Hydraulic fittings play a vital role in hydraulic systems as they join distinctive parts and preserve the proper drift of hydraulic fluid. Having information of how to understand the type of hydraulic fittings with the aid of yourself is critical for choice, preservation and replacement. This text will assist you navigate the system easily.
I. Basic Classification of Hydraulic Couplings
By Connection
(1) Welded Hydraulic Couplings: Connected to the pipe through welding.
(2) Ferrule Hydraulic Couplings: Fixed on the pipe using a ferrule to achieve connection.
(3) Flared Hydraulic Couplings: Connected tightly to the pipe through flaring.
By Material
(1) Stainless Steel Hydraulic Couplings: Corrosion-resistant, suitable for harsh environments.
(2) Carbon Steel Hydraulic Couplings: High strength, cost-effective, appropriate for typical working environments.
(3) Brass Hydraulic Couplings: Good conductivity, ideal for applications with special requirements.
II. How to Confirm the Type and Model of Hydraulic Couplings
Necessary Tools:
A caliper to measure thread diameter
A thread pitch gauge
A seat gauge to measure seat angle
First, determine if the thread is parallel or tapered. Tapered thread gets smaller towards the fitting end.
Second, for parallel thread, measure the diameter of the tops of thread, and for tapered thread, measures the diameter of the 5th thread from the end.
Then, identify the number of pitch per inch by placing the thread pitch gauge on the fitting thread.
Finally, if the connection end has angled cone or flared surface, determine the seat angle by using the seat gauge on the sealing surface.
III. Precautions
Make sure your hydraulic system is powered off and depressurized avoid accidents.
Be as precise as possible when measuring dimensions.
When replacing hydraulic couplings, try to use original equipment manufacture (OEM) parts to ensure the stability and safety of the hydraulic system. Jiayuan will be your trusted hydraulic fitting OEM provider.
