Product Insights

Size & Shape

Tube dimensions include the outside diameter, inside diameter, wall thickness, and length. Nominal sizes for metal tubes are typically based on the outside diameter. Standards organizations such as ASTM and ASME specify tolerances and other requirements in conjunction with material dimensions, outlining the permissible measurement variation allowed to meet specific standards. Tubing shapes include circular, oval, rectangular, and square, with custom shapes also available.

Finishes

• Bright Finish – The tube undergoes secondary finishing processes such as polishing or pickling, resulting in a bright surface.
• Galvanized – A zinc coating is added to the tube to enhance corrosion resistance.
• Painted – The tube is either painted or powder-coated to resist corrosion or for identification purposes.

Specialty Tubing

• Chromoly Tubing – Known for its strength and durability, chromoly tubing is used in applications where strength-to-weight ratio is important, such as in the motorsports and aerospace industries.
• Sanitary Tubing – Designed for applications requiring high cleanliness and corrosion resistance, sanitary tubing is ideal for industries like pharmaceuticals, food processing, and biotechnology.
• Honed ID Tubing – Honed ID tubing has a smooth interior surface and precise inside diameter dimensions. It is used in hydraulic and pneumatic cylinder applications where precise tolerances and a polished finish are required.
• Driveline Tubing – With a tighter straightness tolerance and engineered for automotive and heavy-duty equipment, driveline tubing provides robust support in the transmission of power between components for efficiency and reliability.
• Carbon and Stainless Hydraulic Fluid Line – Hydraulic fluid line tubing, available in carbon and stainless steel, is designed to withstand high-pressure applications, making it a staple in hydraulic systems across various industries.
• Boiler Tubing – Boiler tubing is engineered to withstand high temperatures and pressures, making it a crucial component in boilers and heat exchangers, ensuring efficient heat transfer in industrial processes.
