First: Whether it is a real consumer enterprise of heat preservation pipes, once you look at the suspension license, it will indicate whether it is a consumer enterprise or a trade enterprise. If the name of the enterprise on the suspension license is a certain store, sales company, etc., it is definitely not a consumer manufacturer. Secondly, through telephone consultation to understand their knowledge and professional level, it is the manufacturer who can well understand the process of product consumption and manufacturing, and it seems that most of them do not understand or even pretend to understand.

二：与甲方的详细单位技术担任人交流施工的细节，先将施工所用到的设计工艺及客户的请求肯定好，还有要着重留意的是直埋式聚氨酯保温管的密度是几，普通规范保温管的密度是60立方，还有就是保温层的厚度是几，普通保温层的厚度是20-100毫米(这一点需我们依据详细的需求做出相应的选择)以及外套管的直径大小以及厚度的参数值，外套管的厚度越厚所接受的压力也就越大，是不会随便呈现裂痕变形等等问题的，思索保温管运用的温度范围，普通的保温管能确保接受的温度在170摄氏度以下。

2. Exchange the details of construction with the technical personnel of Party A. Firstly, affirm the design technology used in the construction and customer's request, and pay attention to the density of the direct-buried polyurethane insulating pipe, the density of the ordinary standard insulating pipe is 60 cubic meters, and the thickness of the insulating layer is a few, ordinary insulation. The thickness of the thermosphere is 20-100 mm (which requires us to make the appropriate choice according to the detailed requirements) and the diameter and thickness of the outer casing parameters, the thicker the thickness of the outer casing, the greater the pressure will be accepted, and there will be no crack deformation and so on. Consider the temperature range of the insulation pipe application, general. The through insulating pipe ensures that the temperature is below 170 degrees Celsius.

三：理解消费线能否采用了全自动化消费设备，产品消费触及到整个消费线的温度控制，计量精度，工艺参数等，好的消费工艺及技术配方决议了产品的质量，决议能否契合国度规范以及美国ASTM规范。

Third: Understanding whether the consumption line can adopt fully automated consumption equipment, product consumption touches the temperature control of the entire consumption line, measurement accuracy, process parameters, etc. Good consumption technology and technical formula determine the quality of the product, whether the decision conforms to national standards and American ASTM standards.

四：能否有良好的售后效劳，聚氨酯保温管购置以后，如何装置、如何维护才是关键，所以假如购置的聚氨酯保温管没有完善的售后效劳，则会给消费者带来很多费事。

Fourth: Whether there is good after-sales service, after the purchase of polyurethane insulation pipe, how to install and maintain is the key, so if the purchase of polyurethane insulation pipe does not have perfect after-sales service, it will bring a lot of trouble to consumers.

五：理解对方的业绩状况，就是协作同伴，能够给我们一定的参考，判别厂家的实力状况。

Fifth: Understanding each other's performance is to cooperate with peers, which can give us some reference and judge the strength of manufacturers.

六：充沛的思索和检验保温管的质量，普通保温管的运用年限在30-50年之间，确保所购产品的运用寿命。

Sixth: Plenty of thinking and inspection of the quality of insulating pipes. The service life of ordinary insulating pipes is between 30 and 50 years to ensure the service life of the products purchased.

七：充沛思索到直埋保温管厂家的一个综合实力，厂家的实力能否直接或间接决议了其能否有的保温管加工技术及良好的产质量量和施工质量，总的就是作为商家在购置前且要多问多听多调查，综合的停止比拟才干选出理想的保温管产品。

Seventh: Consider abundantly to a comprehensive strength of the directly buried heat preservation pipe manufacturer. Whether the strength of the manufacturer is strong directly or indirectly decides whether it has advanced heat preservation pipe processing technology and good quality of production and construction. Generally speaking, as a merchant, it is necessary to ask, listen and investigate more before purchasing, and stop comparing talents comprehensively. Ideal insulation pipe products.

八：直接亲身去工厂调查，包括消费设备、办公场所、消费车间、仓库等，眼见为实践，本人实践的看看，对厂家取得愈加直接的理解。

Eighth: Go directly to the factory to investigate, including consumer equipment, office space, consumer workshop, warehouse and so on. Seeing is practice, I have a more direct understanding of the manufacturer.
