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.

Application
Hand wrapped bellows expansion joint rubber 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.
