Metal bellows expansion joints

Khớp nối chống rung kim loại

Khái niệm: Khớp nối chống rung kim loại còn được gọi là ống thổi kim loại, khớp nối co giãn kim loại, hoặc Đầu nối bơm ống thổi. Khớp nối bao gồm ống thổi (một loại phần tử đàn hồi) và các ống cuối, giá đỡ, mặt bích, ống dẫn và các phụ kiện khác tạo thành phần chính của công trình. Khớp nối chống rung kim loại thuộc bộ phận bù. Khe co giãn kim loại chủ yếu được sử dụng để bù dịch chuyển trục và có khả năng bù dịch chuyển góc, nhưng nói chung nó không được sử dụng để bù dịch chuyển góc. Khớp nối co giãn nở kim loại là phần tử bù cho sự giãn nở nhiệt và chuyển động tương đối trong đường ống, tàu và máy móc. Hấp thụ dịch chuyển dọc trục, ngang và góc.

Metal bellows expansion joints are also called metal bellows, metal expansion joints, or bellows Pump Connectors. It consists of bellows (a kind of elastic element) and the end pipes, brackets, flanges, pipes and other accessories that form the main body of its work. The metal expansion joint belongs to a compensation element.The metal expansion joint is mainly used to compensate for axial displacement and has the ability to compensate for angular displacement, but it is generally not used to compensate for angular displacement. Metal expansion bellows are compensating elements for thermal expansion and relative motion in pipes, vessels and machines. Absorption of axial, lateral, and angular displacement.

Features: light weight, simple structure, convenient installation and maintenance, large compensation

• 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.

Performance:

1Compensation for installation error:Because the system error is inevitable during the pipeline connection process, the metal expansion joints better compensates for the installation error.
2 Good sealing performance: with a relatively perfect production and assembly system, metal expansion joint can ensure no leakage.
3 No reverse thrust: since the main material is metal bellows, the transfer is weak.The use of metal bellows expansion joint can simplify the design and avoid the use of large supports, saving a lot of materials and labor.
