• A threaded  flange is a type of flange made from steel with a threaded hole in the middle. Connects to small pipes by rotating the thread.
• Hollow flanges are flanges made from steel with a round hole in the middle; they are responsible for connecting pipes with water industry materials.
• A blind steel flange (BLIND STEEL FLANGE) is a type of flange made from steel material without a hole in the middle. This type of flange is used to temporarily block the ends of pipes.

Classification by connection surface

• RF (RAISED FACE STEEL FLANGE) is a type of flange with a raised flange. FF (FLAT FACE STEEL
• FLANGE) is a type of flange without a raised flange or can be said to be a type of flange with a flat surface.
