Thermal expansion pipe

Intermediate frequency expanding machine for steel pipe thermal expanding special equipment, mainly for domestic large diameter steel pipe production cannot meet the demand of market and all kinds of steel pipe specification is not complete, meet the needs of small batch more varieties of steel pipe production, can satisfy the different material steel pipe hole enlargement and various non-standard steel tube expanding needs, is currently the main production process of large diameter steel pipe.

Thermal tube expanding machine refers to the production of low density but strong contraction of the pipe fitting equipment, (seamless steel tube) can be referred to as thermal tube expanding.A process in which the diameter of a pipe is enlarged by cross - rolling or drawing.In a short period of time to thicken the steel pipe, can produce non-standard, special type of seamless pipe, and low cost, high production efficiency, is the development trend of international rolled pipe field.
