Product Introduction

Double flange limit expansion joint is an important element used for pipeline connection, which is mainly composed of body, sealing ring, gland, limit screw, limit expansion tube, nut and bolt and other components. Its main function is to expand and contract freely within the allowable expansion and contraction of the pipeline, once the maximum expansion and contraction amount is exceeded, the limiting device will play a role to ensure the safe operation of the pipeline, especially suitable for the pipeline with vibration or a certain slope and bend.

Product structure composition

The main components of the double flange limit expansion joint include:
1. Body: Withstand the pressure and thrust of the pipeline.
2. Sealing ring: To prevent leakage, usually made of NBR nitrile rubber, the sealing area is large, the greater the force, the tighter the sealing.
3. Gland: Fix the sealing ring to prevent leakage.
4. Limiting screw: Limit the maximum expansion and contraction of the pipeline to prevent damage caused by excessive displacement .
5. Limit expansion and contraction pipe: Allow the pipeline to expand and contract freely within a certain range.
6. Nuts and bolts: Fix and adjust the position of the pipe.

Product features

1. Compact structure and reasonable design: The double flange limit expansion joint is composed of main components such as the body, sealing ring, gland, extension and short tube, etc., which is compact and reasonably designed, and can withstand large pressure and temperature fluctuations.
2. Large expansion and contraction: The joint can absorb large pipeline displacement and ensure that the pipeline can expand and contract freely in the allowable expansion and contraction, especially suitable for the connection in the pipeline with vibration or a certain inclination and bending.
3. Good sealing performance: The sealing ring is made of high-temperature resistant and corrosion-resistant materials, such as high-quality rubber or PTFE, etc., which can ensure the tightness of the pipeline system and prevent the leakage of the medium.
4. High pressure: The joint can withstand high pipeline pressure to ensure the safe and stable operation of the pipeline system in a high-pressure environment.
5. Limit protection: Add a limit device, lock with a double nut at the maximum expansion and contraction, and effectively prevent damage or leakage caused by excessive expansion and contraction of the pipeline.

Product Advantages

1. Easy to adjust: It can be freely expanded and contracted within a certain range to adapt to the physical expansion and contraction of the pipeline caused by temperature changes, foundation subsidence and other factors.
2. Easy installation: Flange connection is adopted, which is easy and quick to install, which can effectively improve engineering efficiency and construction quality.
3. High safety: Through limit protection and good sealing performance, the stability and safety of the pipeline system are ensured, and the risk of leakage and explosion is reduced.
4. Strong adaptability: Suitable for a variety of media, including seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas and steam with a temperature of no higher than 250 degrees.
5. Shock absorption and noise reduction: Through its elastic deformation ability, it can absorb and alleviate the vibration and noise in the pipeline system, improve the working environment, and improve the operation efficiency of the system.
6. Significant economic benefits: Reduce equipment damage and maintenance costs caused by pipeline vibration, leakage and other problems, and reduce the overall operating costs.

Product Applications

1. Thermal piping system: Due to the large temperature change, the pipeline will produce thermal expansion and cold contraction. The B2F double-flange limit expansion joint can effectively absorb this change in pipe length caused by temperature changes, preventing damage to pipes or connectors due to excessive stress.
2. Industrial piping system: Suitable for petroleum, chemical, metallurgical and other industrial fields. The pipes in these systems are often subjected to harsh conditions such as high temperatures, high pressures, and corrosive media, and the corrosion resistance and high temperature resistance of B2F joints can meet these requirements. Its limit function can limit the excessive displacement of the pipeline and ensure the stable operation of the pipeline system.
3. Water supply and drainage pipeline system: In the urban water supply and drainage pipeline system, the pipeline may produce displacement or vibration due to factors such as water flow velocity, pressure changes, and soil settlement. B2F double-flange limit expansion joints can absorb these displacements and vibrations to protect the safety of piping systems, especially in long-distance water pipelines and large drainage networks.
