Key Precautions For Storage And Construction Of UPVC Pipe And Valve Components

1.During the unloading and installation process, it is strictly prohibited to drop, throw, throw or smash goods.

2.The inventory location should be indoors or in a cool place, away from heat sources or dangerous goods; It is strictly prohibited to mix pipes and fittings.

Directly exposed to outdoor high temperature environments. High surface temperature in summer (up to 50 ℃ or even 60 ℃).

Above, it is extremely easy to cause deformation and bending of pipes and fittings.

3.During the hot summer season, it is necessary to store pipes with woven bags outdoors for special circumstances.

When unloading materials, directly remove the packaging or cut both ends of the packaging, and then store them neatly, as the pipes are wrapped.

Inside the woven bag, it is not easy to dissipate heat and will accelerate the deformation and bending of the pipe material; In addition, it is necessary to isolate the pipes from the air.

Breathable.Sunshade to avoid direct exposure to sunlight.

4.The storage area for pipes should be flat and neatly stacked; The stacking height of DN150 and above specification pipes is not high.

Should exceed 1 meter; The overhead length should be appropriate to avoid bending of the pipes.

5.Outdoor construction and installation in summer should be carried out in the early morning or evening when the temperature is lower.

6.Installation precautions:

• The glue should be applied evenly, and the amount of glue should be applied. After the pipe is pushed into the pipe fitting, there should be a slight extrusion of glue at the end of the ring water, and there should be no gaps at the ring end.

• It should be spliced when the adhesive is in a moist state, and the insertion process should be done in one step to avoid intermittency. Twice twist the pipe fittings to ensure the reliability of curing.

• Installing larger diameter pipes and fittings requires cooperation from multiple people and can be used in conjunction with actual situations tightener.

• Water is strictly prohibited within 48 hours after installation.

• If the straight length exceeds 30 meters, expansion and contraction soft joints should be installed according to the actual situation or regulations.

• It is prohibited to lock pipes and fittings with clamps and pipe codes to prevent them from being locked under the force of thermal expansion and contraction the phenomenon of detachment or bending.

7.Response measures for using quick drying adhesives to cure too quickly in summer:

• The use of cleaning agents can provide the first softening effect and prolong the curing time.

• Mix and add slow drying adhesive in an appropriate proportion to extend the curing time.
