Large diameter thick wall expansion joint

Product Introduction

Large-diameter thick-walled expansion joint is an important industrial component with wide applications. The following is its detailed introduction:

Definition

Large diameter thick wall expansion joint is a kind of elastic compensation element used for the connection between equipment and equipment. Its large diameter and relatively thick wall can play an important role in many working conditions.

Moulding mode

Two ways of integral molding and welding molding.

Characteristics

1. Wall thickness, high rigidity and high strength: Can withstand larger pressure and external force to ensure stability and reliability under complex working conditions.

        2. Small compensation amountGenerally, only 1-2 waves are needed to meet the compensation requirements of axial displacement of the equipment itself.

        3. Optimize the stress condition of the equipment: Using single-wave thick-wall expansion to save energy, the equipment is not affected by the blind plate force generated by internal pressure, and the equipment is easier to fix.

Action

        1. Compensation for thermal expansion: It can compensate the thermal expansion of pipelines between equipment due to temperature changes, and prevent the damage of pipelines due to thermal expansion and contraction.

        2. Reduce the influence of installation error: Reduce the force caused by installation error on the equipment, and facilitate the installation and debugging of the equipment.

        3. Absorb axial displacement: It is mainly used to compensate the axial displacement of the equipment itself, and is mostly used for the thermal compensation deformation of the container cylinder itself.

Fields of application

It is suitable for boilers and pressure vessels, as well as scenarios such as shell, vessel and pipeline compensation with high strength requirements and small compensation. It is also widely used in steel, electric power, petroleum, chemical industry, metallurgy, environmental protection and other industries, and plays a role in pipeline compensation of exhaust, ventilation, ventilation, smoke and dust, waste gas treatment and other systems.

  ; Precautions for Use

During the operation of the pipeline equipped with expansion joints, the valve should be opened and closed gradually, so as to avoid sharp changes in temperature and pressure in the pipeline, which can cause damage to the support or expansion joint.
