聚氨酯保温钢管厂家引见其在施工的时分需求留意什么
Polyurethane Insulating Steel Pipe Manufacturer Introduces What Does It Need to Pay Attention to During Construction
1.在施工进程中,不只要保证沟槽平整,还要保证槽底枯燥,且需求作200mm左右厚的细砂垫层。其目的一是避免硬物损坏保温外套管,二是应用砂子的活动性,充沛填充管道四周的空隙,以保证足够的摩擦力。
1. In the construction process, not only to ensure the smooth groove, but also to ensure that the bottom of the groove is dry, and the need for 200 mm thick fine sand cushion. The purpose is to avoid the damage of hard material to the insulating outer sleeve. The second is to fill the gap around the pipeline with the activity of sand to ensure sufficient friction.
2.聚氨酯保温管装置终了需停止1.5倍任务压力的水压实验,待水压实验合格前方可停止接口发泡处置。
2. At the end of the polyurethane insulating pipe device, the water pressure test of 1.5 times the task pressure should be stopped, and the foaming treatment of the interface can be stopped before the water pressure test is qualified.
3.一次性补偿直埋管线一定要按设计要求,预热至设计温度时要保证温度的恒定。
3. The one-time compensation buried pipeline must meet the design requirements and keep the temperature constant when preheating to the design temperature.
4.聚氨酯保温管进入修建物、地沟时应加穿墙套管,在出土端设置固定支墩。
4. When polyurethane insulating pipe enters buildings and ditches, it should be pierced with wall casing and fixed piers at the end of excavation.
5.回填土要分层夯实。回填土的质量关于管线的平安运转十分重要,一定要给予注重。
5. Backfill should be compacted by layers. The quality of backfill soil is very important for the safe operation of pipelines and must be paid attention to.

聚氨酯保温管品种划分方式有很多,例如它不只可以依照敷设方式、外护层以及保送介质等特征停止划分,还可以按照保送介质的温度停止分类。其中依照聚氨酯保温管的敷设方式,我们可将其分爲:直埋聚氨酯保温管、架空聚氨酯保温管两种。但若依照聚氨酯保温管的外护层停止划分,我们则可以将其分爲四大类,它们顺次爲:高密度聚乙烯外护层聚氨酯保温管、玻璃钢外护层聚氨酯保温管、钢外护层聚氨酯保温管以及其他外护层保温管。而若按照聚氨酯保温管保送介质停止分类的话,则可以分爲:保送蒸汽用的蒸汽直埋聚氨酯复合预制保温管、供水公用的耐低温聚氨酯保温管,与聚氨酯预制保温管以及石油行业中,常用的埋地硬质聚氨酯泡沫塑料防腐保温管。至于依照保送介质的温度,则可以分爲:低温聚氨酯保温管、常温聚氨酯保温管与深冷聚氨酯保温管三种。
There are many ways to classify the varieties of polyurethane insulating pipes. For example, it can not only be classified according to the laying method, the outer protective layer and the characteristics of the delivery medium, but also according to the temperature of the delivery medium. According to the laying method of polyurethane insulating pipe, we can divide it into two kinds: directly buried polyurethane insulating pipe and overhead polyurethane insulating pipe. However, if the outer protective layer of polyurethane insulating pipe is stopped, we can divide it into four categories: polyurethane insulating pipe with high density polyethylene outer protective layer, polyurethane insulating pipe with FRP outer protective layer, polyurethane insulating pipe with steel outer protective layer and other insulating pipes with outer protective layer. If we stop classifying according to the delivery medium of polyurethane insulation pipe, we can divide it into: steam directly buried polyurethane composite insulation pipe for steam delivery, low temperature resistant polyurethane insulation pipe for water supply, and buried rigid polyurethane foam plastic anticorrosive insulation pipe commonly used in polyurethane prefabricated insulation pipe and petroleum industry. According to the temperature of the delivery medium, it can be divided into three types: low temperature polyurethane insulating pipe, room temperature polyurethane insulating pipe and cryogenic polyurethane insulating pipe.
