What is cold rolled sanitary stainless steel seamless pipe?
Leave a message
Sanitary stainless steel seamless pipe is a stainless steel pipe that meets the requirements of sanitary standards. It is mainly used for fluid transportation in the food, pharmaceutical, chemical and other industries, such as in the production process of dairy products, beer, beverages, and medicines.
Characteristics of sanitary stainless steel seamless pipes
Dimensional accuracy: For outer diameters below 51mm, the tolerance of wall thickness and outer diameter is controlled within the range of ±0.05mm; for outer diameters above 51mm, the tolerance of wall thickness and outer diameter is controlled within the range of ±0.08mm. If there are special requirements, communication is required before purchase.
Roundness: For outer diameters below 42mm, it is controlled below 0.8mm; for outer diameters above 42mm, the roundness is below 1mm.
Straightness: For outer diameters below 32mm, the straightness is <1mm/m; for outer diameters above 32mm, the straightness is <1.2mm/m.
Roughness: After cold rolling precision treatment, the roughness of the outer surface Ra≤0.6μm, and the inner hole Ra≤0.8μm. If there is a higher requirement for roughness, the roughness of the outer surface must reach Ra≤0.4μm, and the inner hole Ra≤0.6μm.
GNEE cold-rolled sanitary stainless steel seamless pipe spot and custom introduction
1. High dimensional accuracy, good internal and external surface finish
2. Strong pressure bearing capacity, this kind of pipe is mainly used in equipment manufacturing
3. The length of spot is generally not fixed, generally between 5-7, and the specifications are not easily restricted.
4. Packaging and transportation are generally woven bag packaging, and some customers require wooden box packaging and transportation.
5. Compared with sanitary stainless steel seamless pipes, the custom cycle is longer, generally 20-25 days.
6. The minimum order quantity is generally 500kg.
