Recently, Xinxing Casting Pipe Co., Ltd., a subsidiary of Xinxing Jihua Group, presided over the formulation of the first ISO international standard “Nodular cast iron pipe self-anchoring interface system-self-anchor length calculation method” (ISO 21052:2021), which was officially published and released. The industry’s first international standard developed by a domestic enterprise.
Nodular cast iron pipe self-anchoring technology, and its special interface structure design makes the traditional cast pipe socket interface add self-anchoring characteristics, which provides a new solution for pipeline engineering design and construction technology, and realizes free piers for pipeline laying Design, non-excavation horizontal directional drilling construction, immersed pipe construction, etc., among which the butt-free pier design is promoting the construction technology transformation of ductile iron pipeline engineering.
The pier-free design realized by the use of self-anchoring technology, through the self-anchored interface design of the ductile iron pipe itself, avoids the extraction of sockets, eliminates the cement piers, reduces construction workload, working time and land acquisition area, and improves the project On the basis of efficiency, it reduces the carbon emissions of process manufacturing and provides a standard basis for the application and promotion of low-carbon, environmentally friendly, green and convenient pier-free design technology.
The formulation of international standards for the self-anchoring technology of ductile iron pipes is a firm step for Xinxing cast pipes to implement the concept of “carbon reduction”. Under the global implementation of “carbon peak” and “carbon neutral” situation, Xinxing Cast Pipe, as a leading enterprise in the global cast pipe industry, has actively carried the banner of “carbon reduction” and has fully launched the design, construction plan and production of cast pipe products. The “carbon reduction” work of the whole process of manufacturing, quality traceability and after-sales service will be followed up by uniting industry resources and cooperating with international and domestic colleagues to promote the construction of a carbon emission-related standard system in the cast pipe industry, as well as the research and promotion of energy-saving and consumption-reducing technologies, and jointly promote High-quality development of the foundry industry.
