Analysis on the performance characteristics of high-temperature resistant ventilation pipes, selection of high-temperature telescopic ventilation pipes and how to install them
One, what is a high temperature resistant vent pipe?
High temperature resistant air duct is the most common ventilation duct in modern industrial production. The surface of the high temperature resistant air duct is concave and convex, abrasion resistant, light weight, high flexibility, flexible and flexible, easy to install and use. It is widely used in various industries, such as hot gas extraction of high-temperature boilers, automobile exhaust emissions, factory solder fume extraction, blast heater exhaust and welding gas exhaust, exhaust equipment, engine structures, heating engines, solids Such as dust, powder and fiber, gas environment such as steam and smoke, dust removal and extraction plant, heater exhaust, and low-pressure environments such as aircraft equipment and military coordination bellows and compressors.
2. What are the performance characteristics of high temperature resistant ventilation pipes?
Properties: double layer, good heat resistance, retractable; the outside is protected from wear by the spiral wire, which can be dragged on the ground at will without damaging the air duct, and the external steel wire is tightly clamped on the pipe wall, which is not easy Kink, strong toughness; arbitrary expansion and contraction.
Material: Tube wall material: Internal and external stainless steel wire reinforcement and special glass fiber coating, spiral wire: stainless steel (VA)
Temperature range: about -60 °C to +600 °C, up to +700 °C in a short time. Its size is 75-1000MM, and it can be made in any length.
structure: patented CP structure, external spiral metal wire support (metal sheet + wire), double wall;
Three. How to distinguish high-quality high-temperature telescopic ventilation pipes?
1. Look at the surface: check the external and internal surfaces. The surface of a high-quality high-temperature air duct should be very smooth, free of stains, wrinkles, roughness and uneven spots.
2. Look at the pitch: the pitch of the elastic steel wire and the glass fiber thread are the same, and the winding is even.
3. Look at bending: the product bends freely and is elastic
Fourth, how to install the high temperature resistant ventilation pipe?
Many customers don’t know how to install the high temperature resistant vent pipe after buying it back, and don’t know how to choose the size. In fact, this is very simple. The outer diameter of the equipment or ventilation system interface is the inner diameter of the high temperature resistant vent pipe to be purchased. This type of duct is based on the inner diameter. For example, if the outer diameter of the interface is 250mm, then it is enough to buy a high-resistant duct with an inner diameter of 250mm. Speaking of this, many customers may have questions, and the same size can be inserted. Is it? Like Hangzhou Haikuo produces high temperature air ducts, all dimensions are converted in inches, for example, 10 inches is actually 254mm, which means that the actual size of our conventionally produced ducts with an inner diameter of 250mm is 254mm, so the outer diameter of the duct is 254mm. The diameter of 250 is just right, and then it can be locked with a stainless steel hose clamp.
