We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
The pipe should be lowered progressively with the help of shear legs or cranes utilizing wide belts or slings. In case of coated pipes, additional care shall be taken to preserve the coating whereas lowering.
We additionally provide competitive range of ss 304 pipes & tubes in shoppers requirement. The inside strain is not the only criterion for use in figuring out the wall thickness. Where water to be conveyed is aggressive in nature, the pipeline ought to be provided with an internal coating or lining, Such linings are normally of bitumen, coal tar, epoxy resin, concrete or cement mortar or plastic lining. Care should be taken to see that the fabric used for coating is non-toxic.
Physical Properties Of Ss A312/a249 Tp 304 Welded Pipes And Tubes
The steel pipe data chart below can be utilized to seek out pipe sizes, diameters, wall thickness, working pressures and extra The chart is predicated on ASME/ANSI B 36.10 Welded and Seamless Wrought Steel Pipe and ASME/ANSI B36.19 Stainless Steel Pipe. Stainless steel pipe is most frequently available in normal weight sizes (noted by the S designation; for instance, NPS Sch 10S). However stainless-steel pipe can be out there in other schedules. Stainless metal pipes, which were coming into more frequent use within the mid twentieth century, permitted the usage of thinner pipe walls with a lot less danger of failure due to corrosion. By 1949 thinner schedules 5S and 10S, which have been based on the stress requirements modified to the nearest BWG number, had been created, and other “S” sizes followed later.
- NPS is commonly incorrectly known as National Pipe Size, because of confusion with the American standard for pipe threads, “national pipe straight”, which additionally abbreviates as “NPS”.
- The European and worldwide designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimetres, see ISO 6708.
- Standard Description ASTM A312/A312M Seamless and welded austenitic stainless-steel pipe.
- Nominal Pipe Size (NPS) is a North American set of ordinary sizes for pipes used for prime or low pressures and temperatures.

Where growth joints are provided, it’s necessary to create restraining factors on the pipeline to make sure proper functioning of these joints. The pipe laying work should ideally begin from the restrained points on cither facet working in direction of centre where the enlargement joint ought to be fitted final. Provision of expansion joint at intervals of 300 m on uncovered metal pipeline is mostly really helpful. Expansion joints ought to at all times be supplied between two fixed supports or anchorages (see 8.3.three).
What is code in piping?
The classification of pipes are schedule and nominal diameter. Pipe is typically ordered using the Nominal Pipe Size (NPS) standard and by specifying a nominal diameter (pipe size) and schedule number (wall thickness).
See pipe dimensional table, Specification ASME B36.10M or B36.19M for pipe dimensions per schedule. Anchors are provided on the pipeline on the place of line valves or sectionalizing valves, on the clean flange, at the tapers and on the mid-point between two consecutive growth joints, within the case of above floor pipeline. Each valved part of the pipe shall be slowly filled with clear water and all air shall be expelled from the pipeline by way of hydrants, air valves and blow-offs fastened on the pipeline. Before beginning the strain test, the growth joints must be tightened.
ASTM A249/A249M Welded austenitic steel boiler, superheater, heat exchanger and condenser tubes. ASTM A269 Seamless and welded austenitic chrome steel tubing for common purposes. ASTM A270 Seamless and welded austenitic stainless-steel sanitary tubing.
Under the take a look at stress no leak or sweating shall be visible at all part of pipes, fittings; valves, hydrants and welded joints. Any defective pipes, fittings, valves or hydrants found in consequence of this pressure take a look at shall be eliminated and changed by sound materials and the check shall be repeated till passable to the Authority.
