How is stainless steel made for industrial stainless steel mix tanks?
The creation of the stainless steel that goes into stainless steel mix tanks involves a series of steps. The first step in the manufacturing of stainless steel is melting and casting. Intense heat is used to melt the materials that make up stainless steel and they are formed into casts of generic shapes: blooms, billets, slabs, rods, or tube rounds. This allows for the next step of forming to be done more easily. Forming is done using hot rolling and resulting in bars, wires, plates, strips, and sheets of stainless steel that are one step closer to being an actual mixer. Next, the stainless steel gets a heat treatment, also known as annealing. This process involves heating and cooling the formed material in a very controlled manner as a way to relieve internal stress. Depending on the type of stainless steel being made, the degree of heat and cool varies. After all of this, there will be a bit of build-up on the steel, which would ruin the functioning of the stainless steel mix tank. This build-up is removed using a descaling process. Following this important step, the stainless steel is cut into particularly sized pieces that will eventually be made to create the final mix tank. This can be accomplished through mechanical cutting, nibbling, flame cutting, or plasma jet cutting. Finally, the material must be finished. Adding a surface finish is very important to the functionality of a stainless steel mixer and creates a sanitary, polished, and beautiful product.
Mixing Equipment Services specializes in mixing tanks and blending systems to meet your exact requirements. The most popular agitated vessels we supply to the sanitary and biopharma markets:
- FDA HDPE – Polyethylene tanks for non-metallic / plastic vessel
- USP VI and FDA PP – Polypropylene, has FDA/USP VI for biopharma use, and non-metallic
- 316Lss, 20RA polish, electropolish, passivated – 316L (L grade 316) stainless steel is most common for biopharma, and for salt/saline applications in food/beverage. Note 304ss is common in food applications.
- Hast C – Hastelloy is available in C276 and C22 and a few B grades as well.
HDPE and PP are used extensively in the biotech industry. We would NOT suggest threaded ports or to use bulkhead fittings, but to use TC (Tri Clamp) sanitary welded ports. We would also suggest USP VI PP ball or diaphragm outlet valve and NOT PVC.
For cleaning we can make a vapor tight GMP style tanks in poly materials or pressure vessels in stainless and exotic alloys which can be spray ball cleaned with a CIP system. We also offer Ribo testing to validate full coverage with the spray balls.
