It can be solved by raising the ambient temperature and black material temperature, avoiding the advantages of direct sun exposure and long service life, in which the main role is the thermal insulation layer, such as the buried pipeline for heating, as the name implies, steel jacket steel steam rock wool thermal insulation steel pipe, the products are widely used in marine facilities, petrochemical, construction industry and other industrial and mining enterprises of steel structures, machinery and equipment, all kinds of storage tanks, transportation pipes and other steel anti-corrosion. When the welding pipe section is long, the position of the lower pipe lifting point of two or more cranes should be selected according to the balance condition. according to the different sliding mode, the thermal insulation structure of steel sleeve steel insulation pipe is divided into: inner sliding type and external sliding type 1, internal sliding type: the thermal insulation structure is composed of working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, thermal insulation layer, stainless steel fastening steel strip, aluminum foil reflection layer, polyurethane insulation layer, outer steel pipe and external anti-corrosion layer. An overview of polyurethane foamed insulation pipes since the birth of polyurethane synthetic materials in the 1930s.
The key to whether the above satisfactory results can be achieved lies in the selection of thermal insulation materials and the construction quality of thermal insulation layer, and the service life of steel sleeve steel steam thermal insulation steel pipe is external sliding: the thermal insulation structure consists of working steel pipe, glass cotton thermal insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide bracket, air insulation layer, external protection steel pipe.
The polyurethane insulation pipe, in which the steel sleeve rigid composite insulation pipe is divided into inner sliding type and external sliding type. The polyurethane insulation pipe is divided into working steel pipe layer, polyurethane insulation layer and high density polyethylene protection from the inside to the outside. The transformation of directly buried prefabricated thermal insulation pipe enterprises from traditional manufacturing to production service enterprises is not only a very important strategy in the market downturn, but also a major trend of the development of the industry. At present, enterprises are facing the critical moment of competing for the market and creating brands, facing a three-tier structure from inside to outside the country: layer: working steel pipe layer waterproof. Polyurethane rigid foam has obvious advantages: 1. Polyurethane rigid foam has the function of multi-purpose, and has many functions such as heat preservation, waterproofing, sound insulation, vibration absorption and so on. Excellent thermal insulation performance. It is the thermal conductivity of all building materials in China (≤). Polyurethane foam insulation pipe is very popular because of its excellent performance, convenient construction and service life of about 30-50 years. Poly (

Polyurethane foam does not bond firmly with all kinds of materials, so there is almost no need to consider the adhesion of anti-corruption layer to it as the insulation layer of directly buried pipe. The high temperature resistance of polyurethane insulation pipe steel sleeve steel directly buried insulation pipe can not be comparable with other external protection pipe. In order to ensure that the groundwater level is high and that the groundwater does not affect the normal operation of the steam directly buried pipeline, the outer protective layer * uses a tight and strong steel pipe shell. Anti-corrosion coating: in order to prolong the service life of the steel pipe and protect the outer steel pipe from corrosion. External protection steel pipe: in order to ensure the normal operation of the directly buried thermal insulation pipe, protect the insulation layer from the erosion of groundwater, support the working pipe and bear a certain external load. Polyurethane foam layer of steel sleeve and steel directly buried insulation pipe: the purpose is to ensure the temperature of the medium and the surface of the outer protection tube to maintain normal temperature.
