The series features three cutting-edge sub-models—W313B, W313B5, and W313E—each optimized for specific industrial applications. Key innovations include an integrated wedge design that ensures friction-free, parallel movement, preventing flange damage and minimizing the risk of tool failure. The unique interlocking wedge mechanism eliminates initial bending and joint misalignment, while requiring an incredibly small access gap of just 4–6mm, making it ideal for tight-space operations in pipelines, valves, and heavy machinery.
For versatility, the W313 Series offers both mechanical and hydraulic variants. Hydraulic models deliver robust spreading force (up to 28 tons), combined with lightweight designs (as low as 6kg) and rotating handles for easy horizontal/vertical operation. For heavy-duty needs, dual-acting hydraulic models ensure rapid flange separation even in the most demanding environments. All models feature forged key components for durability, quick-disassemble cutter heads for easy maintenance, and a range of stroke capabilities (up to 103.5mm) to suit diverse project scales.
“Our W313 Series transforms flange maintenance by prioritizing safety, speed, and user convenience, whether for routine inspections, shutdowns, or critical repairs, these spreaders reduce downtime and labor costs while enhancing operational safety.”
Backed by Yantai Winner’s commitment to quality, the W313 Series is now available for global orders. Customers can pair spreaders with optional FSH-14 bolting tool-pump sets for a complete solution.
