Company History

Our company was founded in the seventies by Mr. Hubert Skibowski as a planning office in Hamburg. Following the technical possibilities and the market requirements, the planning office became a company specializing in the development and production of pigging systems. The focus was on the lubricating oil and chemical industries, although many systems for the food and paint industries were also successfully developed.

Today I.S.T. is one of the leading companies for industrial pigging technology.


Hubert Skibowski, founder of the company was engaged by Oelwerke J. Schindler to develop a new cleaning system resulting in the development of first closed pigging system with the first duplex pig.
