First, the health concept of seamless elbow

Seamless elbow is a common pipe connector, usually made of stainless steel, carbon steel and other materials. In the pipeline system, the seamless elbow is mainly used to connect the turn or connection of the pipeline line in different directions, and plays a role in changing the flow direction, diverting, and confluence. In the industry involving liquid, gas and other fluid transmission, such as food, medicine and other fields, the health requirements of the pipeline system are particularly strict, and the health problems of seamless elbows can not be ignored.

From the point of view of hygiene, seamless elbow should have the following characteristics: smooth surface, no burrs, no pores, no cracks, no rust spots and other defects; The materials should meet food grade or medical grade standards and should not contain harmful substances; Joints should have no leakage, no dead corners, easy to clean, etc. These characteristics are related to the transmission efficiency of the fluid in the pipeline, but also to whether the fluid is contaminated, so as to ensure the quality of the product.
