Stainless steel are iron-based alloys usually containing at least 11.5% chromium. Other elements, Nickel being the most Important, may be added in combination with chromium to obtain special properties. Stainless steel are highly resistant to corrosive attack and to oxidation at high temperature. in general, corrosion resistance and oxidation resistance increase progressively, though not proportionately, with the increase in chromium content.
Stainless steel pipe and tubing are used for a variety of reasons: to resist corrosion and oxidation, to resist high temperature, for cleanliness and low maintenance costs, and to maintain the purity of materials which come In contact with stainless. The inherent characteristics of stainless steel tubing permits the design of thin wall piping systems without fear of early failure due to corrosion. The use of fusion welding to join such piping eliminates the need for threading.
Type 304 stainless steel is the most widely used analysis for general corrosion resistant tubing and pipe applications, it is used in chemical plants, refineries, paper mills, and food processing industries. Type 304 has a maximum carbon content of .08%. It is not recommended for use in the temperature range between 800°F and 1650°F due to carbideprecipitation at the grain boundaries which can result in intergranular corrosion and early failure under certain conditions.
Type 304L stainless steel. Is the same as 304 except that a .03% maximum carbon content is maintained which precludes carbon precipitation and permits the use of this analysis in welded assemblies under more severe corrosive conditions. Type 318 is much more resistant to pitting than other chromium nickel alloys due to the addition of 2% to 3% molybdenum it is particularly valuable wherever acids, brines, sulphur water, seawater or halogen salts are encountered. Type 316 is widely used in the sulphite paper industry and for manufacturing chemical plant apparatus, photographic equipment, and plastics.
Type 316L stainless steel, like 304L, is held to a maximum carbon content of .03%. This permits its use in welded assemblies without the need of final heat treatment. It is used extensively for pipe assemblies with welded fitting..
Other fields where stainless steel pipe and tubing are used are: aviation, electronics, automotive, cyrogenic, marine, air conditioning and heating, medical, architectural and textiles.

Stainless Steel Pipe Specification:
Scope:
Pipe intended for high temperature and general corrosive service as in A-312, plus electric fusion welded pipe as in A-358 and intended for high temperature and general corrosive service or both.
General Requirements:
Conforming to the above specifications plus applicable parts us ASTM A-530.
Range:
ASTM A312 pipe is more commonly found from 1/8″ IPS to and including 24” NPS in standard SCH5, SCH10, SCH20, and SCH40. On special application, sizes can be produced to 60” lPS through schedule 80 walls by certain mills. ASTM A358 is usually produced in sizes 8” IPS and larger and where filler metal is added to the weld. This specification covers five classes of pipe and are usually determined by the end application and needs of the pipe.
ASTM A312 pipe is manufactured by two different processes. Pipe through 6” IPS is manufactured by the continuous welding process and is very similar to welded tubing. Coils of flat roll strips are fed into sizing rolls and welded. Material is then annealed (usually in an open air furnace), straightened, cut, pickled, tested, and inspected. In full finished pipe, material is cold worked after welding. This can be done by rolling, forging, or drawing the weld bead; but primarily the weld is rolled.
Pipe 8” IPS and larger is manufactured by the batch method or process. Unlike the continuous welding method. material made by this batch method is made in single lengths. Plates, cut to length and width, are formed from flat into tubular shape by a press and welded. Material is then annealed, sized, and straightened, ends trimmed or cut to specific smaller lengths, pickled, and inspected.
Pipe and Tubing
“As-Welded” Grade “
“as-welded” pipe and tubing is straight-seam welded using ASME qualified automatic gas tungsten-arc procedures andcan be supplied in a wide range of diameters and wall thicknesses from any of the weldable corrosion resistant alloys. Normally furnished with square cut ends, pipe with beveled, belied, or roil-grooved ends can be provided. Spot radiography or 100% radiography of welded seams can also be performed. pickles and passivates its pipe and tubing to maintain corrosion resistance and to prevent surface discoloration from free iron oxidation. “As-welded” pipe and tubing is commonly used in pulp and paper mills, food processing plants. and other industries where corrosion resistance is essential.
This specification covers welded unannealed stainless steel tube intended for low to moderate temperatures and corrosive service where heat treatment is not required for corrosion resistance. A 788 is considered to be the most applicable ASTM specification for “as welded” pipe and differs from it only in that a transverse guided-bend test and a transverse tension test are required per lot.
