Standards Development

Scope

This International Standard specifies the terms and definitions, classification and marking, technical requirements, test methods, inspection rules, signs, packaging, transportation and storage of bamboo winding composite pipes.

It is applicable to bamboo winding composite pipe with a nominal diameter of 150 mm - 3,000 mm, pressure level not greater than 1.6 MPa, ring stiffness class of 5000 N/m2 - 20 000 N/m2, operating ambient temperature of -40°C - 80°C, with a maximum temperature not exceeding 90°C for the transmitted medium, for hydraulic, municipal, industrial water supply and drainage works applications.

Purpose

Traditional pipes such as metal corrugated pipes, plastic pipes, and cement pipes have been widely used in global infrastructure construction for many years, but they pose multiple hazards to the ecological environment. According to the United Nations Environment Programme, the annual environmental remediation costs generated by the production and disposal of traditional pipes worldwide exceed $12 billion, becoming a key bottleneck restricting carbon neutrality goals and the development of circular economy.

Bamboo has the advantages of fast growth rate, bamboo maturity, and short rotation period, making it an excellent natural renewable and biodegradable resource. The bamboo industry, which develops and utilizes bamboo resources, is a globally recognized green and low-carbon industry. It provides economic income, food, and housing for 2.5 billion people worldwide every year, and the annual trade volume of bamboo products worldwide exceeds 8.5 billion US dollars. Bamboo wrapped composite pipe is a new type of bio based pressure pipeline made of bamboo as the substrate and processed through winding technology. It has the characteristics of energy saving and emission reduction, carbon sequestration and storage, lightweight and high strength, good insulation performance, seawater corrosion resistance, good sound insulation performance, and good fire resistance. Bamboo wrapped composite pipes have significant economic and environmental benefits as they can replace most traditional pipes in the market, such as spiral welded pipes, prestressed steel cylinder concrete pipes, plastics, and metals, at a lower cost than traditional materials. At present, there are no bamboo winding related standards in the ISO international standards, which limits the development of bamboo winding composite pipes in the international market. The formulation of this standard can significantly enhance the visibility of bamboo winding composite pipes in the international market, promote the standardized development of the bamboo winding composite pipe industry, and contribute to the global green environmental protection cause.

The development and implementation of the ISO international standard for "Bamboo Wrapped Composite Pipe" is in line with the national industrial development policy in the current global era of carbon peak and carbon neutrality. It is of great significance for the development of the bamboo industry and the promotion of its green and low-carbon transformation. Therefore, a proposal for the ISO international standard for "Bamboo Wrapped Composite Pipe" is proposed.
