Painting of chemical equipment foundations

There’s no strict requirement for this; the key is to keep it consistent. Attached is a list of the requirements from our company. Part 1: On-site labeling of equipment. I. Scope of equipment that requires standardized labeling: (1) Class A equipment – oil and gas production equipment such as raw material gas compression units, stabilization compression units, refrigeration compression units, expansion compression units, gas injection compression units, gas transmission compression units, and heat transfer oil furnaces; as well as construction equipment such as workover rigs, fracturing units, nitrogen production systems, liquid nitrogen pump trucks, and coiled tubing trucks. (II) Class B equipment: oil pumps, water injection pumps, heat exchangers, radiators, filters, boilers (steam, hot water), heating furnaces, pressure vessels, and the machinery and pumps associated with various supporting systems. (III) Class C equipment: instruments, meters, and other auxiliary equipment. II. Standardize and unify equipment identification (1) For Category A equipment, all gas feed, stabilization, gas injection, and gas transmission compression units shall be colored red. The equipment management labels shall be vertical and golden in color; the information on these labels should include at least the equipment category, name, specifications and model, manufacturer, date of commissioning, as well as the main technical parameters of the equipment ； The instrument air system uniformly uses blue ； Refrigeration compressors and expansion compressors are in dark blue ； The surface of the heat transfer oil furnace is silver-white in color ； The main body of the workover rig is entirely red, while accessories such as the derrick and drill floor are uniformly white ； Key equipment such as fracturing units, nitrogen production systems, liquid nitrogen pump trucks, and coiled tubing trucks maintains its original factory color. (II) In Category B equipment, the motors are uniformly gray ； The pumping units are uniformly orange-yellow, with the words “China National Petroleum” and its logo printed in the center of the beam ； Pumps in the water injection system are uniformly colored green, pulleys are red, while other pumps are uniformly colored blue ； Fire pump and motor are red ； Boilers and pressure vessels equipped with insulation are made of silver-white metal sheet; those without insulation generally match the color of the associated pipelines (for example, natural gas containers are yellow, while instrument air containers are sky blue). Auxiliary containers match the color of the main equipment, and larger heating devices can retain their original factory color. Both types of equipment are equipped with special equipment identification tags, which are uniformly yellow in color ； Gantry cranes and overhead cranes in lifting equipment remain in their original factory colors ； There are no uniform requirements for elevators ； On-site motor vehicles and recreational facilities shall maintain their original factory colors ； Heating furnaces and atmospheric pressure boilers for oil fields are uniformly silver-gray (except those with insulation). Class B devices are uniformly equipped with silver device management labels on their bodies. (III) In Category C equipment, instruments and other accessories may retain their original factory color. The high-pressure valves and safety valves designed for use with the equipment are uniformly colored red, while other types of valves are colored yellow, green, or gray depending on the medium they handle. (IV) Special-purpose vehicles, cranes, trucks, construction machinery, and machining equipment may retain their original production colors, but the color markings of devices of the same specification and model must be uniform. For other special equipment and dedicated equipment that do not involve the specified markings, their original production color shall be retained. (5) The identification colors for above-ground pipelines, tanks (for oil, water, gas), and towers for different media such as light hydrocarbon plants, gas injection systems, gas transmission systems, water injection systems, and oil and gas sales operations shall be in accordance with the CNPC SY0043-96 standard. III. Relevant Requirements (1) In on-site management, it is necessary to properly distinguish between Type A and Type B equipment. The identification tags for equipment should be in either gold or silver color, with their size to be determined based on the actual size of the equipment itself. (II) The labels on pressure-containing equipment among Category B devices must be clearly distinguishable; the text on the labels of pressure-containing equipment is in red to facilitate identification and safe operation, while the text on the labels of other devices is in black. (III) To achieve better uniformity in identification, in future equipment bidding and selection processes, the color requirements for the equipment shall be consistent with the identification colors specified in these regulations. (IV) The colors and markings of the equipment not specified in this plan shall remain as they are.
