Aluminium alloy manhole cover

MC company focuses on designing and developing all kinds of refueling Nozzles:Vapor Recovery Nozzle，Automatic Nozzle，Automatic AdBlue Nozzle，Nozzle With Mete，Manual Nozzle,etc.Meet various needs of customers. Pressure Casting technology improves the compactness of Nozzle body material, makes the appearance more beautiful and the inner wall smoother, which effectively reduces the resistance of liquid flowing in the nozzle body. 100% Factory inspection & test to ensure products quality. The main material of the sealing device used in the product is Silicone-Fluorine compound rubber, which has excellent low-temperature elasticity, high-temperature tensile retention rate and low swelling rate of hydrocarbon mixture in liquid immersion.

MC series vapor hoses include ordinary fuel vapor hose and oil-gas vapor recovery hose.MC vapor hose is composed of inner rubber layer, metal braid layer and outer rubber layer. The metal braid layer of the hose makes it have excellent kink resistance, low elongation and long service life. MC vapor hose is suitable for gasoline and diesel oil, including oxygenated fuel and gasoline with additives. MC vapor recovery hose is a kind of oil-gas reverse coaxial hose, which is used in oil-gas recovery system. During refueling, one end is connected with oil-gas separator, and the other end is connected with recovery nozzle or breakaways. The middle of the hose is for gasoline vapors, and between the middle and the outer hose is for oil. When refueling, gasoline vapors are pumped into the underground oil tank .

Oil vapor recovery system refers to the process of loading and unloading fuel or refueling vehicles, which collects volatile oil vapor, Through the methods of assimilation, adsorption or condensation etc, to reduces the pollution of oil vapor , or makes oil vapor change from gaseous state to liquid state and then to gasoline again, so as to achieve the purpose of recycling. When the dispenser is operated to refuel, volatile oil vapor will overflow from the automobile fuel tank, and this kind of vapor will also be produced by the fuel flow.Vacuum Fuel Pump will work at this time to extract the vapor and inject it into the pipeline which connected with the oil tank for further treatment.

Meter measures the volume of liquid, gas and other media flowing through the equipment, and displays the specific values or sends them to the display equipment in the form of signals. This series of products has the characteristics of large flow, long service life, high metering accuracy and easy installation, and is widely used in various use environments. Meters are divided into dispenser meters, Turbin Electroneic Flow Meter, Mechanical Flow Meter, Gas Roots Flow Meter, etc. This kind of design is widely used in the measurement of various fuels, urea, oil vapor, etc., providing accurate measurement data for fuel filling and on-line detection equipment.

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.

This type product include Hose Accessories、Vapor Recovery Adaptor、Vapor Recovery Sight Glass、Vapor Recovery Proportional Valve,Essential Oil Filter, etc. Vapor recovery proportional valve（vapor recovery separation and gas-liquid ratio adjustment combined into one）is used in conjunction with the secondary vapor recovery system to separate the vapor recovery paths and adjustment the gas-liquid ratio according to requirements. The vapor recovery separation joint is an oil sight glass and a visual separation joint for observing whether air is mixed in the liquid fuel.

Clear opening 900x900mm for city construction composite FRP manhole cover have widely application for gas station, road builders, fuel station construction companies, water authorities, city utilities, telecommunications and design and civil engineering companies requiring a light weight and operational access solutions. In China ,  PetroChina, SINOPEC and other fueling stations are our loyal clients for many years. In abroad,  UK, USA, Australia , Kenya , Uganda, Singapore, Malaysia and other countries are using our covers always.

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.
