Factors influencing the quality of duct-type explosion-proof electric heater
Mar 08, 2016

Explosion-proof electric heater system is mostly transported by pipeline, piping and connections between the pipes, piping and other components, in addition to bolted connection is welded. Welded to the flange on the pipe, then bolted to connect two pipes. Because is sweet and hot oil in the pipeline, so relatively high temperature and pressure, weld will have a direct impact on the quality of the system as a whole.

Today's technology has had a great deal of development, can weld mechanical properties equal to or even higher than that being connected, no internal and external defects of weld. Welded joints welding position in space, the strength of joints not only under the influence of weld quality, geometry, forces, dimension and working conditions affect both.
