Stainless Steel pipe is commonly used to transport fluids and gases. It is produced in different sizes and has many uses such as in wastewater systems, food & beverage facilities, chemical processing, oil and gas processing, and more.
It is produced in different sizes and has many uses such as in wastewater systems, food & beverage facilities, chemical processing, oil and gas processing, and more.
Stainless steel pipe is non-hygienic as it is hot rolled, which means it is heated up and then rolled through a mill into shape. This leaves it with a rougher surface, which is often dull and referred to as a mill finish. Unlike tube, pipe is always round.
You can tell the difference between pipe and tube due to the wall thickness and surface finish. Pipe is thicker and has a rougher finish than tube.
Pipe is measured by Nominal Bore (NB) and Schedule. The term NB (Nominal Bore) is often used interchangeably with NPS (Nominal Pipe Size). ‘Nominal’ is a non-dimensional number that identifies the internal diameter. The wall thickness of pipe is determined by the schedule.

Concentric vs Eccentric Reducers | Technical Tuesday
Concentric and eccentric reducers are used to join two different sizes of pipe or tube. Concentric reducers derive their name from their cone-like shape and have ends on the same axis. Whereas eccentric reducers have a straight side and a cone shaped side. Watch Morgan discuss the difference between these reducers.
How We Send Long Lengths
Watch as Jed discusses how we pick, pack and send your long lengths to you.
What Is Pipe?
Stainless Steel pipe is commonly used to transport fluids and gases. It is produced in different sizes and has many uses such as in wastewater systems, food & beverage facilities, chemical processing, oil and gas processing, and more. Watch Jessie discuss what pipe is and what pipe we stock.
What Is the Difference Between Butt Weld vs Socket Weld Pipe Fittings? | Technical Tuesday
A socket weld fitting fits over the outside of the pipe it is being welded to whereas a butt weld is the welding of two of the same sized diameters joined end to end. Watch Huntley explain the difference.
Our Range of Socket Weld Fittings
Socket weld fittings are used with schedule pipe, which fits into the recess of the fitting and then a fillet weld can be used to join them. Watch Frank as he discusses our range of Socket Weld Fittings.
What is Pipe Schedule? | Technical Tuesday
Pipe Schedule is the standard method to define the thickness and pressure rating of pipe. Watch Huntley explain the correlation between schedule number and thickness of pipe and other components to note.
Our Range of Pipe Fittings
Pipe fittings come in a range of different sizes and shapes to suit your pipe line configuration and are used to join it together to transfer liquids. Sinead will take you through The Metal Company's range and show you how they work.
What Is The Difference Between Tube and Pipe? | Technical Tuesday
Watch Huntley demonstrate the differences between tube and pipe. From the look and feel to the measurements needed to identify the products.

Pipe Schedule is the standard method to define the thickness and pressure rating of pipe and is different to the nominal bore.
Typically stainless in New Zealand is available in Schedule 10, Schedule 40 and sometimes in Schedule 80. The higher the schedule number is, the thicker the pipe is and the more pressure it can handle. It is worthwhile to note, the outside diameter of the pipe doesn’t change, only the wall thickness and inside diameter. For example at 50NB, Schedule 10 and schedule 40 both have an OD of 60.33mm but schedule 40 has thicker walls and a smaller Internal Diameter.
Schedule pipe typically has a welded seam and is therefore technically non-sanitary. The process to manufacture schedule pipe is referred to as hot rolling which implies rolling stainless steel at high temperatures to form into the desired shape. As the stainless steel cools down the metal can naturally contract, therefore accuracy is difficult to control.
The term NB (Nominal Bore) is often used interchangeably with NPS (Nominal Pipe Size). ‘Nominal’ is a non-dimensional number that identifies the hole diameter. The wall thickness of pipe is determined by the schedule. Pipe fittings are available from The Metal Company in Schedule 10S and Schedule 40S. In the engineering industry, this can also be written or referred to as ‘SCH10’ or ‘S10’ and ‘SCH40’ or ‘S40’.
Aside from the pipe fittings range, The Metal Company offers professional schedule pipe fabrication and BSP threading. We have nominated welders able to create customised fittings, providing you with a quick and easy installation on site. Customisation can include extended barrel nipples, extended weld nipples and female BSP threading.
Typical industry applications for schedule pipe and fittings include transporting fluids, gases, drainage & services, irrigation, pumping, petrochemical, geothermal, marine, agriculture and on machinery.

In the world of engineering and construction, the acronyms RHS, SHS and CHS are often used. This is most common in the United Kingdom and associated countries, including Australia and New Zealand.
The term RHS stands for Rectangular Hollow Section. RHS is the most prevalent term and is generally accepted for describing square hollow section as well, which is technically incorrect.
These terms are widely used to describe mild steel; however, they can also be translated for stainless steel and aluminium engineering and construction by engineers who are familiar with the terminology.
Other common terms include Box Section, Extrusion and Profile. Box Section can refer to either rectangle tube or square tube. Extrusion and Profile are terms that can be used in place of ‘Section’; however, this is more applicable to material which has been particularly configured or shaped rather than rectangle, square or circular hollow tube.
The Metal Company stock a full range of SHS, RHS & CHS in 304 & 316 Stainless Steel.
