Plastic pipework is used for drinking water, wastewater, chemicals, gases, and foodstuffs
Plastic pipework is used for a variety of purposes, including the conveyance of drinking water, wastewater, chemicals, gases, and foodstuffs.
Plastic pipes are a versatile and durable solution for the transportation of drinking water. They have been used for this purpose since the 1950s and are known for their reliability and safety. Polyethylene (PE) pipes are commonly used for potable water applications and have been rigorously tested to ensure that they do not adversely affect water quality. These tests include evaluations of taste, odour, and appearance, as well as assessments for the growth of aquatic microorganisms.
Plastic pipes are also widely used for wastewater management. They are an effective solution for transporting wastewater from buildings to treatment plants and are preferred for their superior flow-rate properties and low leakage. Plastic pipes are lightweight, easy to install, and have a long life expectancy, often exceeding 100 years. They are also flexible, allowing them to adjust to ground movements and reducing the risk of blockages.
In terms of chemical applications, plastic pipework made from materials like polyvinylidene difluoride (PVDF) and polypropylene (PP) is used in the chemical industry due to its non-reactivity, chemical resistance, and durability. These pipes are suitable for handling aggressive and corrosive solutions, making them ideal for chemical processing.
Plastic pipes are also used for the conveyance of gases, such as natural gas. They are typically thinner and lighter than steel pipes and are commonly used for smaller-diameter pipelines that transport low volumes of gas. Plastic pipes are generally preferred for gas applications because they are cheaper and easier to install.
Additionally, plastic pipework is suitable for use with foodstuffs and ultra-pure waters. Polypropylene, for example, is used within the food industry due to its high impact resistance, stiffness, and chemical resistance. It is also approved for use with potable water and in pharmaceutical applications.

Plastic pipes are made from thermoplastic materials and are produced by melting, shaping, and cooling
Plastic pipes are cylindrical tubes made from thermoplastic materials. They are used to convey liquids, gases, slurries, powders, and small solids. Plastic pipes are also used in structural applications, as they are stiffer per unit weight than solid members. They are commonly used for drainage systems, plumbing, and gas applications.
Plastic pipes are produced by melting the thermoplastic material and shaping it into a pipe form. This is done through a process called extrusion, where the material is pushed through an extruder and then cooled. Extrusion is a popular method for creating pipes as it reduces the chances of irregularities or deformities. The extruder system is subjected to high amounts of friction and stress due to the nature of the plastic, and so it must be built to high standards to withstand these working conditions.
PVC pipes are a type of plastic pipe that has been in use for over 80 years. They are exceptionally strong and durable, with complete corrosion resistance. They are also lightweight, recyclable, and cost-efficient. PVC pipes are commonly used for manufacturing sewage pipes, water mains, and irrigation systems.
Another type of plastic pipe is made from chlorinated polyvinyl chloride (CPVC). CPVC is resistant to many chemicals and has a higher maximum operating temperature than uPVC. This makes it suitable for residential, commercial, and industrial water and liquid transport. High-density polyethylene (HDPE) is another material used for plastic pipes, offering strength, flexibility, and lightweight characteristics.
Plastic pipes can also incorporate a flexible metallic layer as the middle of three bonded layers. This type of barrier pipe provides additional protection for the contents passing through the pipe, particularly drinking water, from aggressive chemicals or other pollutants.

Plastic pipes are corrosion-resistant, non-reactive, and have low heat conductivity
Plastic pipes are used to carry drinking water, wastewater, heating and cooling fluids, irrigation, compressed air, gases, chemicals, and other similar materials within a building. They are made from thermoplastic materials, with the production method involving melting the material, shaping it, and then cooling it.
Secondly, plastic pipes are non-reactive, meaning they do not react when in contact with dissimilar materials, unlike some metals. A common issue with metal piping is that when two dissimilar types are connected, they can react with one another and corrode. This is not an issue with plastic pipes.
Thirdly, plastic pipes have low heat conductivity, meaning they can handle a wide range of temperatures without warping or cracking, and maintain the temperature of the water inside without creating condensation, unlike uninsulated metal pipes. For example, polyvinylidene difluoride (PVDF) is a non-reactive, thermoplastic fluoropolymer with excellent chemical and thermal resistance for plastic pipework uses.
Overall, the variability of the material and its relative cost-effectiveness have made plastic pipes a popular choice for engineering plastics. They can be tailored to a range of applications by modifying the ratio of the individual chemical components.

Types of plastic pipes include CPVC, HDPE, PEX, and ABS
Plastic pipes are tubular sections, or hollow cylinders, made of plastic. They are used to convey liquids, gases, slurries, powders, and masses of small solids. Plastic pipes are used for drinking water, wastewater, chemicals, heating fluid, and cooling fluids, among other things. They are popular for their reliability, flexibility, and corrosion resistance.
There are several types of plastic pipes, including CPVC, HDPE, PEX, and ABS. Each offers unique benefits and is suitable for various applications, from residential plumbing to industrial systems.
CPVC, or chlorinated polyvinyl chloride, is resistant to many acids, bases, salts, paraffinic hydrocarbons, halogens, and alcohols. It can carry liquids at higher temperatures than uPVC, with a maximum operating temperature of 200 °F (93.3 °C). Due to its temperature threshold and chemical resistance, CPVC is recommended for residential, commercial, and industrial water and liquid transport.
HDPE, or high-density polyethylene, is a strong, flexible, and lightweight plastic pipe. It has a low coefficient of friction, which reduces water pressure and enables water to circulate more easily. HDPE pipes are eco-friendly, corrosion-resistant, and commonly used for plumbing.
PEX, or cross-linked polyethylene, is a type of plastic tubing used in plumbing or heating systems. It is strong, flexible, resistant to high temperatures, and long-lasting. PEX piping is very flexible and can be manipulated to go around corners and past obstacles without using multiple fittings and joints. This reduces potential leakage points and allows for quicker and more cost-effective installations.
ABS pipes are resistant to extreme weather conditions, including UV light exposure and cold temperatures. For this reason, ABS pipes are often used in outdoor plumbing applications.
