High-Temperature Inert Gas Hose for Flexible Connections in Glass Manufacturing Equipment

Glass production lines often combine extremely rigid machinery with process areas exposed to elevated temperatures.

Most gas distribution systems can be installed using rigid metal piping.

However, rigid pipe is not ideal at every connection point.

A production machine may require a short flexible transition between the main gas line and:

• Moving equipment

• Adjustable components

• Process modules

• Replaceable assemblies

• Difficult-to-align connection points

This is where a specialized high-temperature flexible hose becomes useful.

Jingcheng’s high-temperature inert gas hose is designed primarily for glass production lines where gas must be delivered near elevated-temperature equipment.

The catalog specifies a maximum temperature of approximately 230°C and several hose diameters from 1/4" to 1".

Why Glass Production Lines Need Flexible Gas Connections

A rigid gas pipe works well over long fixed distances.

But the final connection to the machine can be more complicated.

Machine components may not align perfectly with the main supply line.

A short flexible hose can compensate for limited differences in:

• Height

• Angle

• Position

• Installation tolerance

This can simplify final equipment assembly.

It can also make maintenance easier when components need to be removed and reinstalled.

Useful for Equipment Retrofit Projects

Glass production equipment may remain in operation for many years.

During its service life, factories may replace:

• Valves

• Gas control units

• Burners

• Process modules

• Distribution manifolds

The replacement component may not have exactly the same port position as the original.

Rebuilding an entire rigid gas line can be time-consuming.

A customized flexible hose provides another way to bridge the connection between the existing pipeline and the new equipment.

High-Temperature Environment Is the Main Design Challenge

The catalog indicates that this hose is used in glass production lines because the operating temperature is relatively high.

The hose therefore needs to function not only with the gas inside but also with the surrounding thermal environment.

The source product specifies maximum temperature capability up to approximately:

230°C

The actual allowable temperature for a customized assembly should be confirmed according to the complete hose design, fittings and installation conditions.

Heated Construction Helps Maintain the Required Thermal Condition

The product belongs to Jingcheng’s high-temperature hose family and uses an integrated heating structure.

The heating elements are arranged around the hose to provide more uniform heat distribution.

This helps reduce temperature differences along the material path.

For applications where the gas line needs controlled heating, the hose can be customized according to required temperature and electrical conditions.

Insulation Reduces Unnecessary Heat Loss

Heating without insulation would waste energy.

The hose therefore also uses thermal insulation around the heated section.

The insulation layer helps reduce heat transfer to the surrounding environment and supports more stable internal temperature conditions.

For high-temperature machinery, this becomes especially important when the hose passes through areas with changing ambient conditions.

Pressure Capability Depends on Diameter

The catalog provides several hose sizes.

Selected working pressure values include approximately:

• 1/4" — 173 bar / 2,501 psi

• 5/16" — 158 bar / 2,284 psi

• 3/8" — 135 bar / 1,958 psi

• 1/2" — 118 bar / 1,704 psi

• 5/8" — 88 bar / 1,269 psi

• 3/4" — 85 bar / 1,234 psi

• 1" — 75 bar / 1,088 psi

These values show that the hose family provides substantial pressure capability.

However, the final operating pressure should always be evaluated together with temperature.

Smaller Diameter Hoses Offer Tighter Routing

The minimum bending radius increases as hose size becomes larger.

For example, the catalog lists approximately:

• 1/4" — 30 mm

• 5/16" — 40 mm

• 3/8" — 60 mm

• 1/2" — 150 mm

• 1" — 300 mm

For compact glass-processing machinery, this means the smallest suitable internal diameter may provide easier installation.

However, diameter must still be large enough to meet the required gas flow.

Flexible Connections Improve Maintenance Access

Maintenance teams often need to remove process components for inspection.

Rigid pipe connections can make this more difficult because the components must return to nearly the exact original position.

A flexible hose provides limited installation tolerance.

This can simplify:

• Component replacement

• Valve service

• Module removal

• Machine adjustment

This is especially valuable where access around the equipment is limited.

Avoid Using Excessively Long Flexible Sections

A flexible hose is useful, but it does not need to replace every rigid line.

For many glass production applications, a better configuration is:

Rigid Gas Supply Line → Short Flexible High-Temperature Hose → Process Equipment

This approach combines the stability of rigid piping with the installation flexibility of the hose.

It also reduces unnecessary hose length.

Customized End Connections

Glass production equipment may use different interfaces.

Jingcheng can customize:

• Hose diameter

• Hose length

• End fittings

• Thread standards

• Electrical heating parameters

• Sensor configuration

• Connector type

For replacement projects, customers can provide an existing hose or installation photographs.

Typical Applications

Potential applications include:

• Glass production lines

• Inert gas delivery equipment

• Heated gas connections

• Industrial furnace-related equipment

• High-temperature process machinery

• Gas supply module connections

• Production-line retrofit projects

The exact gas compatibility should be confirmed according to the specific application.

Conclusion

Rigid pipe remains the preferred solution for many fixed gas distribution systems.

But around high-temperature glass production equipment, a short flexible connection can solve alignment, retrofit and maintenance problems that rigid piping cannot easily accommodate.

Jingcheng’s high-temperature inert gas hose provides a customizable connection for glass machinery requiring elevated-temperature gas delivery and flexible installation.

The best design should balance gas flow, hose diameter, temperature, pressure, bending radius and connection geometry.
