How to recycle the waste steel barrel

Recycling of waste drums purposes in many respects , the most important thing is the restructuring of steel drums . There are various forms of restructuring , summed up in the following categories:

Placed on the roof of the old drums for water storage tank , plus welding inlet pipe and outlet pipe can be made ​​simple water ; the drums from the barrel body cut open along the diameter can be made washtub ; cutting along the axis of the drums open can be used for livestock manger, there are people in rural areas use it as a bathtub ; him square in the bucket to open a big mouth , and then welded on the valve in the bottom of the barrel , you can pull on a tricycle as a tool for water and water storage ; Some people use it as a solar water heater tank or shower , etc. ......

Such restructuring can be made a little everyday items .

Old drums due to transport and other processes used in the bump, pits and barrels are often deformed barrel body with barrel top and bottom edge of the paper are also more distortion , more difficult round . In order to use it again to make new steel drums , one approach is to curl the bucket along the top and bottom of the barrel cut down, after cleaning the barrel body flange , together with a new barrel top and bottom of the barrel , and then seaming so manufactured drums lower height than the old barrels , the capacity will be smaller. Old barrel top and bottom can be used to produce some of the smaller diameter drums top and bottom , you can also make other products.

Converted into a smaller capacity drums is their another form .

Use of the old barrel steel production of other products. Old drums using the cutting method will split into three parts, namely barrel top , bottom of the barrel and the barrel body , and then cut to the part difficult to use , will be able to use part of cleaning and flattening . Flatten the material can be processed as a rough sheet other products .

Reuse of waste drums value is high, but the restructuring process is sometimes more complicated, but also often dangerous occurrence . Often when the restructuring of the steel drums accidents, primarily the burning and explosion. Since the restructuring of steel drums are generally inseparable from welding operations, welding and cutting steel drums , often because the barrel of the residual exposure to gasoline and flammable gas welding, flame cutting and cause explosion. So the drums of welding and cutting operations, must be taken to demolition , cleaning, replacement and other measures in order to carry out welding and cutting operations.

1 scrap steel drum cleaning welding , cutting , specific methods are as follows:

First, the barrel was a net surplus of flammable liquids , and then use caustic soda ( sodium hydroxide ) solution into the barrel for cleaning. The amount of caustic soda , generally each capacity of 200 barrels using a 0.5 liter gasoline kilograms. When washing , three times with 0.5 kg caustic soda . The first half of the steel drums of water coming down , put one-third of caustic soda , the port is blocked for half an hour after the hard rock bucket , then empty the water , so continuous cleaning three times. Then wash with water once or twice before welding . If not immediately after cleaning welding , cutting , and stored for a period of time , you must re- rinse with water once or twice before welding and cutting . Otherwise, it has not been cleaned for a small amount of gasoline will be volatile flammable vapors , and the explosion of a gasoline explosion limit as low ( 0.76% to 7% ) .

2 scrap steel drum replacement welding, concrete steps are as follows:

First barrel was a net residual gasoline , poured them into inert gas such as nitrogen , and then rinse with air , followed by replacement of two or three times, then rinse inert gas , you can be hot work welding . If inert gas , steam can be replaced , but to appropriately increase the number of replacement .

3 drums of waste water welding , the specific process is:

If the barrels of gasoline welding point is only the tip of the barrel above the drums of the site , you can put the net after petrol , rinse with water once or twice , and then in the barrel filled with water , so that the container does not accumulate flammable vapors . This method is relatively simple, but has its limitations. Welding in steel drums next to any other parts , you must clean out the inside drums or filled with water , because for welding , not only welding Mars would endanger the safety of steel drums , steel drums and electric welding causes is live , welding wire connections at the spark may occur when power is applied .

If repair welding , steel drums After welding , the weld should be promptly checked whether with water seepage , leakage is found , they should immediately repair welding .Otherwise, over a period of time a leak is discovered , the need for welding when they have to repeat the cleaning and other processing.

Notably , some people use the old drums when the boiler , which is extremely dangerous , domestic accidents have been more so since . Drums non- pressure vessels, just plain metal packaging, so in old barrels regeneration benefits should be careful not to violate the nature of steel drums for restructuring and use.

Welding, cutting equipment and energy use , while having a certain fire hazard , but the fire and explosion incidents, is that these are not the main equipment and energy itself, while the vast majority is due to welding, cutting jobs in the ideological paralysis, improper operation, the system is lax , poor implementation of security measures caused . So the key is to pay attention and prevention. Preparatory work to do before the operation safety , operation should be carried out strictly according to the rules , the job to be performed after meticulous security checks.
