A stainless steel pipe system is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. Due to stainless steel’s aesthetic properties, stainless steel pipe is also used in architectural applications.
Stainless steel pipe can be generally defined as a heavy wall thickness tubing, with dimensions as specified by the American National Standards Institute (ANSI). Pipe dimensions are specified by outside diameter – indicated by the NPS (imperial) or DN (metric) designator and sometimes confusingly referred to as the ‘nominal bore’ – and wall thickness, reflected in the schedule number. ASME B36.19M covers these dimensions.
Stainless steel pipe and fittings are supplied in the annealed condition to facilitate fabrication and ensure best corrosion resistance. Fitwel Industries LLP can also supply stainless steel pipe with an abrasive polished external finish suitable for architectural applications.
Welded stainless steel pipe is manufactured from 2B or HRAP stainless steel strip – formed to shape, longitudinally welded and annealed.
Large size pipe is fabricated from plate.
All welds are made without the addition of filler metal, except for very large diameters.
Standard welded pipe is in nominal lengths of 6.0 or 6.1 metres.
Seamless stainless steel pipe is produced from hollow billets, which are pierced then usually cold drawn until they reach the final desired pipe size, then annealed.
Standard seamless pipe is supplied in nominal lengths of 6.1 metres to DN 150 (NPS 6) and above this in random lengths.
Stainless steel piping systems can be joined by butt welding and, in the heavier 40S and 80S schedules, by threaded connections.
The complete piping system is made possible using complementary fittings and flanges. These are specified by the same DN or NPS designator and schedule numbering system as for pipe.
A piping system using butt welding fittings has many inherent advantages over other forms.
Buttwelding fittings can be supplied in either seamless or welded construction and are covered by specification ASTM A403M (or ASTM A815M for Duplex grades) and ASME B16.9.
These are the Standard specifications of Stainless Steel Pipe Fittings. We also manufacture and export any custom specification as per client’s requirement. For any custom specification you can directly qoute your requirents to us.

The reason for choosing stainless steel is normally due to advantages given by physical properties such as corrosion resistance.
In addition to corrosion resistance, the advantageous physical properties of stainless steel include:-
All welded pipe fittings have bevelled ends to allow for ease of welding. This bevel allows for full penetration weld in most cases.
There are two types of bevels;-
Pipe Fittings are known to deliver exceptional performance and are generally developed for meeting the demands. We offer a broad range of ASTM B16.5 Stainless Steel Pipe Fittings through a worldwide network of stock-keeping branches. These ASTM B16.5 Pipe Fittings is use in various industries like :-
