PP polypropylene ventilation pipe

Product Introduction

PP polypropylene ventilation pipe is a piping system used for air transportation and distribution. The PP duct is a ventilation duct made of PP material. Compared with air ducts of other materials, it has the characteristics of wear resistance, non-scaling, low flow resistance, corrosion resistance, etc., and has the characteristics of anti-freeze cracking and sound insulation. It is a widely used pipe at present. Due to these characteristics of the PP air duct, it is also used in waste gas environmental protection equipment to reduce the concentration of harmful gases and allow air to circulate.

Product Connection

Both ends of each pipe section are rolled into drum rods connected by bands, and one end is shrunk into a small opening. When installing, insert the small port into the large port according to the airflow direction. On the outside, fasten the drum rods at the two tube ends and connect them with bolts, and the bolts are fixed and fastened to the earrings.

Product Installation

1. The distance between the boom and the end of the cross arm is 30mm; the distance between the boom and the outside of the windpipe (the outer edge of the insulation layer) is 30mm.

2. When the length of the PP duct exceeds 20m, no less than one fixed bracket should be added. When the length of the PP duct exceeds 20m, an expansion joint should be added according to the design requirements.

3. The orientation of the channel steelhead and angle steel of the support and hanger should only have two orientations (horizontal and longitudinal) in the same area. In addition, the spacing between the duct supports and hangers should be uniform and even, and supports and hangers should be added at both ends of the elbow.

4. Insulation wooden support should be added between the air-conditioning duct hoisting pipe and the support and hanger.

5. The position of the PP duct support and hanger should be accurate and the direction should be the same. The boom should be vertical and there should be no distortion. The suspended duct and parts should be set with fixed points for placing and swinging.

6. The paint on the boom should be even and the color should be the same. After the air duct is installed, repaint the anti-rust paint.

7. During installation, leave 5cm outside of the boom; after installation, heat preservation, suppression, and other work are completed, after passing the inspection, cut the boom, and leave 2–3 buckles outside the nut.

8. The distance between the main duct hanger and the branch pipe should not be less than 200mm.
