18、tion on PVC-C Pipe SystemsPhysical Properties, Chemical Resistance, InstallationMaterialGeneral InformationPVC-C is a post-chlorinated polyvinyl-chloride that has been in use in manyand varied industrial applications since1958. PVC-C is in many ways similar toPVC-U due to their similarity in chemica
19、lstructure, however PVC-C offers, incomparison to PVC-U, better mechani-cal strength characteristics especially athigh temperatures together with a bet-ter chemical resistance. The flame retar-dation performance of PVC-C is alsobetter than of PVC-U.These properties have led to PVC-Cbeing used in man
20、y wide and varyingapplications, not only as piping systemcomponents but also in semifinished pro-duct applications in the chemical andaerospace industries for example.As a pressure piping system PVC-Clends itself to highly corrosive environ-ments where the likes of stainless steeland even GRP have r

It offers a wide ranging chemicalresistance against many aggressivemediums at high temperatures and hi

26、sticsthat they act as an insulator. PVC-C is noexception.PVC-C has a thermal conductivity of0.2 W/mC. Steel is approximately250 W/mC. This obviously gives PVC-C many inherent advantages with re-gard to energy efficiency and insulationrequirements.5GEORG FISCHER Physical PropertiesGeorge Fischers PVC
27、-C Piping Systemfulfills internationally recognized stan-dards whereby the vicat point (softeningpoint) of the pipe raw material lies over110C and for the fittings over 103C.These values lead to a restriction on amaximum working temperature of 80Cfor pressure piping systems. GeorgeFischer recommends
28、 a working tempe-rature range of 0C to 80C for PVC-C,whereby the physical advantages of thematerial become most apparent attemperatures between +40C and+80C. All components sold by GeorgeFischer, including the joint, have beendesigned for a life span of 25 years witha safety factor of 2.5.The system
29、 has been designed based onpipe series 6.25 or SDR 13.5 to ISO4065. PN 16 to DIN 8079.Another excellent physical characteristicof PVC-C is its very smooth internal sur-face which not only reduces pressurelosses to a minimum but also offers verylow bacterial growth possibilities andthus a high level
30、of cleanliness.See pictures below which show the sur-face roughness of PVC-C pipe in com-parison with standard stainless steel.Burning CharacteristicsPVC-C is not self-burning. PVC-C re-leases very little energy itself (i. e. it hasa very low heat of combustion) and istherefore classified as non-com
31、bustible.To DIN 4102 part 2 PVC-C is classifiedunder section B1, i. e. non-burning.ColourRAL 7038 aqate greyElectrical PropertiesPVC-C is, like all standard thermo-plastics, non-conducting. This meansthat PVC-C systems incur no electrolyticcorrosion. On the other hand the non-conducting properties m
32、ust be takeninto account as electrostatic charge canbuild up on the pipe. Please take specialcare in environments where explosivegases may exist. Various methods existto avoid the build-up of static charge onplastic pipes, please consult your localGeorge Fischer representative for advice.WeatheringP
33、VC-C can resist prolonged exposure tosunlight, wind and rain. However PVC-Cwill loose some of its impact resistanceunder exposure to UV light and there-fore painting the pipework (with solventfree paint) or protecting it in some otherway from direct exposure to UV light isbeneficial.LimitationsThe f
34、ollowing limitations of PVC-Cshould be observed: use with gases should be checked asgas installations often suffer pressuresurges PVC-C cannot be used with most or-ganic solvents, chlorinated or aroma-tic hydrocarbons, esters and ketones prior testing is recommended whenused with oils, lacquers and
