GB/T 34903.2-2017Petroleum, petrochemical and natural gas industries -- Non-metallic materials in contact with media related to oil and gas production -- Part 2: Elastomers (English PDF)

Foreword

GB/T 34903 "Non-metallic materials in contact with oil, petrochemical, and natural gas industries and media related to oil and gas production" is divided into the following four section.

--- Part 1. Thermoplastic plastics;

--- Part 2. Elastomers;

--- Part 3. Thermosetting resins;

--- Part 4. Reinforcing fibres.

This part is part 2 of GB/T 34903.

This section was drafted in accordance with the rules given in GB/T 1.1-2009.

This section uses the translation method equivalent to the use of ISO 23936-2:2011 "oil, petrochemical and natural gas industries and oil and gas exploration related media access.

Touched non-metallic materials - Part 2. Elastomers".

1 Scope

GB/T 34903 provides general principles for the selection and evaluation of non-metallic materials used in petroleum and natural gas production facilities.

Requirements, Recommended Practices, and Product Quality Assurance Guidelines. Failure of equipment caused by failure of non-metallic materials will result in public health, personal safety and Environmental risk. This standard helps to avoid such costly corrosion damage to the equipment. This standard supplements and does not replace the design of equipment.

Materials and technical requirements that are already in the standard or legal specification.

This part of GB/T 34903 specifies the assessment requirements and procedures for elastomer materials used in oil and gas extraction equipment.
