Manhole Cover is installed on the top of the tanker to prevent the inside fuel from leakage when the tanker is over rolled. With P/V vent inside to adjust the pressure. When there is pressure differences inside and outside the tanker, it will automatically inlet or exhaust air to adjust the pressure so that it can ensure the safety
andenvironment protection. It is suitable to transpore petroleum, diesel, kerosene, and the other light fuel, etc.

The covers usually feature "pick holes", into which a hook handle tool is inserted to lift them. Pick holes can be concealed for a more watertight lid, or can allow light to shine through. A manhole pick or hook is typically used to lift them, though other tools can be used as well, including electromagnets.
Product characteristics
The square ductile iron manhole cover is strong and durable, with good tensile strength and pressure resistance. Compared with resin composite and cement rainwater inlets, the elongation rate is much higher, with good pressure resistance and not easy to be damaged. At the same time, ductile iron manhole covers are generally divided into round and square. In urban road administration, round manhole covers are generally used because round manhole covers are not easy to tilt and can better protect the safety of pedestrians and vehicles. In residential areas, rural areas or on both sides of urban roads, square covers are generally used to better prevent the entry of liquids such as rainwater.
1. The characteristics of square cast iron manhole covers are firmness and durability. Cast iron is a material with high density, high hardness, firmness and durability. It can withstand great pressure and weight and is suitable for road and vehicle transportation. Square cast iron manhole covers have good economy and practicality. They have a long service life and do not need to be replaced frequently, saving the cost of later maintenance.
2. As a municipal facility, square cast iron manhole covers play an important safety role. It can effectively protect equipment placed underground, such as sewers, cables, telephone lines, etc., prevent engineering facilities from external damage, and ensure the stable use of urban infrastructure. At the same time, it can also prevent people and animals from falling into the well, ensuring the safety of people's lives and property.
3. The appearance of square cast iron manhole covers is beautiful and generous, and it is an important part of urban construction. Designers have invested a lot of energy in the design of square cast iron manhole covers, fully considering its use and aesthetics. Square cast iron manhole covers can also be customized in shape and size according to different road conditions, making urban construction more coordinated and beautiful.
