क्रिम्प फिटिंग क्या होती हैं?
ए क्रिम्प फिटिंग is a permanent hydraulic coupling. It mainly consists of a fitting body, nut, and sleeve, and through a crimping process, the fitting is tightly connected to the pipeline, achieving a reliable seal and a secure connection. It is widely used in many fields such as petrochemicals, machinery manufacturing, automotive industry, and aerospace.
They are attached by placing the fitting over the end of a hydraulic hose, and then crimping the fitting to the hose with a crimping machine. The crimping machine applies pressure evenly around the base of the fitting, resulting in a strong seal between the hydraulic fitting and hydraulic hose. There are long teeth on the hose which, under pressure, attach to the crimp fitting and result in a more durable seal that is suitable for high pressure applications.
Crimp Fitting Type
Crimping fittings come in various common types.
Straight crimp fittings have a simple structure and are used to connect two pipes on the same straight line, allowing the medium to flow in a straight line. They are widely used in various piping systems.
Elbow crimp fittings have different bending angles, such as 45 degrees and 90 degrees, which can change the flow direction of the medium in the pipe. They are suitable for pipe installations with special spatial requirements, such as connecting pipes in corners or narrow spaces.
T crimp fittings can connect one pipe to two other pipes. They are divided into equal tees and reducing tees. Equal tees have three ports with the same diameter and are suitable for branch pipes with the same diameter; reducing tees have different port diameters to meet the needs of branch pipes with different diameters and are often used in piping systems that require flow splitting or merging.
Four-way crimp fittings can achieve multi-directional pipe connections and play a role in more complex piping networks, allowing the medium to be transported and distributed in multiple directions.
In addition, there are some special types of crimp fittings, such as crimp fittings with flanges, which can be used to connect with other equipment or pipes with flanges, facilitating installation and disassembly.
Crimped Hose Fitting Specifications
Specifications typically include the fitting's diameter, the material of the connection joint, and the operating pressure.
First, crimped hose fitting specifications usually include the diameter. Common diameters include 1/4 inch, 3/8 inch, and 1/2 inch, with the specific size depending on the pipe dimensions and the diameter of the hose to be connected.
Second, specifications also include the material of the connection joint. Common materials include stainless steel, copper, and aluminum. Different materials are suitable for different working environments and media.
Furthermore, specifications also involve the operating pressure. Different models of crimped hose fittings can withstand different maximum pressures, requiring the selection of the appropriate specification based on specific operating pressure requirements.
In summary, crimped hose fitting specifications are determined by parameters such as diameter, material, and operating pressure. Choosing the appropriate specification ensures a safe and reliable connection while meeting the requirements of the working environment and media. Hopefully, this information will help you better understand crimped hose fitting specifications.
Hydraulic Hose Fittings and Crimping Methods
1. Hose Outer Cover Skiving: A certain length of the outer rubber layer must be removed during crimping. Suitable for steel wire braided hoses and steel wire spiral hoses conforming to GB/T3683-92, GB/T 10544-03, DIN20022, SAE100R1A/R2A standards.
2. No outer cover skiving is required, simplifying the crimping process. Suitable for fiber braided hoses and steel wire braided hoses such as SAE100RIAT/R2AT.
3. For skive-type crimping, a specified length of both the inner tube and outer cover must be removed. This design is referred to as an inner-lock, safety-type crimped hose fitting. Suitable for large-diameter pipes such as GB/T10544-89, SAER12, and ultra-high pressure steel wire spiral hoses such as DIN20023-4SH.
Crimping Fittings Installation Method
When installing crimp fittings, strict adherence to relevant installation specifications and standards is required. First, ensure the pipe surface is flat and clean to avoid affecting the connection's sealing. Second, select the appropriate crimp fitting size and model based on the different pipe dimensions and pressure requirements. Finally, use the necessary tools and techniques for installation and commissioning to ensure the quality and stability of the connection.
Place the fitting over the end of the hydraulic hose, then use a क्रिम्पिंग मशीन to tighten the fitting onto the hose. The crimping machine applies even pressure to the bottom of the fitting, creating a strong seal between the hydraulic fitting and the hydraulic hose. The hose has long teeth that engage with the crimp fitting under pressure, forming a more durable seal, suitable for high-pressure applications.
