Background technology
In riser joints welding technique, some special connectors, since the difference of purposes causes connector to be made
Material used in material and ordinary couplings is different, the connector of some special substances when with pipe welding,
It, otherwise can be due to according to the treatment measures that technological requirement needs to carry out weld preheating to tube body and connector and postheating is kept the temperature
Heating temperature is not enough or heating is irregular, soaking time is short causes connector welding bead to be susceptible to the weld defects such as Interlaminar Crack.
During previous weld job, used pre-heating mean is manually right using two individual heating grilled guns
The steel pipe and connector of rotation are heated.Since manually-operated factor easily causes the temperature of local welding bead in heating process
The numerical value of technological requirement is not achieved, also will appear the phenomenon that efficiency of heating surface is low, and to the consumption of burning gases in arctic weather
It is also that comparable tool is big.

There is stent；The stent includes upper bracket, lower carriage, fixing bolt and pedestal, and the lower carriage bottom is welded on pedestal
On, lower carriage top is equipped with fixing bolt, and the fixing bolt is fixed on upper bracket, and heating is equipped at the top of upper bracket
Rifle；The heating gun includes pipette tips, gas-distributing pipe line, gas outlet and hand-operated valve, and the gas outlet side is equipped with hand-operated valve,
Described gas outlet one end is connect by gas-distributing pipe line with pipette tips, and the gas outlet other end is welded at the top of gas-separating valve, point
Air valve bottom is welded with two gas outlets, and gas-separating valve side is welded with source gas line；The source gas line includes air inlet and master
Gas pipeline, the air inlet side are equipped with hand-operated valve, and described air inlet one end is welded on gas-separating valve side, and air inlet is another
One end is connect by main gas pipeline with air source.
The heating gun is mutually in 90 °.
The heating gun is three or four, and gas outlet matches with heating gun.
The heating gun is in the equidistant configuration of pipe end weld.
The upper bracket can up and down adjustment heating gun height.

The stent can be moved left and right along track.
The wheel is four.
The beneficial effects of the utility model are：1st, homogeneous heating；Due to being fixed heating gun, three the equidistant configuration of rifle
The temperature of welding bead can be made uniformly to increase, avoid the phenomenon that uneven in temperature.
2nd, heating time is short, and temperature rise is fast.Heating gun increases three by original two, and in view of Large Diameter Pipeline
Heating problems reserved installation top the 4th in advance heating gun and its interface of attachment, increase this device plurality of specifications and appoint
Expanding space for business, avoids the waste of device.
3rd, good economy performance, fuel consumption are small.Distributed mode of heating as compared with the past, this device use the original of central gas supply
Reason, and heating speed is fast, is significantly improved for the utilization rate of fuel.
4th, using flexible, conveniently；As a result of the principle fixed occupation mode as compared with the past of cart type, increase
The flexibility that place uses.
