Are steel braided hoses better?

Hoses are an integral part of your home&#;s plumbing appliances, but not all hoses are not created equal.

If your appliances, such as your washing machine and your dishwasher, have rubber hoses, it&#;s time to consider upgrading them to braided steel hoses.

Here are some of the top reasons to replace the rubber hoses on these appliances.

Braided steel hoses last longer

You&#;ll get a lot more use out of a braided steel hose on your washing machine or dishwasher than you will a rubber hose, which are sensitive to heat, water, and chemicals. Those elements can lead to leaks or bursts, possibly leading to flooding and water damage. Steel hoses, though, are tougher and can withstand more wear and tear, such as higher water pressure.

Braided steel hoses are safer

Because a steel hose is less likely to burst and cause water damage to your home, you&#;re also less likely to heave to deal with electrical hazards and slippery surfaces that could cause you or your family members to trip and fall.

Braided steel hoses don&#;t bend

Rubber hoses are easily bendable, which hampers water flow and therefore how well your washing machine and dishwasher works. Steel hoses are rigid and won&#;t kink or bend like a rubber hose will.

How to replace a rubber hose on your washing machine

If you want to replace your washing machine&#;s rubber hose, you&#;ll just need a few items aside from two steel hoses &#; a bucket, a pair of pliers, and some towels. Here&#;s how to do it:

1. Locate your breaker box and turn off the power to your washing machine and dryer, then unplug the washing machine.
2. Pull the washing machine out from the wall.
3. Turn off the water supply. You&#;ll be able to see the two rubber hoses that are for hot and cold water.
4. Remove the rubber hoses, but first put the bucket beneath the hookup for water. You might need to use the pliers to turn the hose fittings clockwise.
5. Before you attach the hoses, be sure that the washing machine is inside the hose connector. Make sure the connections are tight and secure, but don&#;t overtighten.
6. Turn on the water supply and check for leaks.
7. Plug in the washing machine and turn on the power at the breaker box.

How to replace a rubber hose on your dishwasher

1. Locate your breaker box and turn off the power to your dishwasher.
2. Shut off the water supply valve for the dishwasher, which will probably be either under the sink or in your basement. If you can&#;t find it, give us a call!
3. Take a 1/ 4 inch nut driver and remove the dishwasher&#;s bottom front access panel and toe panel.
4. Pull out the dishwasher. First, you&#;ll have to find your junction box behind the appliance&#;s bottom front access panel. Disconnect the wires and remove the two screws that from the brackets connect the dishwasher to the cabinet opening.
5. Disconnect the drain hose from the drain pump &#; you may have to use pliers.
6. Remove the drain hose from the water inlet assembly. You&#;ll need channel lock pliers to disconnect the assembly, which connects the drain hose to the dishwasher&#;s outside left panel. Pull out the assembly to release the drain hose.
7. Disconnect the drain hose from the drain line to the kitchen sink.
8. Connect the new steel hose to the drain pump, then secure it with the wire hose clamp. Pull it through the water inlet bracket, then connect to your sink.
9. Reinstall the water inlet bracket and the dishwasher.
10. Restore the water supply by opening the water supply valve, then turn the power back on at the breaker box.

While braided steel hoses do last longer, you&#;ll still need to plan on replacing them over three to five years. Even though steel hoses are far less likely to kink or leak, you should still inspect them once or twice annually just to make sure there is no damage.

STAINLESS STEEL BRAIDED HOSE

What is stainless steel braided hose?

A hose consisting of a corrugated stainless-steel core with stainless steel braid, each working together with their own function. While the corrugated stainless hose carries the pressure and has great hoop strength. It needs the tensile strength of the braid to keep it from elongating.

Stainless steel braided hose pressure rating

Every hose has its own pressure rating. There are several variables that effect a hose pressure rating.

&#;Diameter
&#;Hose thickness
&#;Braid design
&#;Corrugation shape
&#;End fittings used.
&#;Temperature

Always make sure the hose you select has a pressure rating that will handle the application.

Stainless steel braided hose bend radius

The bend radius of a hose is the minimum radius a hose can be bent in without compromising its integrity. The bend radius is used to determine the length of hose (life length) needed for a specified movement. There are generally two types of bend radii indicated for a hose and braid product. A &#;Static&#; bend radius used to determine hose length for an offset in the piping that will not see movement. The other bend radius is the &#;Dynamic&#; bend radius, and this is used to determine the length of hose needed for application that will see cycling movement such as in a HVAC system.

Always used the bend radius of the specific hose you will be using. Each hose has its own bend radius.

If you are looking for more details, kindly visit flexible hydraulic hose.

ISO should be used to determine the bend radius.

What is live length when referencing stainless steel braided hose product?

The live length is the length of hose between the braid collars.

Why Use Corrugated Stainless Steel Braided Hoses?

Corrugated stainless steel braided hoses incorporates time tested and proven technology that have several advantages over rubber hoses including:

&#;Higher temperature rating than rubber flex connectors
&#;Higher pressure limits than rubber flex connectors
&#;OK for outdoor applications
&#;Longer life than rubber
&#;Easily customized

Metal hoses are also available with a wide range of end fittings:

&#;Flanged, including plate, raised face, and weld neck
&#;Thread
&#;Grooved
&#;Weld end
&#;Sweat
&#;Specialty fittings as specified.

What does it mean when a hose is &#;braided&#;?

Braid used with corrugated stainless steel hose has two functions.  The first is to restrain the hydrostatic end load of the hose under pressure.  The second is to restrain the hose from squirming under pressure and stay flexible.  The braid basically acts like a &#;Chinese finger trap&#; around the hose.

Braid is available in two styles.  Single braid as shown in Picture 20a. and braided braid as shown in.  Single braid is made up of groups of wires called carriers or bands.  Braided braid is made up of wires braided together to form the carriers or bands.

Braid is described in the following format, 72 x 8 x .020 where 72 is the number of carriers or bands in the braid, 8 is the number of wires per carrier, and .020 is wire diameter,

Braided braid is described with the same format but with brackets.  For example, 96 X (13 X .025)

The pressure rating of a hose and braid assembly are dependent on several factors that include:

&#;Hose design (shape of corrugations)
&#;Hose thickness
&#;Number of braid wires
&#;Diameter of braid wires
&#;Braid angle (the angle that the braid wires run around the hose)
&#;Braid coverage (how much of the hose is covered by braid)
&#;Material of hose and braid

What are braided hoses used for?

The list of applications for hoses is just about endless.  The reasons for needing hose and braid products can range from making up for offsets in the piping to compensating for thermal / seismic / building movement.  Some of the most common includes:

&#;Heating and cooling water systems.
&#;Domestic water.
&#;Steam and condensate systems.
&#;Natural gas lines.
&#;Fire sprinkler piping.
&#;Refrigeration lines.
&#;Exhaust lines
&#;Vent lines
&#;Compressed air.
&#;Medical gas.

Always consult Metraflex to review your application. We offer Delegated Design services and are happy to help.

How Long do Stainless Steel Braided Hoses Last?

A properly installed and applied hose and braid product should be considered a life of building product that will last 20 years.

However, there are several factors that can adversely affect the life of hose and braid products:

&#;Corrosion.  There are several material options available for the hose, make sure that the proper hose material is selected for the application.
&#;Erosion.  For high velocity applications a liner can be used to protect the hose.
&#;Excessive movement.  This can be easily avoided by ensuring the proper product was selected and installed.
&#;Excessive vibration.  For some high movement applications longer hoses are used.  For some high frequency applications, a rubber connector may be preferred.
&#;Physical damage
