Recently, China Petroleum was invited to give a keynote speech on "Introduction to the development and application of China petroleum MPP conduit special material H2464" at the seminar on the promotion and technology of power cable conduit industry standards. The MPP special material H2464 produced by Daqing Refining & Chemical Company has become the only domestic material recommended by China power cable conduit industry, which means that the "new leader" of polypropylene pipe jointly developed and promoted by East China Chemical Sales Company and Daqing Refining & Chemical Company for many years has officially "debuted" and become a benchmark product leading the new industry standards.

Non-excavation modified polypropylene power cable conduit (MPP) is an important part of urban underground pipeline network, which is widely used for power cable safety protection in power plants, substations, power transmission and distribution projects, railway bridge tunnel projects and municipal projects. With the country's vigorous development of new energy industry and the promotion of the "upper reform and lower reform" project, MPP industry is also facing problems such as inconsistent industry norms and standards and inadequate supervision of related industries.

East China Chemical Sales Company keenly captures industry information, keeps a close eye on the needs of market segments, and starts to lay out the market research and performance index collection of MPP whole industry chain from 2019, and cooperates with Daqing Refining and Chemical Company, which is known as the "China Petroleum Polypropylene Pipe Material Production Base", and is deeply involved in the drafting of the new national standard. Combining with international standards and considering the development space, the new national standard defines the main indexes of raw materials, such as tensile strength, ring stiffness and Vicat softening temperature, which has played a constructive and positive role in promoting the development of new energy in the country and protecting the "electric artery" of urban development. The standard will be officially implemented in November 2023.

During the development of MPP special material H2464, Daqing Refining & Chemical Company, relying on excellent scientific research and technical strength and years of experience in pipe production, has repeatedly carried out technical research and improved production technology. Production, sales and scientific research personnel visited the trial production enterprises many times, coordinated the trial production problems on the spot, adjusted the index parameters, and strived to produce marketable products with better performance. The addition of "trump card" new products has enriched the series of fist products of Daqing refining and chemical pipe, and has taken a big step in the transformation and upgrading of refining and chemical enterprises from "oil conversion" to "oil conversion" and "oil conversion to new".
