(2)保溫層：采用硬質(zhì)聚氨酯泡沫塑料。(3)保護殼：采用高密度聚乙烯或玻璃鋼。(4)滲漏報警線：制造高溫預(yù)制直埋保溫管時，在靠近鋼管的保溫層中，埋設(shè)有報警線，一旦管道某處發(fā)生滲漏，通過線的傳導(dǎo)，便可在專用檢測儀表上報警并顯示出漏水的準確位置和滲漏程度的大小，以便通知檢修人員迅速處理漏水的管段，保證熱網(wǎng)安全運行。防腐，絕緣性能好，使用壽命長。除中國外生產(chǎn)的高溫預(yù)制直埋保溫管，均設(shè)有滲漏報警線，一旦管道某處發(fā)生滲漏，通過報警線的傳導(dǎo)，便可在專用檢測儀表上顯示出保溫管道滲水、漏水的準確位置及滲漏程度的大小，以便通知檢滲人員迅速處理漏水的管段，保證供熱管網(wǎng)的安全運行，國內(nèi)報警線，有待補上這一空之。
(2) insulation layer: rigid polyurethane foam. (3) Protective shell: high density polyethylene or glass fiber reinforced plastic. (4) Leakage alarm line: when manufacturing high-temperature prefabricated directly buried insulation pipe, there is an alarm line embedded in the insulation layer close to the steel pipe. Once there is leakage in the pipeline, through the transmission of the line, the alarm can be given on the special detection instrument, and the accurate position and degree of leakage can be displayed, so as to inform the maintenance personnel to deal with the leaking pipe section quickly and ensure the safe operation of the heat supply network. Anticorrosion, good insulation and long service life. Except for the high-temperature prefabricated directly buried insulation pipes produced outside China, leakage alarm lines are set. Once there is leakage in the pipeline, through the conduction of the alarm line, the accurate position and degree of leakage of the insulation pipeline can be displayed on the special detection instrument, so as to inform the leakage inspection personnel to quickly deal with the leaking pipe section, ensure the safe operation of the heating pipe network, and give an alarm at home The line needs to be filled.

Layer: working steel pipe layer. According to the technical requirements of conveying medium, seamless steel pipe, seamless steel pipe and double-sided submerged arc spiral welded steel pipe are used respectively. The second layer: polyurethane insulation layer. The rigid polyurethane foam plastic is injected into the cavity formed between the steel pipe and the outer sheath by high-pressure foaming machine. The third layer is commonly called "tube in tube foaming": high density protective layer. As the internal coating is applied, the heating temperature of the steel pipe must be within the temperature range required by the fusion bonded epoxy powder coating used, but the high temperature shall not exceed 275 ℃. The design anticorrosion production specification of the operation line is When the medium frequency power is selected for the steel pipe with the diameter of 60mm ~ 426mm, the medium frequency power of 250KW is selected by calculation. In the trial operation, the temperature of the steel pipe is measured by the far-infrared thermometer. It is found that there are some shortcomings in using the multi circle single switch medium frequency induction coil. The local temperature of the steel pipe is too high or high, which makes the heating temperature of the steel pipe uneven Internal corrosion protection. In order to survive, develop and benefit, the manufacturer of epoxy white ceramic anti-corrosion spiral steel pipe has entered the market and invested 9338.7 billion yuan in real estate, which can be used for coating.
