Stainless steel seamless elbows are connecting fittings used to change the flow direction in pipeline systems, accounting for about 80% of the fittings. The industrial equipment specialized in producing them is its processing equipment. This type of equipment uses metal plastic deformation technology to process stainless steel pipe blanks into various angles of elbow products.
There are four common types of equipment for stainless steel seamless elbows:
1. Cold forming equipment: extruded through molds at room temperature, suitable for thin-walled elbows below DN50.
2. Hot forming equipment: Heat to the recrystallization temperature (approximately 1050-1150 ℃ for austenitic stainless steel) before forming.
3. Push molding equipment: Metal flows along the core mold under axial thrust for molding.
4. Spinning forming equipment: Wall thickness uniformity is achieved through circumferential rolling of the spinning wheel.
The typical equipment models are as follows:
5000T Four Column Press: Large Pushing Equipment
500T four column press: medium-sized processing equipment
1000T gantry press: high-precision forming equipment
1620mm chain bending machine: large bending pipe processing
820mm Hydraulic Medium Frequency Pipe Bending Machine: Small and Medium Sized Processing
