AWWA C220-17 pdf download.Stainless-Steel Pipe, 1/2 In. (13 mm) and Larger
Sec.1.1 Scope
AWWA C220-17 pertains to stainless steel pipe that is seamless, longitudinal- seam, or spiral-seam welded; 1/2 in. (13 mm) in nominal diameter and larger; and intended for the transmission and distribution of potable water, wastewater, and reclaimed water, and for use in other water supply system facilities.
Sec.1.2 Purpose
The purpose of this standard is to provide the minimum requirements for stainless stcel pipe,1/2 in. (13 mm) and larger, including materials and quality of work, fabrication of pipe, specials and fttings, testing and inspection, and marking requirements.
Sec. 1.3 Application
This standard can be referenced in documents for purchasing and receiving, as well as serving as a guide for manufacturing, stainless-steel pipe, % in. (13 mm) and larger. The stipulations of this standard ap apply when this document has been referenced and then only to stainless steel pipe, 1/2 in. (13 mm) and larger.
The selection of materials is critical for potable water, wastewater, and reclaimed water service and distribution piping in locations where there is likeli- hood the pipe will be exposed to significant concentrations of pollutants composed of low. molecular-weight petroleum products or organic solvents or their vapors. Documented research has shown that pipe materials (such as polyethylene and . polyvinyl chloride) and clastomers, such as those used in jointing gaskets and pack- ing glands, are subject to permeation by low-molecular-weight organic solvents or petroleum products. If a potable water, wastewater, or reclaimed water pipe must pass through such a contaminated arca or an arca subject to contamination,consult with the manufacturer regarding permeation of pipe walls, jointing materi- als, and so on before selecting materials for use in that area.
4.4.1 General requirements. Pipe produced according to one of the cited ASTM standards shall be subject to ANSI/AWWA C220 quality- assurance pro- Ce cedures and in compliance with applicable provisions of AWS D1.6/1.6M. Such pipe shall be manufactured to meet the requirements of ASTM A312/A312M, ASTM A409/A409M, ASTM A358/A358M, ASTM A778/A778M, ASTM A790/ A790M, or ASTM A928/A928M using one of the types listed in Table 1. As an alternative, the pipe shall be fabricated in compliance with Sec. 4.4 and 4.9. Pipe produced in accordance with A778/A778M shall be pickled.AWWA C220-17 pdf download.
