The materials of plates, profiles and other primary products used in the manufacturing of air ducts and equipment, and the planning and manufacturing of ventilation ducts should conform to the rules of the planning and the current specifications of the relevant products, and the factory inspection certificate should be used. The materials should be inspected according to the current relevant specifications when leaving the site.

在通風管道設備的時分要關于風管的方位，高度，走向都要進行規劃好，在風管的直徑上面要求能夠確保關于空氣的更新的速度。

The orientation, height and direction of the air duct should be well planned during the time of ventilation duct equipment. The diameter of the air duct should ensure the speed of air renewal.

關于風管的聯接部分，要進行緊密聯接，所選用的墊片的厚度應該不小于3mm,墊片不該凸入管內,亦不宜杰出法蘭外。關于金屬性的風管在轉彎的時分要遵照嚴厲的設備要求。關于塑料軟管在彎道時要留神不該該有死彎或許塌陷。

The connection part of the air duct shall be tightly connected. The thickness of the gasket selected in the center shall not be less than 3mm. The gasket shall not protrude into the pipe or outside the outstanding flange. The metal air duct shall comply with strict equipment requirements when turning. Be careful not to have a dead bend or collapse when the plastic hose bends.

風管設備前,應內、外雜物,并做好清潔和保護作業。一同關于風管的聯接部分的螺絲的方位要盡或許的便當往后的修理。

Before the air duct equipment, the sundries inside and outside shall be cleaned and protected. The orientation of the screws on the connecting part of the air duct should be as convenient as possible for future repair.

通風管道作業時，會將外界新鮮空氣順暢帶入室內。如在日常日子中或自界說場景發生的條件下,人們通過通風管道然后確保一些有煙霧或環境中一氧化碳通過空氣流轉得到稀,然后不讓人們被有害氣體煩擾。

When the ventilation duct works, it will smoothly bring the outside fresh air into the room. For example, in daily life or under the conditions of self-defined scenes, people pass through the ventilation ducts and then ensure that some smoke or carbon monoxide in the environment is diluted through air circulation, and then do not let people be disturbed by harmful gases.

通風管道的聯接辦法有靈敏和多樣化,因為它的環繞玻璃鋼管道接頭辦法呈現不同的特色,使它在詳細的施工條件的根底上,能夠更大程度上增加管道聯接的靈敏性,然后前進項目自身的牢靠性。

The connection method of the ventilation pipe is sensitive and diversified, because its connection method around the GRP pipe presents different characteristics, which enables it to increase the sensitivity of the pipe connection to a greater extent on the basis of the detailed construction conditions, and then advance the reliability of the project itself.
