聚氨酯直埋管的九特性能
Nine Characteristic Properties of Polyurethane Direct Buried Pipe
聚氨酯直埋管是由钢管玻璃钢内护套玻璃钢外壳构成,由保送介质的钢管及聚氨酯硬质泡沫塑料保温层高密度聚乙烯外套管严密结合而成,聚氨酯直埋管的功能特点如下:
Polyurethane direct buried pipe is composed of FRP inner sheath of steel pipe and FRP outer shell. It is made up of steel pipe with delivery medium and high density polyethylene outer sleeve with rigid polyurethane foam insulation layer. The functional characteristics of polyurethane direct buried pipe are as follows:
1.运用了聚氨酯直埋管导热系数低隔热功能好的硬质聚氨酯作爲隔热资料,具有优异的隔热性。
1. The rigid polyurethane with low thermal conductivity and good thermal insulation function is used as thermal insulation material, which has excellent thermal insulation.
2.正常运转后130℃的水保送到40公里以外时,降温仅爲1℃左右。
2. When the water conservation at 130 C is delivered to 40 kilometers away after normal operation, the cooling rate is only about 1 C.
3.聚氨酯直埋管运用了耐腐蚀性的(HDPE:高密度聚乙烯)外套管,不受生物和化学腐蚀的影响。
3. Polyurethane direct buried pipe uses corrosion-resistant (HDPE: HDPE) outer casing, which is not affected by biological and chemical corrosion.
4.聚氨酯直埋管有很强的防水和耐腐蚀才能,不需附设管沟,可间接埋上天下或水中,施工简便迅速,综合造价低。
4. Polyurethane direct buried pipes have strong ability of waterproof and corrosion resistance. They can be buried indirectly in the world or water without additional pipe trenches. The construction is simple and rapid, and the comprehensive cost is low.
5.在高温条件下也具有良好的耐腐蚀和耐冲击性,可间接埋入冻土层。
5. It also has good corrosion resistance and impact resistance at high temperature, and can be buried in frozen soil indirectly.
6.产品执行中华人民共和国城镇建立行业规范CJ/T114-2000和CJ/T115-2001规范。
6. The product implements CJ/T114-2000 and CJ/T115-2001 for the establishment of industry standards in cities and towns of the People's Republic of China.

7.爲确保聚氨酯直埋管三位一体,发泡前钢管表面面抛丸处置,塑料管内外表电晕处置,其中除锈等级到达GB/T8923-1998中Sa2.5的规则,外壳管内外表张力到达50达因/厘米。
7. In order to ensure the trinity of polyurethane buried pipe, shot blasting treatment on the surface of steel pipe before foaming and corona treatment on the surface of plastic pipe, the grade of rust removal reaches the rule of Sa2.5 in GB/T8923-1998, and the external tension of shell pipe reaches 50 dyne/cm.
8.可依据用户需求提供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)
8. Pipes with various diameters and insulation thicknesses between DN20 and DN1200 and matching fittings (elbow three-way variable diameter pipe fixed section, etc.) can be provided according to user's requirements.
9.聚氨酯直埋管采用高密度聚乙烯资料,辅以抗氧剂等各种助剂制成,并对原资料和产质量量停止严厉检验,确保产质量量到达CJ/114—2000规范和直埋管外护管的技术要求,进步了外护管的全体质量。
9. The polyurethane direct buried pipe is made of high density polyethylene (HDPE) material, supplemented by various additives such as antioxidants, and the original data and the quality of the product are strictly checked to ensure that the quality of the product reaches the CJ/114-2000 specification and the technical requirements of the external protective pipe of the direct buried pipe, thus improving the overall quality of the external protective pipe.
