HJ-7A Metal Pipe Joint Clamp (27.6–28 mm)

HJ-7A Pipe Joint – Description The HJ-7A is a metal pipe joint clamp used in modular pipe-and-joint systems to connect two parallel horizontal pipes. It is a variation of the standard HJ-7 with a slightly modified profile for improved stability and easier assembly. It is typically used in lean manufacturing structures such as workstations, racks, flow racks, and material-handling frames. Technical Specification (Typical for HJ-7A) ParameterSpecification Compatible pipe size Ø 27.6–28 mm (standard coated pipes) Material Cold Rolled Steel (CRS) Finish Black powder coating (most common), zinc plating optional Bolt size M6 × 25 mm or depending on manufacturer Structure Two-piece parallel clamp with central fastening screw Function Connects two horizontal pipes in parallel alignment Weight ~90–120 g (varies by brand) Features Provides strong parallel support between two pipes Non-welded assembly for flexible structure building Compatible with most lean pipe systems (Kaizen tubing) Quick installation using a single screw Durable powder-coated surface for corrosion resistance Industrial Applications Conveyor frames FIFO / flow rack reinforcements Material handling trolleys Modular shelves Workstation crossbars Structural bracing for pipe frames These clamps are widely used in: Lean manufacturing workstations Modular pipe & joint systems Flow racks / FIFO racks Trolleys, carts, and dollies Shelving and storage structures Assembly lines Material handling equipment They allow quick assembly, adjustment, and disassembly of structures without welding.
