Can the stainless steel cup be filled with saline?

Answer: Yes, but the saline can not be filled for a long time.

All stainless steel water cups on the market should be tested for salt spray. The purpose is to test whether the material will rust in an environment with high salt spray concentration. Within the specified test time and concentration, stainless steel will be regarded as a qualified material without rusting.

Therefore, the stainless steel water cup can be filled with physiological saline, but once the filling time exceeds the allowable time of the material, the salt will still corrode the material and eventually cause rust.

Because the pipe processing methods of stainless steel water cups are divided into welding and stretching. Due to different processes, the effect on the salt spray reaction is also different. The welded pipe has already damaged the stainless steel at the welding seam during welding, so once such a water cup is filled with physiological saline, it is more prone to corrosion and rust. The most obvious is the blackening of the wire. Since the pipe drawing process does not require welding, it can take a longer time to install the saline solution.

The thermos cup produced by Dongguan Zhanyi Commodity Technology Co., Ltd. uses sufficient materials and exquisite workmanship. In terms of material, we insist on using food-grade 304 stainless steel inside and outside, or a combination of 304 stainless steel outside and 316 stainless steel. The heat preservation time can reach 8 hours, and the cold preservation time can reach 12 hours. We insist on using the AQL1.0 inspection standard, which is far higher than the peer standards, and all links adopt a full inspection system to ensure that each product is a high-quality product. Customers from all over the world are welcome to visit our factory for inspection, and welcome to place orders for cooperation.
