On the morning of September 17, the review meeting for two group standards—Stainless Steel Welded Pipes for HVAC Water Systems and Technical Specification for Installation of Stainless Steel Pipes in HVAC Water Systems—was successfully held in the conference room of the Guangdong Stainless Steel Materials and Products Association. As one of the participating compiling units, Guangzhou Mayer Co., Ltd. was represented at the meeting by Yan Guobiao, its Technical Director.


The expert group for this review meeting was chaired by Zhao Lijun, a renowned expert in water supply and drainage for architectural design and a professor-level senior engineer, and also included authoritative experts such as Gong Yue (a standardization expert) and Li Yuye (a senior engineer from the Guangzhou Quality Supervision and Inspection Institute). After listening to the report on the standard compilation explanation, the participating experts carefully reviewed the draft documents for the standards and conducted on-site inquiries. Through in-depth discussion and analysis, they put forward specific revision suggestions.

All members of the expert group agreed that the compilation of the two standards complies with national laws, regulations and standardization norms, and is consistent with current national and industrial standards. The standards have a reasonable structure, and the documents submitted for review are complete. The standard Stainless Steel Welded Pipes for HVAC Water Systems specifies contents such as the classification, codes and technical requirements of the pipes, and is scientific, systematic and applicable; Technical Specification for Installation of Stainless Steel Pipes in HVAC Water Systems standardizes the installation process, which helps improve installation quality and prevent and control risks in pipeline systems.


Guangzhou Mayer has always attached great importance to the development of industry standards and actively participates in the formulation of various standards. By participating in the compilation of these two group standards, the company has demonstrated its technical strength and sense of industry responsibility in the field of stainless steel pipes, and made due contributions to promoting technological progress and high-quality development of the industry.

After the meeting, the compiling group will revise the standards in accordance with the expert group's opinions, formulate a submission draft for approval as soon as possible, and submit it for filing. The standards are planned to be released in the near future. Guangzhou Mayer will continue to pay attention to and support the promotion and implementation of the standards, and provide customers with higher-quality products and services.
