20-Ton Hydraulic Pipe Upender for Pressure Vessel Manufacturer in Saudi Arabia: Safe 90° Tilting Solution

A major industrial pressure vessel and pipeline manufacturer based in Dammam, Saudi Arabia, required a reliable and controlled method to rotate massive cylindrical workpieces. Previously, the facility relied on overhead cranes and manual rigging to flip 3-meter-long (9.8 ft) pressure vessels with diameters ranging from 2,500 mm to 7,000 mm (8.2 to 23.0 ft) by 90 degrees for welding and structural inspection. To streamline production, minimize labor hours, and prevent potential damage to the vessel walls, the plant integrated our custom 20-ton hydraulic upender with a specialized physical support structure.

Client Profile: Heavy Industrial Pressure Vessel & Pipeline Fabricator
Project Location: Dammam, Saudi Arabia
Core Equipment: Custom 20-Ton Hydraulic Upender with Integrated V-Groove (Model: HU-20T-V)
Project Objective: To achieve safe, controlled 90-degree tilting of large-diameter cylindrical pipes without depending on active overhead crane suspension during rotation.

Challenge & Solution

Challenge

Handling massive cylindrical steel structures during the fabrication process presented several logistical and safety obstacles for the facility:

High-Risk Crane Sling Flipping: Tilting 20-ton cylindrical loads using overhead crane slings was unstable, as the straps were prone to shifting along the smooth curved metal, presenting extreme risks of sudden slippage.
Extreme Pipe Roll-Off Risk: Standard flat-bed upenders cannot stabilize round workpieces. With diameters reaching up to 7,000 mm (23.0 ft), the cylindrical vessels would roll laterally during the 90-degree transition, resulting in severe weight imbalance.
Workpiece Deformation & Bottlenecks: Manual rigging and balancing for each crane-assisted flip took over 45 minutes. Additionally, the concentrated pressure from heavy lifting slings frequently caused surface dents or structural deformation to the expensive vessel walls.

Solution

To resolve these operational challenges, our engineering team delivered a heavy-duty, electro-hydraulic 90-degree upender specifically configured for cylindrical industrial loads.

Integrated V-Groove Platform Geometry: Designed a dual-section platform (

 $3 m \times 4.8 m$ and  $4.8 m \times 7 m$ ) equipped with a built-in heavy-duty V-groove to securely cradle and self-center round pipes ranging from  $Φ2, 500 mm$  to  $Φ7, 000 mm$ .

Controlled Multi-Cylinder Hydraulic Drive: Powered by an 11kW hydraulic pump station and dual high-capacity $Φ150 - 105$ cylinders, the system completes the 90-degree tilt smoothly within 10 minutes, eliminating rapid or uncontrolled center-of-gravity shifts.
Ultra-Rigid Steel Framework (J30020010): Constructed using heavy-duty J30020010 structural channel steel and a 4mm plate surface, supported by L-shaped physical retention walls that completely eliminate the need for overhead crane intervention.
