Specifications of pipe tray connecting pieces

Pipe tray connecting pieces include bolted splices, push-on splices, flat expansion bars, and intersection brackets, designed for secure, versatile, and corrosion-resistant connections.Types of Connecting Pieces1. Bolted Splices Bolted splices are used for end-to-end connections of tray sections and to attach mating surfaces at intersections. They provide a UL Classified bond when installed over bare metal surfaces and are available in black powder coat or electro-zinc finishes. These splices ensure a strong mechanical connection and are suitable for applications requiring electrical continuity . 2. Push-On Splices Push-on splices allow tool-free installation for end-to-end connections where electrical bonding is not required. They are also available in black powder coat and electro-zinc finishes and are ideal for quick assembly in environments where speed is prioritized over bonding . 3. Flat Expansion Splice Bars Flat expansion bars are used to join tray sections with small gaps or to create in-line width reductions. They are particularly useful when standard splices cannot fit due to spacing constraints. These bars provide flexibility in field-fabricated adjustments . 4. Intersection and Elbow BracketsRadius Intersection 90 Brackets protect cables at corners and can be formed from a single tray section or fabricated from two sections.Intersection Bend Fittings (e.g., PWBIBX) are secured using hardware kits (e.g., PWBHK) and bolted splices to maintain structural integrity and cable protection .Materials and FinishesConnecting pieces are typically made from welded steel or high-strength steel wire and are offered in finishes such as:Powder-coated black or whiteElectro-zinc plated These finishes provide corrosion resistance suitable for data centers, industrial, and enterprise environments .Installation GuidelinesBolted splices require alignment of tray ends and fastening with bolts to secure the connection.Push-on splices are simply pressed into place for quick assembly.Flat expansion bars are inserted to bridge gaps and may require minor adjustments to fit tray widths.Elbow and intersection brackets involve cutting and folding tray sections to form 90° bends, then securing with hardware kits and splices .Key ConsiderationsEnsure compatibility with the tray type (wire basket, ladder, or solid-bottom).Verify load capacity and support span according to tray specifications.Maintain proper alignment to prevent cable damage and ensure smooth transitions.Follow UL or CE standards for electrical bonding if required . These connecting pieces provide a versatile and reliable solution for assembling and modifying pipe or cable tray systems in various industrial and commercial applications.
