Threaded union joint is a common pipeline connection device commonly used in the oil and gas industry and other industrial fields.
Features
1.Thread connection:
Union joints usually use thread connection, which is relatively simple and easy to install and disassemble.
2.High pressure resistance:
Due to its widespread use in high-pressure environments, threaded UNION joints are usually designed to withstand higher pressure structures.
3.Reliability:
The design of UNION joints considers stability and reliability, ensuring stable connections under various working conditions.
Advantage
1.Easy installation and disassembly without the need for professional tools.
2.High pressure resistance, suitable for high-pressure pipeline systems.
3.High reliability, able to maintain stable connections in harsh working environments.
Disadvantage
1.Compared to welded connections, threaded connections may pose a risk of leakage.
2.Attention should be paid to correct thread alignment during installation, otherwise it may result in loose connections.
3.Application scope: The threaded union joint is widely used in pipeline systems in fields such as petroleum, natural gas, chemical, and water treatment. Common uses include wellhead devices, pipeline connections, and high-pressure pipeline systems.
Overall, threaded union joints are a common and practical pipeline connection device, particularly suitable for situations that require frequent disassembly and maintenance, while also meeting the needs of high-pressure working environments.
Effect
1. One of the main features of this product is that its structure is made of EPDM and NBR materials.EPDM (ethylene propylene diene monomer) and NBR (nitrile butadiene rubber) are known for their excellent weather resistance, ozone resistance and heat resistance, making them ideal for outdoor and high-temperature applications.This ensures that the threaded rubber expansion joint can withstand harsh environmental conditions, providing long-term performance and durability.
2. The connection method of threaded rubber expansion joint is internal thread, which is easy to install and maintain.Its production method uses casting, which ensures a precise and uniform surface finish, helping to improve its overall quality and reliability.
3. In industrial environments where vibration, motion and thermal expansion are common, threaded rubber expansion joints play a vital role in maintaining the integrity of piping systems.Its ability to absorb the effects of these elements helps prevent pipe and equipment damage, ultimately reducing maintenance costs and downtime.
Application
1. Threaded rubber expansion unions are manufactured to ANSI, JIS and DIN standards and are designed to provide flexibility and vibration absorption to piping systems. Made from EPDM and NBR materials, these union joints offer excellent resistance to corrosion, heat and pressure, making them suitable for a variety of applications. Specifications range from DN6 to DN250, and the connection method is female joint, which can adapt to different pipe sizes and configurations.
2. One of the main advantages of threaded rubber expansion joints is their ease of installation and maintenance. Threaded connections allow for quick, secure installation, reducing downtime during installation or replacement. Additionally, the cast production method ensures the durability and reliability of the joint, providing long-term performance in demanding environments.
3.In industrial settings, these unions are commonly used in piping systems such as water supply, HVAC, chemical processing, and more. Their ability to absorb motion and reduce noise makes them ideal for applications where vibration and thermal expansion are concerns. Additionally, the flexibility of unions can accommodate misalignment and offset, helping to increase the overall efficiency and longevity of the piping system.
