- Long service life: Under the condition of rated temperature and pressure, PP air duct can be safely used for more than 50 years.
- Outstanding corrosion resistance: PP air duct can resist the corrosion of most chemicals, and can withstand the corrosion of high concentration acids and alkalis in the PH value range of 1-14 in a wide range.
- High stiffness: because of the addition of glass fiber reinforcement material, the PP air duct is not easy to deform.
- The heat-resistant, thermal insulation and energy-saving PP air duct has a high operating temperature of 95 degrees, and the thermal conductivity of the PP air duct is only 1/200 of the steel pipe, so it has a good thermal insulation function.
- Reliable connection function: The strength of the hot melt interface of the PP air duct is higher than that of the pipe body, and the joint will not be broken due to soil movement or load.
- PP air duct is light in weight, simple in welding process, and easy in device maintenance.
- In order to make full use of the water pressure in the outdoor PP air pipe network, the water supply inlet pipe is declared to be located in a place with a large water consumption or a place where continuous water supply is not allowed.
- PP air duct is another excellent resin type developed after nylon, it is a linear polymer with high density, no side chain and high crystallinity, and PP air duct has excellent comprehensive functions. white translucent, waxy when uncolored; Lighter than polyethylene. The transparency is also better than that of polyethylene, and it is harder than polyethylene.
- PP air duct is suitable for corrosive gas pumping, discharge pipeline, specific industries are electroplating industry, chemical industry, electronics industry, and can make pipe fittings, such as 90 elbows, tees, 45 elbows and 180 degree moon bends and oblique three-way for water treatment industry air ducts can be round and square according to customer requirements.
Five characteristics of PP air duct
1.Superior acoustic and thermal insulation
- PP air duct has excellent performance with low thermal conductivity. There are countless independent bubbles that are not connected to each other in the material, and the thermal conductivity of the gas in the bubble is low, so as to achieve excellent thermal insulation effect, and at the same time, this closed bubble structure makes the water vapor can not enter the material smoothly, even if the outer surface is damaged, because the bubbles are not connected with each other, the water vapor is still isolated. In non-closed-foam materials, water vapor can penetrate deep into the material, causing insulation failure.
2.Chemical stability
- Polymer is an inorganic material, which cannot be achieved by general foaming materials in case of acidic and alkaline substances.
3.High flame retardancy
- Because it is mainly an inorganic component, when it encounters fire, only the surface is carbonized, and the material is not deformed, and all the indicators of PP air duct are in line with national standards.
4.Non-toxic
- The polymer has been tested and has no harm to the human body, which is incomparable to glass fiber.
5.High airtightness
- According to the requirements, the air leakage volume can be zero.
Precautions for installation and transportation
- PP air ducts shall not be arranged on top of water that can cause combustion, blasting or damage to raw materials, products and equipment, and should be avoided as far as possible on the production equipment.
- PP air ducts shall not pass through the windows of shops, closets of civil buildings and wooden decorations. For workshops and buildings that are not allowed to cut off water, two introduction pipes should be set up, and the two-way water supply should be connected in a ring or through the branch indoors.
