The T-shaped EPDM (terpolymer ethylene propylene) gasket made of ductile iron pipe benefits from its material properties and the T-shaped structure's compatibility advantage. It is the high-end sealing choice for the socket connection of ductile iron pipes. The core selling points are as follows:
1. Excellent weather resistance and temperature resistance: It can withstand a wide temperature range of -40℃ to 120℃. Even in the harsh winter in the north, it will not crack or lose elasticity, and it can also maintain stable sealing in high-temperature environments. It is also resistant to ultraviolet rays and ozone, and will not crack or age under long-term outdoor or buried use. It is suitable for outdoor pipeline laying in different climate regions.
2. Excellent chemical stability: It has good tolerance to active substances such as weak acids, weak bases, and oxidants in tap water and sewage. It can also adapt to some mild corrosive media in the chemical industry. It will not contaminate drinking water and can resist erosion from sewage and high-salt coastal environments. Compared with SBR gaskets, it is applicable to a wider range of media.
3. Reliable sealing and leak prevention performance: The T-shaped structure precisely fits the sealing groove of the ductile iron pipe socket, combined with the flexible design of the interface. When the pipeline experiences slight displacement or deflection due to foundation settlement or thermal expansion and contraction, the rubber ring can dynamically adhere to the interface. Moreover, it has a self-tightening effect. The greater the fluid pressure inside the pipeline, the stronger the contact pressure between the rubber ring and the interface, which can completely eliminate the problem of leakage.
4. Extremely long service life: The EPDM material itself has excellent resistance to aging among common rubber materials. After professional testing, the service life of this type of gasket suitable for ductile iron pipes can reach nearly 140 years, which can match the long service period of ductile iron pipes, significantly reducing the cost of later replacement and maintenance.
5. Installation adaptability is convenient: The texture is suitable for the installation requirements of T-type socket-joint interfaces, and no welding assistance is needed. It can be quickly installed by a 2-person team, with an efficiency twice that of steel pipe installation. At the same time, it is compatible with various specifications of ductile iron pipes ranging from DN50 to DN2600, and complies with multiple international standards such as GB/T21873 and ISO4633. It is suitable for pipeline construction in various scenarios including municipal and industrial applications.
6. Safety and Compatibility: Equipped with excellent insulation properties, it can prevent pipeline corrosion caused by stray currents in such environments. It is suitable for pipeline laying in special areas such as tunnels. Food-grade materials are available for selection. When used in drinking water pipelines, it will not release harmful substances, meeting environmental protection and safety standards.
