Products Description
PVC Extended Expansion Joint is an expansion joint used to connect pipes. It mainly absorbs the displacement caused by thermal expansion and contraction of pipes and is commonly used in water supply and drainage and industrial piping systems.
why choose us?
High-Precision Extrusion Production Line
The company has imported German Battenfeld extrusion equipment to precisely control the flow rate and temperature of the PVC material, ensuring uniform wall thickness of the expansion joint and enhancing its elasticity and durability.
ASTM D3139 Standard
Manufacturing strictly complies with ASTM D3139 standards. Products are CE and ISO 9001 certified, ensuring that the Extended Expansion Joint meets European and American market technical specifications.
Customized Protective Packaging
To address the easily deformable nature of PVC soft pipe fittings, the company has designed multi-layer reinforced packaging and uses automated packaging lines. Combined with professional logistics, this ensures product integrity.
Application Scenario
Pipeline Movement Compensation in Water Supply and Drainage Systems
In water supply and drainage systems, PVC Extended Expansion Joints are used to absorb thermal expansion and contraction caused by temperature fluctuations, compensating for pipe movement and preventing pipe ruptures due to stress concentration.
Vibration Isolation in Industrial Piping Systems
In industrial piping systems, PVC Extended Expansion Joints are used to connect pipes, absorbing vibration and movement during operation, reducing stress in the piping system and extending its service life.
Pipe Expansion Compensation in Building Structures
In building structures, PVC Extended Expansion Joints are used to connect pipes, compensating for pipe movement caused by building settlement or temperature fluctuations, and ensuring the normal operation of the piping system.
FAQ
Q: What piping systems are suitable for the PVC Extended Expansion Joint?
A: It is primarily used in water supply and drainage, industrial, and building piping systems to compensate for expansion and contraction caused by temperature fluctuations.
Q: How much expansion and contraction can this product withstand?
A: It is designed to accommodate a wide range of axial expansion and contraction and slight lateral movement in the pipe.
Q: Are there any requirements for pipe orientation during installation?
A: During installation, ensure that the pipe axis is aligned to avoid excessive lateral deviation that could affect performance.
Q: Is this joint suitable for high-temperature pipes?
A: It is suitable for ambient and low-temperature environments, but not for high-temperature or high-pressure piping systems.
Q: How can a leak-tight connection be ensured?
A: Proper sealing rings and proper installation techniques are required to ensure a tight, leak-free joint.
