Loose flanges are widely used in stub ends. In these cases, welding is not required. Loose flanges are bolted to another flange, leaving them "loose," meaning they are not welded. They end up loose in the line.
The use of a loose flange is recommended in some cases:
- The loose flange is ideal for integrating operations where the pressure level is low;
- Loose flange is ideal when system cost must be low;
- The loose flange is ideal for integrating stainless steel lines;
- The loose flange is ideal for working on sets with eyelashes.
More information on loose flange application
The application of the loose flange can be considered identical to that of the smooth flange, with the main difference between these two types of part being a characteristic of the loose flange: it has a protrusion on one side of the face of the part.
Loose flanges are made according to the following standards:
- ASTM
- ANSI
- MSS
- DIN
The main advantages of the loose flange are:

- Easy fixing.
Where is the loose flange used?
Loose flanges are used in industrial piping worldwide. These parts are perfect for assembling and disassembling pipes and are used in a variety of projects, both complex and simple.
This type of flange is recommended for use in pipelines that require periodic maintenance, as quick disassembly and assembly make this type of work easier.
Loose flanges are required to be part of systems that may undergo future modifications. A common industrial term for loose flanges is " lap-joint ."
To reinforce this point, it's very common to find the flange loosely attached to eyelashes. Because it's easy to attach, installation doesn't require welding; just screws.
Loose flange systems are considered ideal for those where low-pressure fluids are present. One of the biggest attractions of this type of flange is its low cost, followed by ease of operation.
