Quality and Mechanical Tests:

To assure the highest quality standards, the tubing is subjected to extensive testing and inspection programs that meet or exceed ASTM A270 A1016 A1016M test requirements. Testing includes reverse bend, reverse flattening, and flange tests. Eddy current testing is performed on 100% of the sanitary tube produced.
Heat Treatment (Annealing):
Inline hydrogen bright annealing to 1900°F (1040° C) minimum followed with a rapid quench.
Surface Finishes
Surface finish is 20 µ-in Ra (0.5 µm) ID maximum, 30 µ-in Ra (0.8 µm) OD maximum surface roughness measured per ASME ANSI B46.1 with the profilometer reading at 90 degrees to the lay. Other finishes available upon request.
Flattening Test
For material heat treated in a continuous furnace flattening tests shall be made on a sufficient number of pipes to constitute 5% of the lot, but in no case less than 2 lengths of pipe.
Markings
Bright annealed tubing is line-stenciled with OD, wall, ASTM specifications, size, grade, heat number, production date and time. OD polished tube is marked on one end of each tube with a removable label stating ASTM specification, manufacturer, grade and heat number. Continuous line stencil available on request.
Note:
Mill test certificates will be issued according to EN10204.3
All tubes shall be supplied as per applicable ASTM A270 /A270M Specification.
 

MARKS

At last, the mark should furnished in accordance with A 1016/A1016M, and specified in the order. Includes the sanitary stainless steel pipe manufactured in Seamless (SML), Welded (WLD) or heavily cold worked (HCW).
 

PACKAGE

Before delivery, all steel pipes should bundled well, and covered by paper, cloths. Or packed in box by manufacturer.
 

ADDITIONAL REQUIREMENTS

In case specified in the order, intergranular corrosion tests shall be performed by manufacturer on specimens representative of the as-shipped condition. Sanitary stainless steel pipe and tube shall be capable of passing corrosion tests in the as-shipped condition. For austenite alloy steel should meets the Practice E of the standard A262 , and for duplex alloy steels (S31803, S32205 and A32750) should meets experiment C of Test Methods A 923.
In case the ASTM A270 stainless steel pipe for pharmaceutical quality applications, it is more strict on the chemicals, strengths and size tolerances.
ASTM A270 covers grades of seamless, welded, and heavily cold worked austenitic and ferritic/austenitic stainless-steel sanitary tubing. Seamless tubes shall be manufactured by a process that does not involve welding at any stage. Welded tubes shall be made using an automated welding process with no addition of filler metal during the welding process. Heavily cold worked tubes shall be made by applying cold working of not less than 35% reduction of thickness of both wall and weld to a welded tube prior to the final anneal. No filler shall be used in making the weld.
All material shall be furnished in the heat-treated condition. A chemical analysis of either one length of flat-rolled stock or one tube shall be made for each heat. Each tube shall be subjected to mechanical tests like reverse flattening test, hydrostatic test or nondestructive electric test.
The following surface finishes may be specified: mill finish, mechanically polished surface finish, finish No. 80, finish No. 120, finish No. 180, finish No. 240, electropolished finish, and maximum roughness average surface finish. Longitudinally polished finish shall be performed on the inside surface only while a circumferential polished finish shall be done on either the inside surface, outside surface, or both.
