The full name of polyurethane thermal insulation steel pipe: high-density polyethylene plastic external protection polyurethane foam prefabricated directly buried insulation pipe, from the transport medium, working steel pipe, polyurethane insulation layer, polyethylene plastic external protection pipe, through the equipment in turn to the outside. Under normal circumstances, the thickness of the insulation layer is generally less than 2 centimeters, and the common one is 5 centimeters. The polyurethane insulation layer is formed by injecting rigid polyurethane foam solution into the cavity formed between the steel pipe and the outer protective layer by a high-pressure foaming machine. It is commonly known as “tube-in-tube foaming process”. Its function is waterproof, thermal insulation and supporting the self-weight of the heating network. When the temperature of the conveying medium is-50 ℃-120 ℃, the rigid polyurethane foam is selected as the insulation layer.
Classification of thermal insulation steel pipes 1. Steel jacket steel composite thermal insulation steel pipe thermal insulation structure can be divided into two categories according to different sliding modes: internal 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 reflective layer, polyurethane insulation layer, outer steel pipe and external anti-corrosion layer. The inner sliding type thermal insulation steel pipe is composed of steel pipe with conveying medium + composite silicate or microporous calcium silicate + rigid polyurethane foam plastic + outer steel pipe + glass steel shell anticorrosion protective layer structure. The heat preservation treatment technology of all kinds of pipe joints is mature and the quality is reliable.

Pearl milk tea equipment sealing machine operation steps: 1, turn on the power supply, turn on the power switch on the panel, the indicator light is on, the thermostat is set to the predetermined temperature, and the green heating indicator is on. When the hot plate reaches the predetermined temperature, the red constant temperature indicator lights. After the sealing machine works, the electric heating device will continue to alternate in the state of heating and heat preservation, that is, green and red lights will be displayed alternately. 2. Put the plastic cup into the lower mold skateboard, push the lower die skateboard to a certain position by hand, press down the handle of the sealing machine to a relatively large stroke, and hold pressure for 1-2 seconds. Then slowly raise the handle and push it to the original position. 3. Take out the lower mold skateboard, take out the plastic cup, put it into the unsealed plastic cup, and proceed to the next cycle.
The service life can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying and overhead laying. Polyurethane thermal insulation pipe, full name: high-density polyethylene plastic external protection polyurethane foam prefabricated directly buried insulation pipe, by the transport medium, working steel pipe, polyurethane insulation layer, polyethylene plastic outer protection pipe, through the equipment to the outside.
About the packing. If you buy it, it should be vacuum-pumped and there are plastic covers on the outside, and it is installed in a foam incubator with antifreeze film on the outside and several layers. If the packing is simple, it is recommended to change to another one.
