Is CPVC better than PVC?
Not only can CPVC be used above the maximum service temperature of PVC, but its increased temperature resistance enables it to perform better at temperatures within PVC's working range. For example, even below 140°F (60°C), CPVC is superior to PVC in terms of impact strength and tensile strength.
What is CPVC?
CPVC (chlorinated poly (vinyl chloride) is a strong and rigid thermoplastic material that is used for hot and cold potable water applications in residential construction. Because of its makeup, CPVC is immune to damage from highly chlorinated domestic water and has a higher temperature tolerance than PVC.
Which types of pipes are used for water supply and waste water collection?
PVC Pipes. Polyvinyl chloride pipes (PVC) are commonly used as part of a sink, toilet, or shower drain line. ... PEX Pipes. PEX, or cross-linked polyethylene, piping also refers to an affordable plastic tubing commonly used for water supply lines. ... ABS Pipes. ... Copper Pipes. ... Cast Iron and Galvanized Steel Pipes.
Which pipe is best for drainage?
PVCPVC (Polyvinyl Chloride) One of the widely used pipes for all drainage systems is PVC pipes. They are highly resilient and sturdy making them suitable even in the harshest conditions. Additionally, their durability ensures longevity-a major condition in underground systems.
Why is PVC used for water pipes?
PVC pipes are a safe choice for transportation of drinking water. This is due to their high degree of inertness and resistance to corrosion. PVC pipes are therefore free from bio-film contamination that can be a breeding ground for bacteria. By helping provide clean water, PVC pipes are beneficial to public health.
What is the life of CPVC pipe?
50 to 75 yearsAccording to the experts at the International Association of Certified Home Inspectors (InterNACHI), CPVC pipes are expected to last for 50 to 75 years under optimal conditions.
What are the uses of polyvinyl chloride?
Polyvinyl Chloride (PVC) is one of the most widely used polymers in the world. Due to its versatile nature, PVC is used extensively across a broad range of industrial, technical and everyday applications including widespread use in building, transport, packaging, electrical/electronic and healthcare applications.
What is CPVC used for?
Essentially, anywhere piping is used to convey a fluid or other medium , CPVC is an option.
What is CPVC thermoplastic?
An advanced thermoplastic, which builds upon the advantages of PVC, is chlorinated polyvinyl chloride (CPVC). Commercialized by Lubrizol nearly 60 years ago, CPVC is a specially engineered thermoplastic with excellent corrosion resistance, impact strength and temperature resistance. The need for a consistent quality thermoplastic was a leading factor in Lubrizol creating the Corzan CPVC technology. Today, it is one of the most specified industrial CPVC materials in the world. Engineers have confidence in Corzan CPVC, regardless of the manufacturer, and specify around the technology.
How many wastewater treatment plants are there in the US?
Each year in the United States, an estimated 61 cubic kilometers of wastewater are treated by plants—roughly the volume flowing over Niagara Falls in a year. Nearly 15,000 wastewater treatment plants in the U.S. today treat sewage water, polluted agricultural water and industrial plant wastewater.
What is the corrosive environment of wastewater treatment plants?
The corrosive environments of wastewater treatment plants typically pass on metals in preference of plastic piping. Plastic piping is inherently resistant to many of the contaminants in wastewater and the treatment process, such as salts and minerals, and the chemicals used to treat the water, including strong acids and bases.
Does Corzan CPVC stand up to acids?
In fact, CPVC pipes and fittings effectively stand up to most acids, bases and salts .
What is CPVC piping?
CPVC piping can be used virtually anywhere piping is employed to transport fluid or another medium, as illustrated above. Corzan CPVC piping systems save installation time and offer many performance and maintenance advantages. They are also durable and reliable over the long term.
How is CPVC pipe fused?
CPVC piping is fused using a straightforward, two-step solvent cement process. Solvent cementing requires about half the time to join pipe and fittings compared to welding. Solvent cement chemically fuses the CPVC pipe to the fitting for a highly reliable joint that becomes the strongest part of the entire piping system. These joints are able to withstand the harsh chemicals, high temperatures and pressures present in wastewater treatment plants. Any trained mechanical contractor or plant maintenance engineer can change, repair, or modify a CPVC piping system without specialized equipment. Proper training is essential however, as incorrectly applied solvent cement or cement used in the wrong application can cause joints to fail. Training is available through your local RHFS Service Center.
Why is metal piping used in wastewater treatment?
Metal piping is seldom an option for wastewater treatment plants because of the highly corrosive environment.
How much does Corzan CPVC weigh?
Corzan CPVC’s comparably low installation cost reflects the fact that its significantly faster and easier to install than traditional metal systems. CPVC weighs 1/8th as much as comparably sized steel piping. A 6” schedule 80 Corzan pipe weighing about 6 lbs per foot compared to 25-29 pounds per square foot for the same size steel piping. The weight difference translates into fewer workers required to handle, install, and secure the CPVC piping. The system is also easier to install in close quarters, with no need for heavy equipment to lift the piping material into place.
Why use Corzan industrial piping?
Water and wastewater treatment plants find reliability and confidence in Corzan Industrial Piping because it: Eliminates internal and external corrosion caused by corrosive chemicals. Blocks the degrading effects of chemicals, microorganisms and UV light. Achieves long-term performance with superior mechanical strength and ...
How does corrosion affect water treatment plants?
Corrosion to pipes, valves and fittings caused by chemicals and microbes can greatly impact the bottom line at water and wastewater treatment plants. Engineers and procurement officials must find cost-effective technologies that ensure quality and reliability.
Does Corzan CPVC work for reverse osmosis?
DESALINATION SYSTEMS: In desalination applications, Corzan Industrial Systems can handle the chemical feeds for reverse osmosis processing. Since Corzan pipe and fittings are not susceptible to attacks from high chloride levels, there is no need to pickle or passivate the piping system and no need for expensive cathodic protection against corrosion. And with its ability to resist ozonated water, high temperatures and UV rays, Corzan CPVC is cost-effective for potable water service in coastal and desert environments with growing water shortages.
