Product details


Products Description



 









 




The wide arch rubber expansion joint consists of four parts: inner lining layer, winding layer, outer lining layer, and flange. The inner lining layer is made of high-quality rubber material, the winding layer is made of nylon wire, and the outer lining layer is also made of rubber material. Flanges are customized according to the requirements of pipeline engineering, and common types include anti-corrosion, fireproof, and other types of flanges.‌

Performance characteristics



 



1.High flexibility



Make the size, shape, and thickness of the reinforcement layer of the joint according to the needs



2.Diversified reinforcement materials



Hand wound rubber joints can use a variety of reinforcement materials to provide the required mechanical strength and corrosion resistance.



3.High pressure bearing capacity



Manual winding can ensure the structural uniformity of the joint, thereby improving its pressure bearing capacity and overall strength.



4.Easy maintenance and replacement



Usually equipped with flanges or threaded interfaces for easy installation and replacement, reducing downtime of pipeline systems.

Note: If the medium is oil, acidic or alkaline substances, and there are special requirements for the working temperature, you can customize it by sending a letter or drawing. Please specify when ordering.



 





Production Flow



 



The processing flow of manually wide arch rubber expansion joints mainly includes the following steps:



1. Preparation work: Check the surface condition of each part of the joint to ensure that the surface is clean and undamaged. The connection surface between the joint and the flange should be coated with a release agent to prevent adhesion.



2. Glue application: Apply a layer of glue, then fix the inner lining and winding layer together, and then apply another layer of glue to fix the outer lining layer on the winding layer.



3. Winding: Wrap nylon thread at a certain angle until the required winding density is reached, and then undergo shaping treatment.



4. Curing: Place it in the curing chamber for heating and curing, usually for about 4 hours, depending on different materials and requirements.



 





Application



 



Wide arch rubber expansion joints play an important role in pipeline systems due to their excellent sealing and compressive properties. This type of joint can effectively absorb the vibration and displacement of pipelines, reduce noise, so it is widely used in pipeline systems in the fields of water supply and drainage, sewage treatment, chemical industry, petroleum, sanitation, etc.
