Oil tanker oil and gas recovery system uses: In the process of loading and unloading the tanker, fully enclosed gas is recovered, and the emission of oil and gas to the atmosphere is limited. While the tanker is pumping oil through the helium line, the oil and gas in the gas station tank returns to the tanker through the return line. Tanker trucks bring oil and gas back to the oil depot for processing to achieve the goal of oil and gas recovery.

Subsea Valve Uses: Subsea valve series, also known as the emergency shut-off valve, is installed at the bottom of the tank and can replace the traditional top-mounted refueling for bottom loading and refueling, making the operation of the staff easier, time saving, safe and environmentally friendly. A cutting groove is designed on the valve body. When an accident occurs in the tanker, the cutting groove is disconnected, and the bottom pipe and the tank body are cut off without affecting the sealing of the tank body, thereby effectively preventing the oil leakage in the tank and ensuring the oil. Pot security.

Breathing valve use: When the breathing valve dumps 70o, the sealing ball in the valve dumps to form an effective seal to prevent oil leakage.

The purpose of the oil hole is to install a dipstick or a liquid level gauge on the prepared opening on the manhole cover.

Usage of safety valve: Designed for tanks, chemical tanks, and other cans. Set different opening pressures according to user requirements to meet different needs. The main body is made of stainless steel as a whole, which is corrosion resistant and highly closed. It is suitable for various environments.

Anti-overflow sensor: Application: Anti-overflow electronic sensor is widely used in a variety of container tanks in the closed liquid filling, in order to prevent the overflow of the liquid and a warning device in advance, it is installed in the top of the container tank manhole Cover, when the oil level reaches the warning limit, the sensor will automatically alarm to break the brake.


Chromium Carbide Overlay Blast Furnace Wear Parts

The blast furnace uses steel plates as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into 5 parts from top to bottom: furnace throat, furnace body, furnace waist, furnace belly and furnace hearth. Due to the advantages of good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron output.


During the production of blast furnace, iron ore, coke, slag-making flux (limestone) is loaded from the top of the furnace, and preheated air is blown in from the tuyere located at the lower part of the furnace along the furnace periphery. At high temperatures, carbon in coke (some blast furnaces also spray auxiliary fuel such as pulverized coal, heavy oil, natural gas, etc.) burns with carbon monoxide and hydrogen produced by the oxygen blowing into the air to remove iron ore during the ascent in the furnace Oxygen, thereby reducing iron. The molten iron is released from the iron mouth. Unreduced impurities in iron ore combine with flux such as limestone to form slag, which is discharged from the slag port. The produced gas is discharged from the top of the furnace, and after dedusting, it is used as fuel for hot air furnace, heating furnace, coke oven, boiler, etc. The main products of blast furnace smelting are pig iron, as well as by-product blast furnace slag and blast furnace gas.
