The basic principle of uncompensated laying method is to heat the pipe to a certain temperature at first, then weld and fix the pipe, and then lower the temperature when the pipe is restored to the installation temperature. The mold can not be removed until the end of the pouring. It also has obvious social and economic benefits, and it is also a powerful measure for heating and energy saving. A brief introduction to the use of new Michigan heating and insulation seamless steel pipe according to the sliding mode, the thermal insulation structure of steel sleeve steel insulation pipe is divided into internal sliding type and external sliding type, and the inner sliding thermal insulation structure is composed of working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, heat insulation layer, stainless steel fastening steel strip, aluminum foil reflection layer, polyurethane insulation layer, outer steel pipe and external anti-corrosion layer. The sliding bracket and internal fixation in the steam pipe adopt the thermal insulation measures of special materials to prevent the occurrence of the thermal bridge, so that the temperature control of the outer anticorrosive coating is guaranteed.
2. Tightness test: when the pressure in the pipe is reduced to the working pressure, the weld is checked one by one around the weld with the hammer of 1kg. The steam directly buried steel sleeve steel insulation pipe is composed of steel pipe conveying medium, anticorrosive jacket steel pipe and ultra-fine glass cotton filled between steel pipe and jacket steel pipe, and can also be made of graphite, calcium silicate tile shell and filled polyurethane foam. The burying technology of steel casing (steel sleeve steel) is a new burying technology of waterproof, anti-leakage, anti-seepage and anti-pressure. it is a great breakthrough in the application of direct-buried laying technology in areas with high groundwater level. The primary problem of the protective pipe of the directly buried pipeline is the reliability of strict waterproofing. In addition, it is necessary to have good mechanical strength. Because of the high strength, the steel casing is connected by welding, and the reliability of waterproof sealing performance is very high. Its high temperature resistance is also incomparable to other external protective pipes.
After entering the field, the inspection should be carried out carefully, and the manufacturers producing directly buried insulation pipes must be investigated before construction, and the unqualified insulation pipes must be refused to use. 3, it is necessary to understand that the directly buried laying methods of heating pipes can be divided into two ways: compensated directly buried laying and uncompensated direct buried laying. In the design and construction, the steel sleeve steel insulation pipe of 377 heating steam insulation pipe works from the inside.
