RAYCHEM BTV-4-CT Constant Wattage Heat Trace Cable 4W/m

The nVent RAYCHEM BTV-4-CT is a series-resistance constant-wattage heat trace cable delivering a uniform 4 W/m throughout the full circuit length, regardless of pipe temperature or ambient conditions. Unlike self-regulating cables, the BTV constant-wattage design uses a nickel-chromium resistance element wound around a glass-fibre core, providing a truly fixed heat output that is independent of temperature — a characteristic that makes BTV cables essential for maintaining precise process temperatures at specific setpoints, particularly when fluid properties demand an exact minimum temperature rather than merely freeze protection. The BTV-4-CT is FM-approved for Class I, Division 2 / Zone 2 hazardous area installation with appropriate connection hardware, and the modified polyolefin jacket resists hydrocarbons, water, and UV radiation, ensuring long service life in both covered and uncovered outdoor pipeline installations across Saudi Arabia's harsh desert climate.

The BTV series delivers precise and consistent power output which is critical for applications where process fluids must be maintained within a narrow temperature window. Saudi Aramco's sulphur solidification and handling systems are a prime example: liquid sulphur must be held between 119°C and 149°C to remain fluid for transport and molding, and any deviation from this window causes immediate solidification or decomposition. The BTV-4-CT is deployed on sulphur transport lines from ARAMCO and SABIC sour gas plants throughout the Eastern Province, where the constant heat output — combined with thermostat control — maintains liquid sulphur within this tight process window 24 hours a day, 365 days a year. Similar applications are found on phenol and naphthalene product lines at SABIC affiliates in Jubail, where solidification at ambient temperature requires constant heat input to maintain product mobility.

For longer pipeline circuits requiring higher voltage to achieve practical circuit lengths, the BTV series is available in 240 V configurations reaching circuit lengths up to 150 m, making it suitable for the longer pipe runs found in ARAMCO's onshore oil gathering fields and tank farm interconnections. The constant power output simplifies energy accounting for SEC reporting and ISO 50001 energy management systems at industrial facilities — a growing requirement for Vision 2030 industrial zone tenants. The BTV-4-CT's straightforward heating element construction also means that field repairs — when a section is damaged by mechanical impact — require only a simple resistance check and splice kit, reducing repair time and cost compared to more complex heating cable technologies.

Razz Middle East supplies the complete RAYCHEM BTV product range including all gauges, voltage variants, and circuit lengths, with connection kits, end seals, and thermostat controllers from local stock. Our team holds SAES-L-310 project design experience and can provide full BTV system design documentation, approval drawings, and commissioning test records for Saudi Aramco, SABIC, MARAFIQ, and SWCC projects. Heat trace panel design, cable schedule preparation, and material take-off packages are provided as part of our project engineering service.
