Flanges are an essential component used in pipework. They act as a connecting tool between two or more pipes, ensuring a secure and tight sealing of the joints. Different flanges exist, each with unique features, designs, and applications.
Weldo Flange is a flange used to connect two pipelines of different diameters. Wielding is used to connect both pipelines and the Weldo Flange altogether. There exist two types of Weldo Flange. The first type is termed a Long Welded Neck. This type has a neck with the same diameter as the pipe and an extended flat area, which acts as a method for its attachment. The second type is the Short Weld Neck Weldo Flange. Unlike the Long Welded Neck, the Short Weld Neck has a small area for retaining the pipeline connection and its attachment to the neck.

Nipo flanges are a type of flange used as an inlet- and outlet connection of equipment. They are of two types- the Nipo Flange and elbow Nipo Flange. Nipo Flanges are generally used for high-pressure applications such as chemical processing and oil refineries. The elbow Nipo Flanges have a ninety-degree angle, making them ideal for applications that need to change pipeline flow direction.

Weldo Flanges find extensive use across several sectors, including construction, oil and gas, chemical plants, and automotive construction. They are used in these industries to connect different types of pipes in the pipeline system. Nipo Flanges find application in the upstream and downstream oil, gas, and chemical process industries.
Weldo Flanges offer significant benefits such as improved reliability, excellent corrosion resistance, and mechanical strength. Therefore, they are ideal for use in high-pressure pipeline systems. Nipo Flanges, on the other hand, are easily incorporated into a pipeline system, saving both time and human resources. These compact flanges can withstand high pressure and temperature, making them a cost-effective solution for joining pipes.
Weldo Flange and Nipo Flange are essential components used in pipelines. They ensure a tight and secure connection between pipes, making them useful in several industries.
