直接掩埋的热绝缘管的应用

Polyurethane directly buried thermal insulation pipe is suitable for the thermal insulation engineering of various media in the range of-50℃- -150℃. It is widely used in urban central heating, heating room, cold storage, coal mine, oil pipeline port, chemical industry, natural gas pipeline, power directly buried, central air conditioning pipeline insulation, cable pipe, steam insulation pipe and other industries热绝缘和冷保护工程{.
聚氨酯直接掩埋的热绝缘管的优势
1.根据相关部门的计算，降低项目成本.，在正常情况下，双控制加热管道可以降低25％的项目成本，将FRP用作保护层.
2.低热量损失和能源节省.其热导率为：λ= 0.013 - 0.03kcal/
MHOC比过去的其他常用管道绝缘材料要低得多，而且绝缘效应的{.}高4〜9倍，此外，其吸收率非常低，约为0 . 2 kg/m 2.，低水量的原因是92％的cosse fo aim colleture voam at po and to po and to po and to po and to po polurothane foo {低热导率和低吸水，再加上绝缘层以及高密度聚乙烯或FRP保护壳的良好防水性能，改变了传统的沟槽加热管道“穿湿垫夹克”的情况，极大地降低了加热管道的整体热量损失，热量网络损失是2％，比国际标准需求少于10％的国际标准需求。
3.抗腐蚀性，良好的绝缘性能和较长的使用寿命.，因为聚氨酯硬质泡沫绝缘层紧密粘合到钢管的皮肤上，与空气和水的浸润中分离出来，它可以在良好的抗腐蚀效应中及时{4}的水平{4 very small. High density polyethylene shell, glass RP shell have good corrosion, insulation and mechanical properties. Therefore, the outer skin of the working steel pipe is difficult to be eroded by the external air and water. As long as the internal water quality of the pipeline is well tr​​eated, according to foreign data, the service life can reach more than 50 years, which is 3~4 times higher than the传统的沟槽铺设和顶部铺设{.
{4.更少的土地面积，快速建设，有利于环境保护{.直接埋藏的加热管道不需要建造巨大的沟槽，只是将绝缘管埋在地下，从而大大降低了项目区域，从而减少了土方工程的时间，从而减少了超过50％的公民，并减少了90％的公民{40％{40％{绝缘管道处理和现场沟渠平行，只有现场关节，可以将施工时间缩短超过50％.
