K52000-22 - HELIX 22-Inch Orbital Track Ring with 8 Shoes

Product Overview

The Lincoln Electric K52000-22 is a specialized Track Ring designed for use with the HELIX™ orbital welding system. Engineered to fit 22-inch (558.8 mm) nominal pipe sizes, this component serves as the foundational guide for the orbital weld head, allowing for mechanized travel around the circumference of the pipe. The unit is constructed with precision-machined surfaces and an integrated gear rack that interfaces directly with the drive mechanism of the HELIX weld head, ensuring consistent travel speeds and accurate positioning essential for code-quality welds.

This specific model is equipped with 8 mounting shoes. These shoes are critical for establishing a secure concentric fit on the pipe surface. They are designed to accommodate slight variations in pipe geometry, such as ovality or surface roughness, which are common in large-bore industrial piping. The shoes provide the necessary standoff distance and thermal isolation, protecting the track mechanism from the direct heat of the arc while maintaining rigidity. The K52000-22 is manufactured from durable materials capable of withstanding the harsh environments typical of pipeline construction, power generation facilities, and heavy fabrication shops.

Integration with the HELIX system allows for both MIG and TIG orbital welding processes. The track ring's design facilitates rapid installation and removal, a key factor in reducing downtime between joints. The locking mechanism ensures that once positioned, the ring remains immobile relative to the pipe, providing a reliable reference for the welding torch. This part is an OEM replacement or expansion component for existing HELIX system operators requiring 22-inch pipe capability.
