MI heating cable|MI heat trace cable uses single or multiple alloy heating wires as heat source, high purity, high temperature, fused crystalline magnesium oxide as thermal insulator, seamless continuous stainless steel or copper tube as sheath, adopts Manufactured by special production technology. The stainless steel sheathed mineral insulated heating cable can meet the needs of high temperature conditions and high heating power (up to 269W/m). The armored mineral insulated heating cable is suitable for antifreeze and heat preservation and heating of the process medium in the industrial or construction field. Especially for pipelines that require high output power or need to withstand high-temperature steam purging, MI mineral insulated heating cables can show excellent characteristics in environments that require anti-corrosion and explosion-proof.

MI heating cable|MI heat trace cable Features
Since MI mineral insulated heating cable is made of metal and inorganic insulating materials, it has significantly different advantages than other heating cables or heating cables made of plastic insulation. Due to its special structure, it has the following characteristics:
1. Because its components are all composed of non-combustible inorganic substances, the product is fireproof, flame-retardant, and does not generate toxic gases. Because the heating cable has a reliable metal tube seal and good grounding, it is especially suitable for various explosion-proof places.
2. Because the magnesium oxide insulating material can remain stable when the temperature is as high as 550℃. Therefore, the operating temperature limit of the heating cable itself is the highest temperature that the core and metal outer sheath can withstand.
3. The insulation layer of the product, magnesium oxide, is an inorganic substance, and the core and outer sheath are both made of metal, so the aging problem is fundamentally solved, and the service life of the heating cable is greatly extended. The service life can reach several decades under specified conditions.
4. The product adopts different outer sleeves, which can withstand the erosion of oil solvents and most acids, and has good chemical stability.
5. Good mechanical performance. Because of its strong structure, it can withstand twisting, squeezing, bending, pulling, friction and general heavy handling.
6. Because the heating method of the heating cable belongs to a series of resistance electric heating elements, the heating is uniform and the temperature difference over the entire length is extremely small
7. The heating power is large, generally 30~250W/m. The heating cable will not be frozen due to the stop of steam supply like the steam heating pipeline. The power supply can be turned on when needed, without frequent maintenance.
8. Low temperature resistance, no brittle break during construction at low temperature, easy for winter construction and maintenance
9. It is resistant to solar radiation and nuclear radiation, and the working temperature is high. 250°C, 400°C, 600°C.
The heating and heat preservation technology of MI heating cable|MI heat trace cable is a new method for heating and heat preservation of metal pipes developed in the market in recent years. It is a new technology and new process for heating and heat preservation of heat transmission pipelines in large petrochemical enterprises.
