Stainless steel pipe with surface silanization passivation treatment
Stainless steel pipe with surface silanization passivation treatment Details:

The silane passivation process has the advantages of no pollution, simple process and low cost. On the surface morphology and composition of the silane film, it was found that a dense and smooth silane film was formed on the metal surface. The corrosion resistance of the BTESPT silane film was analyzed and compared by the salt water immersion test and the acid-base immersion test. It was found that the corrosion resistance of the 40Cr covered by the BTESPT silane film has been greatly improved, and the corrosion resistance of the film can even be comparable to that of the zinc phosphate film. Comparable. The corrosion durability test of the silane film was carried out, and it was found that the 40Cr sample treated with BTESPT silane solution was an anode-controlled corrosion polarization process, and the silane film protective matrix was mainly physical protection. In order to further improve the corrosion resistance of the silane film.


Gas chromatographic quantitative tubes, chromatographic columns, and gas pipes have low sample adsorption, small dead volume, good reproducibility, and stability and reliability in the analysis. It has been fully verified in the analysis of non-methane total hydrocarbons, benzene series, and sulfides.

Specification: 1/16, 1/8
Application: chromatographic column, loop tube, gas pipe
