Aquifer storage and recovery

In ASR systems, slotted pipe is installed in wells or boreholes that penetrate the aquifer, plays a crucial role in facilitating water injection and extraction in aquifer storage and recovery systems, thus enabling efficient storage and retrieval of water from the subsurface aquifer.

Environmental industries

Filson slotted pipe is widely used in various environmental protection areas, including groundwater monitoring, oil well development, waste infiltration fluid collection, geothermal systems, etc. The excellent performance ensures optimal environmental protection effect.


In borewell, slotted pipe is commonly used to extract water from underground aquifers and form a protective barrier against sediment and debris. Filson slotted pipe has standard design, precise size and excellent quality to ensure drawing clean water efficiently from borewell.

Tube well

Slotted pipe is usually installed in the part of tube well intersects the aquifer, capturing impurities such as soil, sand and debris before water enters the well. It effectively ensures extracting water from underground aquifer, while providing protective barrier against sediment and debris.

Various wells including oil, mines, industrial, etc

including oil, mines, industrial, etc.

Slotted pipe plays an important role in many wells in domestic, agricultural and industrial fields, ensuring the best performance of wells and preventing blockage by impurities. It is widely used in water well, monitoring well, geotechnical well, restoration wells, oil and gas wells, etc.

Ground water

With high corrosion resistance and non-toxic properties, Filson slotted pipe is often used to collect and recover ground water. It provides strong passage for rainwater to penetrate back into the surrounding area,  and it also collects rooftop rainwater to replenish the groundwater.

Rain water collecting

What are the Factors may Cause the Deformation and Burst of Slotted Pipe?

What are the Factors may Cause the Deformation and Burst of Slotted Pipe

To avoid pipe deformation and bursting, bore mechanics should take care of the following information:

  • Hydraulic pressure difference caused by inside and outside water during drilling
  • Hydraulic pressure and heat generated by bentonite or cement grout
  • Stress formation for rocks, clay and shale outside the pipe
  • Lateral compression and brittle risks for external impact of the hard stone
Are Slotted PVC Pipes Better Than Slotted Metal Pipe?

 Are Slotted PVC Pipes Better Than Slotted Metal Pipe

For Filson PVC-based slotted pipe, it has salient advantages, such as lightweight, easy to transport and install, high resistance to temperature and corrosion.

More importantly, it is non-toxic, which means it will not impart any taste, odour color or generate any harmful substances, hence it is a desirable solution for potable or drinking water fields. And it has longer service life than metal-based slotted pipe.

For Filson metal-based slotted pipe, it has higher mechanical strength than slotted PVC pipe, which allows it to suffer higher external pressure. It can be made into any shapes, like square. Adding other coating materials, it can be endowed with higher resistance to corrosion or other chemicals.

Therefore, whether PVC or metal slotted pipe, the best one is based on your applications and industries. If you still do not know, please contact us, our professional experts will choose the best and suitable one for you.

Where is the Slotted Casing Pipe used for?

Where is the Slotted Casing Pipe Used for

Slotted casing pipe is mainly used in borewell, especially collapsible or sandy-loose soil, and slit, to protect and be supported apart.

What is the Specialty of Filson Slotted Pipe?

 What is the Specialty of Filson Slotted Pipe

Filson slotted pipe is special because its slot opening will not hurt its mechanical strength, because its slot opening is vertical to the axis of the pipe, rather than the length of the pipe. It is done by advanced machines and experienced workers.

What are the Types of Tube Well?

There are three types of tube wells: strainer well, cavity well, and slotted well.

  • Strainer types tube well: It is the most common tube well and consists of blind pipes and strainer pipes or screen pipes, which are alternately placed. The strainer pipes rest against aquifers and the blind pipe rests against impervious strata. The strainer types tube is not suitable for fine sandy strata, which are easily choked.
  • Cavity-type tube well: It has an underground pipe and gets its supplier from the bottom. At first, it produces sandy water, but when the cavity’s spherical area expands, sand particles can be blocked. It only accesses one special aquifer compared to a strainer-type tube well.
  • Slotted type tube well: It is slotted at one end and the rest parts is plain pipe. It can compress air to develop the well. In order to prevent fine sand from entering, the slotted-type tube well is surrounded by gravel and coarse sand. Slotted-type tube wells can only tap one strata while strainer wells can tap more.
