In recent years in the field of semiconductor production-use chemicals, water and gas handling, as well as in the biochemical, pharmaceutical and medical equipment fields, there has been a rapid growth in the demand for piping and tank interiors with special features such as smoothly polished interior surfaces with no foreign matter attachment and with high corrosion resistance.

In order to satisfy such demands, Abel applies electro-polishing and chemical polishing to the interior surfaces of stainless steel pipes and tanks.

In particular, we have developed our own original technology for polishing the interior of three-dimensional piping. And for products made from flexible materials that are difficult to treat using electro-polishing, we have developed chemical polishing methods. In the final process, precision cleaning, the products are rinsed in pure water under class 1,000 clean room conditions, then dried in clean air or nitrogen gas, checked for residual foreign matter contamination using a white globe test and finally packed.

In addition, we carry out spectrometer inspections to check for residual ions and residual oil according to necessity.

Super Black is an electrolytic color development method that makes the immobile film existing on stainless steel surface develop electrochemically without changing o affecting the ground bed.

Stainless steel processing can include bending, cutting and welding. When stainless steel that has undergone such processes is color developed using conventional chemical methods, some color loss and irregular coloring are bound to occur on the processed sections.

Super Black is a color development method that can overcome these problems to provide an even more uniform finish and give highly superior functionality to stainless steel, while at the same time maintaining all the benefits of conventional color development methods.

In the same way, Lamina Color develops the surface oxide film to achieve beautiful color tones while maintaining stainless steel’s metallic sheen as it is. In addition, the resulting color doesn’t peel off or change even over an extended period of ten years or more.

Furthermore, besides allowing even sharper and darker colors to be achieved, Super Black and Lumina Color also cut down on color differences that occur between different lots of the same product, which is a major drawback of conventional methods.
