Abstract
The utility model discloses an intelligent temperature self-regulating heat tracing cable for an oil-gas pipeline, relates to the technical field of cable manufacture and particularly relates to the intelligent temperature self-regulating heat tracing cable for the oil-gas pipeline. The intelligent temperature self-regulating heat tracing cable comprises a sheath; a main heat tracing tape is wrapped by the sheath; the main heat tracing tape comprises heating leads, a temperature self-regulating layer, an insulation layer, a tin-coated copper wire shielding layer, a flame-retardant polyolefin inner sheath and a metal armor layer; the sheath is internally provided with an auxiliary heat tracing tape; and the auxiliary heat tracing tape comprises heating leads, a temperature self-regulating layer, an insulation layer, a tin-coated copper wire shielding layer, a flame-retardant polyolefin inner sheath and a metal armor layer. The auxiliary heat tracing tape is additionally arranged on the basis of a conventional main heat tracing tape so that the intelligent temperature self-regulating heat tracing cable for the oil-gas pipeline has the advantages of not only superior heating, temperature control, energy conservation, oil resistance, corrosion resistance, flame retardation and anti-interference properties, but also simple structure, convenient use and saved cost.
Description
Technical field
The utility model relates to the intelligent automatic temperature-controlled heat tracing cable of cables manufacturing technical field, particularly oil/gas pipe line.
Background technology
Automatic temperature-controlled heat tracing cable is the intelligent insulation companion hot product that U.S. RAYCHEM company succeeds in developing the eighties, and its application is more and more extensive.The core material PTC semiconductive plastics of temp auto-controlled electric tracing cable, its resistance value increases with the rising of temperature, but when temperature rises to certain numerical value (adjusting size as required), resistance increases severely suddenly, thus the heating of blocking-up current stops; When temperature during lower than threshold temperature, the resistance of the ptc material On current that automatically descends, continue heating.Thereby make system held in a stable temperature range.These characteristics make the automatic control hot line be suitable for insulation, companion's heat, temperature control, the heating of pipeline, equipment and container.In recent years, quickening along with China's modernization, demand for energy is increasing, and China has organized and implemented that " West-east Gas, " Xi Youdong send ", transnational On The Oil And Gas Transportation Project etc., temp control electric heating cable is widely used at oil/gas pipe line on a large scale.Often take special automatic temperature-controlled heat tracing cable for the longer pipeline of the hot length of companion in prior art.Carry out heat exchange to supplement its thermal loss by heating cable and ducted liquid, but existing Special self-thermal control heat tracing cable is because production technology is immature, accuracy of temperature control is low, and structure more complicated all, and cost is higher, and companion's thermal effect is also not so good.
The utility model content
The utility model purpose is for above problem, provides a kind of and there is excellent heating, temperature control, energy-conservation, oil resistant, the performance such as corrosion-resistant, fire-retardant, anti-interference, easy to use, and the intelligent automatic temperature-controlled heat tracing cable of cost-saving oil/gas pipe line.
The utility model comprises sheath, coats main heating tape in described sheath, and described main heating tape comprises heating-wire, temp auto-controlled layer, insulating barrier, tinned copper wire screen, fire retardant polyolefin sheath and metal armouring layer; Also be provided with secondary heating tape in sheath, described secondary heating tape comprises heating-wire, temp auto-controlled layer, insulating barrier, tinned copper wire screen, fire retardant polyolefin sheath and metal armouring layer.
Secondary heating tape described in the utility model is set in parallel in a side of main heating tape.
Main heating tape described in the utility model is flat structure, and described secondary heating tape is also flat structure.
The utility model is set up secondary heating tape on the basis of original main heating tape, not only has excellent heating, temperature control, energy-conservation, oil resistant, corrosion-resistant, fire-retardant, jamproof characteristic, and simple in structure, easy to use, cost-saving.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises sheath 1, in the present embodiment, is coated with main heating tape 2 and secondary heating tape 3 in sheath 1, and secondary heating tape 3 is set in parallel in a side of main heating tape 2, and sheath 1 is the modified flame-retardant polyolefin.
Main heating tape 2 comprises heating-wire 4 and temp auto-controlled layer 5 for flat structure and it, and heating-wire 4 is embedded in temp auto-controlled layer 5, in temp auto-controlled layer 5 outside, is coated with successively insulating barrier 6, tinned copper wire screen 7, fire retardant polyolefin sheath 8 and metal armouring layer 9.
The corresponding main heating tape 2 temp auto-controlled layer of secondary heating tape 3 temp auto-controlled layers are set to flat structure, in the present embodiment, secondary heating tape 3 comprises heating-wire 4 and temp auto-controlled layer 5, heating-wire 4 is embedded in temp auto-controlled layer 5, at temp auto-controlled layer 5 outside coated insulation layer 6 successively, tinned copper wire screen 7, fire retardant polyolefin sheath 8 and metal armouring layer 9.
