Product Description

1.Introduction:

This product can be used for the soft joint, displacement compensation, vibration and noise lowering of metal pipeline to transport the liquid, air, solid, or other material, so it is a kind of new rubber vibration decrease product. Integrating into multi displacement of mechanical elasticity and flexible rubber joint of metal expansion piece, it can not only carry out free mechanical flexible in process of installation, dismantling and maintenance, but also can compensate the linear expansion and contraction caused by temperature change and non concentricity of pipeline caused by base descend and angle caused by other reasons. At the same time, it can eliminate the vibration and transmission of noise. Therefore, its application performance is excellent in meal expansion piece. It is a kind of multi-functional pipeline compensator.

 

2.Product Performance

Lanphan Rubber Flexbile Joints  are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces.

Rubber Flexbile Joints  is a single sphere design with less length, the supply range is from 32mm to 3600mm, and design pressure can be 1.0MPa/1.6MPa/2.5MPa, which is always used where low cost or space limitation control.

 

3.Application Range

Equipped with the excellent comprehensive performances of flexible rubber joint, Lanphan Rubber Flexbile Joints can be used for lift and transportation of raw water and sewage, transportation of water supply, cooling cycle water of thermal power plant, condensate water of metallurgy industry and chemical materials of chemical industries, cooling and dilution of oil and chemical industries and flexible connection of other industries. Lanphan Rubber Flexbile Joints is also suitable to transport all grain and powder material and gas for its high abrasive resistance.

In addition, special notifications are hereby conducted for design units and clients so as to ensure the project quality. Please note to install anti-break stop device, if Lanphan Rubber Flexbile Joints are designed to install close to pump exit nozzle and pipes’ corner. If your pipes need to be buried, please use our patent-buried protective devices. In a word, remark requirement for use, and we will provide satisfactory service to you.
