Review meeting of Building Materials sector standard was held by TC 197 on February 25, 2023, and Process Technology Code of Practice for Cement Products- Part 1: Concrete and Reinforced Concrete Sewer Pipes formulated by CCPA successfully passed the technical review.

The revised standard Process Technology Code of Practice for Cement Products- Part 1: Concrete and Reinforced Concrete Sewer Pipes was first released in December 2012 and implemented in June 2013. As basic specification that should be strictly followed in the production process of concrete and reinforced concrete sewer pipes (hereinafter referred to as sewer pipes), the standard has played a positive role in promoting enterprises to strengthen technical management and improve product quality. With the continuous improvement of sewer pipe technology and equipment level in China, the original standard can no longer meet the needs of innovative technology promotion to a certain extent. The revision was initiated in December 2020.

The standard is revised based on the investigation of the production process and actual engineering application status of sewer pipe production enterprises in China, combined with experimental verification of the technical parameters of sewer pipe production process, and fully considering the high-quality development trend and requirements of the sewer pipe industry, with a focus on supplementing, adjusting, and improving some technical requirements for raw material quality control, concrete preparation, and pipe forming. The revised standard has clear process steps, clear key control points, and strong operability. After the release and implementation of the standard, it will play an important role in further improving the production technology level and product quality of sewer pipes, expanding the market space and application fields of sewer pipes, and promoting industry technological progress.
