保溫鋁卷由熟練工人在生產線上加工，由于各種原因，加工出來的保溫鋁卷可能會有一些誤差，但這個誤差一定要控制在一定范圍內，否則就是不合格產品。這些錯誤一定要盡量減少，完全避免。鋁卷生產廠家認為，無論是鈑金加工還是噴涂工藝，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.
據鋁卷內保溫廠家介紹，鑄造成型件并非所有表面都經過機加工，未機加工表面在鑄造過程中形成過厚的氧化層，部分表面夾有砂層。此時，該部位原有的氧化膜應通過機械加工或噴砂去除，或堿洗后處理。只有這樣，才能去除未加工零件的原始氧化層，避免加工零件公差尺寸的變化。
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.
整個保溫鋁卷材工程的鋁單板不是直接按照圖紙一次生產完全，直接交給施工方。而是在一批貨物生產完成后，讓建筑工人完成安裝，然后進行下一批生產加工。這就要求保溫鋁卷材加工廠的產品誤差不要太大，一個小小的初始誤差就會讓后續(xù)的鋁單板加工面臨數據問題，產品容易遇到安裝的問題，這就叫“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".

保溫鋁卷材的加工應選擇可靠的廠家，這不僅會保證產品質量，還會影響施工進度。保溫鋁卷材工藝應按管道保溫層外圓周加30毫米搭接長度切割：搭接寬度為30毫米；在卷繞機上形成保溫鋁皮；在壓邊機上進行周向和橫向壓邊成形；在管道的外絕緣表面；取與迎順風向，且搭接處一致，盡量在陰涼處；
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;
保溫鋁卷的保護層靠近保溫層并與保溫層為一體；按照規(guī)定的“三距”間距，在壓邊圈附近用自攻螺釘(或自攻鉚釘)橫向固定。使用自攻螺釘后，絕緣鋁線圈表面平整無凹凸。絕緣鋁卷鋁皮絕緣鋁卷的保護層緊貼絕緣層，搭接寬度符合規(guī)定要求；整體美觀，中心在同一條線上，大小一樣；周向和橫向都有壓邊圈。
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.
