| More Info. | <ul><li><b>Material</b><br>PVC Clear piping is produced from a rigid, virgin Polyvinyl Chloride (PVC) compound with a Cell Classification of 12454 per ASTM D1784. This material enables the clear piping to safely carry a maximum service temperature of 140°F when appropriate temperature/pressure de-rating factors are applied. In addition to exhibiting desirable physical properties and optimum transparency, this material complies with the provisions of Title 21 of the United States FDA Code of Federal Regulations, and is safe for use in food contact applications.<br>Clear PVC pipe provides the same reliable chemical resistance properties that PVC piping has demonstrated over the years. In general, it is resistant to most acids, bases, salts and oxidants. Detailed chemical resistance data is available and should be referenced for proper material selection. Since this material is a nonconductor, it is not subject to electrolytic or galvanic corrosion.<br>This material is compatible with standard PVC pipe, fittings, valves, and flush thread screens and casings, and can be incorporated into existing PVC systems via the solvent cement joining process, or threaded together using ASTM F-480 threads. In addition to a full line of clear fittings for most applications, an endless array of standard PVC components and accessories is readily available.<li><b>Product Ratings</b><br>Clear PVC pipe is manufactured in IPS sizes to Schedule 40 dimensions in 1/4" to 8" diameters. This provides sufficient wall thickness for most pressure applications without jeopardizing clarity. As a rigid PVC piping, clear PVC maintains its integrity in harsh Environments. It is suitable for use in industrial, food service, and environ mental applications<br>including the visual inspection of wells. The use of visually clear casing for well inspection is protected by U.S. Patent # 5,123,492 and other international patents. Flush thread piping is non- pressure rated. Refer to the table below for dimensions, tolerances and pressure ratings of non- threaded pipes.<li><b>De-rating Factor</b><br>These temperature de-rating factors are to be multiplied by the pressure ratings listed to determine the maximum pressure rating of the system at elevated temperatures.</p> <table border="0" cellpadding="0" cellspacing="0" width="100%" class="asm_html_tab"> <tr> <td><strong>Operating Temp.
