Pipe Spiders: The Role of Pipe Spiders in Civil Construction Projects

In the world of civil construction, precision and efficiency are the cornerstones of success. Many infrastructure projects comprise one or more pipes installed inside a larger pipe. The installation of the internal pipes becomes more effective and efficient with the use of pipe spider clamps. Pipe spiders are a structure with rollers attached to the perimeter of the assembly, allowing smaller pipes to be inserted accurately and efficiently inside larger-diameter pipelines while maintaining a consistent annulus inside the parent pipe.

These are commonly used in micro tunnelling, pipe jacking, and pipe-in-pipe a, though other applications can include heat shielding for steam piping, heat exchangers and insulation.

Piper Spider Materials: Galvanised, Stainless, or Raw Steel?

The choice of material finish for pipe spiders is a crucial consideration. Galvanised mild steel pipe spiders are corrosion-resistant, making them well-suited for outdoor construction projects where exposure to the elements is a concern.

Stainless steel pipe spiders offer exceptional corrosion resistance and are often chosen for applications in harsh environments or where hygiene is paramount. 

Raw steel pipe spiders, though lacking corrosion resistance, are a cost-effective choice for projects where a protective coating will be applied separately or it is for a single-use application.

Roller Material: Neoprene or Steel?

Pipe spiders come in different configurations, often categorised by the materials used in their construction. Neoprene pipe rollers are favoured for their flexibility and resilience. They are gentle on pipe surfaces, making them suitable for pipes with delicate coatings or finishes. On the other hand, steel rollers, are a robust and durable option, are ideal for heavy-duty applications. They provide a solid grip on pipes, ensuring stability during lifting and placement. Other materials used for rollers include Nylon, HDPE or UHMWPE, depending on the application

Rubber Lining for Pipe Coating Protection

Preserving the integrity of pipe coatings is a top priority in construction projects, as these coatings are essential for preventing corrosion and maintaining pipe longevity. Pipe spiders often come equipped with a rubber lining to protect these coatings during handling and placement. This rubber lining acts as a cushion, preventing scratches, abrasions, or any damage to the pipe’s protective layer. Preserving the coating ensures the long-term functionality and durability of the pipe system.

Pipe spiders are invaluable tools in civil construction projects, with a range of options to suit specific needs.

Whether you opt for neoprene or steel rollers, or choose from a galvanised, stainless, or raw steel finish, the primary goal remains the same: to facilitate the secure placement of internal pipes, maintaining the correct annulus inside the parent pipe. The inclusion of rubber lining further underscores the commitment to safeguarding the pipe’s protective coatings.

With their versatility and ability to protect sensitive pipe surfaces, pipe spiders prove themselves as essential assets on construction sites, contributing to the successful completion of projects while ensuring the longevity of the infrastructure they support.
