At about 23:30 on August 12, 2015, the dangerous goods warehouse of Tianjin Dongjiang Bonded Port Area Ruihai International Logistics Co., Ltd. located in Tanggu Development Zone of Tianjin Binhai New Area exploded. As of 21:00 on August 13, 2015, the explosion has caused 50 deaths.
1. Fire-fighting equipment mainly includes fire extinguishers, fire hydrant systems, fire rescue tools:
1. Fire extinguishers include dry powder fire extinguishers, carbon dioxide fire extinguishers, household fire extinguishers, vehicle fire extinguishers, forest fire extinguishers, stainless steel fire extinguishers, water fire extinguishers, hanging fire extinguishers, gun fire extinguishers, fire extinguisher boxes, fire extinguisher racks, etc.
2. Indoor fire hydrant system, including indoor fire hydrant, water hose and water gun.
3. Demolition tools, including fire axe, cutting tools, etc. As for the others, they belong to the fire protection system, such as automatic fire alarm system, automatic sprinkler system, smoke control system, fire separation system, fire broadcast system, gas fire extinguishing system, emergency evacuation system and so on.
A fire extinguisher is a portable fire extinguisher that can be moved by humans. It can spray the fire extinguishing agent under its internal pressure to fight a fire. There are many kinds of fire extinguishers, and the scope of application is also different. Only by correctly selecting the type of fire extinguisher can effectively fight different types of fires and achieve the desired results. China's current national standards divide fire extinguishers into portable fire extinguishers and push-type fire extinguishers. The following is a brief introduction to the classification, application and use of portable fire extinguishers that people often see and come into contact with.
Second, the classification of fire equipment <fire extinguisher>:
Fire extinguishers can be divided into five categories according to the installed fire extinguishing agent:
1. Dry powder fire extinguishers. There are two main types of fire extinguishing agents, namely sodium bicarbonate and ammonium phosphate fire extinguishing agents.
2. Carbon dioxide fire extinguisher.
3. Foam fire extinguisher.
4. Water fire extinguisher.
5. Halogenated fire extinguishers (commonly known as "1211" fire extinguishers and "1301" fire extinguishers)
Fire extinguishers can be divided into three categories according to the pressure type of the fire extinguisher:
1. Gas storage fire extinguisher. 1. A fire extinguisher that is driven by a compressed gas or liquefied gas released from a gas cylinder on a fire extinguisher.
2. Gas-filled fire extinguishers. Fire extinguishers are fire extinguishers driven by the pressure of compressed gas or fire-fighting vapor in the same container.
3. Chemical reaction type fire extinguisher. Extinguishing agent is a gas pressure driven fire extinguisher produced by a chemical reaction in a fire extinguisher.
Graphite Electrodes mainly use needle coke, petroleum coke, as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, Graphite Electrode with low resistivity, graphite electrode good conductivity, graphite electrode low ash, graphite electrode uniform and compact structure, good oxidation resistance, high mechanical strength, etc.
Our graphite electrode was made of high-quality petroleum coke, needle coke, coal tar pitch and other low-ash raw materials. Processing by calcining, ingredients, mixed kneading, molding, roasting and pressure impregnation at 3000 ℃ high temperature graphite. We offers the most demanded standard graphite electrodes and nipples. Our graphite electrodes include RP, HP and UHP grades. They are widely used in electric arc furnaces (EAF) and ladle furnaces (LF) for the melting of steel, non-ferrous metals and some non-metallic minerals.
Advantage
1. High quality and strictly inspected petroleum coke, needle coke as raw material.
2. Low specific resisvitiy
3. Low conspumption rate
4. Anti-oxidation, uniform strength
5. Good resistance to thermal shock
6. Perfect match betwee body and nipple.
7. Professional , experienced reliable and safe package & transportation
