• 75.200 Petroleum products and natural gas handling equipment

This document specifies the basic requirements regarding design, geometric dimensions, materials, manufacturing procedures, technical requirements, inspection methods, non-destructive testing (NDT), marking, package and storage for corrosion resistant alloy (CRA) clad bends for use in pipeline transportation systems for the petroleum and natural gas industries.

This document is applicable to CRA clad bends for use in transportation or process pipelines transporting corrosive media-containing single-phase or multi-phase fluid such as oil, gas and water for the petroleum and natural gas industries. It can also be used as reference in other fields.

Two technical delivery conditions classes for clad bends are designated. Class B provides a standard quality level for clad bends and Class S provides technical requirements for sour-service conditions. It is the responsibility of the purchaser to specify the appropriated class, based upon the intended use and design requirements.
