23mm Adjustable Metal Pipe Joints HJ-1 - Flexible Pipe Rack System Component

Product Specification

Product Overview

Pipe rack systems built around the HJ-1 adjustable metal joint deliver a level of flexibility that rigid welded structures simply cannot match. The HJ-1 is a T-type structural connector designed for 23mm wall thickness pipes, manufactured from CRS cold rolled steel and finished with a black electrophoresis coating that provides both the visual presentation and the corrosion protection required for industrial environments. The defining engineering characteristic of the HJ-1 is its bolted fastening mechanism: each unit consists of two H-1 joints connected by an M6x25 bolt and nut, and the assembly requires only a single M6 inner hexagon key -- no torque wrench, no welding station, no specialized tooling of any kind. This simplicity has a direct practical implication: production engineers and floor supervisors can reconfigure entire racking systems in hours rather than the days or weeks that welded structures require for modification.

Key Benefits

· T-type adjustable joint geometry -- the T junction configuration allows pipes to branch in three directions from a single joint, creating complex structural configurations from a limited set of standardized components

· 23mm pipe wall thickness design -- the 23mm wall thickness of the pipes it connects is the most common industrial pipe rack specification, making this a drop-in solution for standard pipe rack applications

· Single M6 hex key assembly -- one tool, one person, no special training required for installation or reconfiguration, which dramatically reduces labor costs associated with pipe rack modifications

· Fully reusable and reconfigured -- the bolted joint can be disassembled and the pipes and joints reused in a new configuration, making the initial investment in the system recoverable rather than sunk

· Black electrophoresis finish -- the coating provides both aesthetic consistency for commercial visible installations and functional corrosion protection for factory floor environments

Applications

Flexible manufacturing workstation layouts, lean production cell configurations, reconfigurable storage and racking systems, modular exhibition and trade show booth structures, electronic assembly station frames, logistics sortation equipment, and workshop utility management systems where pipe and joint structures support tooling, monitors, and material handling equipment. The reconfiguration speed makes it especially relevant for high-mix, low-volume manufacturing environments where production cell layouts change every few weeks as product families shift.

Why It Works

The fundamental engineering advantage of a bolted pipe joint system over a welded one is thermodynamic: welding introduces heat to the steel, which changes the microstructure of the heat-affected zone and can introduce residual stresses that weaken the material over time. The HJ-1 avoids this entirely by using mechanical fastening rather than thermal joining. The electrophoresis coating on the joint also benefits from this approach: because the joint is never heated after coating, the coating integrity is never compromised by thermal cycling. The two H-1 joints that make up each HJ-1 create a structural sandwich at the pipe interface, distributing the mechanical loads across a wider contact area than a single clamp would provide. This reduces the stress at any single point and extends the fatigue life of the joint under dynamic loading conditions -- important in applications like production lines where vibration and periodic loading are constant.

Combination:

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