Whether it is a high temperature exhaust duct or a high temperature suction duct, it is a type of high temperature duct. Many people don’t understand the difference between exhaust ducts and exhaust ducts. As a professional air duct manufacturer, today, we will focus on the differences between high-temperature exhaust ducts and high-temperature exhaust ducts and their uses:
First, high temperature exhaust duct
The high temperature exhaust pipe is the name of the tube that can withstand high temperature exhaust. The main point here is the “row”, which is the biggest difference between the two high temperature resistant ducts. It refers to the outward discharge of air volume, and the general exhaust It is a positive pressure, and many conventional pipes are only suitable for exhausting, such as ordinary aluminum foil ventilation pipe, nylon cloth air pipe, PVC telescopic ventilation hose, and the like. If you need to withstand negative pressure, you must use a high temperature exhaust pipe.
Second, high temperature suction duct
High-temperature exhaust pipe refers to a pipe that can withstand high temperature and is used for ventilation. The key point is “pumping”, which means that the fan is connected to the air duct to draw air outside. The exhaust pipe refers to the pipe that is resistant to negative pressure, and the exhaust pipe is also It can be called negative pressure air duct. The pressure is relatively large when pumping out. The pressure of ordinary high temperature exhaust pipe will not be reached. At this time, some negative pressure air ducts dedicated to ventilation can be customized. The most common resistance is Negative pressure duct, external spiral wire support (metal piece + wire), double pipe wall; pipe wall material: internal and external stainless steel wire reinforcement and special glass fiber coating.
The above describes the different points of the two types of ventilation pipes. Then, under what circumstances do you choose to exhaust the air and under what circumstances do you choose the exhaust pipe?
Mainly according to the use and equipment to choose, for example, in factories, workshops, etc., use a fan to connect the ventilation hose to discharge dust or toxic air to the outside when selecting the high temperature exhaust duct, and like the tunnel, mine and the like to connect the large duct To exhaust the wind, high-temperature suction pipe must be used. The high-temperature exhaust pipe can be directly selected by some conventional air ducts, and the high-temperature suction pipe must be customized, usually on the basis of ordinary exhaust pipes.Thickened steel wire, thickened air duct cloth, and encrypted steel ring spacing to improve the pressure resistance of the air duct.
