JINGCHENG Waterproofing Construction Equipment Hose is an electrically heated hose for all types of waterproofing construction and non-curing spray equipment, heat resistant up to 230°C and supplied to leading waterproofing equipment makers since 2013. This page works through the spraying problems crews see most often on cold or windy sites — thick spray, pump strain, leaks near fittings and wrong temperature readings — and links each one to the hose construction and catalog figures that prevent it.
Hot-applied waterproofing — for example non-curing rubber asphalt coating — depends on material that stays fluid from the heating tank to the spray gun. On roofs, basements, tunnels and bridge decks the delivery hose is the part most exposed to wind, cold and rough handling, so many on-site spraying problems can be traced back to it. This guide lists the symptoms crews report most often, what usually causes them in the hose, and which catalog figures help prevent them.
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 (higher on request). JINGCHENG has worked long term with leading companies in the waterproofing equipment industry since 2013, and the hose has earned a strong reputation for very high stability and durability in harsh weather and harsh construction environments.
Likely cause: the coating loses heat in the hose before it gets to the gun, so viscosity rises and atomization suffers.
What prevents it: a hose that heats along its full length and holds the heat in. The heating layer of the JINGCHENG hose is made of uniformly braided heating elements, which minimize the temperature difference along the inner wall, and high-efficiency insulation is selected with the hose surface temperature in mind. Also confirm the set point you need against the 230°C rating.
Likely cause: a cold section, or a bore that is too small for the required output, raises the resistance in the line.
What prevents it: choose the bore from the catalog table rather than from habit. The catalog offers 1/2", 5/8" and 3/4" inner diameters; the larger bores carry more material at lower working pressure ratings, as the table below shows.
Likely cause: the hose has been twisted sideways or bent tighter than its minimum bend radius when it is dragged over parapets, scaffolding or excavation edges.
What prevents it: respect the bend radius — 150 mm at 1/2", 180 mm at 5/8" and 260 mm at 3/4" — and never twist the hose. Lateral twisting and sharp bends can cause leakage, flow loss, hose damage, short circuit or fire.
Likely cause: the hose sensor does not match the controller on the spraying machine, or it is wired to the wrong pins.
What prevents it: order the sensor your controller reads — Type J or Type K thermocouple, Ni120, PT100 or PT1000 — and wire the hose strictly according to the pin table supplied with it.
The waterproofing equipment hose is listed in three sizes:
1/2" — 15.9 mm OD, working pressure 118 bar (1704 psi), burst 470 bar (6815 psi), bend radius 150 mm
5/8" — 19 mm OD, working pressure 88 bar (1269 psi), burst 350 bar (5075 psi), bend radius 180 mm
3/4" — 22.6 mm OD, working pressure 85 bar (1234 psi), burst 340 bar (4930 psi), bend radius 260 mm
Inner Diameter (inch) | Outer Diameter (mm ±0.2) | Working Pressure (bar) | Working Pressure (psi) | Burst Pressure (bar) | Burst Pressure (psi) | Min. Bend Radius (mm) |
|---|---|---|---|---|---|---|
1/2" | 15.9 | 118 | 1704 | 470 | 6815 | 150 |
5/8" | 19 | 88 | 1269 | 350 | 5075 | 180 |
3/4" | 22.6 | 85 | 1234 | 340 | 4930 | 260 |
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.
The catalog operating environment for JINGCHENG electrically heated hoses is an ambient temperature of -40°C to +55°C, relative humidity not above 85%, atmospheric pressure from 86 kPa to 106 kPa and supply voltage from 12 Vac to 380 Vac. The surroundings should not contain gases that corrode metal or damage insulation, conductive media or severe mold; other environments are handled as custom builds.
Coating and temperature: name the material, for example non-curing rubber asphalt, and its spraying temperature (standard up to 230°C).
Bore and length: select 1/2", 5/8" or 3/4" for the pump output; catalog lengths are 3 m, 4.5 m, 5 m, 6 m, 10 m or other.
Electrical data: supply voltage (380 Vac, 220 Vac, 110 Vac, 12 Vdc or other), rated power (110, 150, 170 or 200 W/m or other) and sensor type.
Interfaces: US, British or metric threads at the tank end and gun end, and the connector pin layout.
A model code such as JCH-200-16-B-3X220-P2-8 summarizes the build: 200°C, Φ16 mm, inner-tube type B, three-phase four-wire 220 V, PT100 two-wire, 8 MPa.
Send your spraying machine model, coating, temperature, hose length and fitting details. JINGCHENG engineers will propose a waterproofing equipment hose specification and quotation built for your sites.
