T/AQB 56-2024 Gasketed and Sealed All-In-One Stainless Steel Hanger Device (Haf Structure)

Scope

Scope: This document specifies the terms and definitions, materials, requirements, test methods, inspection rules, marking, transportation, and storage of anti-slip and anti-leakage fully encapsulated stainless steel clamp devices (Hafner structure) (hereinafter referred to as "clamp devices"). This document is applicable to stainless steel clamp devices made from stainless steel clamps, threaded fasteners, and elastic rubber sealing rings. It is mainly used for the connection of drainage corrugated pipes and is suitable for long-term temperature not exceeding 60°C in traffic, municipal, agricultural and rural drainage and sewage projects, as well as dry toilet renovation projects. It can also be used in industrial drainage and sewage projects. Main technical contents: 1. Chemical composition: The chemical composition of the stainless steel clamps (melt analysis) shall not be lower than the requirements of grade 06Cr19Ni10 in Table 16 of GB/T 3280-2015. This indicator is used to ensure the quality and quality of the raw materials of the stainless steel clamps, thereby ensuring the mechanical properties and corrosion resistance of the anti-slip and anti-leakage fully encapsulated stainless steel clamp devices, so that the connection parts of the pipeline system do not leak water or sewage, and meet the actual use requirements of the project. 2. Mechanical properties: The mechanical properties of the stainless steel clamps shall comply with the mechanical property requirements of the corresponding grades in Table 21 of GB/T 3280-2015. This indicator is used to ensure the quality and quality of the raw materials of the stainless steel clamps, thereby ensuring the mechanical properties and corrosion resistance of the anti-slip and anti-leakage fully encapsulated stainless steel clamp devices, so that the connection parts of the pipeline system do not leak water or sewage, and meet the actual use requirements of the project. 3. System anti-slip performance: It specifie
