圓形風(fēng)管系統(tǒng)的安裝時(shí)間只有相類(lèi)似的矩形管道的1/3。解決各種消防排煙風(fēng)管相碰及協(xié)調(diào)的原則，一般為：“小管讓大管，有壓讓無(wú)壓”。例如，自來(lái)水管與風(fēng)管相撞，則應(yīng)當(dāng)自來(lái)水管拐彎。冷、熱水管與下水管相碰，則應(yīng)改變冷、熱水管道。

The installation time of a circular duct system is only one-third of that of a similar rectangular duct. The principle for solving the collision and coordination of various fire smoke exhaust ducts is generally: "Small pipes give way to large pipes, and pressure gives way to no pressure.". For example, if the water pipe collides with the air pipe, the water pipe should be turned. If the cold and hot water pipes collide with the drainage pipe, the cold and hot water pipes should be changed.

隨著工業(yè)的發(fā)展和生產(chǎn)的擴(kuò)大，通風(fēng)管道系統(tǒng)已經(jīng)成為大型工廠、、車(chē)間、醫(yī)院、辦公樓等場(chǎng)所不可缺少的一部分。通風(fēng)管道的作用就是疏通空氣，從而降低空間中有害物質(zhì)的濃度并加快空間中的空氣循環(huán)。使用自然通風(fēng)排放有害物質(zhì)，先局部排氣，當(dāng)建筑物不滿足通風(fēng)條件時(shí)，通風(fēng)管道會(huì)在采用全方面排氣。主要用于鋼板環(huán)形風(fēng)管和螺旋形風(fēng)管的連接。在每一管段的兩端卷起鼓形加強(qiáng)件，并將其一端縮成一個(gè)小孔。在安裝過(guò)程中，根據(jù)空氣流動(dòng)的方向插入大口處。兩頭的鼓箍與鋼箍緊密相連，并由中間的螺栓固定緊固。

With the development of industry and the expansion of production, ventilation duct systems have become an indispensable part of large factories, shopping malls, workshops, hospitals, office buildings and other places. The function of ventilation ducts is to clear the air, thereby reducing the concentration of harmful substances in the space and accelerating air circulation in the space. When using natural ventilation to discharge harmful substances, local exhaust should be used first. When the building does not meet the ventilation conditions, the ventilation duct will adopt comprehensive exhaust. Mainly used for connecting steel plate circular air ducts and spiral air ducts. Roll up the drum shaped reinforcement at both ends of each pipe section and shrink one end into a small hole. During installation, insert into the large opening according to the direction of air flow. The drum hoops at both ends are tightly connected to the steel hoops and secured by the middle bolts.

進(jìn)口不銹鋼通風(fēng)管的模具選用的是特殊鋼結(jié)構(gòu)，即使在使用三五年后，受限模具的外形仍保持原樣，這樣就不會(huì)損壞鍍鋅鋼板的外觀，而且外觀也大大延長(zhǎng)。風(fēng)管使用壽命均勻平整，咬合緊密，連接力強(qiáng)，密封性能好。閥防泄漏系統(tǒng)。精巧的螺旋式限羅紋工藝，使不銹鋼管道具有良好的承壓強(qiáng)度。在加肋骨后，咬合的厚度是管徑的四倍。管線的剛度很大，顯示了加固的優(yōu)越性。能在不損壞的情況下承受加大壓力負(fù)荷，減少材料厚度15%，從而降低成本。

The mold for imported stainless steel ventilation pipes uses a special steel structure. Even after three to five years of use, the shape of the restricted mold remains unchanged, so as not to damage the appearance of the galvanized steel plate, and the appearance is greatly extended. The service life of the air duct is uniform and flat, with tight bite, strong connection force, and good sealing performance. Safety valve leakage prevention system. The exquisite spiral ribbed process ensures that stainless steel pipes have good compressive strength. After adding ribs, the thickness of the bite is four times the diameter of the tube. The high stiffness of the pipeline demonstrates the superiority of reinforcement. Can withstand increased pressure loads without damage, reduce material thickness by 15%, and thus reduce costs.

同一設(shè)備空間內(nèi)直徑200毫米的圓形管道可替代250×150毫米的矩形管，而不增加任何壓降。在不增加設(shè)備空間的情況下，多個(gè)平行的圓形管道可以取代平面的矩形管道。綜合各種因素，在大多數(shù)情況下，圓管比矩形管所占空間要小。

A circular pipe with a diameter of 200mm in the same equipment space can replace a rectangular pipe with a diameter of 250x150mm without increasing any pressure drop. Multiple parallel circular pipes can replace flat rectangular pipes without increasing device space. Taking into account various factors, in most cases, circular pipes occupy less space than rectangular pipes.
