What is a pipe?

A hollow tube with a round cross-section is a pipe. For piping and pipeline systems, the pipe is frequently used. A pipe is a long, hollow, spherical object that is typically made of plastic or metal and allows for the flow of liquid or gas. For the transportation of drinking water, wastewater, chemicals, heating, and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gasses, compressed air, irrigation, plastic pressure pipe systems, and vacuum system applications, plastic pipe is used. 

Types of popular plastic pipe in Nepal:

HDPE pipe

The mains pipes made of aging concrete or steel are frequently replaced by HDPE pipe, a flexible plastic pipe type used for the transfer of fluids and gases. Because of its high level of impermeability and solid molecular bond, high pressure pipes can use this HDPE (high-density polyethylene) thermoplastic material. HDPE pipe is strong, resistant to chemicals, corrosion-resistant, and lightweight. HDPE pipe is a tough, adaptable thermoplastic with excellent impact and tensile strength.

Polyethylene pipe

Polyethylene pipe is known as PE pipe. Thermoplastic polymerized ethylene is used to create polyethylene (PE), a material. For a wide range of applications, such as potable water service or distribution lines, natural gas distribution, lawn sprinklers, sewers, garbage disposal, and drainage lines, PE pipe is an excellent piping material. PE materials typically resist the majority of common chemicals. For potable water and wastewater delivery, polyethylene pipe is suitable.

Chlorinated Poly Vinyl Chloride Pipes (CPVC)

CPVC pipes are renowned for their resistance to physical and chemical deterioration, which extends their lifespan. This type of non-corrosive pipe can be used for cold and hot (around 180°F). It is durable and easy to use. CPVC differs from PVC in that it undergoes a free radical chlorination process, which essentially raises the material's chlorine concentration. CPVC is a thermoplastic that may be molded into a variety of goods. It is feasible to withstand a wider range of temperatures. 

Benefits of CPVC pipe

• rust / corrosion resistance

• Bacteria resistance

• Chemical resistance

• Fire prevention

• Leak proof

Unplasticized polyvinyl chloride Pipes (uPVC)

In both residential and commercial structures, rigid PVC pipes and fittings, also referred to as uPVC (unplasticized polyvinyl chloride) pipes, are used for all plumbing needs. UPVC is referred to as having strong resistance to chemicals, UV, and water oxidation. UPVC is frequently used in building because it is strong, affordable, and simple to deal with. UPVC is a strong, sinewy, transparent, and long-lasting polymer that resists the effects of air pollution, dampness, and a variety of chemicals. Additionally, it possesses minimal flammability and excellent electrical characteristics.

Benefit of upvc pipe

• Lead-free

• ultraviolet protection

• Chemical resistance

• Resistance to pressure

There are some notable distinctions between CPVC and PVC, despite the fact that the two pipes even appear similar.
