(2)保溫層：采用硬質聚氨酯泡沫塑料。(3)保護殼：采用高密度聚乙烯或玻璃鋼。(4)滲漏報警線：制造高溫預制直埋保溫管時，在靠近鋼管的保溫層中，埋設有報警線，一旦管道某處發(fā)生滲漏，通過線的傳導，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)運行。防腐，絕緣性能好，使用壽命長。除外生產(chǎn)的高溫預制直埋保溫管，均設有滲漏報警線，一旦管道某處發(fā)生滲漏，通過報警線的傳導，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)的運行，國內報警線，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.

The national standard black jacket thermal insulation pipe is selected in size, and the precast polyurethane heat preservation steel pipe is composed of a working steel pipe, a rigid polyurethane foam foam insulation layer and a high-density external protective pipe. Polyurethane foam products are widely used in urban central heating and cooling engineering, with remarkable energy saving effect, convenient construction and installation, and good economic and social benefits. The structure of prefabricated polyurethane insulation steel pipe is mainly composed of three parts.
層：工作鋼管層。根據(jù)輸送介質的技術要求分別采用有縫鋼管、無縫鋼管、雙面埋弧螺旋焊接鋼管第二層：聚氨酯保溫層。用高壓發(fā)泡機在鋼管與外護層之間形成的空腔中一次性注入硬質聚氨酯泡沫塑料原液而成，即俗稱的“管中管發(fā)泡”第三層：高密度聚保護層。 由于涂敷內涂層時，鋼管的加熱溫度必須在所使用熔結環(huán)氧粉末涂料所要求的溫度范圍內，但高溫度不得超過275℃。該作業(yè)線設計防腐生產(chǎn)規(guī)格為 φ60mm～φ426mm的鋼管，選擇中頻功率時，通過計算我們選擇使用的中頻功率為250kw，并選用了多圈單閘中頻感應圈，在試運行中用遠紅外測溫儀對鋼管溫度進行測量，發(fā)現(xiàn)使用多圈單閘中頻感應圈存在一定的缺點，鋼管局部溫度過高或高低，使鋼管加熱溫度不勻，影響內防腐。，8、以求生存，以求發(fā)展，向要效益，環(huán)氧白陶瓷防腐螺旋鋼管廠家了市場，房地產(chǎn)投資93387億元，即可進行涂裝。
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.

The construction technology of black jacket insulation pipe polyurethane foam is composed of two components. During the construction, the two components enter the spraying machinery and mix and spray out, which is in the form of fog. It is foamed and solidified in one minute. This kind of material was introduced in recent years and used for building thermal insulation and waterproof. After three years of use, it has more understanding, advantages and wide application range. -During construction, the immersion of underground water and rain water shall be avoided. If the end is accidentally immersed in water, drying treatment shall be carried out before connecting the jacket.
