in 2019, Dongying United Petrochemical Co., Ltd. and its holding Dongying Weilian Chemical Co., Ltd, The newly-built projects Dongying United Petrochemical 2.6 million ton/year heavy oil hydrocracking and supporting engineering project and Dongying Weilian chemical 2million ton/year paraxylene project are particularly eye-catching coatings. As a demonstration project for the transformation and upgrading of petrochemical industry clusters in Shandong Province, the project is a major raw material engineering project for Dongying Petrochemical to develop the downstream aromatic industry. It is also a key step to accelerate the pace of industrial transformation and upgrading and the transformation of old and new kinetic energy, and realize the transformation from "single refining" to "simultaneous development of oil and chemical". Such large-scale petrochemical projects often have huge investment, many facilities, and are in a complex corrosive environment. Some facilities operate at high temperatures of 200 ℃, 400 ℃ or even 600 ℃, which means that in addition to conventional corrosion prevention, it is also necessary to consider the service life of equipment under complex working conditions to ensure that petrochemical devices can maintain excellent operation status at any time after they are put into use. In order to ensure the quality of the project, the owner hopes that the parts of 4.2 steel parts that are often twisted and easy to wear should be heat treated. The warranty period of the anti-corrosion project is 10 years

after some research and analysis, Haihong Laoren, a world-famous coating enterprise from Denmark, decided to accept the challenge. After many technical exchanges with the project owner and the general contractor of the project, and in-depth analysis of needs, it was finally awarded the bid with the advantage of product performance

it is not accidental for Sinopec to choose Haihong old man. In the follow-up cooperation, Haihong old man showed super high skills and services

first, the scheme is scientific and reasonable. According to the operating environment of the device, they carefully created customized coating solutions. For example, coating products with excellent corrosion resistance are provided for conventional equipment and pipe gallery steel structures; For high-temperature equipment, the main product with excellent high-temperature resistance - Silicone high-temperature paint is launched. This product can form a hard coating after curing in the atmospheric environment, and the maximum temperature resistance can reach 600 ℃, which can bring worry free protection to high-temperature equipment

second, there is a rapid response mechanism. During the implementation of the project, the one-year construction period is a severe test for the timely supply capacity of suppliers. To this end, Haihong old man has specially set up a joint business team, including sales, customer service, on-site technical service engineers and logistics, to carry out the full flow from order placing to production arrangement to paint delivery. Different load ranges can be selected according to the parts used or whether they are painted. In case of urgent arrival of the project or delayed arrival due to limited site and other reasons, they give full play to the role of China's production base, and the customer service will uniformly organize and coordinate the production and supply plan, build an agile supply chain, and meet the urgent delivery needs of the project at any time

third, implement lean management. The project has a large scale and complex organizational structure. The interested parties include the project owner, the project general contractor, four project subcontractors and many painting construction teams under the subcontractors. Some coatings are purchased by the general contractor of the project, some by the project owner, and the coating construction team of the corresponding subcontractor is responsible for receiving the goods. Moreover, the demand for petroleum products will be further expanded by their respective unloading, and the delivery locations are also different, which makes the process of each delivery relatively tortuous and complex. In view of these situations, they gave full play to the role of on-site technical service engineers, went deep into the front line, sorted out the receiving process, directly supplied it to the project subcontractor, and simultaneously informed the project owner or the project general contractor, simplifying the on-site delivery communication process and improving work efficiency

fourth, strictly control the technical quality. According to the requirements of the company and the agreement between the two parties, the technical service engineer will be stationed on the site at the beginning of the project, and under the organization of the owner and the general contractor, guide each Subcontractor to improve the coating construction scheme, including: paint product introduction, construction environmental conditions, construction equipment requirements, surface treatment requirements and paint construction precautions

in order to ensure quality, their technical service engineers also went deep into the core of the coating work, strictly controlled the coating construction according to the technical standards, and ensured that the coating was correctly coated and maximized efficiency. For example, guide all subcontractors to measure the wet film during the painting process, so as to better control the film thickness and avoid excessive repair in the later stage; Instruct all subcontractors to apply inorganic zinc rich paint in dry weather and test the curing degree, and take necessary measures to assist the curing of incomplete cured coatings; As all subcontractors carry out paint construction in the open air, bad film formation and additional waste caused by paint loss will be caused in windy weather. The technical service engineer will also timely remind to avoid construction in windy weather; Before the arrival of winter, the technical service engineer will also provide winter construction guidance in advance to avoid paint film defects caused by temperature changes during on-site construction

these measures and practices are deeply recognized by the owner. At present, the United Petrochemical Project is being carried out in an orderly manner according to the construction schedule, and the figure of Haihong old man flashes in the meantime

multi purpose equipment and steel structures for production plants in industrial enterprises. Painting is the last barrier for equipment protection. If the paint type is improperly selected or the construction method is incorrect, it will lead to the failure of equipment and steel structures. Such examples have often appeared in enterprise production devices in the past few years. Therefore, the selection and construction management of paint should at least achieve the following points:

● first, select paint varieties according to the characteristics of production units. Refining and chemical units often have high temperature and high pressure, low temperature and high pressure, and even high temperature, low temperature, high pressure and low pressure alternately, so the requirements for paint are also varied

● second, select special varieties according to the characteristics of raw materials and materials produced by the production unit. Some materials are alkaline, some materials are acidic, and some materials are neither alkaline nor acidic, but they are very strong solvents. These factors should be considered when selecting paint varieties

● thirdly, the paint type is selected according to the position of the required painting equipment and steel structure in the production device and the process production conditions, so as to avoid unnecessary waste or the paint performance can not meet the use requirements

● fourth, choose the paint type according to the location of the production device. Our country has a vast territory. When choosing the paint type, we need to consider at least the humidity and temperature differences between the South and the north, the air humidity differences between the coast and the inland, and so on

● fifth, after the selection of paint varieties, the construction should be carried out in strict accordance with the characteristics of paint varieties. Such as the treatment of base course, the thickness of single-layer paint film, the total thickness of paint film, the time interval between layers, and the protection of the construction site (wind, air, humidity, direct sunlight, etc.)

in the case, the coating service provider instructed all subcontractors to measure the wet film during the painting process, so as to better control the film thickness, and guided all subcontracts. Therefore, for testing the tensile properties of flexible packaging materials, it is necessary to equip a tensile machine with a large travel distance to construct inorganic zinc rich paint in dry weather and test the curing degree. Before the arrival of winter, the technical service engineer conducted winter construction guidance in advance, It is commendable to avoid paint film defects caused by temperature changes during on-site construction
