Petroleum, petrochemical and natural gas industries - External corrosion protection of risers by coatings and linings - Part 1: Elastomeric coating systems-polychloroprene or EPDM (ISO 18797-1:2016)

ISO 18797-1:2016 specifies the minimum requirements for materials selection, surface preparation, application, inspection, testing, qualification and acceptance criteria of external coating for steel risers pipes used in the splash zone, their field joints and clamps/guides, using an elastomeric protective coating based on polychloroprene, EPDM or equivalent. This is applicable for new construction and repair of applied pipes before installation. Maintenance requirements and field repairs are covered in ISO 18797-2.
ISO 18797-1:2016 also specifies the requirements for transportation, handling and storage of riser pipes before and after surface preparation and coating application.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

Introduction

This document is based on GSO 2273. This document defines the minimum technical requirements

for the external corrosion protection of risers by coatings and linings based on elastomeric coating

systems-polychloroprene, EPDM or equivalent elastomeric coatings that are employed in the oil and

gas industry and provides technical guidance for developing local standards and specifications in

order to ensure compliance in coating and lining material selection and performance with contract

requirements.

Users of this document need to be aware that further or differing requirements can be needed for

individual applications. This document is not limiting the contractor and/or manufacturer from

proposing or company from accepting alternative engineering solutions for the individual application.

This can be particularly applicable where there is innovative or developing technology. Where an

alternative is proposed, the specification issuer needs to identify any deviations from this document

and provide details.

This document does not incorporate any form of passive fireproofing requirements or any related

compatibility issues. Any requirements with regards to passive fireproofing are to be addressed

separately.
