Hand Wrapped Bellows Expansion Joint Rubber with DIN, ANSI, JIS Flange Type
Product Description
Hand wrapped bellows expansion joint rubber is a kind of flexible pipe made by unique handmade craftsmanship, and its production process combines the essence of traditional skills and modern material science. Firstly, high quality rubber materials with high elasticity, aging resistance and corrosion resistance are selected, and through fine formulation and mixing, the base material of the pipe is ensured to have excellent physical properties and chemical stability.
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.
