In polyurethane processing, the temperature of each component is a process parameter, not a side effect. Each component is conditioned in the machine, but the hose that carries them to the laminating head, the mixing point or the next unit can undo that work in a few meters if it lets the material cool. The JINGCHENG Heat-Traced Polyurethane Component Line is the dedicated heated pipeline we build for polyurethane equipment. It is widely used on all kinds of laminating machines and on single and two-component polyurethane compounding and connecting equipment, with a heat resistance of up to 180°C and higher temperatures available on request. Over many years, stable quality and complete customer service have earned this line a large base of long-term customers.
A polyurethane component that leaves a conditioned tank at the right temperature still has to travel through the hose. Along the way:
Heat escapes through the hose wall, so the outlet temperature falls further the longer the line is
Viscosity rises as the material cools, which changes the flow the machine sees at the outlet
Two components react differently to the same heat loss, so their flow behavior can drift apart on two-component systems
Fittings and hose ends act as heat sinks, creating local cold zones where material can build up
A heat-traced component line replaces the heat lost through the wall along its whole length, so the material arrives at the point of use as it left the supply.
The heating layer consists of uniformly braided heating elements wound around the inner hose. Because the heating is distributed evenly over the circumference and the length, temperature differences on the inner wall are minimized and no section of the line runs noticeably hotter or colder than the rest.
The insulation is made of high-insulation-efficiency materials, selected with the outer surface temperature in mind. Less heat is lost to the surroundings, the controller needs less power to hold the set point and the outside of the hose stays at a more comfortable temperature near operators.
Each line can carry its own temperature sensor (Type J or Type K thermocouple, Ni120, PT100 or PT1000), wired to the pin layout of your temperature controller. On two-component equipment, the line for each component can be specified and controlled independently.
Up to 180°C heat resistance for polyurethane processing, higher on request

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.
Send your inquiry by phone, fax or the website inquiry form.
Our engineers confirm the most suitable specification as the basis for quotation.
You receive a quotation and confirm with a purchase order.
The hose is produced in our factory to the confirmed specification.
Every hose is inspected for defects and packed.
The order is shipped to your designated address.
List every component line: for each one, give the material, the set temperature (up to 180°C as standard) and the flow it must deliver.
Match bore to flow: pick an inner diameter between 1/4" and 1" per line; the two component lines do not have to be the same size.
Measure the real route: take the length from the conditioning unit to the application point, including bends around the machine frame.
Define the controls: supply voltage, power per meter and the sensor type and pin layout each controller channel expects.
Specify both ends: US, British or metric threads at the machine end and the head end.
Can the two component lines have different sizes or lengths? Yes. Every line is built to order, so each component can have its own inner diameter, length, sensor and connector.
Is 180°C the absolute limit? It is the standard catalog rating for the polyurethane hose; higher temperatures can be built on request after our engineers review your process.
Shenzhen Jingcheng High-Tech Co., Ltd. has manufactured PTFE hoses and electrically heated hoses since 2005. Send us your polyurethane system, machine layout and controller details, and our engineers will propose a matching line set and quotation.
