Adjustable Metal Pipe Joints HJ-1 - 23mm Black Electrophoresis for Pipe Rack

Product Specification

Product Overview

The HJ-1 Adjustable Metal Pipe Joint is a precision-engineered connection component for pipe rack systems, manufactured from CRS cold rolled steel with a black electrophoresis surface treatment. The 23mm wall thickness provides the structural rigidity needed for demanding industrial storage, logistics, and production line applications. What distinguishes this joint from basic hardware store alternatives is the electrophoresis finish -- a process that bonds pigment to the steel surface at the molecular level, creating a coating that is both more wear-resistant and more corrosion-resistant than conventional paint or powder coating. Each HJ-1 unit ships as a complete assembly kit containing two H-1 joints plus the M6x25 bolt and nut set required for installation. The bolting mechanism means no welding, no special tools, and no dedicated assembly station -- one M6 inner hexagon key is all it takes to connect or disconnect the joint in seconds.

Key Benefits

· CRS cold rolled steel construction -- the material choice gives the joint the tensile strength and rigidity needed for heavy-duty pipe rack applications without the brittleness of cast iron

· Black electrophoresis surface treatment -- electrophoretically applied coating bonds at the molecular level for superior wear resistance and corrosion protection compared to conventional painted or powder-coated joints

· 23mm wall thickness -- matches standard industrial pipe rack pipe dimensions for a flush, structurally sound connection that does not compromise load-bearing capacity

· Fully reusable design -- both the joint and the pipes it connects can be disassembled and reconfigured as production layouts change, making this a long-term investment rather than a permanent installation

· One M6 hex key installation -- the single-tool assembly requirement means any maintenance technician or floor operator can reconfigure the system without waiting for specialized tooling

Applications

Industrial storage shelving systems, logistics and warehouse racking, production line workstation frames, assembly jigs and fixtures, commercial display and exhibition booth structural frames, electronic manufacturing equipment frames, and workshop utility rack configurations. The reusable nature of the system makes it particularly well-suited to lean manufacturing environments where production layouts change frequently in response to product mix or process improvement initiatives.

Why It Works

The combination of CRS cold rolled steel and electrophoresis treatment is what makes this joint perform in industrial environments where lesser hardware fails. Cold rolled steel has a finer grain structure than hot rolled steel, which translates directly into better surface finish and more consistent mechanical properties -- important in a load-bearing structural component. The electrophoresis process used here is the same electro-deposition coating technology used in automotive underbody protection: the coating wraps around complex geometries uniformly, reaching edges and crevices that spray-on coatings miss. The result is a joint that resists the abrasion, moisture, and chemical exposure typical of factory floor environments. The two-piece H-1 joint assembly within each HJ-1 unit creates a four-point contact structure when mated with a standard pipe, distributing loads evenly and reducing stress concentrations at the connection point.

Combination:

one HJ-1 is combine with 2 pcs of H-1 ,and one set of M56*25 nut and screw
