// Introduction //

PVC-U irrigation pipes are made by polyvinyl chloride (PVC) resins and the additives necessary for the manufacture and performance requirements of the Standard.

BaosuTM PVC-U irrigation pipes meet GB/T 13664-2006 Unplasticized polyvinyl chloride (PVC-U) pipes for low-pressure conveyance in irrigation.

// Characteristics //


1. Weight light, load and transport portable

PVC-U pipe proportion is only steel pipe and iron pipe 1/5, concrete pipe 1/3. Pipe weight is about the same specification and length ductile iron pipe 1/4, concrete pipe 1/10. Therefore, PVC-U pipe is load and transport portable and can reduce transport cost.1/2-1/3.

2. Resistant acid, no rusty, no corrode treatment.

3. Smaller flowing resistance

PVC-U pipe inside wall is smooth and smaller flowing resistance, manning coefficient is 0.008-0.009, CONVEY water is more than iron pipe 20%, and more than concrete pipe 40%.

4. Service life

Traditional pipe service life is 20-30years. PVC-U pipe service life is at least 50yearsat a set temperature and pressure.

5. Jointing convenient and installing simple

PVC-U pipe weight light and convenient, has some ductile. For installing ,comparable with other pipes, pipe system is more complex PVC-U pipe virtues is more prominent.

6. Repair easily

PVC-U pipe repairing cost is only ductile pipe or concrete pipe 30%.

// Application fields //

Baosu™ PVC-U irrigation pipes are widely applied in sprinkler irrigation, micro irrigation, low pressure conveyance.

// Application fields //


Baosu™ PVC-U irrigation pipes installing methods: T-S jointing and R-R elastic rubber sealing ring jointing.

T-S jointing steps

1.Cutting—pipe should meet requirements about dimensions, perpendicular cutting,bevel.
2.Cleaning-outside spigot and inside socket dust and oils should be cleaned.
3.Brushing- outside spigot and inside socket should be brushed quickly uniform cementing medium.
4.Inserting-then quickly finding the center lines of the socket and spigot, inserting and spinning1/4 circle for cementing medium uniform spigot and socket seam.
5.Keeping-after inserting until cementing medium solid, at least one minute, it should be removed surplus cementing medium in time.
6.Completing-after jointing at least 10 minutes pipes should be not exerted loading. After 48hours pipeline can go on water test.

R-R elastic rubber sealing ring jointing procedure

1. Socket slot inside surface and spigot outside surface should be cleaned by cotton cloth.
2. Rubber sealing ring should be installed actually (big part inside, small part outside)and place the socket slot.
3. Pipe spigot should be marked inserting depth line.
4. Rubber sealing ring and pipe spigot uniform brush lubricant(prohibition oils).
5.using tight thread device or manual calabash drags only a time to the mark line.
6. Using plug ruler inspects rubber sealing ring installed among the circumference.
