Steel wire braided rubber hose, as a high-performance and multi-purpose industrial pipeline, is widely used in various fields such as hydraulic systems, petrochemicals, and mechanical manufacturing. Its unique steel wire weaving structure not only endows the rubber hose with excellent pressure resistance and tensile strength, but also ensures its stability and durability under complex working conditions. However, the connection sealing method is directly related to the safe operation and performance of the entire system. This article will elaborate on the connection and sealing methods of steel wire braided rubber hoses from three aspects: preparation before connection, precautions during connection process, and evaluation of sealing effect.

1、 Preparation before connection

1. Material selection and inspection

Before connecting steel wire braided rubber hoses, it is necessary to ensure that the selected connectors (such as joints, sealing rings, etc.) match the specifications of the hose and comply with the requirements of relevant standards (such as GB/T, JB/T, etc.). At the same time, the rubber hose should be carefully inspected to confirm that there are no cracks, scratches or other defects on its surface, and that the steel wire layer is not loose or broken, in order to ensure the integrity and reliability of the rubber hose.

2. Prepare workbench and tools

Choose a clean and flat workbench, and prepare the necessary tools and equipment such as cutting machines, glue peelers, sandpaper, measuring tools, sealant, etc. Ensure that all tools are in good condition for smooth subsequent operations.

3. Cutting and pre-processing

Use a cutting machine to accurately cut the steel wire braided rubber hose to the required length, paying attention to keeping the cut flat. Subsequently, use a rubber stripper to strip off a section of the outer rubber layer at both ends of the hose, exposing the steel wire layer. When peeling the adhesive, be careful not to damage the steel wire layer to avoid affecting the connection strength. After peeling the adhesive, use sandpaper to polish the steel wire layer and inner adhesive layer to remove burrs and impurities, and improve the sealing effect.

2、 Precautions during the connection process

1. Selection and installation of sealing rings

Select the appropriate sealing ring according to the specifications and connection requirements of the hose. The sealing ring should have good elasticity and oil resistance to ensure that it can maintain sealing performance under harsh working conditions such as high pressure and high temperature. When installing the sealing ring, it should be ensured that it is completely embedded in the joint groove without distortion or deformation. At the same time, pay attention to the directionality of the sealing ring to avoid installation errors that may cause leaks.

2. Installation and fastening of joints

Insert both ends of the processed rubber hose into the corresponding joints to ensure a tight fit between the hose and the joints. For joints that require locking, appropriate tools (such as wrenches, torque wrenches, etc.) should be used to tighten them according to the specified torque value. During the fastening process, excessive force should be avoided to avoid damaging the hose or joint. At the same time, pay attention to checking the fit between the joint and the hose to ensure that there are no looseness, gaps, or other phenomena.

3. Treatment of Steel Wire Braided Layer

For steel wire braided rubber hoses, the treatment of the steel wire layer is also one of the key links in connecting and sealing. During the connection process, it should be ensured that the steel wire layer is not excessively stretched or compressed to avoid affecting the performance of the hose. For certain special structural joints (such as sleeve type joints), it may be necessary to use specialized tools to fix the steel wire layer on the joint to enhance the stability and sealing of the connection.

3、 Evaluation of sealing effect

1. Appearance inspection

After the connection is completed, conduct a visual inspection. Observe whether the fit between the joint and the hose is good, and whether there are any looseness, gaps, or other phenomena; Check if the sealing ring is installed properly and undamaged; Check whether the steel wire layer is neat and free of disorder.

2. Stress testing

Conducting pressure testing is one of the important means to evaluate sealing effectiveness, and setting appropriate test pressure values based on the system's working pressure requirements. Place the connected hose assembly on the pressure testing bench for pressure testing and observe if there is any leakage. If there is a leak, the cause should be promptly identified and dealt with.

3. Durability testing

For steel wire braided rubber hose connection seals that require long-term use, durability testing should also be conducted. By simulating factors such as temperature, pressure, and vibration under actual working conditions, long-term operation tests are conducted on the connecting seals to evaluate their reliability and stability in practical use.

The connection and sealing method of steel wire braided rubber hose involves multiple links and details, which require strict adherence to relevant standards and specifications in practical operation. By selecting materials reasonably, preparing carefully, operating meticulously, and conducting rigorous testing and evaluation, the reliability and stability of the connection and sealing of steel wire braided rubber hose can be ensured, thereby guaranteeing the safe operation and performance of the entire system.
