Food Grade 304 Stainless Steel Pipe vs Industrial Stainless Steel

Posted by Deepak Seth on January 17th, 2023

Food-grade 304 stainless steel pipe is a type of stainless steel pipe used in the food industry. It is corrosion-resistant and heat-resistant. In the food industry, it can also be used as a heat exchanger or as an insulator due to its chemical resistance. What are the benefits of stainless steel pipe? In food processing plants, stainless steel pipes are widely used for heat transfer and cooling. It is suitable for food industry processing because it has excellent corrosion resistance and high chemical resistance. Additionally, it has good electrical insulation properties so it has high electrical conductivity and low electrical resistance.

1. Composition of heavy metals

There is a significant difference between food grade 304 stainless steel pipe. Industrial pipe in that the heavy metal content is much lower in food grade 304 stainless steel pipe. 

In this section, we will discuss the composition of heavy metals in stainless steel pipe and industrial pipe. A professional writer with a background in chemistry, physics, and industrial pipe wrote the content. Heavy metals in stainless steel pipe: Stainless steel pipe is made from a variety of materials that are difficult to distinguish from one another. As a result, it is difficult to describe heavy metals in stainless steel pipes. For this purpose, we will focus on six basic types of materials: aluminum, copper, lead, magnesium, zinc, and more. As each of these materials has different properties, we will describe them based on their properties rather than their types. 

In stainless steel pipes, aluminum is used for two purposes:

1) It is an alloy that is easy to machine

2) When exposed to water, it is highly corrosion-resistant.

2. The surface

The surface is the most obvious difference. 304 stainless steel pipes for food must have a BA-grade surface, which is a bright surface; industrial pipes have no surface requirements, but the surface is often rough, and the key is corrosion resistance.

3. Requirements for processes

When food-grade 304 stainless steel pipes are in direct contact with food, the inside finish is extremely important. The inner wall needs to be polished and brightly annealed to make the tube wall smoother. Clogging can be prevented if there is a liquid medium inside.

Since industrial pipes are usually used in polluted environments, they have higher requirements for anti-oxidation performance, so pickling passivation treatment is generally used. During pickling passivation, a thick oxide film is generated on the pipe’s surface, which improves corrosion resistance.

4. Standards for implementation

The reference standard for food grade 304 stainless steel pipe is QB/T 2467-2017 “Stainless Steel Pipe Standard for Food Industry”

It is not very similar to the standards for implementing stainless steel pipe and industrial pipe. Stainless steel specifications offer a lot more flexibility when it comes to wall thickness and thickness range. As for industrial pipes, there is little flexibility and no standard for wall thickness or thickness range. We need standardized specifications on these types of pipes that can be used by all manufacturers who produce them in order to help manufacturers implement these standards. Stainless steel pipe and industrial pipe standards are changing. Technology, materials, and manufacturing processes have been updated to meet the new standards.
