Big Ton Spring Supports

Founded in 2012, Yangzhou Tianshun Pipeline Technology Co., Ltd. has extensive R&D and manufacturing expertise in heavy-duty pipeline support solutions. Our Big Ton Spring Supports are a customized product line developed for ultra-high load conditions, breaking the load limit of conventional spring hangers. Designed exclusively for extreme scenarios with single lifting points exceeding 100 tons, they have been successfully deployed in multiple national-level key energy projects.

What Are Heavy-Duty Working Conditions? Industry Pain Points

In large-scale energy and petrochemical projects, pipelines with extreme loads include:

Ultra-large diameter thick-walled pipelines: DN1200+, wall thickness ≥50mm, weight per meter over 5 tons

Large equipment connection pipelines: Inlet/outlet of reactors, heating furnaces, steam turbines, single lifting point load over 100 tons

Long-span pipe rack mains: Span ≥30 meters, with massive concentrated loads

Special alloy pipelines: Duplex steel, nickel-based alloy pipelines, far heavier than carbon steel due to high material density

Limitations of conventional products:

Maximum load of standard spring hangers typically does not exceed 40 tons

Ordinary structures deform and lose stability above 80 tons

Multi-group parallel connection fails to ensure synchronization, causing eccentric loading

Very few domestic manufacturers can reliably produce 100-ton+ supports

Big Ton Spring Supports are purpose-built to solve this industry-wide challenge.
