Ventilation duct construction technology has its own set of construction standards, and ventilation duct manufacturers strictly implement such standards. Let's take a look at how Jinan ventilation pipe processing factory does a good job in ventilation pipe insulation!

1、安裝時應先大管后小管，先彎頭，三通后直管，閥門；絕熱層縱橫向的接縫，應錯開；保溫膠水宜均勻的涂在管道、部件或設備外表面上，絕熱材料與管道、部件及設備表面應緊密貼合，無空隙。

1. During installation, large pipe shall be followed by small pipe, elbow shall be followed, tee shall be followed by straight pipe and valve; The vertical and horizontal joints of the insulation layer shall be staggered; The thermal insulation glue should be evenly applied on the outer surface of pipes, components or equipment. The thermal insulation material should closely fit the surface of pipes, components and equipment without gap.

2、管道保溫前，要求先清理干凈管道表面污染物，后進行保溫材料的施工，避免膠水粘接力不夠，保溫材料粘結開裂；確認管套規格是否保溫管相符，避免出現偏大或偏小現象。

2. Before pipeline insulation, it is required to clean the pollutants on the pipeline surface before the construction of insulation materials to avoid insufficient glue adhesion and cracking of insulation materials; Confirm whether the specification of the pipe sleeve is consistent with the insulation pipe to avoid large or small phenomenon.

3、空調工程的制冷系統管道，包括制冷設備和空調水系統絕熱工程的施工，應在管路系統強度與嚴密性檢驗合格和防腐處理結束后進行。

3. The construction of refrigeration system pipelines of air conditioning works, including refrigeration equipment and air conditioning water system insulation works, shall be carried out after the pipeline system strength and tightness inspection are qualified and the anti-corrosion treatment is completed.

4、安裝后所有的三通、彎頭、閥門、法蘭和其他附件都需要達到設計厚度；所有單層保溫管套都要加貼封條，確保密封；所有的接縫都盡量安裝在不顯眼處，以保證美觀；所有接口和支撐的地方都要用專用膠水粘接，以保證密封，防止跑冷，出現結露現象。

4. After installation, all tees, elbows, valves, flanges and other accessories shall reach the design thickness; All single-layer insulation pipe sleeves shall be pasted with seals to ensure sealing; All joints shall be installed in inconspicuous places as far as possible to ensure beauty; All interfaces and supports shall be bonded with special glue to ensure sealing and prevent cold running and condensation.
