1.0 SCOPE The specification covers the corrosion survey including measurement of soil resistivity, chemical analysis of soil/ water and other cathodic protection related data collection along right of way of the pipelines. 2.0 CODES AND STANDARDS 3.0 GENERAL Equipment and measurement techniques shall unless otherwise specified, conform to the requirement of following latest applicable standards:- BIS Specifications BS Specifications and Codes of Practice NACE Publications This specification defines the basic guidelines for carrying out the corrosion survey. Contractor shall be responsible for providing necessary data interpretation based on corrosion survey measurement which is intended to form a basis for design of cathodic protection system for the pipeline to be burried along ROW. 4.0 SOIL RESISTIVITY SURVEY 4.1 Unless otherwise specified the soil resistivity measurements shall be carried out at intervals of approximately 500 mtr. along the ROW. Where soil resistivity is less than 100 ohm mtr and two successive readings differ by more than 2:1 then additional soil resistivity readings in between the two locations shall be taken. 4.2 To carryout the soil resistivity measurement Wenner’s 4 pin method or approved equal shall be used. The depth of resistivity measurement shall be around the burial depth of the pipeline or 1.5 mtr approximately. At locations where multi layer soil with large variation in resistivity/ corrosiveness is expected and/ or locations specifically advised by Owner or his representative resistivity measurements at additional depth of upto 2.5 mtr (approx.) or more shall be taken. In general the resistivity of soil which shall be surrounding the pipe shall D:\old data\FATEH\MP Region\Kailaras\Tender RFQ\TCP&PCP\Specification - Corrosion Survey - 016C.doc Page 1 of 5
