Pipe Rack System Complete Solution - HJ-1 Metal Pipe Joints for Industrial

Product Specification

Product Overview

A pipe rack system is only as reliable as its weakest connection point, and the HJ-1 Metal Pipe Joint is engineered to be that reliable foundation. Designed specifically for 23mm wall thickness pipe rack pipe, the HJ-1 uses a precision machined CRS cold rolled steel body with a black electrophoresis finish to deliver a connection that is structurally sound, corrosion-resistant, and -- critically -- reusable when system configurations need to change. The HJ-1 arrives as a complete kit: two H-1 joint bodies plus the M6x25 hardware required for full assembly, so there are no missing fastphens or compatibility issues at installation. The bolted connection mechanism uses the M6 hardware to create a clamp-style joint that captures the pipe from both sides -- a double-sided clamping configuration that distributes loading forces more evenly than single-clamp alternatives and reduces stress concentrations at the pipe wall.

Key Benefits

· Complete kit delivery -- HJ-1 ships with both H-1 joints and M6x25 hardware, eliminating the common problem of receiving structural hardware without the fasteners needed to complete assembly

· 23mm pipe wall compatibility as standard specification -- the HJ-1 is designed specifically for the 23mm pipe wall thickness that is the standard for industrial pipe rack applications, ensuring dimensional fit without custom shimming or modification

· Double-side clamping joint geometry -- the two H-1 joints in each HJ-1 create a symmetrical clamping configuration that distributes mechanical loads more evenly and reduces stress concentrations at the pipe wall interface

· CRS cold rolled steel with electrophoresis -- the same material and coating specification used in demanding industrial environments, providing the combination of structural strength and corrosion resistance that pipe rack systems require

· Reusable for system lifecycle management -- unlike welded systems that are permanently assembled, the HJ-1 can be disassembled and the joints and pipes redeployed in new configurations, extending the useful life of the material investment across multiple facility layouts

Applications

Complete pipe rack system construction for warehouses and distribution centers, production line structural framing, industrial storage racking, mezzanine and platform support structures, conveyor support frames, and machinery guarding frames. The reusable nature of the HJ-1 system makes it the preferred choice for third-party logistics operators and contract manufacturers who may need to recover and redeploy their racking infrastructure at the end of a contract term, and for any facility that is actively managing its layout as part of a continuous improvement or operational excellence program.

Why It Works

The engineering of a bolted pipe rack joint involves a subtle but important trade-off between clamping force and pipe wall integrity. The HJ-1 manages this trade-off through its two-piece H-1 clamping design. When the M6 bolt is tightened, both H-1 joints draw together against the pipe from opposite sides, creating what engineers call a 'double shear' loading condition at the fastening point. Double shear is significant because it roughly doubles the load-carrying capacity of the connection compared to a single-sided clamp -- the force is distributed across two cross-sectional areas of the fastener rather than one. The CRS cold rolled steel substrate is important here because cold rolling produces a finer, more consistent grain structure than hot rolling, which means the threads on the M6 hardware engage cleanly in the joint body without cross-threading and maintain their preload under vibration and dynamic loading. The electrophoresis coating contributes to this by maintaining a consistent coefficient of friction at the joint interfaces -- the coating does not compress or cold-flow under clamping load the way polymer-based coatings can, so the joint maintains its tightening specification over repeated assembly and disassembly cycles.
