Inspection of transportation packaging products

1 Overview

steel barrel is a kind of metal container, which is made of metal materials and has a large capacity to reduce costs. It is generally cylindrical. Steel barrel is an important packaging container. Because of its unique nature, it is assumed that everyone cares about the consequences of this experiment in transportation and turnover. It can resist all kinds of hazards in the general mechanical, climatic, biological, chemical and other external environment. It is widely used in the packaging field of dangerous goods, drugs, food, military products and many other commodities

2. Classification

steel barrels are divided into closed steel barrels and full open steel barrels according to the structural form of their closures and the size of the diameter of the closures. The open steel barrel is divided into four types: small open steel barrel, medium open steel barrel, straight open steel barrel and open necked steel barrel. Each type forms a series according to the capacity specification. According to the steel plate with different thickness, it can be divided into heavy barrel, medium barrel, secondary medium barrel and light barrel

in the export of goods, steel plastic composite barrels and steel buckets will also be used, especially in the packaging and transportation of liquid goods such as paint or coating

3. Production process

the production process of steel barrel can be divided into several steps in terms of function. According to the national standard, the wood-based panel experimental machine has multi-functional experimental uses: first, the cutting of steel plate, the stamping of top and bottom covers and closures, then the rolling and welding of barrel body, next, it needs to pull edges, expand ribs and press corrugations, and finally, the edge rounding makes the barrel bottom cover and barrel body combined. After painting, the steel barrel is made

4. Quality requirements

steel drums for export packaging must comply with the provisions of sn/t inspection procedures for open steel drums of export commodity transportation packaging and sn/t inspection procedures for closed steel drums of export commodity transportation packaging

(1) appearance requirements:

① the graphics/words are clear and correct, the depth is consistent, and the position is accurate

② the can body is not allowed to be spliced. It should be round and smooth without burrs, obvious out of round, concave and convex, mechanical damage and skew. The inside and outside of the can body should be clean without rust

③ the crimping shall be free of iron tongue, the barrel mouth parts shall be complete and interchangeable, and the surface shall be smooth and flat after assembly

④ the paint film shall be flat and smooth, with uniform color, no wrinkle and flowing defects, and the adhesion of the paint film shall not be lower than the provisions of grade A2 in the appendix of gb325

⑤ the zinc layer should be complete and closely organized, without defects such as blistering, and the thickness should not be less than 0.010mm

(2) performance requirements:

① vertical impact drop test, stacking test and sealing test shall be carried out for the performance test of open steel barrel. The inspection method shall be carried out in accordance with sn/t regulations on inspection of open steel drums for transportation packaging of export commodities

② vertical impact drop test, stacking test, air tightness test and hydraulic test shall be carried out for the performance test of closed steel barrel. The inspection method shall be carried out in accordance with sn/t "procedures for inspection of closed steel drums for transportation and packaging of export commodities"

③ the performance inspection method of steel plastic composite barrels shall be carried out in accordance with sn/t "simple connection procedure for inspection of steel plastic composite barrels for transportation and packaging of export commodities"

5. Transportation and storage

steel drums are thin-walled containers, and collision, falling and rolling should be avoided during transportation and loading and unloading. Steel drums should not be stacked in the open air. When stacking, the bottom layer should be placed with cushion
