Threaded Flange ASTM A105 ASME B16.5 is American standard carbon steel flange.Threaded flange is widely required as pipe flange, that is, threaded pipe flange is used in different industrial applications.
Threaded flange, also known as threaded flange, has a thread in the flange hole, which matches the external thread on the pipe. This type of joint is fast and simple, but it is not suitable for high pressure and high temperature applications. Threaded flanges are mainly used for public facilities such as air and water.
Threaded (screw) flanges are similar to slide in flanges, but the holes are threaded. Its main advantage is that it can be assembled by welding, which shows that it can be used in low-pressure equipment at room temperature and in high explosion areas where welding will cause danger.
They are a special type of pipe flanges that can be connected to the pipe without welding.
Size: 1/2 inch to 4 inch for standard ASME B16.5,
Pressure: Class 150, Class 300, Class 600, Class 900, Class 1500 and Class 2500.
Sealing face: RF (raised face), RTJ (ring joint face), TG (tongue and groove face) etc
Types of Screwed Flanges
There are various types of threaded flanges are as follows:
1. Plain Threaded Flanges
2. Female Threaded Flanges
3. Male Threaded Flanges
Standards, Dimensions & Weight
Threaded flanges can be used in high pressure environments and their main advantage is that they can be assembled without welding.

Advantages of threaded flanges :
Threaded flanges are threaded in holes that match the external thread of the pipe. Threaded flanges are used with pipes with external threads. These flanges have the advantage of joining without welding.
Threaded flanges are often used for small diameter, high pressure requirements. thread flanges with a hub have published specifications that range from 1/2″ thru 24″.
