For business people, of course, it is better to spend as little as possible under feasible conditions. For products such as 304 stainless tubings, we can often see packaging film bags on them. Although they are not heavy, if they are single If the number of purchases is too large, it will also generate a certain amount of economic expenditure, but why do many people have to accept this thing on the 304 stainless tubing when it is obvious that they do not like it? Why do 304 stainless tubings need to be packed in bags?
304 is a general purpose stainless steel that is widely used to make equipment and parts that require a good combination of properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel.
1. After the production of 304 stainless tubing is completed, it must be moved, moved and moved for a long distance. If there is no bag, there will be scratches and scratches on the surface, which will affect the appearance of the surface of the 304 stainless tubing. 2. The packaging itself requires manufacturing costs, and the cost of packaging requires labor costs, the sum of which exceeds the weight of a single bag. 3. If packaging is not required, it should be indicated in the contract that the company will not be responsible for scratches and scratches on the surface of the 304 stainless tubing caused by opening the packaging bag. The packaging bag is nothing more than protecting the surface of the 304 stainless tubing, so most stainless steel pipe users do not have to question this.
A large number of 304 stainless tubings need to be cut. Originally, they were cut with a grinding wheel saw blade, but the accuracy was not up to the requirement. Is there any other cutting method? Large quantities of 304 stainless tubings are best cut with an automatic pipe cutting machine. The automatic pipe cutting machine is controlled by a servo motor, and the number of degrees is high, which can reach the wire level. The cutting tool used is a high-speed steel saw blade. Ordinary grinding wheel blade, high-speed steel saw blade, and vibration cutting can be used, and wire cutting with high precision can be used.
Precautions for cutting 304 stainless tubing:
1. The 304 stainless tubing should be placed horizontally, and the diameter direction should be parallel to the cutter, that is, the cutter should be perpendicular to the longitudinal direction of the pipe to ensure that the diameter of the stainless steel pipe is flat;
2. There must be a margin, especially for mechanical cutting. The blade has a certain width. Only by leaving enough margin can the length of the pipe be sufficient, and the nozzle of the 304 stainless tubing can be adjusted;
3. Manual lubrication should be carried out continuously during mechanical cutting to remove metal debris from the knife edge, so as not to affect the cutting effect.
