Fireproof Flexible Ventilation Duct
1.Structure of Fireproof Flexible Ventilation Duct：
Flexible air ducts are typically made of flexible plastic over a metal wire coil to shape a tube. And they have a variety of configurations. Flexible ducts are very convenient for attaching air outlets to the rigid ductwork. It is commonly attached with long zip ties or metal band claps. Besides, flexible ducts can tolerate moderate negative pressures.
2.Main Features of Fireproof Flexible Ventilation Duct：
-Applied in air conditioning/ventilation systems
-Tear and puncture resistant
-Corrosion resistant
-High flexibility
-Convenient installation
-No toxic gas emission

We have organized several common questions for our clients，may help you sincerely：
1.How long for the delivery time?
Delivery time: 10-30 days, it depends on the ordered quantity.
2.What’s the usage？
Practicality: suitable for the densely-populated area(such as school, supermarket, office, stadium, theater, factory.),high requirement of the environment area, such as hospital, laboratory, howff, bus, train, broadcasting studio. main usage: 1) Cold, hot water supply facilities for public buildings 2) Food, chemical, electronic industrial pipeline networks such as pipeline networks for transporting all kinds of corrosive liquid 3) Drinking water production system pipeline networks such as pure water and mineral water 4) Air conditioning facility pipeline 5) Compressed gas pipeline networks for industry 6) Pipeline network for swimming pool 7) Pipeline network for solar energy facility 8) Agriculture and garden production Additional information
③How you control the quality?
During the production of fiberglass insulation, material is sampled at a number of locations in the process to maintain quality.
- Q: Such as the problem, and now air-conditioning technology is mature, the market a lot of air conditioning are cold and warm, and I would like to be able to put my home that the end of the century loaded Mitsubishi air conditioning (split single cold) into a cold Before the conversion of ordinary TV to the remote control, that air conditioning can be modified? How much does it cost? Where is this technology? More
- So good, then you recommend more. Give an address. You are not layman, too modest.
- Q: If I feel the room cool off, one hour hot and open an hour this will be more expensive? More
- Common scaffold brace is the U-type care, "construction of fasteners steel scaffolding safety technical regulations" (JGJ Gong Gong Duo Ji-tao pan Revenge two 130-2011) provides "adjustable support bearing capacity design value is not Should be less than 40kN, the support plate thickness should not be less than 5mm ", the general calculation using 30kN.
- Q: Air to water heater host and air conditioning host is not the same
- This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.
- Q: Gree air conditioning 50 heating and cooling mechanism heat when the host cooling network is how the matter
- Not the ,,, mobile air conditioning inside the compressor, the winter heating also need the compressor, but also a ventilation pipe, charged heating Well?
- Q: Do 3cm thick wall insulation how much kilogram of slurry and how many kilograms of polystyrene particles
- From the outside: ① rigid waterproof casing is only composed of steel casing and wing ring, simple structure; ② flexible waterproof casing mainly by: flange casing, seals, flange pressure plate, wing ring, bolts, nuts Composition, complex structure From the waterproof performance up to choose: ① rigid waterproof casing is outside the wing (ring made of steel ring on the steel pipe), installed in the wall (mostly concrete wall), for the general pipe wall, ; ② flexible waterproof casing in addition to the external wing ring, the internal file ring and the like, the flange wire, there are sets of sales, but also their own processing, for the need for shock absorption pipeline, such as and pump connected When the pipe is through the wall In other words, if the wall on both sides of the waterproof performance, it is necessary to use flexible waterproof casing; if only to consider the pipe through the wall, without considering the wall, the wall on both sides of the waterproof performance and displacement of the pipeline deformation You can use rigid waterproof casing
- Q: I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More
- Common points are all sandwich panels, with a hard protective layer, the difference is the middle of the different materials, such as polystyrene board, polyurethane board. Polystyrene board which is the most common, because the price is cheap, easy to use so the use of more, but if the temperature is more than the requirements of the chicken inertia glycosylation moxibustion slim faint words, polystyrene board is not satisfied , So there is a polyurethane sandwich panels, polyurethane thermal conductivity of less than 0.. in the existing insulation materials, large quantities of processing, be the best. But because of its process is more complex, and the cost is relatively high, so with less, the common combination of cold storage and the like, I believe that with the economic and technological development, polyurethane sandwich board market share will be more and more High
- Q: What is the whole heat exchange fresh air ventilator?
- Depends on the main control panel is not cold and warm, single cold common motherboard. Only a generic motherboard can be changed. In the single cold air-conditioning on the outdoor machine to install the appropriate specifications of the four-way valve, adjust the amount of refrigerant to the appropriate level can be.
- Q: External wall insulation method of operation There are several combinations of materials
- 30-150 per square meter has, mainly to see the material, thickness and so on
- Q: The installation method of ordinary air conditioner. The more detailed the better. Please thank you all
- 2.1.23 step distance liftheight the distance between the upper and lower horizontal axis of the axis of each other. 2.1.24 pole vertical (cross) distance longitudinal spacingofuprighttube Scaffolding vertical distance between adjacent rods. 2.1.25 Vertical distance transversespacingofuprighttube Scaffolding Horizontal distance between adjacent vertical rods, single row scaffolding for the outside pole axis to the wall distance.
- Q: HVAC Heating: What are the main components of the air distribution system?
- Geothermal construction, the heating pipe spacing can not be less than 100mm, the construction can not be achieved, big brother!
