Do I have to seal the end of the heating tape?

　　As an advanced pipeline insulation technology, electric heating tape is widely used in chemical, electric power, petroleum and other industries. It can provide safe and reliable temperature control and anti-freezing and condensation function for various industrial applications. However, in the installation and use of electric trace heat tape, the problem of tail end sealing has been a concern. So, the electric accompanied by the tropical end must be sealed? This article will explore this issue from a variety of perspectives.

　　First, the importance of electric accompanied by tropical end sealing

　　1. Prevent water vapour intrusion

　　The electric accompanies the tropical in the operation process will produce the heat, if the end is not sealed, the water vapour may invade the electric accompanies the tropical inside. The intrusion of water vapour will lead to the decline of electrical performance of electric trace heating tape, and may even cause short circuit and fire. Therefore, the sealing of the end can effectively prevent the intrusion of water vapour, and guarantee the safe operation of the electric heating tape.

　　2. Improve insulation performance

　　The insulating property of electric traceable heat belt is the important guarantee for its normal operation. If the tail end is not sealed, moisture and dust and other impurities may enter into the electric accompanied by the tropical interior, resulting in insulation performance decline. Tail-end sealing can effectively improve the insulation performance of electric traceable heat tape and prolong its service life.

　　3. Prevent foreign matter from entering

　　In some special industrial environments, dust, impurities and other foreign matter may have an effect on the performance of electric traceable heat. If the tail end is not sealed, these foreign matter may enter into the electric accompanied by the internal heat, resulting in electric accompanied by the performance of the tropical decline. Tail end sealing can effectively prevent the foreign matter from entering, safeguard the normal operation of electric accompanied by tropical.

　　Second, the electric accompanies the tropical tail end sealing method

　　1. Use the tail end junction box for sealing

　　Tail end junction box is a kind of commonly used electric accompanies the tropical tail end sealing method. By connecting the tail end of the electric accompanying heat tape to the tail end junction box, it can effectively prevent the intrusion of water vapour and foreign matter. In addition, the tail end junction box also has waterproof, anticorrosive, high temperature resistance and other characteristics, can be in the humid, corrosive environment in the long-term stable operation.

　　2. Use of heat shrink tubing for sealing

　　Heat shrinkable sleeve is a kind of commonly used sealing method of electric accompanied by the end of the heat tape. By wrapping the end of the electric accompanying tropical tape in the heat shrinkable sleeve, can effectively prevent the intrusion of water vapour and foreign matter. In addition, the heat shrinkable sleeve also has the characteristics of waterproof, anticorrosion, high temperature resistance and so on, and it can run stably for a long period of time in the humid and corrosive environment.

　　3. Sealing with insulating tape

　　The insulating tape is a kind of commonly used electric accompanies the tropical tail end sealing method. By wrapping the end of the electric accompanying tropical tape in the insulating tape, can effectively prevent the intrusion of water vapour and foreign matter. In addition, the insulating tape also has the waterproof, the anticorrosion, the high temperature resistance and so on the characteristic, can in the humidity, the corrosion environment long term stable operation.

　　Third, electric accompanied by the sealing of the end of the tropical sealing precautions

　　1. keep dry

　　In the process of electric accompanied by the tropical tail end sealing, should keep the tail end dry. If the tail end is damp, it may lead to the electric performance of electric trace heating tape to decline, and may even cause short circuit and fire. Therefore, when sealing the tail end, make sure the tail end is dry and avoid the intrusion of water vapour.

　　2. Avoid short circuit

　　In the process of sealing the tail end of electric heating tape, the connection or contact of two wires should be avoided. If two wires are connected or contacted, it may lead to short circuit and fire. Therefore, when sealing the tail end, make sure that the two wires are separated to avoid the occurrence of short circuit.

　　3. Prevent grounding

　　In the process of sealing the tail end of the electric heating cable, the access to the shielding layer should be avoided. If the shielding is accessed to the tail-end junction box, it may cause the circuit to be grounded. In the case of poor contact of the grounding protection, electrical sparks may be generated, causing a fire. Therefore, the separation of the shielding layer should be ensured when the tail end is sealed to avoid the occurrence of grounding.

　　In summary, the tail end of the electric heating tape must be sealed. Tail end sealing not only can effectively prevent the intrusion of water vapour and foreign matter, improve the insulating property of electric accompanied by tropical, but also can guarantee the safe operation of electric accompanied by tropical and prolong its service life. In the process of sealing the tail end of the electric accompanying tropical tape, should keep the tail end dry, avoid the occurrence of short circuit and grounding. Only in this way, can give full play to the role of electric accompanied by tropical, for a variety of industrial applications to provide safe, reliable temperature control and anti-freezing and condensation function.
