Zhejiang Fengfeng Pipe Industy's HDPE Electrofusion Equal Coupler with a smooth surface, SDR7.4, and PN25 is a specific type of electrofusion fitting used in high-pressure pipeline systems, typically in water, gas, and industrial applications.
Technical Characteristics
SDR7.4:
SDR (Standard Dimension Ratio) refers to the ratio of the pipe diameter to the wall thickness. In this case, SDR7.4 indicates that the pipe has a thinner wall compared to higher SDR ratings (such as SDR11 or SDR17), which are designed for higher pressure applications.
The SDR7.4 rating typically indicates the fitting is designed for higher-pressure systems and is commonly used for pipelines that carry liquids or gases under significant pressure.
Applications:
lay underground gas and water system
vacuum and waste-water disposal system
chemical industry system
wastewater treatment system
waste incineration system
the building of swimming pool system
