Product Introduction

Loose-set flange, also known as loose-set flange or semi-fixed flange, is a common pipe connection. Its main feature is that the inner and outer rings of the flange are welded structures, and the middle part of the loose sleeve can be freely expanded to adapt to the displacement of the pipeline due to temperature changes or thermal expansion and contraction.

The working principle of the butt welded ring loose sleeve flange is: when the pipeline is heated and expanded, the inner ring and outer ring of the flange will not produce relative displacement, but the middle loose sleeve part absorbs the expansion amount to maintain the tightness and integrity of the pipeline system. This not only avoids the damage caused by expansion of the pipeline, but also reduces the wear of the flange and prolongs the service life.

This kind of flange is widely used in high temperature, high pressure, large diameter and frequent disassembly occasions, such as power plants, chemical plants, oil and gas transmission pipelines. Because of its flexible structure and easy installation, it is widely used by the industry.

Product Usage

Welding Ring Flange (Welding Ring Flange) is mainly used in high pressure, large diameter pipe connections, especially in high temperature, high pressure, high corrosion or need frequent disassembly. Its main features are:

1. High strength: butt welded ring is usually made of high-quality carbon steel or alloy steel, with high strength and pressure resistance, can withstand high working pressure.

2. Good sealing: the connection between the flange and the pipeline is achieved by welding, and the sealing performance is good, reducing the possibility of leakage.

3. Easy maintenance: Due to its structural design, if it needs to be replaced or repaired, only the flange part needs to be replaced, rather than the entire pipe.

4. Easy disassembly: the loose sleeve flange of the welded ring can provide a quick disassembly method, which is very suitable for equipment or pipelines that need to be disassembled frequently.

5. Flexibility: The flange can be installed and adjusted independently of the pipe, providing greater installation space and flexibility.

Therefore, butt welded ring loose sleeve flange is widely used in petrochemical, electric power, metallurgy, aerospace, ocean engineering and other fields of high pressure pipeline system.
