The Basics on Schedule Pipe Fittings

All the applicable schedule pipe fittings are manufactured to standard ASME B16.

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’.

The Metal Company stock a range of schedule pipe fittings including 45° & 90° bends, concentric & eccentric reducers, end caps, tees, sockolets and threadolets.

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.
