Special industrial equipment frequently has to push hot, viscous media from a pump, melter or reactor to the point of use at high pressure. Two failure modes dominate such lines: the medium cools and thickens or solidifies inside the hose, or the hose itself cannot hold the system pressure once it is at temperature. JINGCHENG's special-industry connection hose is an electrically heated, high-pressure Teflon hose designed to remove both risks. The inner tube is made of Daikin PTFE (Teflon) from Japan, the pressure layer uses 304 stainless steel pressure wire, and uniformly braided heating elements keep the fluid at its set temperature along the whole length. The hose is heat resistant up to 230°C (higher on request) and can be built for working pressures up to 40 MPa or more as a custom design, for both domestic and imported special equipment.
Solidification and viscosity rise: resins, fats, oils and similar fluids freeze, solidify or thicken wherever the line loses heat
Inconsistent delivery: a temperature gradient along the hose changes viscosity and makes metering unstable
Pressure at temperature: many hoses lose pressure capacity when hot, leading to leakage or rupture
Heat loss and surface temperature: poorly insulated lines waste energy and create burn hazards around the machine
A heated, insulated and pressure-rated connection hose keeps the medium at a constant temperature from inlet to outlet while safely carrying the system pressure.
The medium contacts only Japanese Daikin PTFE (Teflon), a chemically inert, non-stick material suited to continuous high-temperature duty.
A 304 stainless steel pressure wire layer surrounds the inner tube and provides the high working and burst pressure needed on special equipment.
The heating layer is formed by evenly braided heating elements, which minimizes temperature differences on the inner wall and avoids both cold spots and local overheating.
Insulation materials with high insulating efficiency are selected with the outer surface temperature in mind, keeping heat in the fluid and the hose surface safer to work around.
The hose can carry a Type J or Type K thermocouple, Ni120, PT100 or PT1000 sensor so your controller holds the line at its set point; matching temperature controllers are available.
Every line passes three levels of assurance: routine checks by a testing agency, in-house inspection and supplier control. Together they verify the temperature resistance and pressure resistance of each hose before it ships.

Data source: JINGCHENG 2025 Electrically Heated Hose Catalog. Heat resistance up to 230°C; higher temperature and pressure available as custom builds. Confirm the rating at your operating temperature with our engineers when ordering.
Each JINGCHENG electrically heated hose is assembled to the buyer's specification. The catalog order form covers the following items:
Parameter | Options listed in the catalog |
|---|---|
Supply voltage | 380 Vac, 220 Vac, 110 Vac, 12 Vdc or other |
Temperature sensor | Type J thermocouple, Type K thermocouple, Ni120, PT100, PT1000 or other |
Hose length | 3 m, 4.5 m, 5 m, 6 m, 10 m or other |
Inner diameter | Φ8, Φ12, Φ16, Φ19, Φ25 mm or other |
Working pressure | 4 MPa, 10 MPa, 20 MPa, 35 MPa or other |
Heating power | 110 W/m, 150 W/m, 170 W/m, 200 W/m or other |
End fittings | US, British or metric threads, or other |
Wiring | Pin number, wire color and function at the controller end and the gun/tool end |
A typical code such as JCH-200-16-B-3X220-P2-8 is read as follows: 200 = working temperature 200°C; 16 = inner diameter Φ16 mm; B = inner tube type (B stainless steel corrugated tube, TB PTFE hose with stainless steel braid, T PTFE hose, X special material); 3X220 = supply (220 = 220 V single phase, 3X220 = three-phase four-wire 220 V); P2 = sensor (P2 PT100 two-wire, P3 PT100 three-wire, K Type K, J Type J, W no sensor, T special sensor); 8 = working pressure 8 MPa.
Ambient temperature -40°C to +55°C, relative humidity not above 85%
Atmospheric pressure 86 kPa to 106 kPa; voltage range 12 Vac to 380 Vac
No gases that corrode metal or damage insulation, no conductive media and no severe mold in the surroundings; other environments are handled as custom builds
Connect the hose strictly according to its technical data and the pin table delivered with it.
Never twist the hose sideways during or after installation; torsion can lead to leakage, flow loss, hose damage or fire.
Keep bends generous; over-bending can damage the hose and cause short circuit, leakage or fire.
Let only authorized, trained operators handle the hose, ideally a dedicated team.
Unauthorized modification or adjustment voids the warranty.
For any situation not covered by the instructions, contact JINGCHENG engineers for installation guidance.
