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.
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.
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.

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