IS 15659 : Part 1 : 2006 Petroleum and Natural Gas Industries - External Coatings for Burried or Submerged Pipelines Used in Pipeline Transportation of Gas and Liquid Hydrocarbons - Part 1 : Polyolefin Coatings (3 Layer PE and 3 Layer PP)

ICS 25.220.99;75.200 MTD 24
Reaffirmed 2021

1 Scope

This standard (Part 1) specifies requirements of plantapplied external three layer extruded polyethylene andpolypropylene based coatings for corrosion protectionof welded and seamless steel pipes for pipelinetransportation of gas and liquid hydrocarbons in thepetroleum and natural gas industries. The appliedcoating fulfilling the requirements of this part ofstandard is considered suitable for the service,handling, storage, construction and operationconditions described in 9.

NOTE - Coated pipes in accordance with this part of standardare considered suitable to further protection by means ofcathodic protection.
