The Differences Between Forged Flanges and Cast Flanges
ARE FLANGES FORGED OR CAST?
Flanges can either be forged or cast. Both manufacturing methods have their advantages and disadvantages, depending on the application you have in mind for your flange. Here at Texas Flange, we primarily deal with forged flanges due to the outdated nature and lower standard of quality of cast flanges. Below, we will delve into the advantages and disadvantages of both forged steel flanges and cast iron flanges.
Different Types of Flanges and Their Uses
Used to connect valves, pipes and other equipment, flanges are forged rings that come in many different shapes and sizes and are used in a wide range of industries around the world. With so many varieties and specifications, it might be difficult at first to recognise which is the right one for you. Here's a rundown of some of the most common and popular types of the flange and their uses:
The railway wheel
A typical railway wheel carries a load of about ten tonnes, roughly twice the equivalent for a road-going truck. The outer surface is called the tread. With a diameter typically of 1.0 m or less, the tread is roughly 100 mm wide. Like a pneumatic tyre, the railway wheel must handle the various forces needed to propel the vehicle forwards, slow it down, and hold it centrally on the track. But there are three striking differences.
Ideally, for a smooth ride the diameter of the wheel should be as large as possible (see Section G1209), and in fact, the driving wheels on some early steam locomotives were 9 feet (over 2.7 metres) in diameter. They were magnificent examples of craftsmanship, and they needed to be large because they were driven by connecting rods,
What Is an Axle Shaft?
An axle shaft is a solid steel shaft that runs from the differential and gear set of an axle housing to the wheel. Used in two distinct configurations, the axle shaft can be a straight shaft with splines machined into each end to engage both the differential on one end and a drive flange on the other. It also can be a straight shaft with splines machined into the differential end and a flange on the other to mount a wheel to the axle. The first design is primarily used with a full floating axle design, while the latter is commonly used on passenger cars and light pickup trucks.
A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially higher or lower than the ambient pressure. Examples include glassware, autoclaves, compressed gas cylinders, compressors (including refrigeration), vacuum chambers and custom designed laboratory vessels.
