Second, the classification of steel drums and the main parameters

1, steel drums - Class: I - 1 grade steel drums; II - 2 steel drums; III - class steel drums.Steel drum level code is dressed different contents according to the steel drums and dangerous goods packaging requirements, provisions for I, II, III level. Steel drum-level code is a steel drum performance level code classification code, not the quality of steel drums. The Code is divided as required by the International Maritime Dangerous Goods Transport Regulations ". Different level in accordance with the hazard of the goods, steel drums grade requirements. Packing Group I at greater risk; class II packaging a moderate risk; class III packaging a smaller risk.

Steel drums Category: mainly divided into two categories, the five forms:

Category Type
Closed steel drums opening drums
In opening drums
Full opening drums straight opening drums
Opening necking steel drums
Conical opening drums
3, round steel drums and Frame Size:

High capacity inner diameter of the barrel ring bars from corrugated high barrel from the top two ring bars
200,560,850,142,803 19 415
100,430,720,102,802 16 290
804,156,158,210,216 265
50 385 450 - 2 16 235
25 285 410 - 2 16 -
20 285 330 - 2 16 165
4, four-liter capacity and structural dimensions of the rectangular bucket:

Capacity type high barrel barrel barrel width barrel caliber material thickness
4 liters Japanese 241 180 106.5 42 0.25
4 liters Continental 25,516,910,642 0.25
5, the thickness of the steel drums material standards:

Capacity heavy barrel medium-sized barrels of the second medium-sized barrels of light barrel
Barrels are bottom of the barrel, the top
200 1.5 1.2 1.0 1.2 1.0
100 1.2 1.0 0.8 1.0 0.8
80 1.2 0.8 0.8 1.0 0.8
63 1.0 0.8 - 0.5 - 0.6
50 1.0 0.6 0.6 0.8 0.5 0.6
45 0.8 0.5 - 0.5 - 0.6
35 0.6 0.5 - 0.3 ~ 0.4
25 0.6 0.5 - 0.3 ~ 0.4
20 0.6 0.5 - 0.3 ~ 0.4
6, steel drum diameter can be free to design?

Can not. With the deepening of opening to the outside world, more and more export goods, the size requirements of the steel drums but also with international standards.Drums diameter dimensions must comply with the requirements of GB13201. Scientific and reasonable size steel drums, pallets, containers and other modern modes of transport, you can get the maximum utilization of the transport space.

7, how to choose the material thickness of the steel drums?

Based primarily on the performance of the steel drums to choose the thickness of the steel drum material, and to note the following: (1) whether the steel drums turnover: steel drums turnover used to take into account the durability of the steel drums, select material steel drum to the appropriate thicker. The steel drums turnover use disposable packaging, under the premise of ensuring the performance of steel drums, steel drums material selection should be thin. (2) the characteristics of the contents: the choice of the thickness of the steel drums material, selected according to the properties of the contents of the material thickness of the steel drum. The steel drum contents select steel drum material thicker dangerous goods from the safety point of view. Thin steel drums Available in steel drums contents of general cargo. (3) the density of the contents to be considered: in the choice of the thickness of the steel drums material density of the contents. Contents density material steel drum should be thicker. The contents density hour should be selected steel barrel material thin. In short, the choice of the thickness of the steel drum material, that is, to ensure that the steel drum performance but also economical and reasonable.
