Steel couplings

Two basic standards, i.e. DIN and ANSI, are applied in current projects in the power, gas, chemical, and oil industries. The former is more and more often replaced by EN standards.
The DIN norm is based on the studies of the German Institute for Normalisation (Deutsches Institut für Normung), and ANSI is based on the studies of the American National Standards Institute.
