Plastic pipe production method:

1. Extrusion molding of polypropylene raw material by injection molding machine
   The injection-molded PP plastic ductwork is fully automated, with uniform specifications and small errors, and can be customized in various lengths. At present, the size of the injection-molded air duct is only suitable for diameters below 600MM.

1. Bending and forming of polypropylene sheet
   For large-diameter plastic air ducts, it is necessary to use a specific PP sheet for welding and production. Plastic air ducts with a diameter greater than 500 are prone to deformation, so flanges need to be used to reinforce the PP air duct body.

How is Plastic pipe made?

1.The specifications, types, properties, and thickness of PP air duct materials should conform to the design drawings and the national industry product standards.

2.Quality requirements during production:
(1) The specifications and dimensions of the PP plastic ductwork must meet the design requirements;
(2) The appearance requirements of PP air ducts must meet the requirements of straight folding angles, uniform arcs, parallel surfaces at both ends, and no warped feet;
(3) The inner surface of the air duct should be smooth, and it is strictly forbidden to have horizontal joints and set reinforcing ribs in the duct or adopt the reinforcement method of convex ribs. Minimize longitudinal seams at the bottom. When the bottom edge of the rectangular air duct is less than 800mm, there shall be no longitudinal seam on the bottom edge. All nuts, bolts, washers and rivets should be matched with the performance of the pipe, using materials that will not produce electrochemical corrosion, or galvanized, etc.; the bite seam of the clean air duct must be tightly connected, with uniform width and no holes. Half bite and bursting phenomenon.

(4) After the air duct is made, perform a wipe test again; check the inner surface of the air duct with white silk cloth, and there must be no oil stains and floating dust, and then seal the opening with plastic film. Installation, the stacking yard of the air ducts should be flat, and the number of stacking layers should be determined according to the wall thickness of the air duct and the diameter of the air duct. cause deformation.
(5) The gasket of the air duct connection flange should be closed-cell sponge rubber, and its thickness should not be less than 5mm.

Plastic Ducting, the plates, profiles and other main finished materials used in the production and installation of air ducts, should comply with the current national standards for design and related products, and apply the factory inspection certificate. Common Plastic Ducting is PVC material and PP material. Because of its good corrosion resistance, it can be used in various environments.

The shape classification generally includes: circle, rectangle, spiral, etc.;

Application of plastic duct

Plastic Ducting is mainly used in industrial and construction engineering. The application fields mainly involve: electronic industry dust-free workshop purification system, pharmaceutical and food aseptic workshop purification system, central air-conditioning system of hotels, shopping malls, hospitals, factories and office buildings, industrial pollution control. Exhaust pipes for dust removal, smoke exhaust, oil absorption, etc., air supply pipes for industrial environment or post comfort, gas extraction and drainage systems for coal mines, and return air systems for coal mine environment control, etc.;

plastic duct Construction

1. For more complex civil buildings, in the design stage, various types of work (heating, ventilation, water supply and drainage, power supply and lighting, and architectural majors) should first negotiate the space separation, and determine the elevation range of each pipeline. In general, you should not go beyond the limits set by yourself. Consult with other projects when individual pipe sections are out of bounds.
2. The principle of solving the collision and coordination of various ventilation pipes is generally: “Small pipes let big pipes, and there is pressure and no pressure”. For example, if a water pipe collides with an air pipe, the water pipe should bend. If the cold and hot water pipes collide with the sewer pipes, the cold and hot water pipes should be changed.
3. Before construction, the engineer in charge of the equipment should draw the pipelines and single lines of various types of work on a floor plan. Use one colored pen for each type of pipe. Synthesize the elevations at each intersection to see if there are any contradictions, find them in time, and solve the problem before installation.
4. In order to reduce investment, save space, and reduce floor height, some pipes without slope requirements can be laid through beams (such as water pipes, fire sprinkler pipes, etc.).

Features of plastic duct:

PP plastic pipes
1. No rust: PP pipe can withstand the corrosion of PH value in a wide temperature range and high concentration of acid and alkali ranging from 1 to 14.
2. Wear resistance and no scaling: The inner wall of the PP pipe and its fittings is uniform and smooth, with low flow resistance and no scaling.
3. Reduce vibration and noise: PP pipe has very good sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.
4. Anti-freeze cracking: PP material has excellent elasticity, so that the section of the pipe and pipe fittings can expand together with the frost heaving liquid without bursting. 5. Anti-condensation, less heat loss: PP material is a poor thermal conductor, which can reduce condensation and reduce heat loss.
5. Simple installation: PP pipe is light in weight, easy to install and operate, and has weldability.
