      聚氨酯保溫鋼管在生產過程中應執(zhí)行的標準有哪些?

      來源:http://www.qndr49.cn 日期:2019-08-19 發(fā)布人:admin
      1、使用了導熱系數(shù)低、隔熱性能好的硬質聚氨酯作為隔熱材料,具有優(yōu)異的隔熱性。
      1. The rigid polyurethane with low thermal conductivity and good thermal insulation is used as thermal insulation material, which has excellent thermal insulation.
      2、正常運行后130℃的水輸送到40以外時,降溫僅為1℃左右。
      2. When water is transported to 40 kilometers away from 130 C after normal operation, the cooling rate is only about 1 C.
      3、有很強的防水和耐腐蝕能力,不需附設管溝,可直接埋入地下或水中,施工簡便迅速,綜合造價低。
      3. It has strong waterproof and corrosion resistance. It can be directly buried in underground or water without additional pipe trenches. It is simple and quick to construct and has low comprehensive cost.
      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、預制保溫管使用了耐腐蝕性的(HDPE:高密度聚乙烯)外套管,不受生物和化學腐蝕的影響。
      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)用戶需要提供DN20~DN1200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 between DN20 and DN1200 and matching fittings (elbows, tees, variable diameter pipes, fixed joints, etc.) can be provided according to user's needs.
      7、產品執(zhí)行我國城鎮(zhèn)建設行業(yè)標準CJ/T 114-2000和CJ/T 115-2001標準。
      7. Product implementation of China's urban construction industry standards CJ/T 114-2000 and CJ/T 115-2001 standards.
      8、為確保預制直埋保溫管三位一體,發(fā)泡前鋼管外表面處理,塑料管內表面電暈處理,其中除銹等級達到GB/T 8923-1998中Sa2.5的規(guī)定,外殼管內表面張力達到50達因/厘米。
      8. In order to ensure the trinity of prefabricated directly buried insulating pipes, the external surface treatment of steel pipes before foaming and the corona treatment of the inner surface of plastic pipes are carried out, in which the rust removal grade is up to Sa2.5 stipulated in GB/T 8923-1998, and the inner surface tension of shell pipes is up to 50 dynes/cm.
      9、聚乙烯外護管采用高密度聚乙烯材料,輔以抗氧劑等各種助劑制成,并對原材料和產品質量進行嚴格檢驗,確保產品質量達到CJ/114-2000標準和直埋管外護管的技術要求,提高了外護管的整體質量。具體技術指標見下表。
      9. Polyethylene outer protective pipe is made of high density polyethylene material, assisted by various additives such as antioxidants, and the quality of raw materials and products is strictly checked to ensure that the product quality meets the CJ/114-2000 standard and the technical requirements of directly buried outer protective pipe, thus improving the overall quality of outer protective pipe. Specific technical indicators are shown in the table below.
      10、公司配備有進口和國產高壓發(fā)泡機、液壓穿管機,提高了產品的整體質量。
      10. The company is equipped with imported and domestic high-pressure foaming machine and hydraulic pipe-piercing machine, which improves the overall quality of products.
