The T-shaped NBR (nitrile butadiene rubber) gasket made of ductile iron pipe has the main advantage of sealing for oil-based media. It is suitable for various scenarios involving oil and related fluids. The key selling points are as follows:
1. Outstanding oil resistance: This is its core strength. It can effectively resist the erosion of various oils such as lubricating oil, diesel, gasoline, and petroleum-based and aliphatic solvents. Even when in prolonged contact with oil-based media, it will not swell or deform, and the sealing performance remains stable. It is the preferred choice for sealing in oil transportation pipelines.
2. Strong sealing compatibility: The T-shaped structure precisely fits the sealing groove of the ductile iron pipe socket. During installation, the inserted part exerts pressure on the socket, generating contact pressure. It also has a self-tightening effect. The tighter the fluid pressure, the more secure the sealing. At the same time, it is compatible with slight axial expansion and deflection of the pipeline, capable of coping with interface displacement caused by foundation settlement and preventing leakage.
3. Durability suitable for industrial scenarios: The material has excellent wear resistance, capable of withstanding wear caused by soil compression and medium erosion during pipeline installation and use. It also has good aging resistance and is unlikely to harden or crack due to long-term use. It can operate stably within the normal temperature range of -20℃ to 100℃, meeting the majority of industrial and municipal normal temperature working conditions.
4. Compatible with multiple media and ensuring safety: Besides being resistant to oil, it can also withstand the erosion of oily wastewater, some mild chemical media, and wastewater with fluctuating pH values. It is suitable for transporting special wastewater such as that from dining areas. At the same time, it has strong sealing performance, which can prevent the leakage of oil and wastewater to contaminate the soil and water bodies, ensuring environmental safety.
5. High cost-effectiveness in installation and maintenance: The material is soft and compressible, and the socket-type installation does not require complex tools. The construction efficiency is high, and it is also compatible with various specifications of ductile iron pipes. Its stable performance can reduce the frequency of maintenance and replacement due to sealing failure, lower the maintenance cost of the pipeline in the later stage, and is suitable for large-scale industrial and municipal oil pipelines.
