Definition of Steel Wire Spiral Hose

Steel wire spiral hose consists of two or more sets of helically wrapped high tensile wire. The purpose of this hose is to be used in very high stress, high pressure, and high impulse settings. The psi rating is the same across the board when it comes to id sizes.

Benefits of Steel Wire Spiral Hose

The durability of steel wire spiral hose is excellent, mainly due to their special structure and material. Steel wire spiral hose are usually composed of an inner rubber layer, a reinforcing layer, and an outer rubber layer. The inner rubber layer is directly in contact with the oil and requires excellent wear resistance, oil resistance, and temperature resistance; the reinforcement layer is the skeleton of the rubber hose, usually woven with high-strength fibers or steel wires, which can withstand the pressure and tensile force of the oil; the outer adhesive layer plays a role in protecting the reinforcement layer and preventing corrosion.

Spiral steel wire wound hose is a new type of composite pipe that is resistant to high temperature, oil and corrosion.

The inner layer of the spiral steel wire wound hose is a metal layer, and the outer layer is a PVC coating, which has excellent mechanical properties and anti-aging properties.

Spiral steel wire wound hose has high bearing capacity and good fatigue resistance.

The spiral steel wire wound hose can be bent arbitrarily and adapted to different working environments.

The service life can reach more than 50 years (using high temperature resistant coating).

It can reduce the requirements of the pipeline system on the medium pressure and temperature, reduce the loss of the pipeline system and improve the flow and pressure efficiency.

What Material Is Steel Wire Spiral Hose Made Of?

PVC is one of the amorphous plastics. Nevertheless, this material is characterized by excellent media resistance. Hoses made of this material are suitable for almost any environment and for almost any application - unless solvents (aromatics, esters, ketones, CHCs) are used. PVC is an inexpensive, versatile material.
However, the temperature resistance as well as the abrasion resistance of PVC are significantly worse than those of polyurethane. In addition, the material can become brittle over time due to migrating plasticizers, which can lead to premature hose failure.

What You Should Know When Use Steel Wire Spiral Hoses?

During the manufacturing process of steel wire spiral hoses, special rubber with good oil and climate resistance is used, and copper plated steel wires are used for reinforcement. These characteristics enable steel wire spiral hoses to operate stably in hydraulic systems of mining equipment and meet various needs.

Despite the excellent durability of steel wire spiral hoses, it is still necessary to pay attention to appropriate maintenance and upkeep during actual use to extend their service life. For example, it is necessary to regularly check the wear level of hydraulic hoses and replace them in a timely manner if any problems are found; avoid using sharp objects with hydraulic hoses to prevent damage; ensure the correct installation of hydraulic hoses to avoid tilting and other situations; regularly clean the hydraulic hose of the coal mine, maintain its internal cleanliness, and replace the sealing ring at appropriate times.

Handling and Shipping Precautions for Steel Wire Spiral Hose

When transporting steel wire spiral hoses, the hoses must be placed round or flush in the carriage, and other goods should not be stacked on the hoses to prevent frictional damage to the hoses.

In the compartment of the rubber hose, acid, alkali, oil and organic solvent should not be placed.

When handling nylon resin tubes with metal spirals, handle them with care to prevent damage.

Store in the open-air cargo yard or on the platform or on the wharf. The site must be flat, the rubber hoses should be laid out flat, and covered with tarpaulins.

Storage should avoid sunlight, rain and snow, keep clean, prevent contact with goods that affect the quality of the hose, such as acids, alkalis, oils and organic solvents, and keep away from the heating device 1 meter away.

During storage, the temperature in the warehouse should be kept between -15–40°C, and the relative humidity should be between 50–80%.

When storing, it should be laid flat. The stack of coiled rubber hoses should not exceed 1.5 meters, and the stack of nylon resin tubes stored flat should not exceed 1 meter. During storage, it should be turned upside down once a season.

How to Avoid Steel Wire Spiral Hose Bursting?

Have you ever encountered the phenomenon of sudden hose burst when you use steel wire spiral hose? If you have encountered any impact on your personal safety? Why do steel wire spiral hoses burst and delaminate? Next, let us analyze why steel wire spiral hoses burst? Let our personal safety be guaranteed .

Reason 1: The reason for the bursting of the steel wire spiral hose may be that the quality of the steel wire spiral hose is not good. The reason for the poor quality is that too much calcium powder is added to the raw material, which leads to various coefficients such as flexibility and burst pressure of the steel wire spiral hose. Linear decrease. When using a steel wire spiral hose, the steel wire spiral hose will bulge a large bag and stop working in time, otherwise the pipe will explode, which will have a great impact on personal safety.

Reason 2: When you buy a steel wire spiral hose, you must pay attention to the burst pressure of the steel wire spiral hose and the working pressure of the place you want to use. When the working pressure exceeds the burst pressure of the steel wire spiral hose itself, delamination and tube burst will occur the phenomenon.

Ultimate FAQ Guide to Hoses

Q: What is a steel wire spiral hose?

A: Steel wire spiral hose — also known as one or two wire — features a braided wire reinforcement and is constructed of synthetic rubber or AQP elastomer, while spiral hose — also known as four or six wire — feature wires stacked on top of each other, not threaded together.

Q: What is the difference between braided and steel wire spiral hose?

A: Braided hoses are more commonly used in high pressure applications, and steel wire spiral hoses are typically used in very and extremely high pressure and high impulse applications. The braid construction allows for more flexibility and a tighter minimum bend radius.

Q: Are steel wire spiral hoses better?

A: Because a steel wire spiral 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.

Q: What material is steel wire spiral hose made of?

A: Nevertheless, this material is characterized by excellent media resistance. Hoses made of this material are suitable for almost any environment and for almost any application - unless solvents (aromatics, esters, ketones, CHCs) are used. PVC is an inexpensive, versatile material.

Q: How long do steel wire spiral hoses last?

A: They should be changed every five to eight years, though you may only need to change them when replacing an appliance. On the other hand, rubber hoses need to be replaced every five years or even sooner, depending upon wear and tear.

Q: What is a steel wire spiral hose used for?

A: Steel wire spiral hoses are dependable and tough high-pressure hydraulic hoses that will get heavy duty jobs done safely and efficiently. They are popular in industries such as construction, mining, agriculture, highway maintenance, and any application that deals with high peak pressures and rigorous operating conditions.

Q: What is the difference between steel wire spiral hose and braided hose?

A: Steel wire spiral hose consists of many layers of steel wires, making it very rigid. It isn't easy to bend this Hose because it has less flexibility. Braided Hose is very flexible due to its interlocking design. You can bend this Hose very easily.

Q: Are steel wire spiral hoses better than rubber?

A: Steel wire spiral hoses are generally more flexible than stainless steel hoses, which can make them easier to work with in tight spaces. Stainless steel hoses are generally more durable than rubber hoses, which can make them a better choice for high-pressure and high-wear applications.

Q: What is the bend radius of a steel wire spiral hose?

A: For example, a typical 1/4in. ID 1-wire braided hose (rated for 3200 psi) has a bend radius of 1.5 inches. The same construction hose in 1-in. ID (rated for 1300 psi) has a bend radius of 5.5 inches.

Q: How do you measure the diameter of a steel wire spiral hose?

A: If you don't have a calliper at hand, there is another way to measure the diameter. Determine the circumference of the rope with a small thin string or whipping twine. Measure the length of the string with a ruler and divide the number by π (3.14159). This should give you the diameter of the rope.

Q: How do you cut a steel wire spiral hose?

A: • Set the blade at a right angle to the hose and cut the plastic part between the steel wiring.
• When the plastic is cut, pull gently on both hose lengths to expose the wire.
• Then, use pincers to cut the wire.

Q: What is the difference between braided and steel wire spiral hose?

Q: What is the best way to cut steel wire spiral hose?

A: Heavy-duty steel pipe and tube cutters are usually the easiest to use, but for tight spaces, an angle grinder or reciprocating saw may be needed. When using a metal pipe cutter, align the tool around the marked place on the galvanized pipe and rotate so that the wheel cuts deeper into the pipe until severed.

Q: What is steel wire spiral hose guard?

A: High-strength, resilient spiral guard protects hose and cable with superior anti-crush perfor- mance. Exceptionally smooth facing and rounded edges prevent. Spiral guard from getting caught on rough surfaces, as. Sleeves often can. No cutting of hose cover or injuries of staff.

Q: How do you store a steel wire spiral hose?

A: An inexpensive and easy way to store a coiled hose is to stick a pvc (polyvinyl chloride) pipe securely in the ground, then slide the coils over the top. You could also use a sturdy wooden stake, which could be painted or left natural, or a copper pipe, which will age to a beautiful patina.

Q: What is mining hose?
