There is no single tube or pipe bending process that works for every application. The material, size, and complexity of the bend determine the appropriate equipment and method. Common techniques include rotary draw bending, roll bending, compression bending, and freeform bending. Every bend has three radii to consider: the centreline radius (CLR), the inside radius, and the outside radius. The CLR represents the neutral axis of the tube or pipe, where there is no material compression or expansion. Each bending method manipulates various factors to achieve the desired result while maintaining the designated CLR.

Rotary draw bending and compression bending both form the tube around a die, but the way the pipe wraps around the die differs. Rotary draw bending typically requires a mandrel inside the tube to prevent defects—hence it is also called mandrel bending. Mandrel bending is especially effective for creating tight-radius bends in thin-walled tubes and pipes.

In both rotary draw and compression bending, the bend die size sets the CLR. In contrast, for roll bending and freeform bending, the CLR depends on how the tooling moves, not its size. No single method is inherently superior; each has applications best suited to specific materials and bend requirements. A professional with experience can determine the most efficient and cost-effective method for each project.

Much of modern pipe bending focuses on pipe coiling, where a tube or pipe is guided through a machine to create a continuous helix or spiral. Used in both industrial and decorative applications, these custom-formed pipes often go unnoticed for the intricate manufacturing process required to produce them.

Linmar Pipework specialises in section bending, delivering precision-formed pipes and tubes tailored to a wide range of industrial applications. With years of expertise, Linmar combines advanced equipment with skilled craftsmanship to produce accurate, reliable bends while maintaining material integrity. Their team works closely with clients to meet specific project requirements, offering flexible solutions for both standard and complex pipework designs.

Coded welding has long been a core service at Linmar Pipework. Beyond standard pipework installation, the company designs, repairs, and manufactures specialised equipment requiring all types of welding, including coded welding. A coded welder is someone who has successfully completed an industry-recognised examination, demonstrating their skill and competence in a specific welding technique or configuration.

With expertise across all aspects of pipework installation and materials, we collaborate closely with each client to achieve the best possible results. From installing new compressed air, gas, or water pipelines to delivering complete factory ring mains, including the renewal or maintenance of existing systems, we provide reliable, tailored solutions to meet every project need.

Linmar Pipework offers expert steelwork fabrication, delivering high-quality, precision-engineered structures to meet a wide range of industrial needs. Combining skilled craftsmanship with advanced machinery, Linmar designs, manufactures, and assembles steel components tailored to each client’s specifications. From structural frameworks to bespoke steel assemblies, their team ensures durability, accuracy, and efficiency, providing reliable solutions for both standard projects and complex custom requirements.
