Experience 20 Year's of Wide Arch NBR Bellow Joints Rubber
Product Description
Wide arch NBR bellow joints rubber consists of four parts: inner lining layer, winding layer, outer lining layer, and flange. Experienced craftsmen use hand-winding technology to wrap the pre-treated rubber strips according to a specific angle and tension, layer by layer on top of the precision-designed molds, and each layer of winding needs to be precisely controlled to ensure that the thickness of the pipe wall is uniform and the corrugated structure is regular. This process not only tests the skill and patience of the craftsmen, but also gives the bellows unique mechanical properties and good flexibility.
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.
