Sealed and Locked Spill Containers（D400）

1、Manhole cover and barrel are made of SMC composite material, offering superior mechanical properties,corrosion resistance, and aging resistance.
2、Barrel and base feature a seamless integrated design, ensuring long-term stable and reliable sealing performance, achieving air-tightness standards.
3、Operating temperature range is -50°C to 150°C, suitable for harsh environments.
4、The butterfly valve and oil drain valve are custom-developed and produced, making oil drainage more effortless and convenient.
5、The ball valve reliably seals the internal oil and gas of the tank, preventing the diffusion of oil and gas, which reduces risks and pollution.
6、Any accidentally spilled oil can be quickly directed into the oil discharge pipeline, avoiding contamination and waste.

BETTER COVER R&D and design with safety as the primary starting point.
Spill containers manhole covers and frames are made of SMC composite materials, which are anti-static and safer!



At the same time, the composite manhole cover and frame adopt a sealing structure and locking mechanism to effectively prevent the entry of rainwater from the ground and effectively protect the internal equipment，the manhole cover with locking is safer

The spill containers on the market uses cast iron manhole covers, which are prone to sparks and bring safety hazards.
At the same time, cast iron manhole covers and frames cannot be sealed, and surface rainwater will enter, which will reduce the service life of internal equipment.



Sealed structure with locking device and composite manhole cover and frame

BETTER COVER has upgraded the oil unloading anti-overflow handhole well structure, using SMC composite materials for the barrel body and base, and forming them in one piece under high temperature and high pressure, making the product more sealed and safer as a whole.

The barrel body and base of this product on the market adopt a splicing structure, which is prone to gaps when installed improperly.
