Hot Expanding Machine for Expanding Pipe or Refreshing Used Pipe

Product Description

hot pipe expanding machine
Performance
The equipment is a specialized device for petroleum,chemical industry,electric power,oil and gas pipeline
and other fittings ;it was designed and manufactured by our company ;it synthesized many years of
improvement and technical requirements in fittings industry. It mainly chooses seamless and welded pipes
as raw material and makes use of hydraulic pushing-method equipment mating intermediate frequency
heating system to realize the production procedure of hot expanding pipe diameter. The products adapt
carbon and alloy steel pipes expanding from original small-diameter pipes to big-diameter pipes.the
equipment possesses logical design, reliable working,convenient operation,automatically feeding system
for relicving labor intensity;main unit _adapts hydraulic rotation easy to realize the rapid shifting between
stepless speed governing speed -reverse with working process,and can easily adjust thrust.it can run
stably with little noise,the circuit board of intermediate frequency power adapts advanced technology;
starting circuit with constant power digital sweep frequency can run smoothly and reliably with low failure rate.
