PIPE
PIPE TOP
In our piping engineering department, we manufacture and sell a variety of pipes ranging from HF bent pipe to polyethylene powder lined pipe, and also design and manufacture prefabricated pipes. all produced using our high-frequency induction heating technology.
SURFACE
TREATMENT
SURFACE TREATMENT TOP
Our high-frequency induction heating technologies are utilized for the heat processing of a wide array of product and to ensure the reliability of their quality
We not only manufacture large-scale parts, heavy machinery mass-produced items and highly precise products, but have also recently begun providing maintenance service for roll products.
MACHINERY
MACHINERY TOP
We design and manufacture various devices and machines through the use of induction heating technologies that DHF has developed over many years.
And for the application of induction heating, we also develop plant maintenance tools that help to reduce the work periods for repair, regular inspection and engineering work.
REBAR
REBAR TOP
In the T-head construction method for reinforcing steel bars, the end of a steel bar is hot-formed and processed into a T-shape using high-frequency induction heating. Offering a mechanical fixation method as an alternative to existing hook bending fixation, these special steel bars have been developed in collaboration with Shimizu Corporation.
We offer the service of processing steel bars from all manufacturers used by customers according to the intended usage.
Bi-MET
Bi-MET TOP
DHF Bi-met™ is a series of very unique bimetallic products manufactured through the
synergy between the applied technologies of self-fluxing alloys with excellent
resistance to wear and corrosion. and the high frequency induction heating (IH)
processing technologies that DHF has developed and refined over years.
“Bi-met” is our original word inspired by bi-metals.
PLANT ENGINEERING
