Metal bellows with carbon steel spray painted flange

Metal bellows with carbon steel spray painted flange

Metan bellows with carbon steel spray painted flange is also called carbon steel expansion joint, carbon steel spray painted bellows Pump Connectors.It is an elastic element composed of bellows body, carbon steel flange, limit lug and limit nut.Mainly used to compensate for axial displacement, which is the compensation for thermal expansion and relative motion in pipes, vessels and machines.According to different applications, we can produce carbon steel metal expansion joint with different requirements and different colors.For example, we can paint it red in fire pipes

Features: Shock absorption and noise reduction, easy to install, and different colors.

• NOMINAL DIAMETER: DN32mm-DN1000mm
• WORKING PRESSURE: 0.6-2.5Mpa
• WORKING TEMPERATURE: -15℃ to 300℃
• CONNECTION METHOD: flange type
• APPLICABLE MEDIUM: water, steam, air, weak acid and alkali, oil, etc.

PERFORMANCE

Advantage:

1. Compensate for axial, lateral and angular thermal deformation of the absorption pipe.
2. Absorb expansion of metal expansion joints, convenient for installation and disassembly of valve pipe.
3. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline.
4. Absorb the deformation of pipelines caused by earthquake and subsidence.

Application:

Metal bellows expansion joints are used in a variety of applications and can be used over a range of temperature requirements, pressures and sizes.
The corrugated compensator uses the telescopic and offset of its main elastic component bellows to compensate the displacement of the pipeline, with large compensation and good elasticity. The product is suitable for conveying seawater, fresh water, hot and cold water, drinking water, domestic sewage, Crude oil, fuel oil, lubricating oil, refined oil, air, gas and other media.

Principle of axial movement of metal bellows expansion joint :

The metal bellows expansion joint is considered to be the elongation or compression of the pipe system on its longitudinal axis, which means that the total length of the expansion joint will be extended or compressed during the absorption movement.An axial expansion joint designed to absorb large motions can contain one, two or more bellows in one unit, and can also achieve greater motion by pretensioning or by installing multiple expansion joints on the pipe section.According to the nominal diameter and length,the axial expansion joints can absorb small lateral and angular deviations as well as mounting tolerances. However, we recommend the use of the main function that should limit the axial expansion joint, otherwise its service life may be adversely affected.

Purpose:

1) Pipeline has large deformation and limited deformation space.
2) Large-diameter pipes with large deformation and displacement and low pressure.
3) pipelines requiring high-frequency mechanical vibration absorption or isolation.
4) pipelines that need to absorb earthquake or foundation settlement.
5) pipeline pump outlet shock absorption.
