How to Fabricate Metal Hose Assemblies

23 Jul 2020 Industrial Dampers

In many facilities that deal with the transference of fluids and gases at extreme temperatures, flexible metal hose assemblies are the transferal method of choice. Metal hoses are extremely durable and long-lasting and, at Flextech Industries, we manufacture flexible options that can withstand temperatures ranging from -382 degrees Fahrenheit to 1,500 degrees Fahrenheit. If you have a facility that struggles with thermal pressure or misalignment, it is worth knowing how to fabricate metal hose assemblies.

How Metal Hose Assemblies are Fabricated

Manufacturing metal hose assemblies is something that requires the proper industrial setup. Without the right tools, it is very difficult to create hose assemblies that can withstand the kind of pressure that is required. The steps needed to fabricate a metal hose assembly for industrial use are:

1.     Cut the Metal Hose to the Required Length

Using a rough cutting tool, the flexible metal hose is cut from the spool at a bit more than the desired length. This hose typically includes both the braided exterior and the corrugated interior. The braided exterior is then removed from the flexible interior hose to separate the two elements and make them easier to work on. The core hose is then cut to the exact measurement required when paired with the end fittings.

2.     Apply the Fitted Collars to the Hose Assembly

The interior corrugated hose is then reunited with the braided exterior. The interior hose will be a bit shorter than the exterior hose. Collars are then placed on the outside of the existing assembly. Once they are properly in place, they are crimped together to ensure that the collars do not shift.

3.     Trim the Braid

After the collars are holding the braid and the interior hose together, the exterior braid is trimmed back to meet the edges of the collars and the interior hose.

4.     Weld the End Fittings to the Assembly

At this point, the end fittings can be welded onto the assembly in a way that leaves no gaps for gas or fluids to escape through the weld. After welding the fittings on, the ends are polished to ensure that everything looks seamless.

5.     Test the Hose Assembly

After the hose is completely outfitted with fittings, the entire assembly is tested for leaks and quality.
