Flanges are responsible for connecting two devices together, such as pipes and pipes, pipes and valves, pipes and various measuring devices.
There are 5 types of flanges that are commonly used today.
- Weld Neck Flange
- Slip on Flange
- Threaded Flange
- Socket Weld Flange
- Blind Flange
Weld Neck Flange

It is designed for use in high pressure or high temperature applications. And don't worry about cracks.
that will happen to the weld line Due to pressure or stress (STRESS) that occurs on the flange.
It is passed through the neck area of the flange before reaching the weld line.

Slip on Flange

Slip-on flanges are very popular. By inserting the pipe into the bore of the flange. Then weld both the outside and inside. This type of flange is cheaper than the high neck flange. It has the characteristics
Similar to a welded flange. The difference is that the slip-on flange does not have a shoulder. (in the area of the bord)
The welded flange has a shoulder. (in the area of the bord)

Threaded Flange

It is a flange with a threaded bore. Commonly used with flange sizes from 2" and below. Suitable for
Work with low pressure and temperature Can be assembled, installed or dismantled for easy maintenance.
Because it uses a screw connection method. No welding required This makes it safe to install in areas with fuel. Because you don't have to worry about sparks caused by welding.

Socket Weld Flange

It is a welded flange. Commonly used with flange sizes from 2 and below. Suitable for work with high pressure and temperature.
Blind Flange

Blind flanges are designed to block or stop fluid in a pipe.
