Hand Wrapped EPDM Expansion Rubber with DIN, ANSI, JIS Flange Type
Product Description
Hand wrapped EPDM expansion rubber is a flexible connector made of rubber as the main material, and the rubber layer and reinforcing fibers or steel wires are wrapped around the core mold layer by layer by hand, and made after vulcanization and molding. It is usually equipped with flanges or other connection structures at both ends, and is used for the connection between pipelines, equipments or containers.
Pressure resistance: through multi-layer winding and reinforcing materials, it can withstand high working pressure.
Corrosion resistance: the rubber material has good corrosion resistance to acid, alkali, salt and other media.
Vibration and noise reduction: it can effectively absorb the vibration and noise in the piping system and prolong the service life of the equipment.
Convenient installation: small volume, light weight, flexible installation, strong adaptability.
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.
