What are the steps to use PVC pipe fittings?

PVC pipe fittings are made of PVC resin modified by chlorination. It not only preserves the excellent properties of many PVC materials, but also further improves these properties, allowing it to be used in a wider range of applications and has a longer service life.

What is the production of PVC pipe fittings?

The production of PVC pipe fittings is that after the chlorination of PVC resin, the irregularity of molecular bonds increases, the polarity increases, the solubility of the resin increases, and the chemical stability increases, thereby improving the heat resistance, acid resistance and corrosion by alkalis, salts, oxidants, etc. The mechanical properties of the heat deformation resistance of the resin are improved, the chlorine content is increased from 56.7% to 63-69%, the Vicat softening temperature is from 72-82℃ to 90-125℃, and the maximum operating temperature can reach 110℃ and can be used for a long time.

What are the application areas of PVC pipe fittings?

1. Calendered sheet metal: It can be used for making chemical resistant and corrosion resistant chemical equipment such as reactors, valves, electrolysers, etc. use.

2. Composites: PVC pipe fittings made of CPVC and some inorganic or organic fibers have good impact resistance and heat resistance than other resin composites, and can make plates, pipes, corrugated board, profiles, etc. processing.

3. PVC pipe fittings can be used to modify polyvinyl chloride fibers: the washing and drying temperature of polyvinyl chloride fibers should not exceed 60°C, and the addition of 30% CPVC when spinning polyvinyl chloride can greatly improve the heat resistance of the product and reduce shrinkage. The quota fell from 50% to below 10%.

What are the steps to use PVC pipe fittings?

1. Data preparation: position pipe or pipe fitting straight and place it on the docking machine, leaving 10-20mm cut allowance.

2. Clamps: Select the suitable slide clamp according to the welded pipe and pipe fittings, clamp the pipe and prepare it for cutting.

3. Cutting: Cutting the welded pipe sections, impurities and oxide layers on the end faces of the pipe fittings, to ensure the two blunt end faces are smooth, clean and free of impurities.

4. Alignment: The end faces of the two welded pipe pieces should be fully centered. The smaller the wrong side, the better. The wrong side should not exceed 10% of the wall thickness. Otherwise, the quality of the butt joint will be impaired.

5. Heating: The docking temperature is generally between 210-230 ℃, the heating time of the heating plate is different in winter and summer, and the melting length of both ends is preferably 1-2mm.

6. Switching: Remove the hot plate, quickly glue the two hot melt adhesive end faces together and put pressure. In order to guarantee the quality of the melt stroke, the shorter the switching time, the better.

7. Melting butt joint: It is the key point of welding. The butt joining process should always be carried out under the melting pressure and the width of the rolling edge should be 2-4mm.

8. Cooling: Keep the docking pressure unchanged and let the interface cool down slowly. The cooling time depends on the roughness of the rolling edge and the feeling without heat.
