    Stainless steel pipes are often packed and transported in bags, boxes or protective containers. Stainless steel conduits with an outer diameter greater than 6 inches can be transported in bulk, packed or not. The length, outer diameter, wall thickness, finish and transportation method determine the optimal packaging method. Most polishing tubes are packed in wooden cases or boxes made of other suitable materials.

     

    It is necessary to bundle stainless steel pipes, because excessive quantities of stainless steel pipes during transportation may lead to risks such as bending, extrusion deformation or twisting of pipes during transportation. In addition, some other auxiliary measures need to be taken during baling. Flat steel wire belt is generally used for binding, but other suitable materials can also be used. The number of fixed knots depends on the length and weight of the bale.

    1. Automobile industry

    Stainless steel plate not only has high corrosion resistance, but also has light weight, which is very important in automobile manufacturing. A large number of stainless steel plates are required for the manufacturing of automobile shells, and many international famous cars are now beginning to use stainless steel plates as the structural materials of automobiles. Even in high-speed railway, subway and other aspects, stainless steel plate is also widely used.

    2. Water storage and transportation

    Water has high requirements on the environment during storage. Stainless steel plate can effectively ensure the water quality is not polluted when used for water storage. Stainless steel plate is also recognized as a safe, hygienic and efficient water storage material in the world. Stainless steel plate will also be an indispensable material for water storage equipment in the future.

    3. Construction industry

    In fact, stainless steel plates were first used in the construction industry, and then gradually introduced into more fields. Decorative panels on the exterior walls of buildings are generally made of stainless steel plates, which are durable and beautiful.

    In a word, stainless steel plates are widely used. In addition to the above, stainless steel plates can also be seen in the household appliance manufacturing industry. I hope you can have a more comprehensive understanding of stainless steel plate after reading this article. More wonderful content, remember to pay attention to TISCO stainless steel!
