UPVC pipe fittings, advantages of pipe
Lightweight: The proportion of UPVC material is only 1/5 of that of cast iron, which is easy to transport, install and reduce costs.
Superior chemical resistance: UPVC has excellent acid and alkali resistance, except for strong acid and alkali near the saturation point or strong Oxidising agents atmaximun.
Non-conductive: UPVC material can not conduct electricity, nor is it corroded by electrolysis and current, so there is no need for secondary processing.
Can not burn, does not support combustion, no fire concerns.
Easy installation and low cost: cutting and joining are very simple, and the use of PVC glue to join has proven reliable and safe, easy to operate and low cost.
Durable: excellent weather resistance, and can not be corrupted by bacteria and fungi.
Low resistance and high flow rate: the inner wall is smooth, the loss of fluid fluidity is small, and the dirt is not easy to adhere to the smooth pipe wall, the maintenance is relatively simple, and the maintenance cost is low.
PVC
PVC is polyvinyl chloride, which is a general term for polyvinyl chloride compounds. There are soft polyvinyl chloride (SPVC), rigid polyvinyl chloride (RPVC), and plasticizer-free polyvinyl chloride (UPVC) in polyvinyl chloride. , The main difference is that the amount of plasticizer added is different, SPVC plasticizer is more than 25 parts, RPVC plasticizer is less than 5 parts, and plasticizer addition is more than 5 parts and less than 25 parts is called semi-rigid PVC, no plasticizer is added. The plasticizer is called UPVC.
Stabilizers are added during PVC production, but the stabilizers are divided into non-toxic and toxic. Only when toxic stabilizers such as lead salts are added, will there be hidden dangers. However, PVC products are mixed, and some small enterprises use lead salt as a stabilizer, which makes it difficult to meet relevant hygiene standards. When consumers choose PVC materials, it is best to go to the building materials market with guaranteed credibility and quality, and ask the supplier to issue a test report. Consumers should pay attention to checking relevant documents and signs, and only products that have obtained the Sanitation License for Products Involving Drinking Water Sanitation and Safety are safe.
