1 GuideSingle Wall Piping Double Wall Piping Gas & Air Handling Systems Materials System Design Installation DESIGNGUIDEASAHI/AMERICA, , MassachusettsDisclaimerAsahi/America, Inc. provides this Guide to assist engineers in the Design ofsystems, installers in the installation and owners in the operation. This guideis designed to provide the best possible recommendations known at thetime of printing. Each and every type of piping system is different and no onerecommendation can cover all conditions. This Guide is made available toassist in the Design and installation, but in no way should be construed as awritten recommendation on any system.

2 Each system should be individuallydesigned and installed based on the responsibility and decisions of thepurchaser. This Guide is not a substitute for contacting Asahi/America forspecific recommendations on a system. In addition, Asahi/America is notresponsible for items not appearing in the Guide or recommendations thatmay have changed after the printing of this Guide . It is recommended in eachcase to consult Asahi/America for specific recommendations on each 2013 Asahi/America, Inc. All rights reserved. Printed in THE COMPANYA sahi/America, Inc. a wholly-owned subsidiary of Asahi Organic Chemical, pioneered the market for thermoplastic valves and piping in the United States and Latin America, during a time when there was no viable alternative to metal for piping systems.

3 Asahi/America began by promoting valves from a company known as Asahi Organic Chemical Industry Co., Ltd. (AOC) and piping through AGRU GmbH in Austria. Through distributor and end user education and acceptance, the use of thermoplastics has grown. Asahi/America now manufactures and distributes thermoplastic products including valves, actuators, single and double wall piping systems and specialty components throughout the US and Latin is a diversified ISO9001:2015 certified manufacturer and supplier of corrosion resistant fluid flow products. Headquartered in Lawrence, Massachusetts, where we operate a 220,000 square foot manufacturing and warehouse facility, Asahi/America supports all of our products with a comprehensive selection of in-depth technical documents and product catalogs.

4 To access any of Asahi/America s technical documentation, testing information, or product catalogs, visit the company s web site at or contact Customer Service at makes Asahi/America special is our ability to provide solutions for corrosive or high purity fluid handling systems individualized to meet virtually any customer s need. The Asahi/America technical staff is able to provide superior knowledge of products, applications and installations. Asahi/America is poised to support your next project with the assistance of our large distribution is proud to present this Engineering Design Guide to you. This publication represents over 40 years of experience, talent, and Engineering expertise.

5 It is intended to aid in the process of Engineering , specification, and Design of industrial plastic piping systems using the family of Asahi plastic piping systems. We encourage you to use it often and call upon our staff of piping and valve engineers if there is something we have neglected to cover.

Each material has unique and specific mechanical properties. These diverse properties allow plastic to become the preferred system for many applications that range from the transport of aggressive chemicals to the distribution of ultra pure water. Because each material has its own unique properties, understanding them becomes vital to the successful Design , installation, and operation of a system.

8 Asahi/America is proud to present this Design Guide to assist Design engineers and system installers with the proper Engineering , layout, and installation of plastic systems. Asahi/America is a pioneer in the manufacture and distribution of plastic systems in the United States. Since the 1970 s, we have dedicated ourselves to assisting our customers in achieving the maximum benefits plastic systems offer. Designing a system made of thermoplastic materials differs considerably from that of metallic materials. No one understands this as well as Asahi/America s sales and technical staff. Our trained staff is available to assist with all aspects of plastic piping systems.

9 The information contained herein is designed to minimize the efforts of engineers, designers, contractors, and research professionals in sizing and selecting all aspects of fluid Plastic BenefitFor pipe, fittings, and valves, thermoplastic materials offer superior corrosion resistance, lighter weight, simple installation, and a more cost-effective ResistancePlastics are non-conductive and are therefore immune to galvanic or electrolytic erosion. Because plastics are corrosion resistant, pipe can be buried in acidic, alkaline, wet or dry soils without requiring a protective coating. In addition, cathodic protection devices are not CompatibilityImpervious to many chemicals, thermoplastics are gaining an ever-increasing acceptance and preference in a large variety of applications.

10 Additionally, the variety of materials available allow a wide range of chemical solutions to be handled successfully with plastic ConductanceAll plastic piping materials have low thermal conductance properties. This feature maintains more uniform temperatures when transporting fluids in plastic AINTRODUCTIONPLASTICS IN FLUID HANDLING than in metal piping. Low thermal conductivity of the plastic piping wall may eliminate or greatly reduce the need for pipe insulation to control Friction LossBecause the interior surface of plastic piping is generally very smooth, less power may be required to transmit fluids compared to other piping systems.
