Product Description

Pipe Welding Joint Electric Heating Device​ of mineral insulated heating cable is suitable for manual welding, semi-automatic and automatic welding operation for steel pipeline. For the repair port and other separate operations, it is also possible to use the welding joint electric heating to ensure the stability of heating temperature.


1. Product structure and completeness of Pipe Welding Joint Electric Heating Device

1)Product structure

Using stainless steel material as the main structure frame for the welding joint electric heating belt, MI heating cable with stainless steel sheath is used as heating element, and enhanced aluminum silicate fiber rope of high temperature resistance is used as internal insulation material. The outer protection is a flexible stainless-steel shell.


The energy storage spring of welding joint electric heating belt can absorb stably the thermal elongation generated during the working process.


A mounting clasp is applied can be locked with a quick installation and safe self-locking power outlet.Installation thread of temperature sensor is to facilitate automatic temperature control.Rubber-sheathed cable withstands cold temperature of -20℃.

 

2)Complete set

According to the actual use of the site and the requirements of welding process, a welding joint using two welding joint electric heating belts and an insulation quilt and a set of circuit protection control box (optional with automatic temperature control) are designed accordingly, combined into a set of welding joint heating device.


2. Technical features and model name of Pipe Welding Joint Electric Heating Device

1). Technical characteristics

a) easy to operate and use

The welding joint of the electric heating belt is compact, strong, with high surface heating intensity, high service temperature and suitable for field construction conditions.

A belt can be installed after one installation action, and it can be continuously used in the welding process simply and conveniently.


b) Welding quality is secured by a fast temperature increase.

The pipe welding joint can be heated up in 20 minutes to 80 ℃ or higher, (reference diameter Ф1016 with a wall thickness of 14.6 mm). Normal mechanical interface operation will not be affected by preheating operation.

The welding joint temperature reaches the standard, so that the construction and supervision unit can rest assured about the welding quality.

Heating does not affect pipe welding while welding and weld bead repair operations do not affect heating. That no process crosses, improves work efficiency. (5 more welding beads can be welded averagely in a day)


c) High temperature and corrosion resistance

There is a flexible stainless steel shell on the welding joint electric heating device, which can resist the splash or burning of arc and welding slag during processing.


d)Energy and cost saving

Welding joint heating device is pure resistive load, installed to a field welding generator coordinated with inductive load, which can improve the power factor of the generator, increase output, make full use of the abundant backup power of the field welding generator, so there is no need to increase energy and costs.


e) Safe and secure

Complete set of product possesses high electrical insulation strength to ensure the safety of users with special grounding wire and leakage protection switch.


f) convenient maintenance

Under normal and correct conditions, there is basically no maintenance workload.

When not in use, it is like other mobile appliances, need to be placed in a dry place to avoid accidental impact.

Once the insulation layer is affected by moisture absorption, the device can be electrified for self - drying before normal use again.


2). Model naming

The product name is composed of "product name" and the applicable "pipe outer diameter", with "-" interval in the middle.
