EPI Expands Full‑Range Electric Heat‑Tracing Cable Portfolio for Global Petrochemical and Hazardous‑Area Process Thermal Management

Modern petrochemical operations face persistent risks: pipeline freezing, fluid viscosity rise and solidification under frigid ambient conditions, which may trigger pipeline blockage, process shutdown and potential safety hazards. Hazardous classified zones impose extra strict requirements on anti‑explosion, anti‑corrosion and long‑term operational stability for heat‑tracing equipment. EPI’s multi‑technical heat‑tracing cable system covers diverse working‑condition demands from general pipeline insulation to high‑temperature corrosive environments.

Its self‑regulating heating‑cable family includes mainstream DBR‑15‑220 and DBR‑25‑220 medium‑temperature models. Relying on conductive‑polymer PTC core material, these cables automatically adjust power output according to surface temperature, avoiding local overheating risks and permitting overlapping installation for complex pipeline layouts. They serve routine freeze‑protection and temperature‑holding for oil refinery pipelines and chemical storage auxiliary loops.

For heavy‑duty high‑risk sites, the 60W/M anti‑corrosion explosion‑proof heating cable adopts enhanced fluoropolymer outer sheath, adapted to strong‑acid, strong‑alkali and explosive hazardous working zones, suitable for crude‑oil transmission pipelines and chemical storage tank thermal preservation. Three categories of constant‑wattage heating tapes‑‑parallel constant‑power, series constant‑power and silicone‑coated constant‑wattage variants‑‑provide stable fixed‑power heat output. They fit long‑distance petrochemical pipeline tracing and constant‑temperature protection for compressor equipment. MI mineral‑insulated heating cables realize ultra‑high‑temperature continuous service, deployed for high‑temperature reaction pipework and flue‑gas pipeline thermal insulation inside large ethylene plants.

EPI also develops scenario‑specific infrastructure heating cables for industrial park auxiliary facilities. 36V basic‑type medium‑temperature garage‑floor snow‑melting heating cable and low‑temperature outdoor‑driveway de‑icing heating belt resolve ice‑jamming troubles for factory access roads and drainage channels. Tunnel fire‑protection‑pipe anti‑freeze heating cable features waterproof and pressure‑resistant construction, specially built for underground chemical‑transport tunnel fire‑pipe freeze‑proofing. All core industrial products comply with international explosion‑proof and electrical safety standards, supporting global EPC contractors and end‑users to reduce unplanned downtime and improve process‑site safety performance.
