Description

A249 TP304L Stainless Steel Pipes/Tubes Manufacturers & Suppliers in India

Largest Manufacturer and Suppliers of Welded Austenitic Steel Boiler, Superheater, Heat Exchanger, and Condenser Tubes of ASTM A249 TP304L specification. Metallica manufactures stainless steel tubing from the finest quality raw materials. Stainless steel tubes in grade TP304, TP304L, TP316, TP316L and TP201 are generally available in stock in size range of  1/8” NB to 5” NB, 1/4” OD to 5” OD sizes.

Stainless Steel Grade 304 is the most commonly used stainless steel. 304 Stainless Steel belongs to the family of Austenitic Stainless Steel in which pure iron has existence only at a steady temperature range of 910º – 1400º Celsius. It doesn’t display magnetism, but it is austenitic, corrosion resistant steel with excellent strength, tough, fabrication characteristics and weldability. SS 304L is the low carbon version of SS 304 may be required for full corrosion resistance when thicker sections are welded.

Quality and Mechanical Tests for Stainless Steel Pipes & Tubes as per ASTM A249 TP304L

To assure the highest quality standards, the tubing is subjected to extensive testing and inspection programs that meet or exceed ASTM A249 TP304L test requirements. The steel shall undergo mechanical tests such as tension test, flattening test, flange test, reverse-bend test, hardness test, and hydrostatic/eddy current testing/nondestructive electric test. The grain size of different grades of steel shall be determined in accordance with the test methods.

Heat Treatment (Annealing) for Stainless Steel Pipes & Tubes as per ASTM A249 TP304L

A249, A269 and A270  follows that “all material shall be furnished in the heat treated condition”. Heat treatment is annealing (also referred to as solution treatment or solution annealing). In practice this is not a common requirement for food industry tube unless it requires significant bending or flaring. All materials shall be furnished in the heat-treated condition in accordance with the required solution temperature i.e. minimum of 1900 degrees F and quenching method. A249 TP304L requires that at least the weld be cold worked after welding and before final heat treatment. When the final heat treatment is in a continuous furnace, the number of tubes of the same size and from the same heat in a lot shall be determined from the prescribed size of the tubes.

Surface Finishes for Stainless Steel Pipes & Tubes as per ASTM A249 TP304L

The tubes, after heat treatment, shall be chemically descaled or pickled free of scale. Pickling or chemical descaling is not needed if bright annealing is used.

Flattening Test for Stainless Steel Pipes & Tubes as per ASTM A249 TP304L

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 for Stainless Steel Pipes & Tubes as per ASTM A249 TP304L

Manufacturer Name or brand, specification number and grade on tube. For tubes less than 1 1/4″ in diameter or under 3″ in length, a tag may be secured to the box or bundle.

Note:

  • Mill test certificates will be issued according to EN10204.3
  • All tubes shall be supplied as per applicable ASTM A249 /A249M Specification.
