Scope
Scope: This document specifies the terms and definitions, materials, product classification, technical requirements, test methods, inspection rules, marking, packaging, and transportation of nodular cast iron fittings for plastic pipe systems. This document is applicable to water supply and drainage pipe systems with a working temperature not exceeding 45°C and a working pressure not exceeding 1.6 MPa, used for connecting to PVC-U, PVC-UH, or PVC-O pipes (hereinafter collectively referred to as "plastic pipes"). Note: The working temperature and pressure are limited by the allowable values of the temperature and pressure of the plastic pipes in the pipe system. Main technical content: 6.1 Appearance: The inner and outer surfaces of the fittings shall be smooth and flat, without cracks, heavy skin, or other surface defects and damage that affect product performance. The sealing working surfaces of the socket and plug shall not have continuous axial grooves. 6.2 Dimensional requirements 6.2.1 Minimum wall thickness: The minimum wall thickness of any point of the nodular cast iron fittings shall comply with Table 2. 6.2.2 Length: The effective length of the fittings shall be specified by the manufacturer in the product manual, and the minimum fitting depth shall comply with 6.2.4 and 6.2.5. 6.2.3 Sleeve connectors and flange converters: The manufacturer shall provide a reference value for the maximum fitting clearance of sleeve connectors and flange converters used for plastic pipes, as shown in Figure 1, and the reference value shall not be less than the data specified in Table 3. 6.2.4 Flange interface 6.2.4.1 Socket flange: The design of the socket flange interface shall comply with GB/T 17241.6. The socket flange is shown in Figure 2, and the dimensions shall comply with Table 4. 6.2.4.2 Plug flange: The design of the plug flange interface shall comply with GB/T 17241.6. The plug flange is shown in Figure 3, and the dimensions shall comply with Table 5. 6.2.5 Fl
