PVC (polyvinyl chloride) pipes are widely used in many fields because of their unique properties, especially in scenarios where grooving (drilling) is required to meet specific installation requirements. The following are the characteristics and advantages of PVC pipe in grooving (drilling) :
1. Strong corrosion resistance
Chemical stability: PVC pipe has excellent chemical stability and can resist the erosion of a variety of acid and alkali substances, which means that during the grooving or drilling process, even if it is exposed to certain chemicals, it will not cause damage to the pipe.
Environmental adaptability: Whether in wet, dry or corrosive environments, PVC pipe can maintain its performance unchanged, suitable for a variety of complex environments.
2. Long life
Durability: Compared with traditional pipe materials, PVC pipe has a longer service life at set temperatures and pressures, usually up to more than 50 years, reducing the frequency of replacement and maintenance.
Anti-aging: PVC material has good anti-aging properties, can resist the erosion of natural factors such as ultraviolet light, oxidation, and maintain long-term stability and durability.
3. Excellent hygiene performance
Non-toxic and harmless: PVC pipe produced with tin or Ca/Zn stabilizer, its health performance is fully in line with the relevant national standards and the water quality standards of the Ministry of Health to ensure safe water quality and no pollution.
Easy to clean: the surface of the PVC pipe is smooth, not easy to accumulate scale, easy to clean and maintain, and ensure the cleanliness and hygiene of the water quality.
4. Good slotting (drilling) rate and pressure resistance
Machinability: PVC pipe has good machinability, easy to groove (drilling) and other secondary processing operations, to meet the specific installation needs.
Strong pressure resistance: PVC pipe has high compressive strength and toughness, can withstand a certain external impact and pressure, to ensure the stability and safety of the pipeline system.
Stable performance: After grooving or drilling, the performance of PVC pipe is still stable, and its original performance will not be reduced due to the processing process.
Tensile Strength
The required tensile strength can be calculated according to the weight of the pipe. In addition to the column weight, the gravel stuck in the joint during the assembly and settling stages should also be considered in the design calculation. When opening a well or pumping water (due to the large water level difference), the low bearing capacity of the slotted screen should be considered. The effects of this pressure cannot be precisely determined. As the pipe passes through the clay layer, additional compressive forces are applied due to the expansion of the clay. This can occur at any depth and in extreme cases can cause considerable strain on the surface of the material. The values shown in the table in this manual are based on the minimum wall thickness, diameter and material composition of the pipe.
Impact of Temperature
The mechanical properties of PVC-U well pipe are affected by the prevailing temperature conditions in the laying process. At high temperatures between 30 ° C and 40 ° C, the relationship between creep strength and time indicates that PVC-U material properties provide a sufficient safety factor for the intended use. However, it is important to identify other factors that affect the sealing of a borehole with a well tube wrapped in concrete. The hydration heat of concrete can cause the temperature to rise. However, calculations show that these temperatures usually do not exceed 15°C. When the temperature of the unset concrete reaches. 18°C, the temperature inside the seal will be slightly higher than 30°C, which is in the optimal range.
