Customization of LEUB buried guide bracket drawings for long-distance low-energy insulation pipe supports for buried steam pipelines

Description :

　　Consultation on Long distance Low energy Insulation Pipe Support Technology: Installing insulation rings in the two parts above the buried steam pipeline is to avoid the formation of a hot channel between the working steel pipe and the outer steel pipe through sliding brackets and steel ring plates, which can cause excessive expansion of the outer steel pipe and shorten the service life of the anti-corrosion layer of the outer pipe. The insulation ring mainly plays a role in insulation and support in directly buried steam pipelines. The semi-circular insulation ring is placed between the working steel pipe and the sliding bracket to provide insulation. The semi-circular insulation ring should have sufficient compressive strength to withstand the three weights of the working steel pipe, insulation layer, and working medium without deformation, in order to ensure the normal operation of the working steel pipe. The pipe clamp is equipped with a hard insulation layer and a soft insulation layer. For pipes with a diameter below DN500, the thickness of the soft insulation layer is 20-30mm, the thickness of the hard insulation layer is ≥ 50-60mm, and for pipes with a diameter above DN500, it is ≥ 60-100mm. When the temperature is t=250 ℃, the thermal conductivity is ≤ 0.2W/m.k. To solve the above problems and ensure that the new insulation pipe bracket meets the long-term and energy-saving operation of steam pipelines. The steel sheathed steam insulation pipe is composed of external protective steel pipe plus steel pipe anti-corrosion, polyurethane foam insulation layer and internal working steel pipe. At present, direct buried steam pipelines have been widely used in China's urban centralized heating network, and the technology is becoming increasingly mature. Various regions have accumulated rich experience in engineering practice
