Concertina is a wire made of galvanized steel. Designed with strong blades that cannot be cut and broken easily so we can say that if someone tries it it will take several minutes and they will need a special tool, we can also add that they expand like an accordion. The main function of[…]

Let's talk about galvanized steel. This is a type of steel processed with a treatment at the end of which it is covered with several layers of zinc. These layers of zinc protect the steel by preventing it from rusting. Galvanized steel is also a material with a more durable, scratch-resistant finish that is more attractive to many[…]

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[…]

There are different chemical substances in the industry that can cause corrosion in your facilities. Many times we are unaware that there are effective solutions to prevent corrosion of our piping systems, such as internal coatings. In this article we explain what are some of the highly corrosive substances that can damage your equipment and cause[…]

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,[…]
