不同用处的91视频网站观看91视频成人网站所用资料也不同，下面由91视频网站观看91视频成人网站的人员引见一下：
The information used for different smoke exhaust pipes is also different. The following is introduced by the smoke exhaust pipe professionals:
按国度现行通风91视频成人网站有关规范:91视频网站观看91视频成人网站的资料选用钢板烟管(普通钢板)、镀锌板(白铁)烟管、91视频网站观看91视频成人网站不锈钢91视频网站观看91视频成人网站、玻璃钢91视频网站观看91视频成人网站、塑料91视频网站观看91视频成人网站、复合资料91视频网站观看91视频成人网站、彩钢夹心保温板91视频网站观看91视频成人网站、工业送排风91视频网站观看91视频成人网站。
According to the current national ventilation pipeline specifications: steel smoke pipe (common steel plate), galvanized steel (white iron) smoke pipe, stainless steel smoke pipe, FRP smoke pipe, plastic smoke pipe, composite material smoke pipe, color steel sandwich insulation board smoke pipe, industrial air supply and exhaust pipe are selected for the information of smoke pipe.
往常在给通风91视频成人网站降温时要留意哪些细节呢，下面引见了几点，能够理解一下:
What details should we pay attention to when cooling ventilation ducts in the past? Here are a few points to understand.
1、应按某系统的某楼层通风91视频成人网站停止绘制，并注明接口位置。
1. Firstly, the drawing should be stopped according to a floor ventilation pipe of a certain system, and the locations of the interface should be indicated.
2、通风91视频成人网站设计应停止编号，从起点开端编号，起点普通为接口位置，相同断面规格、相同长度节为同一号码，除此应按次第编号。以便于组织制造施工。
2. The design of ventilation pipes should stop numbering, starting from the beginning, the common starting point is the interface locations, the same section specifications, the same length section is the same number, in addition, should be numbered according to the order. In order to facilitate the organization of manufacturing and construction.
3、通风91视频成人网站设计必需标示支吊架位置，支吊架位置间距及一切资料规格必需符后标准请求及工艺规则。
3. The design of ventilation pipeline must indicate the position of support and hanger, the distance between supports and hangers, and all data and specifications must conform to the standard requirements and process rules.
4、制造通风91视频成人网站设计时应优先思索弯头与变径满足内表面面同心弯管请求、变径长度请求。
4. In the design of manufacturing ventilation ducts, priority should be given to the elbow and diameter change to meet the requirements of concentric elbow on the inner surface and diameter change length.
5、通风91视频成人网站设计应标示起端与弯头位置、变径位置、管线所处轴线位置、管底标高。
5. Ventilation pipeline design should indicate the position of the beginning and elbow, the position of the diameter change, the position of the axis of the pipeline, and the elevation of the bottom of the pipeline.
91视频网站观看91视频成人网站在系统分为：吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等在工业及建筑工在工厂及写字楼的空调系统，工业污染控制用除尘、91视频网站观看、吸油等排风管、工业环境或岗位温馨用送风管。这些91视频网站观看91视频成人网站依照用处的辨别就是这几种，在楼房排水的91视频成人网站中普通不采用91视频网站观看91视频成人网站的烟管，由于雨水很容易腐蚀钢铁，所以在排水91视频成人网站上普通选用pc管。
In the environmental protection system, smoke exhaust pipes are divided into: suction and exhaust pipes, mine gas exhaust pipes, mine coated ducts, etc. in the central air conditioning system of industrial and construction workers in factories and office buildings, industrial pollution control exhaust pipes such as dust removal, smoke exhaust, oil suction, industrial environment or post warm air supply pipes. These smoke exhaust pipes are distinguished according to their use. In building drainage pipes, smoke exhaust pipes are usually not used. Because rainwater is easy to corrode steel, PC pipes are usually used in drainage pipes.
在煤矿消费中91视频网站观看91视频成人网站也是必不可少的，在井下作业，由于远离空中，空气不容易抵达，容易积聚大量的瓦斯气体，这些气体就需求通风91视频成人网站及时的保送到空中避免爆炸，在煤矿中的通风91视频成人网站的资料普通为铁质的和塑料的。
In coal mine consumption, smoke exhaust pipeline is also indispensable. In underground operation, because it is far from the air, air is not easy to reach, and it is easy to accumulate a large number of gas. These gases need ventilation pipelines to be sent to the air in time to avoid explosion. The information of ventilation pipelines in coal mine is generally iron and plastic.
