Therefore, the design and construction of quick couplings must consider a variety of factors and operating conditions to ensure a complete product line with high quality and high safety throughout the process.
A key issue in the manufacture of quick couplings is to assess their exposure to corrosion. From an environment where damage occurs very slowly to an environment where the process is particularly violent and rapid, the increasing damage of this kind of component varies according to the application environment.
Some general conditions can be determined:
Low corrosion: Without special environmental conditions, if the hydraulic oil used is kept pollution-free, it will not cause damage to the circuit;
Medium corrosion: related to the fluid used, such as in the cooling system using water-based solutions;
High corrosion: Under these conditions, quick couplings must be able to withstand harsh environments, such as offshore oil platforms.
Three kinds of materials are mainly used to make quick joints to meet these different conditions:
Carbon steel: This is the most widely used metal in quick couplings. It provides a good balance between technical and commercial characteristics and performs well in low-corrosion applications;
Brass: Easy to handle, good resistance to medium corrosive liquids.
Stainless steel: This material is widely used in daily life, but in the field of quick couplings, it is mainly used for high corrosion applications. It is extremely wear-resistant and durable, and is recommended for shipbuilding and offshore platform industries.
