Engineering Overview & Structural Features

The HFS-I Series Stepped Hydraulic Flange Spreaders deliver highly reliable, non-destructive flange separation for high-pressure piping networks, offshore facilities, and heavy industrial plant maintenance. Utilizing a specialized stepped interlocking jaw architecture that requires only a 6.0 mm entry clearance, the tool delivers 140 to 240 kN (14 to 24 Metric Tons) of controlled spreading force per tool with a maximum parallel opening of up to 103.5 mm when configured with stepped accessory blocks. Available in manual mechanical ratchet, 700 Bar external hydraulic, and fully self-contained integral hand pump configurations, the HFS-I Series eliminates traditional hammering hazards and joint damage during gasket replacement and routine turnaround inspections.

CORE ENGINEERING ARCHITECTURE & TECHNICAL SPECIFICATIONS
01

360° Revolving & Detachable Handle

Engineered with an ergonomic revolving grip that rotates 360 degrees to facilitate smooth horizontal or vertical tool positioning in congested pipe racks, featuring a quick-detach mechanism for unhindered operation in severe spatial clearance restrictions.

02

Zero Pinch-Point & Safety Lanyard

Constructed with built-in operator pinch-point elimination and includes a standard 1.0 m heavy-duty safety lanyard for secure structural tethering during high-elevation or offshore flange maintenance.

03

Stepped Jaws & Extended Step Depth

Features an ultra-slim 6.0 mm entry tip clearance, increased step-depth geometry on upper wedge tiers, and narrow wear-resistant teeth that enable secure, slip-free progressive separation from 6.0 mm to 103.5 mm under full 240 kN rated loading.

04

Drop-Forged Build & Rapid Assembly

All primary structural spreading components are forged from high-tensile alloy steel for maximum fatigue resistance, supported by modular tooling architecture that ensures rapid field disassembly, seal inspection, and immediate reassembly.
