Description

A kind of metal armouring heating tape

Technical field

The invention belongs to electric heating clothing arts, more particularly, to a kind of metal armouring heating tape.

Background technology

Under low temperature bad border, the problems such as difficulty in starting, pumped (conveying) medium freeze usually occurs in the part such as pipeline, so as to influence The normal work of equipment.Therefore, electric tracing part is needed to use in pipeline.Electric tracing is converted electrical energy into using electric tracing equipment For heat energy, by direct or indirect heat exchange, the heat lost by heat tracing equipment by insulation material is supplemented, and using temperature Degree control, reach the purpose of the temperature of medium in tracking and control heat tracing equipment.Electric-heating belt is due to preventing from overheating, use The advantage such as easy maintenance and saving electric energy, is suitable for pipeline, equipment and container temperature control, insulation, heating, particularly wherein there is thing When the easy decomposition of material, rotten, crystallization, cohesion are freezed, oil, chemical industry, building and agricultural byproducts production are widely used at present Etc. multiple industries.

Adhesive force in electric-heating belt in the market between layers is poor, and overall stranding after a period of time using tying Structure stability, resistance to elevated temperatures and anti-corrosive properties decline, and cause the situation for easily occurring heating power decline in use.

The content of the invention

In view of this, the present invention is directed to propose a kind of metal armouring heating tape, to solve the above problems.

To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：

A kind of metal armouring heating tape, including three groups of cored wires and be arranged at from the inside to the outside successively outside cored wire second insulation Layer, the second overcoat, screen layer and armor, every group of cored wire are arranged at outside conductor by wire and successively from the inside to the outside One insulating barrier and the first overcoat composition, the conductor includes tensile core and some wires, the tensile core are arranged on conductor Center at, some wire strandings around tensile core, between the wire and the first insulating barrier filled with conduction Paint, the first overcoat in every group of cored wire is overall structure and is integrally formed.

Further, some buffer springs are provided between first overcoat and the second insulating barrier.

Further, the material of first insulating barrier and the second insulating barrier is high density polyethylene (HDPE), low density polyethylene (LDPE) Or medium density polyethylene.

Further, first overcoat, the second overcoat are fluoro-containing plastic layer.

Further, the screen layer is tin-coated copper monofilament braiding layer or nickel-clad copper monofilament braiding layer.

Further, the armor is galvanized steel strip braiding layer.

Further, the material of the tensile core is carbon fiber.

Further, the outer surface of the armor is coated with fire prevention nano coating.

Relative to prior art, metal armouring heating tape of the present invention has the advantage that：

Metal armouring heating tape of the present invention is simple in construction, and heating is uniform, saves energy consumption, and inside sets buffer spring, prolonged Service life has been grown, and has possessed the performances such as good fire-retardant, anti-corrosion, can be widely applied for market.
