Standard seamless pipe is in random lengths of 6.0 to 7.5 metres. Seamless stainless steel pipe is produced from hollow billets, which are then drawn across dies until they reach the final desired pipe size and wall thickness. ASTM A358M – Austenitic (large diameter).Standard welded pipe is in nominal lengths of 6.0 to 6.1 metres. With the exception of very large pipe welds are made without the addition of filler metal. Welded stainless steel pipe is manufactured from 2B or HRAP stainless steel strip – formed (to shape) and longitudinally welded to completed pipe. Atlas Steels can also supply stainless steel pipe with an abrasive polished finish suitable for architectural applications. Stainless steel pipe and fittings are supplied in the annealed condition to facilitate fabrication and ensure best corrosion resistance. The standard ASME B36.19 covers these dimensions. Pipe dimensions are nominated by outside diameter indicated by the NPS (imperial) or DN (metric) designator and sometimes referred to as the ‘nominal bore’ – and wall thickness, is determined by the schedule number. Stainless steel pipe can generally be defined as a heavy wall thickness tubing, with dimensions as specified by the American National Standards Institute (ANSI). Customized inventories serving local markets are maintained at each branch location. With our corporate offices in Houston, Texas we can handle any size order or project to ship anywhere in the world out of our Stock. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications.

BSP threads have what’s known as a Whitworth thread form – a 55° angle and rounded peaks and valleys. NPT threads have what is called a Sellers thread form, which means they have a 60° angle and flattened peaks and valleys. They are not compatible, as most sizes have a different pitch, as well as different thread forms. It’s very important to note that BSP and NPT threads must never be interchanged if they’re being used for a high-pressure application. Longscrew threads are parallel pipe threads that achieve a tight-pressure joint by compressing a soft material -such as a washer or O-ring seal – between the end face of the male thread and a nipple face or socket by tightening a backnut. The male thread is always tapered, but the female thread can be parallel or tapered. Joining threads are when a pressure-tight joint is made by mating two threads together. BSP threads can be used to form two main types of joints – Joining and Longscrew.
