KXT Rubber Expansion Joint Single Ball

Product Data

Product Introduction

KXT rubber expansion joint is a pipe connection fitting, which is usually used for vibration absorption, noise reduction and deformation compensation in the pipeline system. It is made of rubber and has good flexibility and elasticity, which can play roles such as buffering, shock absorption, noise reduction, and displacement compensation in pipeline systems.

KXT rubber expansion joint are divided into various types, including single sphere, double sphere, reducing, limiting, axial moving, etc. Different types of rubber expansion joint are suitable for different occasions and pipeline systems.

The following are the size ranges of some common KXT single sphere rubber expansion joint for your reference:

• DN30 (1 1/4 inches) to DN3000 (12 inches)
• Working pressure: 10 bar (145 PSI) to 25 bar (363 PSI)

KXT rubber expansion joint has the characteristics of simple installation, convenient maintenance, long service life, etc., and is widely used in pipeline systems in the fields of construction, municipal, petroleum, chemical, power, etc.

When using double ball rubber joint, KXT rubber expansion joint uses explosion-proof ring and is equipped with a limiting device, which can effectively prevent the danger of double ball rubber joint bursting during use. In addition, we also suggest that if single ball rubber joints can be used, double ball rubber joints should be avoided as much as possible, as although the material of double ball rubber joints and single ball rubber joints is the same, there is still a risk of explosion due to the length of the rubber. The term 'curing' is widely used throughout the rubber industry and holds an important position in rubber chemistry.

The vulcanization of KXT rubber expansion joint rubber is a kind of product that converts basically plastic raw rubber into dimensional stable product through chemical crosslinking between rubber molecules. The physical properties of vulcanized rubber are stable and the use temperature range is expanded. The vulcanization (crosslinking) reaction ability between rubber molecular chains depends on their structure. Unsaturated diene rubber (such as natural rubber, styrene butadiene rubber, nitrile butadiene rubber, etc.) contains unsaturated double bonds in its molecular chain, which can form intermolecular crosslinking with sulfur, phenolic resin, organic peroxide, etc. through substitution or addition reaction. Saturated rubber is generally cross-linked with free radicals with a certain amount of energy (such as organic peroxides) and high-energy radiation.

The rubber containing special functional groups (such as chlorosulfonated polyethylene, etc.) in the KXT rubber expansion joint is linked with the specific reaction of the given substance through various functional groups, for example, the sulfenamide group in the rubber is cross-linked through the reaction with metal oxides and amines. The KST-L threaded rubber joint sphere is composed of an inner rubber layer, a reinforcing layer with multiple layers of scraped nylon cord fabric, and a composite rubber tube with an outer rubber layer. The rubber materials used vary depending on the medium, including natural rubber, styrene butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, chloroprene rubber, silicone rubber, fluorine rubber, and so on. Product Usage: The connection between threaded rubber joints and pumps and valves, especially suitable for pipelines with high vibration and frequent changes in temperature and cold.
