The information used for different smoke exhaust pipes is also different. The following is introduced by the smoke exhaust pipe professionals:
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.
What details should we pay attention to when cooling ventilation ducts in the past? Here are a few points to understand.
1. Firstly, the drawing should be stopped according to a floor ventilation pipe of a certain system, and the location of the interface should be indicated.
2. The design of ventilation pipes should stop numbering, starting from the beginning, the common starting point is the interface location, 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. 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. 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. 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.
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.
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.
