SIESA PFA valves are corrosion resistant and guarantee zero leaks. They are highly recommended in the semiconductor, optoelectronics, pharmaceutical, food and beverage, petrochemical, refining, biochemical, cosmetics and high purity industries. What is PFA? Perfluoroalkoxy or PFA copolymers are a type of fluoropolymers with properties similar to polytetrafluoroethylene[…]

SIESA structural profiles provide the best performance in areas where other materials corrode causing structural failure and high maintenance costs. Pultruded structural profiles are a line of products manufactured in a variety of resin systems for industrial use. Pultruded profiles are: angles, channels, tubes and plates, all products[…]
Read moreValves are one of the most used pieces of equipment within different industries, but for their correct use you must know the desired use and the type of corrosive fluids. For which the SIESA Engineer must consider different factors to determine the ideal valve for their processes. The valves are the ones that[…]

Corrosion is an important industrial problem, as it can cause accidents (breakage of a piece) and, in addition, represents a significant cost, since it is estimated that five tons of steel in the world dissolve in a few seconds. What is corrosion? ? Corrosion is a chemical reaction (oxidation-reduction) in which three factors intervene: the pipe,[…]
Read moreWe recommend you read our article Permeation: An important factor when looking for coated pipe systems. This way you can learn more about this topic. Most of the factors affecting permeation are relatively simple and intuitive, others require a brief exploration of some more subtle aspects of the physical process in[…]
