Product Description

The withholding type hydraulic joint
is an important connecting component used
to connect high-pressure oil pipes and
other components in the hydraulic system.
The following is a detailed introduction for you:

 

 

 

Internal thread buckle straight head(A)

Joint body:
It can be inserted inside the hydraulic pipe and is the core part of the connection. It plays the role of conducting the hydraulic medium and connecting other components.

Sleeve:
It is placed on the outside of the hydraulic pipe and cooperates with the main body of the joint to clamp the hydraulic pipe during the crimping process to enhance the firmness of the connection.

Nut:
 Usually connected to the main body of the joint through threads, it is used to further fix the joint with other pipes or components. Some nuts also have anti-loosening designs, such as adding tightening knobs, etc.

Detailed data is required for customized finished hoses on demand.

Dimensional parameters
inner diameter:
accurate to millimeters or even 0.1 mm. It determines the flow rate of the fluid inside the hose. If it is too small, it will cause a large flow resistance and affect the system efficiency; if it is too large, it may not be able to adapt to the joints or devices connected to it. . For example, the inner diameter deviation of the hose that transports oil in a hydraulic system will directly interfere with the stability of oil pressure transmission.

Outer diameter:
It is related to whether the hose can be successfully installed into the established slot, bracket, or adapted to the external protective sleeve and clamping device. The outer diameter size is inaccurate and it is easy to be too loose or too tight during subsequent assembly. .

Length:
The total length of the customized hose needs to be given. Accurate to centimeters can meet most needs. If the application scenario has strict restrictions on hose extension and bending, a more accurate millimeter-level measurement value will be better, such as hydraulic pressure on an automated robotic arm. A slight deviation in the length of the hose may cause the movement to be blocked. 

Ball head size:
The diameter of the ball head must be clear, because it involves the fit with the corresponding interface. Excessive error will cause gaps and cause leakage; at the same time, the neck length and diameter of the ball head must also be informed, which affects the connection. Stability and flexibility, for example, the hose ball heads connected to some high-pressure ball valves cannot fit perfectly if the specifications are incorrect.
Performance Indicators

Pressure resistance level:
Specify the maximum working pressure that the hose needs to withstand. The unit is commonly used in megapascals (MPa). For example, hoses transporting high-pressure liquids in the petrochemical industry. Insufficient pressure resistance can easily lead to the risk of pipe explosion, so precise values are important for determining material selection and manufacturing processes. Very critical.

Temperature resistance range:
Gives the minimum and maximum temperatures that the hose will be exposed to. For example, the hose in the engine compartment of a car must withstand high temperature environments, while the hose for cold chain logistics transportation must maintain elasticity and sealing at low temperatures, otherwise it will Failure conditions such as hardening and brittleness may occur.

Chemical resistance:
Inform the type of chemical substances that the hose may be exposed to, whether it is strong acid, strong alkali, or organic solvent. Different chemical substances have different corrosive effects on the hose material. This data is essential for customizing hoses in the chemical and pharmaceutical industries.

Bending radius:
The hose will need to be bent during installation and use. Please indicate the minimum bending radius value to ensure that the customized product will not damage the internal structure due to excessive bending, resulting in poor fluid transportation, such as hoses at the joints of industrial robots.
Material Preferences

Hose main material:
Commonly used are natural rubber, nitrile rubber, EPDM rubber, etc. Natural rubber has good elasticity but poor oil resistance; nitrile rubber is oil-resistant and wear-resistant, and is often used for oil transportation; EPDM Propylene rubber has strong aging resistance and weather resistance, and is suitable for long-term outdoor use. Choosing the right material according to the application scenario can extend the service life.

Ball head material:
Metal materials are available, such as stainless steel ball heads, which are corrosion-resistant and high-strength; there are also plastic ball heads, which are lower in cost and light in weight. The choice is based on the pressure and corrosion conditions of the usage scenario.Reinforcement layer material (if any): Some high-pressure hoses are equipped with steel wire, fiber and other reinforcement layers to improve the pressure-bearing capacity. It indicates that it is steel wire braid reinforcement, steel wire
wind

Usage environment details
installation space restrictions:
Describe the specific spatial form of the hose installation, whether it is in a narrow pipe or in an open space; whether there are corners or obstacles. These space constraints will affect the shape design of the hose, such as hoses in restricted spaces under mines. Layout/Vibration and impact conditions: Inform whether the hose is used in an environment with frequent vibration and vulnerability to impact, such as the hose on a construction pile driver. Under such working conditions, the anti-vibration and impact-resistant structure of the hose must be strengthened to avoid premature breakage.

Frequency of use:
Indicate whether the hose is used continuously for a long time, or is used intermittently and occasionally. Hose used frequently has higher requirements for the wear resistance and fatigue resistance of the material
