4-tube 1 '' -8unc u bolts can be used to support flexible conduit, intermediate metal conduit, or galvanized pipe. This article will help you understand how to install it. You will learn about its applications, such as supporting flexible conduit, intermediate metal conduit, and Galvan. In addition, learn how to choose the correct size for the type of pipe you are installing.
Application: support Galvan
U-bolt is a "U" shaped fastener with machine threads at both ends. Screw the nut onto the U-bolt to fix the pipe to the supporting structure. In addition to pipe supports, U-bolts are also used to secure other materials, such as conduits, pipes, or other types of pipes. They can also be anchored in concrete as anchor bolts. These bolts are usually made of carbon steel and have a hot-dip galvanized surface to provide corrosion resistance.
Intermediate metal conduit (IMC)
Whether you are installing IMC or galvanized rigid conduit, U-bolt is an important part of installation. large
The diameter and smooth interior of IMC make it much easier for wires to pass through it than RMC. This type of catheter is allowed in most applications using RMC and is being replaced in many other applications.
IMC is the intersection between rigid metal conduit and EMT. It is lighter and thinner than rigid metal conduit, but strong enough to protect insulated cables. These two types use the same manufacturing process of resistance welded pipe. Both IMC and EMT can be used with the same coupling. Both the inner and outer walls of these two types of conduits are coated with zinc to provide additional corrosion protection.
IMC product line aims to provide the same strength and durability as rigid steel pipe, but it is lighter and cheaper. This product line provides standard and patented IMC Kwik coupling (R) alternatives. In addition to IMC, allied tube& The conduit (R) is also provided with a series of rigid couplings, elbows and threaded joints for easy installation.
Support flexible conduit
In a preferred embodiment of the present invention, a chain support for a flexible conduit is used. The support chain includes
Multiple interconnection links rotating between two limit positions. In the preferred embodiment, the limit design is that one end of the chain is horizontal and the other end is bent. Two pins are fixed on one plate, and complementary arc grooves are formed on the other plate. The pin positions are spaced from each other and relative to the pivot point.
There are two wall thicknesses of flexible metal conduit: thinning and full wall. The former provides more protection against mechanical forces. The wall reducing flexible metal conduit can adopt high-grade galvanized steel and aluminum alloy strip with unified specifications. Both types are used in flexible metal conduit systems and are listed by UL according to NEC. The former is recommended to be used where additional flexibility is required, and the latter is easier to use.
During installation, the flexible metal conduit must be supported with pipe clamps. In addition, it may be necessary
Strengthen the connection with screws. These are easy to install and disassemble. They can also be installed on slopes. Flexible metal conduit can also be used as grounding path. Some local regulations require the use of green grounding wires. Flexible metal conduit can support up to 4 inches of cable.
