The Pros and Cons of PVC for Water Well Installations

Drillers have installed wells using PVC materials for decades. Companies make PVC casing and fittings, and even PVC screen &#; the components of the whole well system. However, advancements over time have meant that PVC in the field today outperforms the materials contractors had access to when HDPE gained widespread use in the s.

Broadly, the &#;recipes&#; companies use to make polyvinyl chloride, better known as PVC, have gone through subtle changes. Contractors may not know from just looking at the finished product, but today&#;s PVCs tend to have more corrosion resistance and durability than earlier generations. That makes it a cost-effective option for well installations, even in harsh environments.

Modern PVC pipe can also provide more flexibility. &#;Flexible&#; PVC is a type of PVC designed to install in wells located in difficult-to-access areas. Flexible PVC is also more resistant to breakage, which can help to prevent leaks in such wells.

Finally, there have been advancements in the methods used to join PVC pipe. Traditional methods of joining PVC pipe, such as solvent cementing, can prove time-consuming for contractors and difficult correctly execute. Newer methods of joining PVC pipe, such as mechanical joining, are faster and easier to do. Mechanical joining also provides a stronger and more reliable joint than traditional methods.

The advantages of using PVC materials in water well construction include:

• Strength and durability: PVC pipe can withstand the harsh conditions found in many wells. It resists corrosion over time.
• Environmental friendliness: PVC pipe does not contain any harmful chemicals that can leach into groundwater. PVC materials can also be recycled at the end of their life.
• Ease of installation: PVC pipe is relatively easy to install, which can save time and money on the well construction project.
• Cost-effectiveness: PVC materials are a cost-effective choice for water well contractors versus other materials.
• Long life: PVC materials offer a long life, and they can help to ensure a long and trouble-free life for your well.

Of course, every material can have trade-offs. PVC is no different and contractors should consider these factors in sourcing decisions. PVC is:

• Strong, but not as strong as steel: PVC may not be a good option for applications with very high water pressure or the potential for a lot of ground movement.
• Not as chemical resistant: PVC is susceptible to damage from chlorine and ammonia. The former can make PVC brittle and the latter can cause it to swell or deform.
• Not as easy to repair: A leak in a PVC well may prove more difficult or expensive to repair versus other materials.

PVC pipe, casing and fittings have proven popular for contractors (and their customers) for many years. Their popularity only grows as companies develop advances in their products. Drillers have materials options when it comes to well installation. PVC has improved over time and contractors should give it another look if they haven&#;t in a while. It could be just the thing you need to offer your customers a trouble-free water well that lasts a lifetime.

Truck-mounted water well drilling rig is a kind of professional machinery and equipment with advanced structure, and its excellent performance greatly improves the drilling speed and efficiency, which is popular with people. So, what are the advantages of truck-mounted water well drilling rigs? Let's find out.

1. The water well drilling rig installed in the car is light in weight and easy to move. The weight of the submersible drilling rig is less than 500Kg, and it can be divided into three lathes for easy movement.

2. Truck-mounted water well drilling rig adopts a high-performance reducer to generate rotary force by the motor and thrust by the cylinder. Realize high mechanical efficiency, low cost, and stable performance.

3. Rolling pallets are used for water well drilling rigs on ships, and the tracks are not easy to wear.

4. The water well drilling rig installed on the car has an oil-proof function. If the drill bit is stuck, the motor will be difficult to drive and the reducer will not be easily damaged.

5. The drilling rig mounted on the vehicle adopts semi-automatic rolling and dismantling drill pipe, with high working efficiency.

The working process of the water well drilling rig installed on the vehicle cannot be separated from the use of the pump, which is used for the reverse circulation operation. Under the influence of atmospheric pressure, the circulating fluid flows from the settling tank along the annular gap of the wellbore through the backflow channel to the bottom of the well. As the turntable drives the drill pipe, the drill pipe rotates the drill bit to drill the hole, which is manufactured by the suction pump.

The negative pressure draws the debris mud into the inner cavity of the drill pipe, then rises to the outlet and is discharged into the settling pond by the mud pump. The circulating fluid continues to flow into the wellbore, creating a reverse circulation drilling operation. Mud or water enters and exits the water source from the drill pipe of the positive circulation drilling rig. The mud or water is sucked out of the drill pipe and out of the water source (reverse circulation rig).
