Is It Useful To Treat Waste Sulfuric Acid With Tantalum Tubes?

The tantalum tube has very important application value to treat industrially discarded sulfuric acid.

In the middle of the last century, western countries produced tantalum evaporators for the concentration of sulfuric acid. my country designed and manufactured the first tantalum evaporator for sulfuric acid concentration in 1985, and many more have been put into industrial applications since then. Waste sulfuric acid has always been an important part of industrial waste, so its recovery is one of the important links in resources.

The key instrument for waste sulfuric acid treatment is the evaporator pipeline, and its pipeline system must have excellent corrosion resistance and high temperature resistance. Studies have shown that metal materials containing tantalum have excellent performance in corrosion resistance and heat resistance in organic media such as sulfuric acid, nitric acid, and hydrochloric acid. And it has good weldability and conductivity, and is an advanced new material for making industrial anti-corrosion equipment.

Now, by improving the process of boring the inner hole of the extruded tube blank, the extruded tube blank is realized without interruption, and the long extruded tube blank is used to produce a long tantalum tube with a diameter of 25x0.9x11000mm, which reduces the length of the cutting head and tail of the tube and improves the performance of the tube. Pipe yield. When determining the size of the previous tube blank of the finished tube, the maximum charging length of the LD30 mill, the degree of deformation of the tantalum material and the ratio of the diameter reduction to the wall reduction should be comprehensively considered.

At present, tantalum tubes are often used to make tantalum evaporators in tubular and coil types. The length of a single tantalum tube in the tubular type is about 3300 mm. Usually requires more than 4000 mm.
