PipingSystems Design Installation,Technical Information. Introduction, The physical properties and chemical compatibility data provided by most plastic pipe manufacturers is generally reproduced. form data supplied by the Raw Material Producer This data is obtained by testing specimens which are ideally produced and. thus lack inherent stresses or orientation Understandably specimens produced in this manner will provide generally better test. The properties given on the following pages have been measured by testing extruded panels or coupons The object being to. provide data more indicative of what will normally be achieved by these materials when produced as pipe or extruded sheet The. information indicates average values for 4mm thick extruded coupons unless stated otherwise. The data provided is in no way a guarantee of the suitability of the material for any application It is not possible to apply our test. results automatically to finished components For this reason the suitability of our materials for a specific application must be. rechecked by the user,Materials Information,Material Type Polypropylene PP. SIMTECH S SR Series Polypropylene piping as produced by SIMONA is extruded from A Group 1 Class 1 Grade 0 Polypropyl. ene Homopolymer material per ASTM D4101 Federal Specifications L P 39413 and Military Spec Mil P 461096 PP material. to be heat stabilized UV stabilized and pigmented to RAL 7032 Temperature stabilizers are added to provide the material with. enhanced resistance to aggressive media at elevated temperatures. Stress Relieved, SIMTECH S SR Series pipe is Stress Relieved through a post extrusion annealing process This process allows the pipe to perform. to its fullest potential SR Series pipe possess higher impact strength higher quick burst pressures improved resistance to oxidizing. acids and longer service life expectancy compared to pipe that is not subject to a post extrusion annealing process. Chemical Resistance, SR Series Polypropylene is especially suitable for handling Dilute Acids Alkalies many strong acids and organic solvents.
Polypropylene should not be used to convey Halogens Halogenated Hydrocarbons Aromatics or highly concentrated Oxidizing. Acids More detailed information is available in our Chemical Resistance Guide. Temperature Range, SR Series PP is suitable for application within an operating range from 32 F to 212 F. Phone 877 777 2467 Fax 215 547 9129,www SimtechUSA com.

Radiation Resistance, Both Polypropylene and PVDF possess resistance to high energy radiation However as can be seen in Table 3 PVDF is far supe. rior to PP, With regard to the order of magnitude the lethal dose for human beings is approximately 0 0006 Mrad From this it can be con. cluded PP and PVDF can be used in rooms in which humans are allowed to remain constantly.

Material Properties,Weather Resistance, Nearly all thermoplastics used for piping require stabilizers to reduce the effects of sunlight and oxygen PVDF is the major.
exception in that it suffers no significant degradation when used outdoors All other materials are generally compounded with UV. stabilizers and anti oxidants to retard the rate of degradation While this procedure is effective it does not totally eliminate the. phenomena To maximize the service life of a system it can be covered coated wrapped or painted SRvf PVDF does not require. protection,Moisture Absorption, SR Series PP and SRvf Series PVDF are water repellent There is no swelling or dimensional change A slight weight gain may be. found in testing due merely to traces of moisture on the surface. Resistance To Rodents and Micro Organisms, Rodents endeavor to sharpen their teeth by gnawing hard objects This applies to timber soft metals and plastics which neither in. terms of taste nor in terms of odor encourage consumption of the material However because the smooth surface of polypropyl. ene and PVDF do not provide enough grip for teeth there are virtually no attempts by rodents to gnaw at pipe or the surface of flat. The raw material is not a nutrient for micro organisms such as bacteria fungi or spores and therefore is not attacked by them This. also applies in respect to Sulfate Reducing Bacteria SRB s which can result in metallic piping being pitted to the point of failure. Electrical Conductivity, The materials PP and PVDF like all other plastics form part of the group of electrically insulating materials This includes all ma. terials which have an impedance in excess of 106 Ohm x cm The stated materials have an impedance of the order of approx 1015. ohm x cm In addition the surface resistance should be noted If the value of 109 Ohms is exceeded then the material should be. categorized as electrostatically chargeable, In connection with the construction of plastic pipe systems electrostatic charges have to be taken into consideration If the media. being transported are not electrically conductive or if the pipes are installed in areas which are subject to explosion hazard the. transport of gases or liquids which can ignite is only free from risk if a closed system is used In addition it is possible to reduce. the risk of charging by reduced conveying speed, Explosive atmospheres in areas in which plastic pipe is to be installed can be avoided by careful ventilation or by ionizing the.
air so that the plastic does not become electrostatically charged Since electrostatic charges are rarely produced when the relative. humidity is in excess of 65 an increase in the humidity can provide another solution to the problem. It is fundamentally possible to make electrically nonconducting plastics into plastics that are electrically conductive Manufacture. of certain pipe made from electrically conductive PP or PVDF is possible but require minimum order quantities for both materi. als We look forward to your inquiry in the event of a need. Pressure Rating and Service Life, Pressure Rating for plastic piping is normally expressed based on a 20 C 68 F continuous operating temperature i e 150 psi at. approximately 68 F Higher continuous temperature results in a lower pressure rating in accordance with procedures outlined by. ASTM D 2837 and the Plastic Pipe Institute Division of SPI The expressed pressure rating of plastic piping represents 50 of the. pipes burst pressure after 100 000 hours or 11 4 years of continuous service It is then assumed that the theoretical time to failure. is 50 years, SR Series Polypropylene piping is offered as SR150 SR90 and SR45 indicating 150 psi 90 psi and 45 psi respectively These rat. ings were used to avoid confusion in the marketplace We chose to indicate pressure ratings that matched in the industry norm. However if you will examine Table 5 you will see that we greatly exceed the Industry Standards i e SR 150 at 68 F at 50 years. service life can actually be pressurized to 180 psi continuously and still provide a safety factor of 1 7 1 for 50 years.
