Flanges NPT Class 150
Threaded
This flange is referred to as both threaded or screwed. It is used to join different threaded elements in low pressure, non-critical applications. No welding is required.

Flange types:
Weld Neck This flange is circumferntially welded into the gadget at its neck which ability that the integrity of the butt welded vicinity can be without difficulty examined by using radiography. The bores of each pipe and flange match, which reduces turbulence and erosion inner the pipeline. The weld neck is consequently favoured in indispensable 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 clean off pipelines, valves and pumps, it can additionally be used as an inspection cover. It is now and again 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 both threaded or screwed. It is used to join different threaded elements in low pressure, non-critical applications. No welding is required. | |
Lap joint This flange is used with either a stub end or taft which is butt weled 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 this flanges can be supplied without a hub and/or in treated, coated carbon steel. | |
Ring Type Joint This is a approach of making sure leak proof flange connection and excessive pressures. A steel ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing technique can be employed on Weld Nexk, slip-on and blind flanges. |
