This standard presents recommended practices for the control of internal corrosion in steel pipelines and piping systems used to gather, transport, or distribute crude oil, petroleum products, or gas. It is meant to serve as a guide for establishing minimum requirements for control of internal corrosion in crude oil gathering and flow lines, crude oil transmission, hydrocarbon products, gas gathering and flow lines, gas transmission, and gas distribution. This standard is maintained by Task Group 038.This standard serves as a guide for establishing minimum requirements for management of internal corrosion in the following systems: (a) Crude oil gathering and flow lines (b) Crude oil transmission (c) Hydrocarbon products (d) Gas gathering and flow lines (e) Gas transmission (f) Gas distribution (g) Storage systems (h) Produced water lines (i) Injection water lines
