Hot-Selling Flange 1.4301 - ASME B16.5 CarbonStainless Steel Threaded Flange – Xinqi

Product Description

Threaded flange refers to a kind of flange that uses threads to connect with pipes. Threaded flange is a kind of non-welding flange, which processes the inner hole of the flange into pipe threads, and is matched with the threaded pipe to realize the connection. Compared with the flat welding flange or the butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed. Alloy steel flanges have sufficient strength, but are not easy to weld, or the welding performance is not good, and threaded flanges can also be selected. However, when the temperature of the pipeline changes rapidly or the temperature is higher than 260°C and lower than -45°C, it is recommended not to use threaded flanges to avoid leakage.

Flange Types

Weld Neck

This flange is circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications
erosion inside the pipeline. The weld neck is therefore favoured in critical applications.

Slip-on
This flange is slipped over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications.

Blind
This flange is used to blank off pipelines, valves and pumps, it can also be used as an inspection cover. It is sometimes referred to as a blanking flange.

Socket Weld
This flange is counter bored to accept the pipe before being fillet welded. The bore of the pipe and flange are both the same therefore giving good flow characteristics.

Threaded
This flange is referred to as either threaded or screwed. It is used to connect other threaded components in low pressure, non-critical applications. No welding is required.

Lap Joint
These flanges are always used with either a stub end or taft which is butt welded to the pipe with the flange loose behind it. This means the stub end or taft always makes the face. The lap joint is favoured in low pressure applications because it is easily assembled and aligned. To reduce cost these flanges can be supplied without a hub and/or in treated, coated carbon steel.

Ring Type Joint
This is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flanges.
