The quality of the filling shall meet the design requirements, and each repair shall have an inspection record. The waterproof cap or waterproof coating that needs to be removed should be removed before patching. The patching of steel sleeve steel insulation steel pipe should be closely connected with the insulation layer of straight pipe segments or pipe fittings on both sides, and the gap should be filled with elastic thermal insulation material. For the directly buried steam thermal insulation steel pipe with rigid composite thermal insulation structure, when bonding the protective cushion, the surface of the working pipe at the patch should be preheated, and its quality should reach the St2 level specified in the current national standard “Surface corrosion grade and derusting grade just before painting” GB/T8923. If the steel sleeve steel insulation pipe section has been soaked in water, the soaked thermal insulation material should be removed or dried before the thermal insulation patching can be carried out.
