Generally speaking, the flow of the ventilation system is very large, so it is required to use the air pipeline with smaller resistance to save the cost and operation cost. Today, Jinan ventilation pipe processing factory will introduce the application of air duct technology in ventilation engineering.

一般情況下使用鍍鋅鐵管，有腐蝕性及特別潮濕的場所使用不銹鋼管。使用范圍：無塵室，半導體工業(yè)，印制電路板工業(yè)，石油化學工業(yè)，配藥工業(yè)，紙漿和造紙工業(yè)，食品加工工業(yè)，包括易燃、揮發(fā)性、腐蝕性化學制品的實驗室、任何關于腐蝕性、易燃排氣管運送和輸出的工業(yè)或設施。系統(tǒng)漏風量測試可以整體或分段進行。測試時，被測系統(tǒng)的所有開口均應封閉，不應漏風。

In general, galvanized iron pipe is used, and stainless steel pipe is used in corrosive and humid places. Scope of application: dust free room, semiconductor industry, printed circuit board industry, petrochemical industry, dispensing industry, pulp and paper industry, food processing industry, including laboratories for flammable, volatile and corrosive chemicals, any industry or facility for transporting and exporting corrosive and flammable exhaust pipes. The air leakage test of the system can be carried out as a whole or in sections. During the test, all openings of the tested system shall be closed without air leakage.

成品保護:安裝完的風管要保證表面光滑清潔，保溫風管外表面整潔無雜物。室外風管應有防雨、雪措施。特別要防止二次污染現(xiàn)象，必要時應采取保護措施。

Finished product protection: the surface of the installed air duct shall be smooth and clean, and the external surface of the thermal insulation air duct shall be clean and tidy without sundries. Outdoor air duct shall be provided with rain and snow proof measures. In particular, secondary pollution should be prevented and protective measures should be taken when necessary.

PIG清管：PIG工業(yè)清管技術是依靠泵推動流體產(chǎn)生的推動力驅動PIG(清管器)在管內向前推動，將堆積在管線內的污垢排出管外，從而達到清洗的目的。該技術被廣泛用于各類工藝管道、油田輸油輸汽管道等清洗工程，特別是對于長距離輸送流體的管道清洗，具有其他技術無法替代的優(yōu)勢。

Pig pigging: the pig industrial pigging technology relies on the driving force generated by the fluid driven by the pump to drive the pig (pig) forward in the pipe, so as to discharge the dirt accumulated in the pipeline out of the pipe, so as to achieve the purpose of cleaning. This technology is widely used in various process pipelines, oil and gas pipeline cleaning projects, especially for long-distance pipeline cleaning, which has advantages that other technologies can not replace.
