BS 4504 Stainless Steel Compensator SS304 316L expansion joint axial motion bellows compensator joint

Product Introduction

The corrugated compensator consists of a pipe, a bellows, and a pair of hinges connected to the pipe. The corrugated compensator is a compensation device that uses the reasonable expansion and contraction deformation of its elastic elements to absorb the specification changes caused by thermal expansion and cold contraction of pipelines, conduits or containers, and belongs to a compensation component. Absorption of axial, lateral, and angular displacements.

Product Role

1. Compensate for the axial, transverse and angular cold and hot deformation of the absorption pipeline.
2. The expansion and contraction of the corrugated compensator is convenient for the installation and disassembly of the valve pipeline.
3. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline.
4. Absorb the deformation of the pipeline by earthquake and subsidence.

Product Advantages

1. Strong compensation ability: The corrugated compensator can absorb the thermal expansion and contraction, displacement and other deformations of the pipeline caused by temperature changes, medium flow or external pressure and other factors, so as to protect the stability and safety of the pipeline system.
2. Compact structure: Compared with other types of compensators, the structure of corrugated compensators is more compact and occupies less space, which is conducive to the overall layout and design of the pipeline system.
3. Strong corrosion resistance: Corrugated compensators are usually made of corrosion-resistant materials, such as stainless steel, alloy steel, etc., which can operate stably for a long time under harsh working conditions.
4. Long service life: Due to the excellent material and reasonable design of the corrugated compensator, it has a long service life, which reduces the frequency of replacement and maintenance.

Product parameters

Corrugated compensator classification

Corrugated compensators can be divided into many types according to their different structural forms and uses. Among them, the common ones include axial corrugated compensators, transverse corrugated compensators, angular corrugated compensators and composite corrugated compensators. Different types of corrugated compensators have different characteristics and application scenarios, and need to be selected according to the specific use environment.

Product installation and maintenance

1. Pre-installation inspection: Ensure that the actual length of the expansion joint is consistent with the specified maximum installation length, if it is inconsistent, it needs to be adjusted with an adjusting screw.
2. Installation length: The installation length of the one-time compensation expansion joint should be equal to the shortest working length plus the maximum compensation amount.
3. Preheating and welding: After the pipe network is preheated, the jacket of the expansion joint is welded twice at the lap joint, so that it is fixed and no longer has a compensating effect.
4. Pressure test: After installation, the pressure test needs to be carried out, and the test pressure is 1.5 times of the design pressure.
5. Thermal insulation treatment: The expansion joint should be insulated as a whole, and the thickness of the insulation layer should be consistent with or similar to the thickness of the pipeline insulation layer.
