Material identification. No matter whether it is 20 1 or 304 or 3 16, many stainless steel pipes will have these marks, some are straight numbers, some are brands used, some are sus in Japanese standards, but they will all be printed out, so that the steel seal of the health body can clearly know what material it is.
Brand trademark recognition. Like material identification, this is something that stainless steel pipe manufacturers will stamp on the pipe body, which is necessary for brand promotion.
Specification and model identification. It should be said that many stainless steel pipe manufacturers rarely print the specifications of the pipes. Basically, the instructions are posted on the outside of the packaging of the pipe head, but some manufacturers print them, but the quantity is very small.
Thickness identification. In fact, real standards and virtual standards have become commonplace topics. Few manufacturers in the market have the thickness of steel seal, let alone the actual thickness. Not only responsible for the brand, but also responsible for all stainless steel pipe consumers.
Age identification. The steel seal will also mark the factory life of the pipe, which should be a small reference for dealing with after-sales problems.
