聚氨酯保温钢管在生产过程中应执行的标准有哪些?

来源:http://www.rrhsf.com 日期:2019-08-19 发布人:admin
1、使用了导热系数低、隔热性能好的硬质聚氨酯作为隔热材料,具有优异的隔热性。
1. The rigid polyurethane with low thermal conductivity and good thermal insulation is used as thermal insulation material, which has excellent thermal insulation.
2、正常运行后130℃的水输送到40公里以外时,降温仅为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、有很强的防水和耐腐蚀能力,不需附设管沟,可直接埋入地下或水中,施工简便迅速,综合造价低。
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、在低温条件下也具有良好的耐腐蚀和耐冲击性,可直接埋入冻土层。
4. It also has good corrosion resistance and impact resistance at low temperature, and can be directly buried in frozen soil.
5、预制保温管使用了耐腐蚀性的(HDPE:高密度聚乙烯)外套管,不受生物和化学腐蚀的影响。
5. Prefabricated insulating pipes use corrosion-resistant (HDPE: HDPE) outer casing, which is not affected by biological and chemical corrosion.

6、可根据用户需要提供DN20~DN1200之间各种管径及保温厚度的管材和相配套的管件(弯头、三通、变径管、固定节等)
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、产品执行我国城镇建设行业标准CJ/T 114-2000和CJ/T 115-2001标准。
7. Product implementation of China's urban construction industry standards CJ/T 114-2000 and CJ/T 115-2001 standards.
8、为确保预制直埋保温管三位一体,发泡前钢管外表面处理,塑料管内表面电晕处理,其中除锈等级达到GB/T 8923-1998中Sa2.5的规定,外壳管内表面张力达到50达因/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、聚乙烯外护管采用高密度聚乙烯材料,辅以抗氧剂等各种助剂制成,并对原材料和产品质量进行严格检验,确保产品质量达到CJ/114-2000标准和直埋管外护管的技术要求,提高了外护管的整体质量。具体技术指标见下表。
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、公司配备有进口和国产高压发泡机、液压穿管机,提高了产品的整体质量。
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.
