Overview of Electric Heat Tracing Pipeline
● Stainless Steel Electric Heat Tracing Pipeline
The stainless steel sheathed series heating cables can meet the requirements of high temperature conditions and high heating power (up to 300W/m). The maximum withstand temperature of the electric heat tracing pipeline can reach 800°C, and the conductor resistance range is from 28000 to 19.2 Ω/km. The electric heat tracing pipeline has excellent mechanical strength and corrosion resistance.
● Copper Sheathed Electric Heat Tracing Pipeline
The copper sheathed series heating cables can meet the requirements of high temperature conditions and long-distance pipeline heat tracing. The maximum withstand temperature of the copper sheathed electric heat tracing pipeline can reach 250°C, and the conductor resistance range is from 480 to 0.5 Ω/km. For applications requiring corrosion protection or buried installation, the electric heat tracing pipeline has excellent mechanical strength.
● 825 Alloy Sheathed Electric Heat Tracing Pipeline
The copper-nickel alloy sheathed electric heat tracing pipeline can meet the requirements of high temperature conditions and long-distance pipeline heat tracing. The maximum withstand temperature of the copper-nickel alloy sheathed electric heat tracing pipeline can reach 400°C, and the conductor resistance range is from 28000 to 19.4 Ω/km. The
electric heat tracing pipeline has excellent mechanical strength and corrosion resistance.
