One, what is an upvc pipe?
UPVC pipe is a plastic pipe material made from polyvinyl chloride (PVC) resin, without plasticizers.
Two. What temperature range can UPVC pipes withstand?
UPVC pipes have poor heat resistance, and their tensile strength decreases at temperatures above 60°C (suitable for continuous discharge temperatures not exceeding 40°C and instantaneous discharge temperatures not exceeding 80°C). Therefore, when designing, they should be kept away from heat sources, such as being at least 400mm away from the stove and at least 200mm away from hot water pipes. Hot water pipes should also be insulated and should not pass through chimneys or firewalls.
Under low-temperature conditions, the impact strength of rigid PVC plastic drainage pipes decreases. Therefore, in areas with air conditioning systems, it is recommended to replace rigid PVC drainage pipes with cast iron pipes to ensure drainage safety.
Due to its large temperature sensitivity and expansion coefficient, each vertical pipe and longer horizontal pipe requires the installation of expansion joints.
Three. Performance characteristics of UPVC pipes
1、Excellent physical and chemical properties
UPVC pipes offer excellent corrosion resistance, high impact strength, low fluid resistance (30% higher flow rate compared to cast iron pipes of the same diameter), aging resistance, and long service life, making them ideal materials for building drainage and chemical effluent applications.
2、Lightweight and practical, easy to install.
UPVC pipe weighs only 1/7 of that of a cast iron pipe of the same diameter, which can significantly accelerate construction project progress and reduce construction costs.
3. Reduce construction costs
Using UPVC pipes results in a lower overall cost compared to using cast iron pipes of the same specifications, and also reduces maintenance expenses.
