Stainless Steel Tubes Precision Welded. Built to Perform.

SOLE manufactures high-performance laser welded stainless steel tubes at our cutting-edge facility in Norway. Built for precision and durability, our tubes are used across the HVAC industry, mechanical systems, and energy applications. With inline bright annealing and advanced quality control, we deliver consistent results—whether you need a few meters or a 49-meter custom tube.

We produce tubing primarily in 1.4521, AISI 316L, and AISI 304, with flexible dimensions and surface finishes to match your application. All of our tubes are made from 95% recycled stainless steel, produced using 100% renewable energy – combining technical excellence with environmental responsibility.

Tube Bending & End Forming Capabilities

In addition to manufacturing high-quality stainless steel tubes, SOLE offers in-house bending and end forming services to meet complex design and installation requirements.

Our advanced machinery and tooling systems allow us to form precise geometries across a wide range of materials—including stainless steel, brass, aluminum, and carbon steel.
Whether you require tight-radius bends, multi-plane configurations, or specific end shapes (flaring, swaging, beading, or custom profiles), we deliver repeatable and production-ready results.

By handling both tube production and post-processing under one roof, we reduce lead times, ensure dimensional accuracy, and simplify the supply chain for our customers. This makes SOLE a flexible and reliable partner for OEMs in HVAC, water heating, and industrial system integration.
