When should hydraulic fittings be used

Steel pipes are usually used as fluid conductors, especially when a large amount of fluid is moved, or when considering the cost related to the use of pipes, the basic hydraulic circuit adopts seamless carbon steel pipes. When selecting the pipes used in the circuit, it is important to pay attention to the details, and all pipes shall be free of any dust, rust and all residues left in the manufacturing process. What will be introduced today Hydraulic fittings should be used.

Because steel is easy to rust, the pipeline has a standard paint surface to protect the metal surface, especially during transportation and storage, this process is called "black iron pipeline". Only the pipeline that has been pickled, oiled or pickled is the facing that the hydraulic system pipeline should choose.

When sizing pipes, it should be remembered that "nominal pipe size" (NPS) is the system used, for pipes under 30 cm, the inner diameter is smaller than the outer diameter, for example, a 13 cm pipe, the outer diameter is 14 cm.

Each pipe size has a different wall thickness. Since the specified outer diameter is standard and remains unchanged, the thicker wall thickness will change the inner diameter of the pipe. When selecting the pipe for a specific application, the wall thickness must be considered to allow proper fluid flow.
