Related information about steel tube for pharmaceutical use

1. Material requirements of steel tube In the pharmaceutical field, the material of steel pipes needs to meet strict standards. 

Corrosion resistance: Since the pharmaceutical process may be exposed to various chemicals, including acidic, alkaline or corrosive pharmaceutical ingredients, steel tube need to have good corrosion resistance. For example, some alloy steel tube or composite steel tube may be more suitable because they are better at resisting corrosion.

Purity: The material of the steel tube must be pure to avoid contamination of the medicine. Impurity levels need to be strictly controlled to ensure the quality and safety of pharmaceuticals. If carbon structural steel tube can meet purity requirements, they can also be used in certain aspects of pharmaceuticals, such as some transportation pipelines that are not in direct contact with pharmaceuticals. However, quality control during the production process must be ensured to prevent the mixing of impurities.

2. Types of steel tube

Seamless steel tube:

Advantages: Since seamless steel tube have no welds, there is less risk of leakage when transporting fluids, and the inner wall is smooth, which can reduce fluid resistance, which is very important for fluid transport in the pharmaceutical process, such as the transport of liquid medicine. In some pharmaceutical processes that require extremely high cleanliness, seamless steel tube can better ensure the purity of drugs and avoid contamination of drugs during transportation.

Application scenario: It can be used to transport high-purity medicinal liquids, distilled water and some pharmaceutical raw materials that require strict hygienic conditions. For example, in a workshop that produces injections, from raw material preparation to finished product filling, if steel tube are used for transportation, seamless steel tube would be a better choice.

Welded steel pipe:

Advantages: The production efficiency of welded steel pipes is relatively high and the cost is low. It may be used in some pharmaceutical auxiliary links that do not have particularly high pressure requirements and have special requirements for the corrosion resistance and other properties of steel pipes.

Application scenarios: For example, in the wastewater treatment system of a pharmaceutical factory, it is used to transport some wastewater that has undergone preliminary treatment and has slightly lower purity requirements for steel pipes, or is used to transport air in some ventilation systems.

3. Steel tube standards

Hygiene standards: Steel tube for pharmaceutical use must meet strict hygiene standards. The internal surface of the steel pipe must be smooth and easy to clean and disinfect to prevent the growth of bacteria and microorganisms. For example, the inner surface roughness of the steel tube must be controlled within a certain range to prevent the residual liquid from breeding bacteria and affecting the quality of the medicine.

Quality standards: Strength, toughness and other mechanical properties must also meet the requirements for use in the pharmaceutical process. For example, in some pharmaceutical liquid transportation pipelines that need to withstand a certain pressure, the steel pipes need to have sufficient strength to ensure that the pipelines will not rupture, thereby avoiding pharmaceutical leakage and production accidents. For example, some steel tube in the GB/T8163-2008 (seamless steel tube for transporting fluids) standard can be used as fluid transport pipelines in pharmaceutical engineering. It has clear regulations on the dimensional accuracy, chemical composition, mechanical properties, etc. of the steel tube to ensure that they are Reliability in pharmaceutical applications.
