Jan 17,2022

There are many types of stainless steel pipes. Many people do not know the difference between stainless steel decorative pipes and stainless steel sanitary pipes. Then, let's learn about the difference between stainless steel decorative pipes and stainless steel sanitary pipes!
Stainless steel sanitary pipe contact with food, because the contact objects are ingested by the human body, so the quality of the pipe is very strict. Mainly used in food, dairy products, beer, salt, beverage production of pharmaceutical, biological engineering and other industries. It is mainly used for decoration works such as stairs and guardrails. The material of stainless steel decorative pipe is mainly 201 and 304, with a small amount of 301 and 316. Categories are ordinary tube, flower tube, color tube and so on.
1. thickness: The thinnest thickness of the sanitary tube is the actual thickness of 1mm, generally 1.2 and 1.5, but the actual thickness of the stainless steel decorative tube is generally below 1.2.
2. internal and external welding treatment: sanitary pipe, the need for internal and external leveling. That is to say, the internal and external welding must be treated, but the stainless steel decorative tube, as long as the outside treatment can be.
3. grinding: sanitary tube needs internal and external grinding, decorative tube generally only external grinding.
4. scope of application: sanitary pipe is mainly suitable for food engineering, beverage engineering, stainless steel decorative pipe is mainly suitable for stair handrail, guardrail, security window, villa fence, etc.
Stainless steel pipe is a long steel with a hollow cross-section and no seams around. The thicker the wall, the more economical and practical it is, the thinner the wall, the higher the processing cost. The technology of the product determines its limit performance, and the precision of the seamless steel pipe is generally low. Black spots are not easy to remove; their detection and shaping must be processed offline. The wall thickness is uneven, the appearance of the tube is low, the cost of sizing is high, and there are pockmarks on the inner and outer surfaces. Stainless steel sanitary pipes are mainly used in beverage, alcohol, biological engineering, food and other production equipment and pipelines.
Most stainless steel sanitary pipes use 304 stainless steel pipes. As one of the widely used steels, 304 stainless steel sanitary pipes have good corrosion resistance, heat resistance, low temperature strength and mechanical properties, and have good stamping, bending, and hot workability. National standards require that it is mainly used in the fields of water supply and drainage, hot water, cold water, heating, and direct drinking water. No heat treatment hardening phenomenon (non-magnetic, use temperature -196~800). It can be used for household goods (tableware, cabinets, indoor pipes, water heaters, boilers, bathtubs, auto parts, windshields, scarves, plastics), medical equipment, building materials, chemicals, food industry, agriculture, ship parts.
In short, there is little difference in the material between stainless steel decorative pipes and stainless steel sanitary pipes. When choosing stainless steel decorative pipes, a strong and reputable stainless steel pipe manufacturer with after-sales service is more secure. Mainly production technology, stainless steel sanitary pipe is much stricter than stainless steel decorative pipe.
