Meter pipes heating the dominant product; this is my company is the development of mineral insulated heating cable has been successfully applied in electric heating temperature steam cleaning pipelines, electric heating flue gas desulfurization project due to the heating of the cable housing is stainless steel protection. sets. Electrically insulating layer using mineral magnesium, nickel-chromium alloy heating wire resistance wire. So these conditions determine the maximum temperature of the heating cable to withstand 800 ℃ or more. I. Introduction mineral insulated heating cable mineral insulated heating cable is to use single or multiple alloy heating wire as a heat source, high purity, high temperature, fused magnesia as a thermal insulator crystallization, seamless stainless steel or brass as a continuous sheath, using a special manufacturing process is made. The place has a strong corrosive effect can be applied to PE or LSZH jacket. ● Stainless steel sheathed mineral insulated heating cable series stainless steel sheathed mineral insulated heating cables to meet the high temperatures and high heating power (up to 269W / m) needs. Sino-Japanese stainless steel sheath for electrical heating cable maximum withstand temperatures up to 600 ℃, the conductor resistance values ??range from 28000-19.2Ω / km, mineral insulated cables have excellent mechanical strength and corrosion resistance. ● copper sheathed mineral insulated heating cable series mineral insulated copper sheathed heating cables to meet the high temperatures and long pipeline heating needs. Sino-Japanese copper sheathing for electrical heating cable maximum withstand temperatures up to 250 ℃, the conductor resistance values ??range from 480-0.5Ω / km, or buried corrosion requirements of application, require heightened density polyethylene HDPE outer Sheath (MIHC), MIHC maximum temperature up to 90 ℃, mineral insulated cables have excellent mechanical strength. ● copper-nickel alloy sheathed mineral insulated heating cable sheathed mineral insulated copper-nickel alloy heating cables to meet the high temperatures and long pipeline heating needs. In Japan for the copper-nickel alloy electrical heating cable jacket to withstand temperatures up to a maximum 400 ℃, the conductor resistance values ??ranging from 28000-19.2Ω / km, mineral insulated cables have excellent mechanical strength, corrosion resistance
