Tube

Tube is commonly used for a wide range of purposes including food & beverage process lines & structures, irrigation, pumping, petrochemical, geothermal, marine, agriculture and machinery, automotive, and architecturally. It serves as the vital network of distribution for the safe and regular flow of liquids and gases, and as the solid structural basis for all kinds of industrial and agricultural applications. Tube is cold rolled which means that it has been rolled from a stainless-steel coil while cold. This results in a smooth, hard finish. It is normally finished with a 180 or 320 grit polish, although it can also be polished to even smoother finishes. It comes in different shapes such as square, rectangular and cylindrical.

Diameter is measured based on the OD or outside diameter and wall thickness.

We stock a variety of tube for a variety of applications (including dairy and general-purpose tube), shapes (including round, square, and rectangle tube), and ease-of-installation, such as our press-fit tube.

Round tube can be polished internally to make it hygienic, which is commonly known as Dairy Tube in New Zealand. Ours is manufactured to the AS1528.1 Standard and uses imperial inch sizing, so its commonly known as 1”, 2” tube, etc. 

General Purpose is the same as Dairy Tube, but the weld seam hasn’t been polished. It’s also commonly known as handrail tube. This makes it a more economical alternative for non-hygienic applications such as glycol or handrails. 

Both Dairy and  General Purpose tube is polished to a 320 grit and are available in 304 & 316 grade stainless steel. We stock Dairy from ¼” to 8”, and General Purpose from 1” to 8”. 

Square and Rectangle tubes are commonly used for building structures and frames. They are polished to a 180-grit finish making them an ideal material for use in clean environments. We stock a range of sizes and thicknesses from ½” Square tube right up to 150x100x5 Rectangle tube in 304 & 316 Grade Stainless.

Press-fit Tube is measured metrically and fits our press-fit system. This is available in both 304 & 316 from 15mm to 108mm. We can get bigger sizes up to 168mm as needed.
