Standard for Identifying Facilities and Equipment in Oil Depots: This standard is formulated to further standardize the management of facilities and equipment in oil depots, improve operability, and ensure that the colors and numbering of such facilities and equipment within the system are standardized and unified. I. Overview 1. Terminology Explanation Equipment and facilities: In this standard, equipment and facilities refer to motors, pumps, storage tanks, pipelines, valves, warning signs, and other devices that are closely related to the production and safety of oil depots. Color codes: A general term for the color rings, strips, flow indicators, logos, and numbers that should be applied to the entire or part of facilities and equipment. 2. Color specifications: The 7 colors used in this standard are as follows: Off-white (K5) as the base color; Red (M100 Y100); Gray (K75); Dark gray (K90); Yellow (Y100); Green (C100 Y100); Black (K100).
II. Application of colors: Colors specific to different types of oil: Gasoline – red; Diesel – gray; Kerosene – yellow; Lubricants – dark gray. General rules: The base color (or primary color) is off-white for all equipment and facilities used for oil transfer, delivery, tank cleaning, and storage within oil depots, unless otherwise specified. This includes oil storage tanks, outdoor oil pipelines, trestles, vacuum system equipment, and power distribution protection systems. Color codes for storage and transportation facilities and equipment: The color codes for facilities and equipment used for storing and transporting gasoline, diesel, and kerosene are the same as those specific to each type of fuel. This includes color rings on oil tanks, valve handles, color rings and flow indicators on outdoor oil pipelines, as well as electrical control switches and buttons in oil pump rooms ； The overall color of the oil transfer pipelines in the oil pump room matches that of the corresponding oil type; the flow direction markers are milky white, without any colored rings. Lubricating oil system – the color rings on the oil tanks and the valve handles are dark gray ； ——The oil pipeline has no color rings or flow direction markers. Pipelines with insulation outdoors are entirely in the color of the insulation material, while those without insulation are entirely milky white ； The pipelines in the pump room are uniformly dark gray. ——Valves and electrical control switches on the same pipeline should be equipped with uniform lubricant type labels for ease of operation. Color codes for fire protection equipment: The fresh water fire protection system and the standby pump system are labeled green; this includes fresh water pumps, standby pumps, fresh water pipelines, standby pump pipelines, valve handles, fire hydrants, etc. Fire foam system—red, including foam pumps, pipelines, valve handwheels, foam nozzles, foam tanks, foam generators, etc. Other fire-fighting equipment – red, including fire sand boxes, buckets, the main body of mobile fire pumps, etc. Special note: Equipment that retains its original color includes oil transfer pumps, motors, dip pipes, the above-ground portion of buried cables, fire telephones, and distribution cabinets. Valves—All valve bodies (or valve casings) used in oil depots shall be black in color ； The protruding marks for specifications and nominal pressure are in red ； The direction arrow of the handwheel switch is milky white. Indoor heating pipelines – indoor heating pipes and radiators are in silver-gray (silver powder) color. Warning signs – the signs intended to prevent electric shock in the vicinity of power distribution systems and equipment, as well as the \"Do not close\" signs, should all have red text on a white background. III. Specifications for color coding: For oil storage tanks, vertical oil tanks – Position of painting: The center line of the color coding ring is determined at 2/3 of the total height of the tank wall; the outer boundaries of this ring are defined by extending half the width of the ring upward and downward, and painting is applied along the entire perimeter of the tank ； Width—6% of the total height of the tank wall. Logo: Dimension ratio — The ratio of the logo’s width to its height is 105:110; the width of the logo is 18% of the total height of the tank wall, and its height is determined based on this dimension ratio ； Spraying position—Spray above the color code ring, with the bottom edge being 2% of the total height of the tank wall from the top edge of the color code ring. Orientation—towards the main road. Tank number: Format ① is company name, followed by a space, then product type—tank sequence number—tank capacity. ②The company name uses the uppercase character “HBSY”, which is the first letter of the pinyin for “Hebei Petroleum”” ； ③For oil products, the storage medium is represented by the uppercase first letter of its Pinyin, such as gasoline – Q, diesel – C ； ④Tank number: from 01 to 99 (these are the tank numbers for this oil depot) ； ⑤The unit for oil tank capacity is m3 ； ⑥The “horizontal line” connecting letters is specified as one cell distance ； ⑦The above fonts are in bold type and Arabic numerals, and are printed at the specified location below the color code ring according to the size requirements for each character. The size of each character is determined based on the height of the oil tank (see Table 1). Example: HBSY Q—01—1000 refers to Hebei Petroleum, gasoline, tank No. 01, with a capacity of 1000 m3. Table 1: Standard Parameters for Tank Height. Unit: mm. Parameters include: color band width, logo, tank number, distance from the mark, aspect ratio (width:height), width, character aspect ratio (width:height), character width, character spacing, space width, horizontal line aspect ratio (width:height), and horizontal line width. Values: 6%A, 105:110; 15%A, 9:10; 3.6%A, 6.5‰A; 2%A, 2:1; 1.5%A, 2%A. Note: ① The values in the table are based on the total height A of the tank wall ； ②““The distance from the mark” refers to the distance from the bottom or top edge of the logo or tank identifier to the upper or lower edge of the color mark ring. ③ When the height differences among tanks with the same capacity within the same tank group are within 1 meter, the average height of these tanks can be used as the total height A to determine other parameters ； Again, using the oil tank with the highest height as a reference, 2/3 of its height is taken as the common centerline position for the color marking rings on these oil tanks. Horizontal oil tank – Color ring: Location – The center line of the color marker ring is determined at 1/2 of the total height of the oil tank; paint is applied within the specified width, all around the perimeter of the oil tank ； Width—refer to Table 1. Logo: Location – Painted in the center below the color ring at one end of the tank head; Size – Refer to Table 1 ； Direction: Towards the main road. Tank number: Refer to the vertical oil tank ； Location — Paint at the center, above the color-coded ring at one end of the tank head ； Dimensions—Refer to Table 1 ； Direction — Towards the main road. The signs on the canopies of the fueling kiosks follow the guidelines specified in the latest version of \"Sinopec Corporation Gas Station Identity Standards (Canopies)\“. Oil pipelines, outdoor: The painted color for outdoor above-ground oil pipelines is milky white ； Material – Industrial paint; Scope – Entire pipeline ； Color coding: On outdoor above-ground oil pipelines, 6 cm wide color rings are applied every 30 meters along the straight sections, at each turn, at each point where the pipeline passes through a wall, and at each branch point, to indicate the type of oil. Inside the pump room: Color coding – Gasoline (Q) – Red ； Diesel (C) – Gray ； Kerosene (M) – Yellow ； Lubricating oil (H) – green. Scope: The entire pipeline. Flow indicator: Spraying location: Above the outdoor above-ground oil pipeline – the tail of the arrow is 6 cm away from the center line of the color ring, and its color matches that of the color ring on the same pipeline ； Oil transfer pipelines in the pump room — directly above the pipelines, all in milky white color. Style specifications (taking red as an example): Single arrow indicates direction: Straight segment—2cm×21cm ； Triangle head—4cm×6cm; double arrows indicate direction: straight line segment—2cm×15cm ； Triangle head—4cm×6cm; single arrow turning direction: broken line segment—2cm×7.5cm, 2cm×9.5cm ； Triangular head—4cm×6cm, 3000m3 vertical gasoline tank: Example of color coding specifications: (Tank height: 12 meters, diameter: 18.8 meters). Tank: Color—milky white; Material—industrial paint; Application area—the entire tank. Color ring: Gasoline – red. The width of the color ring is 720 mm; the center line of the ring is determined at 2/3 of the height from the bottom of the tank, with the outer edges extending 360 mm upward and downward for painting. Logo: Located 240 mm above the color ring, 2160 mm wide and 2262 mm high, facing the main road. Number: Located directly below the logo, 240 mm from the bottom edge of the color ring; the specific specifications are as given in Table 1, and the font used is SimHei.
