Equipment

Shihua pipe fittings-700KW electric furnace

Shihua pipe fittings-700KW electric furnace is a heating furnace that converts electric energy in the furnace into heat to heat the workpiece. Compared with fuel furnace, electric furnace has the advantages of easy control of atmosphere in the furnace; Fast heating of materials; High heating temperature; Easy temperature control, etc.

Shihua pipe fittings -1220 intermediate frequency induction pushing unit

Features of medium frequency pipe bender of Shihua pipe fitting -1220 medium frequency induction pushing unit: 1) This process can avoid the phenomenon of uneven wall thickness of pipe bending caused by tension and thinning of convex edge of pipe wall and compression and thickening of concave edge of pipe wall during traditional pipe bending process. 2) Using this process, a small radius (R≈ D), thin-walled (t/D≈ 0.015)180 elbow with uniform wall thickness can be deduced, which cannot be achieved by other bending processes. 3) If the design of various process parameters is reasonable, the process can ensure that the thickness of the tube wall in each part of the bending process is always unchanged, that is, always equal to the thickness of the straight tube blank tube wall before deformation. 4)

Shihua Pipe Fittings -4000 Tons Cold Pusher

Shihua Pipe Fittings -4000 Tons Cold Pushing Machine This equipment is mainly used for cold pushing forming of carbon steel and stainless steel elbows. There are two pushing methods: steel ball pushing and mandrel forming pushing. The mandrel forming pushing is equipped with semi-automatic mechanical demoulding device. Forming principle: the tube blank is pushed into the forming cavity with the inner core set by the hydraulic ejector rod from the guide section in the tunnel cavity locked by the external force, bent and formed, and demoulded by the stripping device, and the whole process can be operated intelligently by PLC. Shihua has DN100, DN300, DN600 three sets of stainless steel elbow cold push unit.
