This document applies to the installation, fabrication, installation, maintenance, and management of route markers for onshore and nearshore oil and gas pipelines. The installation, fabrication, installation, maintenance, and management of route markers for other pipelines shall refer to this document. 2 Normative References The following documents contain provisions which, through reference in this text, constitute indispensable provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies. GB 50251 Code for Design of Gas Transmission Pipeline Engineering GB 50253 Code for Design of Oil Transmission Pipeline Engineering 3 Terms and Definitions For the purposes of this document, the following terms and definitions apply. 3.1 pipeline marker Various marks used to identify the pipeline route. Note: Includes facilities such as mileage posts, test posts, marker stakes, warning signs, communication stakes, and warning tapes. 3.2 mileage post Facility used to mark the distance and location of the pipeline. 3.3 test post Facility used for monitoring and testing parameters such as pipeline cathodic protection. 3.4 marker stake Ground surface marker used to indicate changes in pipeline direction, intersections with surface projects (underground obstructions), management unit boundaries, and pipeline auxiliary facilities. Note: Includes turning point stakes, crossing stakes (rivers, highways, railways, tunnels), intersection stakes (pipeline crossings, cable crossings, power cable crossings), boundary stakes, and facility stakes. 3.5 additional stake Ground surface marker installed at specific intervals between two adjacent pipeline markers to confirm the pipeline alignment. 3.6 communication stake Ground surface marker used to indicate the installation location and alignment of communication cables. 3.7 warning sign Marker used to indicate the pipeline location, warn of potential dangers, and provide contact information. 3.8 warning belt Strip-shaped marker installed above buried pipelines to prevent damage to the pipeline by third-party construction. 4 General Principles and Requirements 4.1 For the same pipeline, the material, appearance dimensions, specifications, form, color, and content of markers should be consistent. Installation shall be reliable and maintenance convenient to facilitate management. Gas pipeline installation shall comply with GB 50251, and oil pipeline installation shall comply with GB 50253. 4.2 Markers installed along the pipeline route shall be sturdy, durable, aesthetically pleasing, with standardized content and clear markings. 4.3 Pipeline route markers shall be installed directly above the pipeline centerline. When installation directly above is not possible, the offset should be within 1m on either side of the pipeline centerline. Under particularly constrained conditions, the offset for warning sign installation should be within 2m on either side of the pipeline centerline. 4.4 Marker stake installation should minimize impact on land use and should preferably be located on ridges, roadsides, or wasteland. 4.5 Mileage post numbering should preferably be unified sequentially from the start point to the end point for each pipeline. 4.6 Nearshore pipelines should be equipped with offshore markers where appropriate. 4.7 Except for turning point stakes, when multiple pipeline markers need to be installed at the same location, preferably no more than 2 markers should be installed. 4.8 For warning signs installed in areas inhabited by ethnic minorities, the marker content should include warning text in the local ethnic language where appropriate. 4.9 Marker stakes may be installed as needed at locations where there are changes in pipe diameter, wall thickness, or coating, as well as for nearshore pipelines. 4.10 Rerouted pipeline sections shall be numbered sequentially separately; the numbers for other pipeline sections shall remain unchanged. 4.11 Mileage posts specifically for the rerouted section shall be installed at the start and end points of the rerouted pipeline section. These reroute mileage posts shall indicate the original pipeline post number, the reroute post number, and the corresponding mileage. 4.12 When pipeline markers are completely replaced, all markers shall be reinstalled entirely. Rerouted pipeline sections shall be included in this process and renumbered to correspond with the actual pipeline mileage. 5 Installation Requirements 5.1 Mileage Post 5.1.1 Mileage posts should preferably also serve as test posts. Unless specially spaced under exceptional circumstances, a mileage post should be installed every kilometer. 5.1.2 Mileage posts shall be installed according to the principle of facilitating inspection and minimizing impact on cultivation. The installation location for mileage marking may be adjusted slightly as convenient nearby. 5.2 Test Post Test posts shall be installed at locations where monitoring or testing of pipeline cathodic protection parameters is required. 5.3 Turning Point Stake For buried pipelines, a turning point stake shall be installed when the horizontal direction change exceeds 5° at a single point. 5.4 Crossing Stake
