Description

1. Expansion joints(compensators)

  • Introduction

Expansion joints, also known as compensators, utilize flexible bellows to compensate for stresses in pipelines and vessels due to temperature changes and vibrations. They can handle dimensional changes caused by thermal expansion/contraction and axial/lateral/angular displacements. They also reduce noise and vibrations, especially in heating systems. Placed on heating pipelines, compensators absorb thermal expansion, relieving stress on pipe walls and structures. These elastic components are reliable, compact, and widely used in chemical, metallurgy, and nuclear industries. Vessel expansion joints are commonly U-shaped, while pipeline joints are classified as universal, pressure balanced, hinged, or gimbal types.

  • Classification

Main Item Classification Description

Metal Expansion Joint

Elbow Expansion Joint

Bend the pipe into a U-shaped or other shape, also known as tension bends,are a type of expansion joint that utilizes the elastic deformation ability of the form to compensate. Its advantages are good strength, long service life, and on-site production.The disadvantages are space-consuming, high steel consumption, and high friction resistance. This type of expansion joint is widely used in various steam piping and long pipes.

Bellows Expansion Joint

A bellows expansion joint is an expansion joint made of metal bellows. It can expand and contract along the axial direction of the pipeline, and also allows a small amount of bending. In order to prevent exceeding the allowable compensation amount, protective rods or rings are installed at both ends of the bellows, and guide supports are installed on both ends of the connected pipelines. There are also angular and lateral expansion joints, which can be used to compensate for rotational deformations and lateral deformations of pipelines. The advantages of these expansion joints are space-saving, material-saving, easy standardization, and mass production, but the disadvantage is the relatively short lifespan. Bellows expansion joints are generally used in short pipelines with low temperature and pressure. With the improvement of bellows production technology, the application scope of this type of expansion joint is expanding. Currently, bellows expansion joints can be used in pipe systems with a maximum pressure of 6.0 MPa.

Slip-Type Expansion Joint

The slip-type expansion joint has inner and outer sleeves that move axially relative to each other, sealed with a stuffing box. It's designed to maintain axial alignment of pipe ends and compensate for axial expansion and rotation. Made of sleeves, shells, and sealing materials, it's compact yet provides significant compensation, ideal for hot water, steam, and grease applications. Using a self-sealing dynamic seal, it accommodates pipeline movement and ensures leak-free operation, even at high temperatures of up to 350 degrees Celsius.

Non-metallic Expansion Joint

Rubber Expansion Joint

Composed of rubber and rubber-fiber composite materials, steel flanges, sleeves, and insulation materials, it is mainly used for flexible connections between various fans and ducts. Its functions include shock absorption, noise reduction, sealing, medium resistance, easy displacement and installation. It is an ideal accessory for shock absorption, noise reduction, smoke and dust removal in the field of environmental protection.

Fabric Expansion Joint

The fabric expansion joint is mainly made of fiber fabric, rubber, and other high temperature resistant materials. It can compensate for the vibration and deformation of fans and ducts.Fabric expansion joints can compensate for axial, lateral, and angular products, with features such as no thrust, simplified support design, corrosion resistance, high temperature resistance, noise reduction, vibration reduction,and others.It is particularly suitable for hot blast pipes and smoke and dust pipeline of power plant.The non-metallic compensator's fiber fabric and insulation cotton itself have the functions of sound absorption and vibration isolation, therefore they can effectively reducing the noise and vibration of boiler, fan, and other systems. Simple structure, light weight, and easy maintenance.

2. Non-metallic Expansion joints

  • Non-metallic compensators/expansion joint types

Non-metallic compensators can be divided into the following types: straight cylindrical non-metallic expansion joints, compound non-metallic expansion joints, angular non-metallic expansion joints, and square non-metallic expansion joints.

Rectangular non-metallic compensators are mainly used in flue ducts of power plants to absorb thermal displacement and/or shock absorption. The connection types for rectangular non-metallic compensators include flange connection and nozzle connection.

  • Common structural types of non-metallic compensators (non-metallic expansion joints) include the following six:
