Hot-applied waterproofing materials, such as non-curing rubber asphalt coatings, are sprayed or applied at elevated temperatures and must stay fluid from the heating tank to the spray gun. On a roof, in a basement excavation or on a tunnel and bridge deck, the hose is exposed to wind, cold, sun and rough handling, and any heat loss along the way shows up as thick, uneven coating and pump strain. JINGCHENG's waterproofing construction equipment hose is an electrically heated hose for all types of waterproofing construction equipment and non-curing spray equipment, heat resistant up to 230°C. Since 2013 JINGCHENG has worked long term with leading companies in the waterproofing equipment industry, and the hose has since gradually won a strong market position, earning high praise for its stability and durability in harsh weather and harsh construction environments.
Fast heat loss outdoors: low ambient temperatures and wind cool the coating inside an inadequately heated hose.
Rising viscosity: cooled material thickens, causing uneven spray patterns and extra load on the pump.
Rough job-site handling: hoses are dragged over concrete, membranes, edges and scaffolding.
Long working days: the hose has to keep a steady temperature hour after hour, day after day.
Braided heating elements surround the inner tube evenly, so the temperature difference along the inner wall is kept to a minimum and the coating reaches the gun at a consistent temperature.
High-insulation-efficiency materials are chosen with the hose surface temperature in mind. In cold or windy conditions this keeps heat inside the line, reduces energy demand on the machine and gives crews a safer outer surface to handle.
Over many years of supply to waterproofing equipment builders, the hose has developed a reputation for very high stability and durability under severe weather and difficult site conditions, which is the main reason equipment makers keep specifying it.
The temperature sensor can be Type J or Type K thermocouple, Ni120, PT100 or PT1000, matched to the control system of the spraying machine.

Data source: JINGCHENG 2025 Electrically Heated Hose Catalog. Heat resistance up to 230°C; higher temperature on request. 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.
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.
Material and temperature: tell us the coating you apply, for example non-curing rubber asphalt, and its working temperature (standard up to 230°C).
Size and length: select 1/2", 5/8" or 3/4" ID for your pump output and the hose length needed to reach the work area.
Electrical data: supply voltage, power per meter and the sensor type read by the machine controller.
Interfaces: thread standard at tank end and gun end (US, British or metric) and the connector pin layout.
Site practice: do not twist the hose, avoid sharp bends near fittings and protect it from sharp edges when it is dragged across the site.
Shenzhen Jingcheng High-Tech Co., Ltd. has made PTFE hoses and electrically heated hoses since 2005 and has supplied the waterproofing equipment industry since 2013. Every hose is built to the customer's machine, so send us your equipment, coating and fitting details for a tailored specification and quotation.
