What are the advantages and disadvantages of PPR plastic pipes compared with steel pipes?
Copper plastic and stainless steel composite pipes, etc. and plastic pipes (including PE, PPR, PVC, etc.) are compared. Strength comparison, the most commonly used stainless steel water industry, plastic pipe expansion coefficient is too large, is its Achilles heel, not suitable for hot water pipes. In the condition of environmental temperature change, plastic pipe leaks easily and so on
Power cost;4, corrosion resistance: with good acid, alkali, chemical resistance, electrical resistance, good corrosion resistance, the use of pitting will not occur;5 、 easy to install: flexible connection, rubber ring seal, easy installation, good sealing;6, long life: under normal working conditions, the service life of up to 50 years;7, non-toxic hygiene: in line with drinking water standards, the transmission of water from the two pollution;8, low cost: transportation and installation costs low, material costs cheaper, the total cost of the project than the cast iron pipeline savings of 30%.
Advantages and disadvantages are as follows:1, light weight: unit length, weight is only 1/6 of cast iron pipe;2, high strength: tensile strength of more than 45Mpa;3, small resistance: pipe wall smooth, no fouling, the same caliber pipe along the head loss is more than 30% lower than cast iron pipe, can save a lot of operation
