When to Use flexible Steel Hose – 6 Factors to Consider

When to Use flexible Steel Hose – 6 Factors to Consider

Supply SS Metallic Hose: Application: Ideally suited to high pressure, High temperature and corrosive applications, flexible metal hoses, steam, compressed air, petro-chem and vacuum; Size Range: 6mm-300mm; Temperature: -270°C to 600°C; Cam and Groove Female Coupler; Cam and Groove Male Adaptor; Female Union; Fixed Male (BSP,NPT); Swivel Flange (ANSI,Table D or E); Fixed Flange (ANSI,Table D or E)

Many people ask this question that why to use the steel hose. Read the following; the answer is given below:

There are several types of hose available now on the market. Types include rubber, composite, PTFE, steel, and fabric. Typically, a flexible steel hose is used when no other construction will work. In simple words, a steel hose is used as a last resort. The steel hose type to buy depends on the application for which one can use a steel hose. Generally, six factors that make you attentive to consider using steel hose:

Temperature Extremes

Suppose the media’s temperature going through the hose or the surrounding atmospheric temperature is very cold or too hot. In that case, steel can be the only material that can withstand the temperature extremes.

Fire Safety

Other hose types melt when exposed to fire. In contrast, steel hose maintains its integrity up to 1200 degree F. Flexible corrugated hoses are generally all-steel if a fitting contains a non-steel seal, making them naturally fire-resistant. Low infusion and fire resistance make a corrugated flexible steel hose the preferred option for charge loading and unloading applications or other applications where the hose needs to expose to an open flame.

Chemical Compatibility

Steel hose can handle a wide variety of chemicals than most of the other hose types. If the hose exposes to aggressive chemicals, internally or externally, the flexible steel hose is the best option. Stainless steel reveals good resistance to several common chemicals, and special alloys use for added corrosion resistance.

Permeation Concerns

The non-steel hose is susceptible to having gases infuse through the hose wall and into the air. On the other hand, a flexible steel hose does not allow permeation when adequately fabricated. If comprising the gases inside the hose is essential, a steel hose might be required.

Possible for Catastrophic Failure

When a steel hose flops, it typically develops small holes or cracks. Other hose types tend to create larger cracks or come apart ultimately. In non-steel hoses, barbed fittings are usually seized onto the hose ends using crimped collars. As steel hose welds fittings, retention problems are approximately non-existent. If an unexpected failure of the hose can be catastrophic, a steel hose may help minimize the effects of a loss by leaking the product at a low rate.

Abrasion and Over bending Concerns

A flexible steel hose can be used as a defensive cover over wires or even other hoses to prevent scratch and bend. Stripwound hose can be abrasion-resistant, making it ideal for protecting the corrugated hose from either external damage or abrasive media. Stripwound hose can apply to the external of a corrugated hose to avoid it from bending. Bending a corrugated hose is a way to fatigue the steel hose of an assembly disproportionately. However, the strip wound hose cannot be overbent without pulling the hose apart, making it an excellent bend restrictor installed on a corrugated body.
