Plastic coated composite pipe is on the inner wall of the steel melts to dissolve a thickness of 0.5 ~ 1.0 mm layer of polyethylene (PE) resin, ethylene - acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC) and other organic matter and constitute a steel-plastic composite pipe material.
Advantage
Plastic coated composite steel pipe is protected by plastic coating both inside and outside. In the middle, it is used to strengthen the composite structure of welded steel pipe or seamless pressure steel pipe, which overcomes the defects of easy rust, corrosion, high pollution, low strength and deformation of plastic pipe, and integrates the common advantages of steel pipe and plastic products. it not only has steel tube high strength, easy connection, water resistance and other advantages, also overcomes the steel easy to corrosion, under the influence of water pollution, scale and strength of plastic pipe is not high, poor fire performance shortcomings, design life of 50 years.

When explosion-proof air conditioners are installed, explosion protection of the power supply is mainly used. Avoiding heat sources, hot air discharge and noise should not affect neighbors, and the external height should be slightly lower than the internal machine to facilitate the circulation of refrigeration oil. The air conditioning air intake must be covered during the renovation process, and the filter should be cleaned after the renovation. Keep it clean.
The installation of the internal and external equipment is not very strict. It is possible to leave the wall at 10-20. The upper and lower requirements are strict and the main ventilation effect must be smooth. Your home situation 1: The outdoor temperature is lower than the rated temperature of the air-conditioner (minus about 20) 2: Air-conditioner lacks fluorine or excessive fluorine after maintenance.
1. Installation location of outdoor unit 1.1 Explosion-proof split type air conditioner has large cooling capacity and the outdoor unit is heavy (usually the host of 2 horses is about 45b, the host of 3 horses is about 70kg, and the host of 5 horses is about 90kg, so it should be selected The place where it can withstand the quality and vibration of the unit, and will not produce much vibration and noise, such as the prefabricated exterior wall floating platform for building concrete.
1.2 Install as much of the shade as possible (if facing north).
1.3 Leave some space before, after, left, and right of the unit to facilitate drainage, heat dissipation, and ease of installation and maintenance. The unit should be more than 50cm in front of the obstacle, 10cm above the upper part, and more than 10cm away from the left and right sides.
1.4 Avoid the influence of flammable gas, corrosive gas, heat source and steam source (eg kitchen), and it is advisable that the air outlet of the unit does not affect the neighbors.
2. Installation position of indoor unit 2.1 Select the position where the influence of external air is the smallest and the distance to the outdoor unit is the shortest, so that the indoor and outdoor unit connection pipelines are as short as possible to reduce the flow resistance of the refrigerant.
2.2 explosion-proof split cabinet type air conditioning indoor unit larger size, usually placed directly on the ground or welded support frame, can not be close to the heat source, try to make cold (or hot) wind can be sent to all areas of the indoor air distribution.
2.3 The front of the indoor unit and left and right sides should leave a certain space: in general, there should be 100c1TI right in front and 50cm on both sides to facilitate air circulation.
3. Installation of explosion-proof air-conditioning indoor unit 1. Drill the hole through the wall. After the position of the wall hole is determined according to the direction of the site pipe, an electric impact drill is used to punch through the wall hole (about 60 mm in ping). The wall hole is slightly inclined from the inside out to facilitate the discharge of condensate, and at the same time to prevent wear of the pipe through the wall, Put a protective tube around the hole in the wall.
2. Wrap the piping with the insulation material together with the wires and drains with tape.
3. Place and tighten the indoor unit.

Explosion-proof air-conditioning installation position selection standard
Explosion-proof air conditioner has all the functions with home air conditioning, but it is a kind of explosion-proof electrical appliances, mainly used in the flammable and explosive environment of petroleum, chemical,*, oil depot, offshore oil platform, cooling and heating, appearance of explosion-proof air conditioner and Usage is the same as normal air conditioning. Explosion-proof air conditioners are divided into high temperature, low temperature, special high temperature, and special low temperature according to the working environment.
