Line Fittings Tell You How To Use Gas Welding To Heat And Bend

Pre-insulated Sleeve tells you how to use gas welding to heat and bend:

When the pipe wall is thick or the pipe diameter is large, it can be heated by gas welding and then bent (filling the pipe with sand), but attention should be paid to the temperature to avoid insufficient heating and difficulty in bending, or excessive heating and uneven heating causing bending. In addition, for pre-buried pipes, gas welding can be used to heat and correct the position and twist and bend.
