Ductile Iron Pipe (cont.) In 1971, ANSI Standards Committee A21, under the sponsorship of AWWA, NEWWA, AGA and ASTM (the Committee responsible for the current revision of ANSI/AWWA C150/A21.50) developed ANSI/AWWA C105/A21.5 - Polyethylene Encasement for Ductile Pipe Systems, which provides details on material and installation and incorporates DIPRA’s 1968 evaluation procedure as an appendix.

PRESSURE CLASS/THICKNESS CLASS 2 Certified to ANSI/NSF 61 Each of the following is a nationally recognized standards organization: American National Standards Institute (ANSI) American Water Works Association (AWWA) American Society for Testing and Materials (ASTM) Underwriters Laboratories (UL)

This standard covers the thickness design of ductile iron pipe complying with the requirements of ANSI/AWWA C151/A21.

标准号 ANSI/AWWA C150-2008 发布 2008年 发布单位 美国国家标准学会 当前最新 ANSI/AWWA C150-2008 适用范围 本标准描述了符合 ANSI/AWWA C151/A21.51《离心铸造水用球墨铸铁管》要求的球墨铸铁管的厚度设计。

This standard describes the thickness design of ductile-iron pipe complying with the requirements of ANSI/AWWA C151/A21.51, Ductile-Iron Pipe, Centrifugally Cast. Sec. 4.1 outlines the design procedure, and Sec. 4.2 gives a design example. Sec. 4.3 explains the basis of design. As opposed to using procedures in Sec. 4.1 or Sec. 4.3, the designer may reference Tables 12 through 14 directly ...

2014年6月8日 · This standard describes the thickness design of ductile-iron pipe complying with the requirements of ANSI*/AWWA C151/A21.51, Ductile-Iron Pipe, Centrifugally Cast, for Water.

SUGGESTED SAMPLE SPECIFICATION FOR DUCTILE IRON PIPE & FITTINGS Ductile iron pipe shall be designed in accordance with the latest revision of ANSI/AWWA C150/A21.50 for a minimum 150 psi rated working pressure plus a 100-psi surge allowance. If anticipated project requirements include greater working or surge pressures, the actual anticipated total pressure should be used. This design standard ...

The design principles and procedures for ductile iron pipe that were included in the ANSI Standard A21.50 (AWWA C150) were verified by trench tests at AMERICAN and tests conducted by various researchers. AMERICAN’s former Technical Director Dr. Ed Sears was instrumental in these developments.
