浅谈聚氨酯发泡接口保温

A brief discussion on the insulation of the interface of polyurethane foams

分别介绍了电热熔焊接头、热收缩带接头及电热熔焊+热收缩带接头三种集中供热直埋管道工程接口保温工艺的工艺流程,并对其进行说明,探讨了施工中的问题,阐述了施工质量检查内容及补伤方法,以期指导施工。

It introduces respectively the technical procedures of the insulation of the connector of central heating and plow-in pipes construction. The concerned technologies are electro fusion welding joint, the connector of heat shrinkable wraparound sleeve, and the connector of the corn- bination of dectro fusion welding and heat shrinkable wraparound sleeve. It gives illustration on those technical procedures, discusses the prob- lems during the construction, and describes the contents of the examination of construction quality and the remedial measures in the hope of providing referenee to constructions.
