Why do we use flexible hoses?

Flexi hoses are a type of plumbing pipe made from a variety of different materials. They have the advantage of being relatively flexible and easy to install and replace. This makes them popular among do-it-yourself (DIY) plumbing enthusiasts and professional plumbers.

For more information, please visit our website.

Flexi hoses come in several sizes, shapes, and colors to suit even the most complex pipe systems. The length of the hose can also be easily adjusted, making them ideal for hard-to-reach places. Flexi plumbing hoses are also known for their watertight connections, which help prevent any water leaks in your home.

While there are benefits to using flexi plumbing hoses, there are also drawbacks to using them. To help you choose the correct piping material for your house, we have created an extensive outline of the advantages, disadvantages, and applications of flexi hoses.

What Causes a Braided Water Hose to Break?

A braided water hose consists of a rubber inner tube surrounded by tightly-woven fabric and metal bands. These features offer greater resistance to abrasion and higher pressure ratings than traditional hoses. However, the design of flexi plumbing hoses is not indestructible.

As with standard water hoses, there are several common causes for breakage in a braided hose. Most involve external damage such as cuts or abrasions, over-flexing at tight angles, exposure to sunlight, freezing temperatures, or high temperatures that can cause cracking to the rubber tube.

Prolonged kinking or incorrect fittings can pull apart components of the effective braid layers. Long-term exposure to UV radiation is particularly destructive and should be avoided whenever possible. Finally, chemical immersion or contact with certain substances can eat away at coatings or otherwise weaken sections of the flexi hose, eventually leading to failure.

How to Prevent Flexible Water Hoses From Rupturing at Your Property

To prevent flexible water hoses from rupturing at your property, it is essential to routinely inspect them for signs of wear and tear. It&#;s important to take the time to look for any cracks or leaks that could lead to a rupture.

You should also regularly replace flexi plumbing hoses every five years to ensure they operate safely with minimal risk of malfunctioning or rupturing. Lastly, follow these steps below to help prevent flexi hoses from rupturing in your house.

1. Always Hire a Plumber to Install the Flexible Water Hose

Hiring a plumber to install your flexible water hose is an important decision that can save you money and prevent damage to your home. Plumbers have a wealth of knowledge on the correct types of hoses, connections, and fittings best suited for your situation.

They will also inspect the entire system to ensure everything is functioning correctly and up to code. If not installed properly, a flexible water hose can cause costly damage to walls, floors, and ceilings due to flooding and leaks.

Furthermore, since plumbing is a requirement for health codes, a do-it-yourself (DIY) job could leave you liable for fines or other penalties if the installation does not meet local standards. So, while hiring a plumber may cost more upfront, it&#;s the wisest decision in the long run.

2. Regularly Check Your Flexible Hoses For Rust Or Fraying

Checking your flexible hoses for signs of rust or fraying is a significant maintenance step. Run your fingers along the hose every three to six months to see any changes.

3. Install Mini Stop Taps On All Water Feed Connections

Another wise step for you to take is to add mini-stop taps on the fixtures and taps. This will help provide more protection in case of an emergency. Have your plumber install flexible hose connections with mini stop valves on all water lines. If the hose breaks or leaks, you can use the valves to stop the water.

4. Replace Existing Hoses With More Current and Durable Flexi Hoses

Flexi hoses have an excellent reputation for a reason, and your plumber will likely recommend that you replace your existing hoses with them. When speaking with your plumber, consider asking them for recommendations. They can provide you with options and may even be able to supply their own flexible braided hoses.

Because of the numerous advantages seamless steel tubing possesses over other tubing&#;apart from the added cost&#;seamless steel tubing is widely used in hydraulic systems. Seamless steel tubing is easier to bend than steel pipe, so it does not require the number of fittings and can be reused. High-volume applications are probably one of the only limited areas to the use of tubing.

Tubing size is measured on the outside diameter of the tube. All sizes are available in a variety of wall thicknesses. The application and use of tubing, (material, diameter and maximum pressure) will determine the wall thickness of the tubing used. Sizes range from 1&#;8 to 2 in. in fractional sizes.
Considering the application, internal pressures, weight, environmental conditions and whether you are going to use flared or flareless tubing are all considerations you must know to help you in material selection. Good quality tubing must be selected to ensure a good seal.

Tubing comes in a variety of materials, including:

• Seamless carbon steel, which is the most commonly used. It has a tensile strength to 47,000 psi.
• Stainless steel is used when external conditions require noncorrosive materials. It also has a tensile strength to 47,000 psi.
• Plastic can be used in low pressure applications.
• When selecting a material for your specific application, don&#;t focus only on the price tag. The manufacturer&#;s information is the most reliable and should be used when selecting the material based on allowable stress and working pressures.

Fittings
Tubing does not use threaded fittings. The fitting attachment is accomplished by either a component or another tube. The attachment is made by the following:

• Flared fittings are used primarily in low to medium pressure applications.
• SAE standard J533B covers specifications for both single and double flared (37° and 45° flare) tubing. Double flared tubing is used with thin walled tubing.
• SAE 37° angle is the standard angle used for hydraulic system tubing.
• SAE 45° angle is used with soft copper tubing for applications such as refrigeration, fuel lines, etc.
• The maximum wall thickness recommended by SAE standard should be checked prior to flaring a tube.
• Flareless Fittings, also commonly known as compression fittings, are used primarily in medium- to high-pressure applications.
• As system pressures increase, you require a thicker wall thickness. Higher pressures also affect the ability to use a flared type fitting.
  • Pressure capacity can be calculated using the following formula:
    • Pressure (P) = 2 x S x T / D,

Where
P &#; pipe internal pressure in psi
T &#; wall thickness
D &#; O.D. tube
S &#; stress on tube material in psi
Flareless type tubing fittings are available in
two common styles.

• Ferrule or Sleeve Type: The ferrule is used to seal against the tapered seat of the fitting and the tube. When tightening the nut a sealing pressure is felt on sealing surfaces causing the tube to deform
• O-ring type: Sealing is obtained by the installation of an internally mounted O-ring. The O-ring type uses a split ferrule to clamp the tube.
  It is important to remember to never mix from different manufacturers and always refer to the manufacturers specifications (torque recommendations) prior to installation.
• Welding fittings are used primarily in high pressure, vibration and fixed applications.
  Butt and sockets welds are both used to connect the fitting to the tube, so material type wall thickness and welding skills must be considered when using a welding fitting.

Flexible hose

• As stated previously, pipe and tubing are rigid fluid conductors and therefore not suitable when there is movement of one end of the conductor while the opposite end is fixed.

• The benefits of flexible hose over rigid pipe and tubing is that flexible hose is simple to route, withstands vibration and thermal expansion or contraction.
• Flexible hose consists of the following:
  • Inner tube
  • Reinforcement
  • Outer protective cover

The inner tube is made of either oil resistant synthetic rubber or thermoplastic material. Reinforcement amount and type is determined by the hose&#;s pressure rating. As the requirement of reinforcement increases from a single fiber/wire braid to multiple fiber/wire braids, the hose loses its flexibility. Outer protective cover is manufactured to be oil and weather resistant. Primarily, the outer protective cover is made of a synthetic rubber or thermoplastic material. The Society of Automotive Engineers (SAE) has set standards for hydraulic hose specifications. Most manufactures of hydraulic hose meets or exceeds SAEJ513 requirements.

Final note: Because the hose meets standards it is extremely important to carefully match the end fittings to the hose selected
