Single Sphere Full Face Rubber Flexible Expansion Joint

Product Data

Product Introduction

Full face seal single ball rubber expansion joint is an elastic element used for pipeline connection, usually composed of inner and outer rubber materials and steel wire rings. It can compensate for displacement and deformation caused by temperature changes, pipeline vibrations, and earthquakes in the pipeline system.

The spherical part of this joint is usually made of rubber, which has certain compressibility and flexibility, and can withstand the vibration and displacement in the pipeline system. The steel wire ring is used to strengthen the structural strength of the joint and prevent it from excessive stretching or cracking.

Full plane sealed single ball rubber expansion joints have wear resistance, corrosion resistance, and high temperature resistance, and can be applied in various industrial fields, such as pipeline systems in chemical, petroleum, natural gas, water supply, drainage, and other fields. They are easy to install, maintain, and replace, and can extend the service life of pipeline systems, reducing the cost of system maintenance and repair.

The data parameters of the full plane sealed single ball rubber expansion joint generally need to be selected based on specific circumstances. Here are some common parameters:

Pressure level: Generally able to withstand pressures ranging from 10KPa to 2.5MPa.
Diameter: Different specifications can be selected based on the size of the pipeline, generally ranging from DN32 to DN3200.
Applicable medium: Suitable for various media such as water, oil, gas, etc.
Applicable temperature range: usually suitable for the temperature range of -40 ℃ to+120 ℃.
Tensile strength: generally between 2MPa and 15MPa.
Compression deformation: generally between 10% and 25%.
Shockproof performance: Can withstand frequencies from 10Hz to 50Hz, with an amplitude of 2mm.
