.1 General Provisions
1.01 This standard is formulated to facilitate production management, maintenance and overhaul, reduce misoperation and promote safe production by coloring ground pipelines and equipment in oil and gas gathering, oil and gas processing and long-distance pipeline projects in oil and gas fields. 1.0.2 This standard applies to the surface color marking of ground pipelines, various containers, heat exchangers, towers, heating furnaces, pumps, instruments, electrical appliances, structures, etc. in various new, expanded and rebuilt projects of oil and gas fields and long-distance pipelines. Note: 1 Containers include separators, transportation containers, etc.; buildings refer to steel pipe supports, tongues, ladders, railings, frames, 1.0.3 The surface color of ground pipelines and equipment in oil and gas gathering and processing projects shall comply with the current national regulations in addition to the implementation of this standard. According to the relevant standards, 1.0.4 No. 1 Standard
GB723-1987 Basic Identification Colors and Identification Symbols for Industrial Pipelines GB6527.1-1986 Safety Color Card
GB6527.2-1986 Safety Guidelines 2 General Provisions
The colors of the exterior surfaces of pipelines, containers, heat exchangers, towers, electrical appliances and meters that do not require insulation in oil and gas field stations (plants) shall comply with the provisions of Chapter 3 and Appendix A of this standard.
Insulated pipelines can retain the original color of the protective layer, but should be painted with the specified signs and color rings, or they can be painted with the colors specified in Article 3.0.1. 2.0.3 Insulated containers can retain the original color of the protective layer or be painted according to the provisions of Table 3.0.2. 2.0.4 The surfaces of Christmas trees, pumping units, motors and various valves can retain the factory colors of the manufacturer.
2.0.5 The surface color of flowmeters, compressors, and pumps can be consistent with the color of the pipelines of the transported media, or keep the color of the manufacturer. 2.0.6 Stainless steel containers, stainless steel pipelines, electroplated pipelines, and surface galvanized pipelines can keep the original color of the raw materials or the original color of the protective layer. 2.0.7 In addition to being painted in accordance with regulations, pressure pipelines should also be painted with color rings in accordance with regulations. 3.0.1
