Compared with traditional pipes, polyvinyl chloride pipes have the following advantages:
① Lightweight: The specific gravity of polyvinyl chloride material is only 1/10 of cast iron, with low transportation costs and easy installation.
② Superior chemical resistance: It has excellent acid and alkali resistance.
③ It is non-conductive and not subject to electrolysis, and is not corroded by electrical currents.
④ Flame retardant PVC pipes cannot burn or support combustion, they will only be burned and deformed, without any fire safety concerns.
⑤ Easy installation and low cost: cutting and connecting are both simple, using PVC glue for connection, which has been proven to be reliable, safe, easy to operate, and cost-effective.
⑥ Durable: Excellent weather resistance and cannot be corrupted by bacteria and fungi.
⑦ Low resistance and high flow rate: The inner wall is smooth, the fluid flow loss is small, and dirt is not easily attached to the smooth pipe wall. Maintenance is relatively simple and the maintenance cost is low.
Methods for distinguishing the quality of polyvinyl chloride pipes
① First, check the surface smoothness and Baidu. A surface that is smooth and has a relatively bright whiteness is of the highest quality.
② Samples that are prone to breakage are usually high calcium products.
③ Take the sample and step on the edge of the pipe to see if it can crack or the elongation at break after cracking.
④ In terms of endurance. The most direct way is to take it to a place with high temperature and light for a few days, observe the surface change rate, and determine whether it can withstand the baptism of high temperature and sunlight. This method can directly determine the quality of PVC pipes, but it is too time-consuming.
