Black jacket polyurethane foam insulation tube foam has good mechanical properties and insulation polyurethane insulation pipe application: polyurethane insulation pipe for indoor and outdoor pipes, central heating pipes, central air-conditioning pipe, chemical industry, and other industrial pipeline insulation and cold insulation works. Since the birth of polyurethane synthetic material in the 1930s, polyurethane foamed insulation pipe has been rapidly developed as an excellent thermal insulation material, and its application scope is becoming more and more widespread. It is also widely used in various heating, refrigeration, oil and steam transmission pipelines because of its cumbersome construction and remarkable energy-saving and anti-corrosion effect. It is widely used in various heating, refrigeration, oil and steam pipelines.
鋼管的選用：
Selection of steel pipe:
根據(jù)設(shè)計(jì)和客戶的懇求普通為：DN200以下選用無縫管，以上選用螺旋焊管和直縫焊管。鋼管表面經(jīng)過先進(jìn)的拋除銹工藝處置后，鋼管除銹等級(jí)可達(dá)標(biāo)準(zhǔn)中的Sa2級(jí)，表面粗糙度可達(dá)標(biāo)準(zhǔn)中R=12.5微米
According to the design and customer's request, the seamless pipe is usually chosen below DN200, and the spiral welded pipe and the straight welded pipe are selected above. After the surface of steel tube is treated by advanced rust removal technology, the grade of steel tube rust removal can reach Sa2 level in the standard, and the surface roughness can reach R=12.5 micron in the standard.

3、有很強(qiáng)的防水和耐腐蝕才干，不需附設(shè)管溝，可直接埋入公開或水中，施工煩瑣疾速，綜合造價(jià)低。
3. Strong ability of waterproof and corrosion resistance. It can be directly buried in open or water without additional pipe trenches. The construction is tedious and fast, and the comprehensive cost is low.
4、在低溫條件下也具有良好的耐腐蝕和耐沖擊性，可直接埋入凍土層。
4. It also has good corrosion resistance and impact resistance at low temperature, and can be directly buried in frozen soil.
5、預(yù)制保溫管運(yùn)用了耐腐蝕性的(HDPE：高密度聚乙烯)外套管，不受生物和化學(xué)腐蝕的影響。
5. Prefabricated insulating pipes use corrosion-resistant (HDPE: HDPE) outer casing, which is not affected by biological and chemical corrosion.
6、可根據(jù)用戶需求提供口徑之間各種管徑及保溫厚度的管材和相配套的管件(彎頭、三通、變徑管、固定節(jié)等)
6. Pipes with various diameters and insulation thicknesses and matching fittings (elbows, tees, variable diameter pipes, fixed joints, etc.) can be provided according to user's requirements.
7、產(chǎn)品執(zhí)行中華人民共和國城鎮(zhèn)樹立行業(yè)標(biāo)準(zhǔn)。
7. Implementing products to establish industry standards in cities and towns of the People's Republic of China.
8、為確保預(yù)制直埋保溫管三位一體，發(fā)泡前鋼管外表面處置，塑料管內(nèi)表面電暈處置，其中除銹等級(jí)抵達(dá)中Sa2.5的規(guī)則，外殼管內(nèi)表面張力抵達(dá)50達(dá)因/厘米。
8. In order to ensure the trinity of prefabricated directly buried insulating pipes, the outer surface of steel pipes before foaming and the inner surface corona of plastic pipes are disposed. Among them, the rule of Sa2.5 in the rust removal grade is reached, and the inner surface tension of the outer pipes reaches 50 dynes/cm.
9、聚乙烯外護(hù)管采用高密度聚乙烯材料，輔以抗氧劑等各種助劑制成，并對(duì)原材料和產(chǎn)質(zhì)量量中止嚴(yán)厲檢驗(yàn)，確保產(chǎn)質(zhì)量量抵達(dá)標(biāo)準(zhǔn)和直埋管外護(hù)管的技術(shù)懇求，進(jìn)步了外護(hù)管的整體質(zhì)量。細(xì)致技術(shù)指標(biāo)見下表。
