ASME Standard High Strength Metric Stainless Steel U Bolts For Pipe
Description:
A U-bolt is a bolt in the shape of the U with thread on both ends. It also has square shape.
U-bolts have mainly been used to support pipe use, pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by the size of pipe it was supporting.
For example, a 40 Nominal Bore U-bolt would be asked for by pipe work engineers, and only they would know what that meant. In reality, the 40 nominal bore part bears little resemblance to the size and dimensions of the U-bolt.
The nominal bore of a pipe is actually a measurement of the inside diameter of the pipe. Engineers are interested in this because they design a pipe by the amount of fluid / gas it can transport.
The material can be stainless steel and carbon steel, or we can produce as customer requirements.
