Stainless Steel 8D Bends are made up of different material grades and in different standards. These pipe bends have the bending radius equal to 8 times the outer diameter of the pipes they are fitted on to. There are different types of bends and the 8d bend dimensions vary according to the different standards. The material grades vary based on the application type as well. There are austenitic, martensitic, super duplex and alloy steel materials that are used to make these bends. The ASME B16.9 Buttweld 8D Bend belongs to the ASME B16.9 standard which covers pipe fittings ranging in size from ½ inches through 48 inches.
8D Seamless Pipe Bend
ASTM A234 WPB 8D Pipe Bends
The schedules of the fittings range from 5S to 160S and XXS with custom schedules available. There are different specifications to address the requirements for the different application types. The ASTM A234 WPB 8D Pipe Bends are made up of wrought carbon steel and allow steels. The WPB stands for wrought, pressure fittings of grade B. There are different types of fittings such as seamless, ERW, welded and fabricated fittings.
The Alloy Steel 8D Bends are used in high end applications where the corrosion resistance is required at high levels. Alloy steel fittings are also usually more expensive than the austenitic stainless steel fittings. We can provide you with more information on the 8D Pipeline Bend and the different types and grades along with prices.
