USED 1987 SERTOM PP HD 250

Sertom PP HD 250 Heavy-Duty Hydraulic Section Profile Angle Bending Roll (1987)

• Angle Iron (Leg In / Out): Up to approx. 8" x 8" x 3/4" (200 x 200 x 20 mm)
• Flat Bar (Easy Way / Hard Way): Up to 10" x 2" (250 x 50 mm) or equivalent section modulus
• I-Beam / H-Beam (Hard Way): Capable of bending structural beams (such as HEB/HEA types) up to approx. 240–300 mm profiles with specific structural traction attachments.
• Pipe / Tube Bending: Up to approx. 8"–10" Schedule 40/80 pipe with custom-radius modular tooling.

Component Manufacturing Standard Specs

Sertom builds custom non-mass-produced units engineered with high-tier components to simplify universal field replacement:
• Hydraulic Valves: Exclusively built with Bosch-Rexroth valves.
• Bearings: Heavy-duty double conical roller bearings from SKF or FAG.
• Seal Configuration: Calibrated Busak-Shamban / Trelleborg high-pressure gaskets rated for up to 700 bar.
• Piping Layout: Solid rigid steel hydraulic lines throughout (no pressure-expanding rubber hoses) to eliminate precision loss during high-tonnage load operations.

Sertom PP HD 250 Angle Bending Roll

The Sertom PP HD 250 (often classified under Sertom PB’s PP-VG series) is a heavy-duty, hydraulic variable-geometry profile and angle bending roll designed to handle complex structural steel sections, heavy pipe, and large profiles.
The defining architecture of the "PP" variable-geometry series is its three-roller motorized setup where the upper roll moves vertically (translates) and the lower rolls adjust horizontally and independently. This variable pitch configuration functions as either a pyramidal or asymmetrical machine, maximizing pre-bending capabilities while minimizing the unbent straight sections at the profile ends.

Core Mechanical Design & Features

• Variable Geometry Setup: By increasing or decreasing the center distance between the lower rolls, the machine can adapt perfectly to roll thick-walled profiles or execute tight-radius bends on thinner materials.
• All-Roll Drive: All three rolls are fully motorized, which prevents material slippage when processing heavy beams, channel sections, or smooth pipes.
• Independent Pre-Bending: The independent hydraulic horizontal adjustment of the lower rollers allows for high-precision pre-bending on both the leading and trailing edges of the profile.
• Anti-Twist Mechanics: Equipped with multi-directional (axial, radial, and angular) hydraulic guide rolls. These structural lateral guide systems are essential for counter-acting the natural twisting effect that occurs when bending asymmetric profiles like angle iron or leg-in channels.

Common Industrial Applications

The PP HD 250 series is heavily utilized across heavy industrial sectors due to its capacity to roll structural shapes:
• Heavy Structural Fabrication: Rolling structural steel sections like H-beams (HEA/HEB), standard I-beams, and large channel sections.
• Shipbuilding & Energy: Curving massive framework panels, heavy-duty support rings, wind tower components, and thick-walled pipes.
• Industrial Modular tooling: Frequently equipped with specialized accessory components like specific pipe rollers, structural traction systems, and compression pressure rollers to handle specialized, non-standard geometry.
If you are evaluating this machine for a specific project or facility acquisition, could you tell me:
• The exact profile types and dimensions you need to roll (e.g., specific H-beam sizes, angle iron dimensions)?
• The minimum bending radius your materials require?
• Whether you are sourcing a new unit or looking for used equipment specs/pricing?
Knowing these details will help me provide tailored capacity charts or structural comparisons.
