Tubes and Fittings

High-Purity Gases

Surface treatment, inspection from arrival to delivery, and storage of stainless steel tubes, fittings, and valves for high-purity gas systems. All to ensure high standards of quality.

Quality Control Throughout the Chain

The entire refinement process, from arrival inspection to delivery, takes place in Calamo’s spacious and protected facilities. This ensures full control over quality and lead times throughout the chain.

Clear Procurement and Inspection Procedures

All raw material purchases are made according to procurement specifications to ensure the product meets all required standards. Arrival inspection covers the chemical analysis of the steel, tolerances, surfaces, labeling, packaging, and material certificates. Everything is recorded in the ERP system, and production follows well-established and documented processes.

Surface Treatment According to Specific Needs

The surface treatment process is tailored to each individual product and is well-documented. All Calamo employees work according to controlled regulations. Storage takes place in our temperature-controlled indoor warehouse, where we deliver according to the FIFO principle. Depending on the product, the tubes are protected with nylon film, PE plugs, and single or double PE socks. The tubes are delivered in well-protected and treated wooden packaging approved for export.
