Plumbing is one of those elements that most of us don't think about until we have a problem, usually in the form of leaks, damp walls, or novel odors. In a country like Nepal, where the temperature can range from freezing cold winters to blistering summers, the right pipe selection becomes far more important than one appreciates. A good set of tiles or nice bathroom fixtures might glisten, but the only true strength of a house lies behind the walls.

Dolphin Polyplast has made a name for itself in Nepal for durable plumbing solutions with its entire range of CPVC, UPVC, Borewell, and Underground pipes. Each of these types of pipes has been developed for a specific use, and knowing the differences between them, while recognizing the right solution, can save you money and stress in the long run.

This guide will walk you through how each Dolphin pipe works with respect to what the pipe is typically best suited for, as well as how to choose the best Dolphin pipe option based on your home or building.

Why Selecting the Right Pipe is Important in Nepal

Homes and buildings in Nepal face unique considerations. Many homes and buildings are depending on borewell water, which may be mineral-heavy or have other characteristics... Rooftop pipelines are exposed to sunlight daily. Multi-storey homes and buildings are pressurized.

Underground drainage pipes must endure moisture and load from soil for many years.

Using the wrong pipe can lead to:

1. Early cracking from heat or UV exposure
2. Rust and mineral build-up
3. Hidden leaks that harm drywall
4. Contamination in drinking water
5. Costly repairs after a few years

6. A good plumbing choice provides normal water flow, better hygiene, and stable longevity.

    

Dolphin Pipes: Designed for Nepali Homes and Weather

However, the aspect that distinguishes Dolphin from the competition is its emphasis on strength, safety, and durable materials that go from carrying hot water to the pressure deep within the ground.

It’s helpful to know the intended function of each pipe prior to selecting one.

CPVC Pipes – Suitable for Hot Water & Hygiene Applications

What CPVC Pipes Are

CPVC stands for Chlorinated Polyvinyl Chloride. CPVC is a temperature-resistant material used for water supply. CPVC does not reacts with water. CPVC neither rusts nor softens when passed by the flow of hot water.

Why CPVC Is a Popular Choice?

If your home is utilizing geysers, solar heaters, or hot water pipes, the safest material will be CPVC. CPVC does not get harmed by heat like normal PVC.

Chief Merits of CPVC

1. Heat resistant to 93°C - ideal for showers and the kitchen.
2. Does not rust or scale back because minerals in water won't clog it.
3. Safe for use in drinking water - made from non-toxic materials.
4. Can handle high pressure. Well suited for high-rise buildings.
5. Simple installation - lightweight & easy assembly.

Where CPVC Performs Best

1. bathrooms
2. Kitchens
3. Geysers & Solar Heaters
4. Hotels and business areas

5. High pressure lines in tall structures

    

Comparison Between CPVC and Other Hot Water Pipes

Hot water processing will make CPVC the most reliable material.

UPVC Pipes – Best for Cold Water & Outdoor Use

What UPVC Pipes Are

UPVC = Unplasticized PVC. This pipe is very strong and lightweight. It is better suited for cold water supply work. Since plasticizer is not used in UPVC pipes, it retains its strength.

Why UPVC is Suits in Nepal

Outdoor pipes are exposed to strong sun, temperature variations, dust, and moisture. UPVC is designed to withstand all the aforementioned without breaking or discoloring.

Major Benefits of UPVC

1. UV-stabilized - ideal for rooftop and exterior feed.
2. No rust/no chemical reaction - safe for use in borewell water.
3. Lightweight but robust - very easy to handle & erect.
4. Leak-proof joints - the solvent cement prevents any leakage.
5. Budget friendly - ideal for big projects and residential colonies.

Where UPVC Works Best

1. cold water pipes
2. overhead tank supplies
3. exposed outdoor pipelines
4. agricultural water use

Void & Drainage Lines

Since the requirement may involve cold water or anything that is exposed to the sun, UPVC is the best option.

BOREWELL PIPES – Robust Pipes for Deepwater Extraction

What Are Borewell Pipes?

Borewell pipes are made for submersible pumps. These pipes work in underground water. Deeper water produces higher pressure on the pipe. Minerals like iron salt also affect borewell pipes.

Why Borewell Pipes are Important?

A borewell system is no better than its pipe. Poor-quality pipes might clog beneath the ground. This could involve significant repairs.

Important Characteristics of Borewell Pipes

• Higher tensile strength. Designed for deep borewell pressure.
• Non-corrosive. Immune to iron, saltwater, and mineral water.
• Safe for drinking water - no chemical leaching.
• Leak-proof threaded connections - safe for submersible pumps.
• Long-lasting underground durability. Designed for extreme underground conditions.
•  

Selecting the Right Borewell Pipe

Always use an higher duty pipe for deep installations.

Underground Pipes – Best for Drainage, Wastewater & Sewage

Underground pipes are able to withstand the pressure from the soil. Such pipes are used in the process of draining water.

Why Underground Pipes Are Important

Failure of the underground drain line may result in floods, damage to the foundation, and costly repair work. Hence, reliability becomes the pioneering requirement.

Major Advantages of Underground Pipes

1. Higher carrying capacity - ideal for road constructions.
2. Impact Resistant - doesn't rupture from soil movements.
3. Chemical Resistant - ideal for industrial waste.
4. Designed for Long-term Waste Flow. Does Not Cause Blockages & Leaks.

Where Underground Pipes Are Used?

However, in the event the pipe goes underground, the best pipe to use is the underground pipe.

   Outdoor → UPVC
3. Use Borewell Pipes for the borewell systems.
   It is resistance to pump pressure, depth, and minerals.
4. Then for the Drainage/Sewage system in the <u
   Designed for long-term waste flow.
5. Request for Quality Certifications
   ISO and food grade certificates signify safety.
