Ductile iron expansion device

The ductile iron pipe has good adaptability to axial displacement compensation of ductile iron pipe. It is suitable for ductile iron pipe with large axial displacement Good compensation effect, compared with steel pipe expansion and rubber joint, it has high temperature resistance and wear resistance, which is often used in chemical pipeline and powder transportation pipeline. The ductile iron expansion joint in our factory is generally made of high-quality nodular cast iron after high-temperature melting and EPC treatment, which has good sealing effect and processing accuracy, so as to ensure that there will be no leakage during installation and use.

Ductile iron expansion joint is the main product of our factory. The flange type expansion device using ductile iron qt410 generally has good absorption function of axial and radial displacement, and has good adaptability for pipe bending. The main reason is that ductile iron material is relatively soft, which is suitable for large angle compensation pipeline, and has good effect for axial displacement caused by pipeline settlement Good compensation effect, compared with steel pipe expansion and rubber joint, it has high temperature resistance and wear resistance, which is often used in chemical pipeline and powder transportation pipeline. The ductile iron expansion joint in our factory is generally made of high-quality nodular cast iron after high-temperature melting and EPC treatment, which has good sealing effect and processing accuracy, so as to ensure that there will be no leakage during installation and use.

Scope of application:
Ductile iron expansion joint of our company is mainly used in power plant, water plant, sewage treatment plant, various chemical pipeline and oil pipeline.
Flange connection standard: gb9115 standard.
Working pressure: 0.6MPa, 1.0MPa, 1.6Mpa, 2.5MPa, 4.0Mpa.

Precautions for installation and use of ductile iron expansion joint:
1. The model, specification and pipeline configuration of ductile iron expansion joint should be checked before installation, which must meet the design requirements.
2. Pay attention to the direction of rotation of the inner hinge sleeve of the cylinder with the same direction as that of the inner plane of the telescopic sleeve.
3. For the expansion joint that needs to be "cold tightened", the auxiliary components for pre deformation should be removed after the pipeline installation.
4. It is strictly forbidden to use the method of expansion joint deformation to adjust the installation out of tolerance of the pipeline, so as to avoid affecting the normal function of the expansion device, reducing the service life and increasing the load of the piping system, equipment and supporting components.
5. During installation, welding slag is not allowed to splash on the surface of the wave shell and other mechanical damage is not allowed.
6. After the piping system is installed, the Yellow auxiliary positioning components and fasteners used for installation and transportation on the wave expansion device should be removed as soon as possible, and the limiting device should be adjusted to the specified position according to the design requirements, so that the pipeline system has sufficient compensation capacity under environmental conditions.
7. All moving elements of the expansion device shall not be stuck or restricted by external components, and the normal operation of each moving part shall be ensured.
8. During the water pressure test, the secondary fixed pipe support at the end of the pipeline with expansion device shall be reinforced to prevent the pipeline from moving or rotating. For the expansion device and its connecting pipeline used in gas medium, it is necessary to add temporary support when filling water. The content of 96 chloride ion in the cleaning solution for water pressure test shall not exceed 25ppm.
