保温铝卷由熟练工人在生产线上加工，由于各种原因，加工出来的保温铝卷可能会有一些误差，但这个误差一定要控制在一定范围内，否则就是不合格产品。这些错误一定要尽量减少，完全避免。铝卷生产厂家认为，无论是钣金加工还是喷涂工艺，都要注意精度。
Thermal insulation aluminum coils are processed by skilled workers on the production line. Due to various reasons, the processed thermal insulation aluminum coils may have some errors, but this error must be controlled within a certain range, otherwise it will be unqualified products. These mistakes must be minimized and completely avoided. Aluminum coil manufacturers believe that precision should be paid attention to both sheet metal processing and spraying process.
据铝卷内保温厂家介绍，铸造成型件并非所有表面都经过机加工，未机加工表面在铸造过程中形成过厚的氧化层，部分表面夹有砂层。此时，该部位原有的氧化膜应通过机械加工或喷砂去除，或碱洗后处理。只有这样，才能去除未加工零件的原始氧化层，避免加工零件公差尺寸的变化。
According to the introduction of the thermal insulation manufacturer in the aluminum coil, not all surfaces of the casting molded parts have been machined, and the unmachined surfaces have formed too thick oxide layers during the casting process, and some surfaces have sand layers. At this time, the original oxide film of this part shall be removed by machining or sand blasting, or treated after alkali washing. Only in this way can the original oxide layer of the unprocessed part be removed, and the change of the tolerance dimension of the machined part can be avoided.
整个保温铝卷材工程的铝单板不是直接按照图纸一次生产完全，直接交给施工方。而是在一批货物生产完成后，让建筑工人完成安装，然后进行下一批生产加工。这就要求保温铝卷材加工厂的产品误差不要太大，一个小小的初始误差就会让后续的铝单板加工面临数据问题，产品容易遇到安装的问题，这就叫“微失千里”。
The aluminum veneer of the entire thermal insulation aluminum coil project is not directly produced in one time according to the drawings, but directly delivered to the construction party. Instead, after the production of a batch of goods is completed, the construction workers will complete the installation and then proceed to the next batch of production and processing. This requires that the product error of the thermal insulation aluminum coil processing plant should not be too large. A small initial error will make the subsequent aluminum veneer processing face data problems, and the product is prone to installation problems, which is called "slight loss of thousands of miles".

保温铝卷材的加工应选择可靠的厂家，这不仅会保证产品质量，还会影响施工进度。保温铝卷材工艺应按管道保温层外圆周加30毫米搭接长度切割：搭接宽度为30毫米；在卷绕机上形成保温铝皮；在压边机上进行周向和横向压边成形；在管道的外绝缘表面；取与迎顺风向，且搭接处一致，尽量在阴凉处；
Reliable manufacturers shall be selected for the processing of thermal insulation aluminum coil, which will not only ensure the product quality, but also affect the construction progress. The process of thermal insulation aluminum coil shall be cut according to the outer circumference of the pipe insulation layer plus 30mm lap length: the lap width is 30mm; Forming thermal insulation aluminum sheet on the winding machine; Carry out circumferential and transverse blank holding forming on the blank holder; On the external insulating surface of the pipe; It shall be consistent with the wind direction, and the lap joint shall be in the shade as far as possible;
保温铝卷的保护层靠近保温层并与保温层为一体；按照规定的“三距”间距，在压边圈附近用自攻螺钉(或自攻铆钉)横向固定。使用自攻螺钉后，绝缘铝线圈表面平整无凹凸。绝缘铝卷铝皮绝缘铝卷的保护层紧贴绝缘层，搭接宽度符合规定要求；整体美观，中心在同一条线上，大小一样；周向和横向都有压边圈。
The protective layer of thermal insulation aluminum coil is close to and integrated with the thermal insulation layer; Use self tapping screws (or self tapping rivets) to fix laterally near the blank holder according to the specified "three pitch" spacing. After using the self tapping screw, the surface of the insulated aluminum coil shall be flat without unevenness. The protective layer of the insulating aluminum coil is close to the insulating layer, and the overlapping width meets the specified requirements; The overall appearance is beautiful, the center is on the same line, and the size is the same; There are blank holders in both circumferential and lateral directions.
