Lilok brand water well piping system is composed of well wall pipe and filter pipe, and the connection adopts high-strength threaded connection. It has a wide range of applications and can be divided into well wall pipes, water filter pipes, ventilation pipes, rainwater collection pipes, asphalt pipes, etc.

It is used in well drilling engineering; seepage drainage system; ventilation of grain depots; rainwater collection and reuse; agricultural muddy irrigation; sludge discharge in water plants and many other fields. It is also used in airports, railways, highways, sports fields, park green spaces, roof gardens, retaining walls, basements, fire roads, slope protection and drainage projects.

It can effectively reduce groundwater pressure, remove excess water, protect soil and buildings from damage due to seepage deformation, and protect flowers and trees from waterlogging.

Execution standard: CJ/T308-2009

Product Features:

Long service life: corrosion resistance, long service life, stable chemical properties, resistance to most acids, alkalis, salts and organic solvents, and can effectively prevent the occurrence of fragmentation during transportation, installation and use.

Good hygienic performance: The pipeline adopts organotin stabilizer, and the hygienic performance conforms to the GB/T1 7219 standard and the relevant water quality specifications of the Ministry of Health.

High opening rate: strong compressive ability and large amount of water passing through.

Easy to install: just like twisting a bottle cap, it is easy to operate and easy to install.

Advantages of PVC-U well pipe:

1. Long life:

Corrosion resistance, long service life, stable chemical properties, resistance to most acids, alkalis, salts and organic solvents, can effectively prevent the occurrence of fragmentation during transportation, installation and use, and ensure that the service life of the pipeline reaches and exceeds 50 years.

2. Non-toxic hygiene:

The pipe adopts organotin stabilizer, and the product strictly implements the "Standard for Motorized Well Pipe" (SL/T154-2013) and "Rigid Polyvinyl Chloride PVC-U Pipe for Water Well" (CJ/T308-2009) standard, and the hygienic performance conforms to GB/ T17219 standard and relevant water quality specification requirements of the Ministry of Health. No scaling during use, no growth of microorganisms such as algae, and no secondary pollution of water quality.

3. Large amount of water:

The inner wall is smooth, the hydraulic condition is good, the opening rate is high, and the compressive performance is stable. It is a good choice to replace steel and cement perforated pipes in many fields.

4. Easy to install:

The perforated tube is connected by a screw thread, which has good sealing performance, high connection strength and is not easy to pull out.

5. Light weight:

The weight per unit length is only 1/5 of the ductile iron pipe and 1/4 of the steel pipe. It requires less labor and construction equipment, and the construction cost is low.

6. Low cost:

The transportation, installation and material costs are low, and the total project cost is 30-40% lower than that of cast iron pipes.

Pipeline construction precautions:

When handling, loading and unloading pipes, it is strictly forbidden to throw or savage loading and unloading, so as to avoid damage to the pipes.

Before connecting the pipe and screwing the screw, apply soapy water to the screw to achieve the lubrication effect.

After the completion of the well pipe, when filling the filter material, fill the filter material slowly and evenly with a shovel.

Connection steps:

1. The water filter tube wraps the gauze;

2. Upper splint;

3. Pipe hoisting;

4. Tighten the screws.

Filter tube:

According to the shape of the filter hole, it can be divided into: slit pipe, round hole pipe;

According to the form of sticking gravel, it can be divided into: yarn production tube, gravel sticking tube;

According to the purpose, it can be divided into: filter pipes for wells, rainwater collection pipes, leachate collection pipes, etc.

Used for rainwater collection, airports, railways, highways, sports fields, park green spaces, roof gardens, retaining walls, basements, tunnels, slope protection drainage works, and mine tail dams, thermal power plant ash dams, and landfill leachate collection systems.
