Special equipment often has to move hot, pressurized fluids between a pump, a melter or a reactor and the point of use. If the transfer line cools down, viscous media thicken or solidify, flow becomes unstable and the line can block. If the hose cannot hold pressure at temperature, the whole system is at risk. JINGCHENG's Special Equipment Connection Hose is an electrically heated hose built for exactly this duty: it heats and insulates the fluid along its full length, uses a Daikin PTFE (Teflon) inner tube with 304 stainless steel pressure wire, and is rated for heat resistance up to 230°C, with working pressure up to 40 MPa or higher on custom builds.
Unheated or poorly insulated transfer lines cause recurring problems on high-temperature, high-pressure equipment:
Cold spots: resins, fats, oils and other viscous fluids solidify, freeze or increase in viscosity where the line loses heat
Unstable flow: temperature differences along the hose change viscosity and make dosing or delivery inconsistent
Pressure failure: hoses that are not designed for pressure at high temperature can leak or burst
Safety and surface temperature: a hot line with poor insulation is a burn and energy-loss problem around the machine
An electrically heated connection hose keeps the medium at a constant, controlled temperature from end to end while carrying the system pressure.
The inner tube is made of Daikin PTFE (Teflon) from Japan, which is chemically inert, non-stick and suitable for high-temperature service. The pressure-bearing layer uses 304 stainless steel pressure wire, which gives the hose its high working and burst pressure.
The heating layer is made of uniformly braided heating elements, which minimizes temperature differences across the inner wall of the hose. Around it, JINGCHENG uses materials with high insulation efficiency, chosen with the outer surface temperature in mind, so that heat stays in the fluid instead of being lost to the surroundings.
A built-in temperature sensor (Type J or Type K thermocouple, Ni120, PT100 or PT1000, as specified) reports the hose temperature to your controller, so the line can be held at its set point. Matching temperature controllers can also be supplied.
Heat resistance up to 230°C (higher temperatures available on request)
Working pressure up to 40 MPa or higher on customized builds
Daikin PTFE inner tube with 304 stainless steel pressure wire
Uniformly braided heating elements for an even inner-wall temperature
High-efficiency insulation designed around the hose surface temperature
Three levels of quality assurance: routine checks by a testing agency, in-house inspection and supplier control, so that every line's temperature and pressure resistance is verified
Built to order: voltage, sensor, length, inner diameter, power and fittings are specified per project
The Special Equipment Connection Hose is designed for domestic and imported special equipment that runs high-temperature, high-pressure pipelines. Typical uses include:
Hot fluid transfer on special machinery: connecting pumps, melters, tanks and dispensing heads
Viscous media lines: keeping resins, fats, oils and other viscous fluids from solidifying or thickening
Insulated hot-fluid conveying systems: heated and insulated connections between process equipment
Retrofit and replacement lines: custom connection hoses for imported equipment, built to the original parameters

JINGCHENG heated hoses are identified by a model code such as JCH-200-16-B-3X220-P2-8:
200: working temperature in °C (200 = 200°C)
16: hose inner diameter in mm (16 = Φ16)
B: inner tube material (B = stainless steel corrugated tube; TB = PTFE hose with stainless steel braid; T = PTFE hose; X = special material)
3X220: working voltage (220 = 220 V; 3X220 = three-phase four-wire 220 V)
P2: temperature sensor (P2 = PT100 two-wire; P3 = PT100 three-wire; K = Type K thermocouple; J = Type J thermocouple; W = no sensor; T = special sensor)
8: working pressure in MPa (8 = 8 MPa)
Ambient temperature: -40°C to +55°C
Relative humidity: not more than 85%
Atmospheric pressure: 86 kPa to 106 kPa
Voltage range: 12 Vac to 380 Vac
The surrounding medium should not contain gases that corrode metal or damage insulation, or conductive media, and severe mold must not be present. For special environments, contact us for a customized hose.
Wire the hose according to its technical parameters and the pin table supplied with it.
Do not twist the hose sideways during or after installation; lateral twisting can cause leakage, flow loss, hose damage or fire.
Avoid sharp bends; bending the hose too tightly can damage it and cause short circuit, leakage or fire.
The hose should be operated only by authorized and trained personnel, ideally the same dedicated operators.
Unauthorized modification or adjustment of the hose voids the warranty.
If you meet a problem not covered by the instructions, contact us so that our engineers can guide the installation.
