D400/C250 Heavy Duty Composite Manhole Cover and Frame With Or Without Inspection Hole, Sealed, Lockable

M & C brand pipework is one kind of thermoplastic composite pipeline for underground installation at petrol filling stations. It can not only solve the problems of eccentric wear and corrosion, but also prolong the service life of double-layer composite pipes in gas stations to a certain extent, and can also detect whether the pipes leak through the space between the inner pipe and outer pipe. The inner pipe has EVOH resin, which ensures the anti-leakage performance of the pipework and can effectively prevent the pipework from being corroded by various fuels, ethanol mixtures and additives. This feature is applicable to all fuel groups that may be encountered in the world. The inner pipe is provided with an antistatic layer to ensure the safe use. The inner space of the double-layer structure connects all the pipes connecting the underground oil storage tank to the dispenser. When the inner pipe leaks, the fuel will flow to the lowest point of the pipe, and the leak detection device installed here will give an alarm; Or when the outer pipe leaks, the equipment will also give an alarm. Thereby ensuring the complete prevention of groundwater and eliminating the possibility of fuel spilling into the environment.

Fuel Tank Sump is a kind of protective container, which is installed at the mouth of buried oil storage tank, providing a clean space for equipment, valves and joints, ensuring its internal equipment is not corroded by groundwater, and ensuring the normal operation of the oil tank and its auxiliary equipment. At the same time, ensure the fuel will not leak into the soil during equipment failure and maintenance, and protect the soil of the oil station from pollution. When the equipment, valves and joints in the tank mouth need to be inspected, repaired and maintained, the use space of Tank Sump allows maintenance personnel to enter its interior, and can scrub and ventilate the tank mouth. Regular inspection of liquid level meter, submersible pump, oil unloading overflow valve and leak detector on Pipework System, liquid level calibration at oil measuring hole, and maintenance of joints and valves of oil transportation, oil unloading, breathing pipelines and various oil vapor recovery pipelines can be easily completed in this space.

Dispenser Sump is a kind of protective container, which is installed under the dispenser to provide a clean space for the valves and joints at the bottom of the dispenser, to ensure that its internal equipment is not corroded by groundwater, and to ensure the normal operation of the dispenser and its auxiliary equipment. When the internal equipment, valves and joints of the dispenser need to be inspected, repaired and maintained, the use space of the Dispenser Sump allows maintenance personnel to easily operate, and can scrub and ventilate the bottom of the dispenser to avoid excessive oil vapor concentration. When the gauges, filters, emergency cut-off valve, triangular flange and high-pressure bellows above the space are regularly inspected and repaired, the fuel will not leak into the soil, thus protecting the soil of the oil station from pollution. Dispenser Sump is made of high-strength engineering plastics /SMC composite materials, and its excellent material properties make the products available in all oil stations around the world.

M&C 1100X1100mm lightweight Composite Gully Grating have widely application for fuel station construction companies, city utilities, telecommunications and design and civil engineering companies requiring a lightweight and operational access solution.

Balance Breakaways, also known as safety cut-off valve, means that in case of emergency, the valve will close quickly to avoid accidents. According to different use positions, Balance Breakaways can be divided into Emergency Shut-off Vale & Vapor Recovery Breakaway.
