ASTM B464 - Welded Pipes
ASTM B464 Welded Pipes which are covered under standard ASTM B464 specification, which are made from flat rolled sheet stock of material. These Flat sheets of material are then rolled through an automatic welding process where no addition of filler metal is done. The Welded Pipes are further subjected to heat treatment, where it should be furnished in stabilized annealed conditions. This ASTM B464 is standard specification which covers ASTM B464 Alloy 20 Welded Pipes (ASTM B464 UNS N08020 Welded Pipes) which are intended for application in general resistance towards corrosion and applicable at low or high temperature environments. These ASTM B464 Welded Pipes are well-known for their high mechanical strength, excellent resistance towards creep deformation, good surface stability and resistance towards oxidation or corrosion. The length are single random, double random and cut length. Ends given to pipe are Plain end, Beveled end, Threaded end.
Scope And Manufacturing
The ASTM B464 Alloy 20 Welded Pipes should adhere to all the specification as mentioned in ASTM B464, like its chemical composition, mechanical properties and dimension standards. As per specification, it should adhere to chemical composition requirement for carbon, manganese, sulfur, phosphorous, nickel, silicon, copper, chromium, molybdenum, columbium, tantalum, niobium, nitrogen and iron.

Mechanical Properties And Other Requirements:-
The ASTM B464 UNS N08020 Welded Pipes should adhere to the mechanical properties as specified in ASTM B464 specification like, tensile strength, yield strength, elongation, rockwell hardness and also should be tested for the following test like, flattening test, non-destructive test, and transverse guided bend test.
|Grade||Tensile Strength, min, psi (MPa)||Elongation 2inches or 50.8mm or 4D min, %||Yield Strength (0.2% offset)|
ASTM B464 Pipe covers, nominal pipe sizes up to and including NPS 6 [168 mm] with the nominal wall thicknesses given as Schedules 5S, 10S, and 40S and nominal pipe sizes up to and including NPS 2 [60 mm] also including Schedule 80S.
Flare Test: - The Flare test should consist of test specimen (one end of tube among the lot of 100) with the help of expanding tool having covering an angle of 60 degree, until the specified outside diameter of the tube is increased atleast by 30% from the original. During this process, the tube should not exhibit any cracking through walls.
Grain Size: - An n extended (transverse) sample exhibiting complete wall thickness of annealed alloys shall adhere to the average grain size as specified in ASTM B464 specification.
Hardness: -In stress-relived conditions when annealed ends are specified for tubing, the hardness of the ends should not cross the limits as specified in ASTM B464.
Flattening Test: - From every lot, each end of one pipe should be subjected to a flattening test. Rejections should not be due to superficial ruptures resulting from surface imperfection.
Hydrostatic or Nondestructive Electric Test: - Every tube should be put through either hydrostatic test or nondestructive electric test. Within the mentioned specification limits of outside diameter of 1/8 inches (3.2mm) and thickness of 0.015 inches (0.38mm), each tube should be tested to an internal hydrostatic pressure of 1000 psi. (6.9MPa). Fiber stress calculated using this formula should not exceed the specification limits.
Transverse Guided Bend Test:- This test may be subjected on pipes as substitute, instead of flattening test. Two bend specimens should be taken transversely from pipe or from the material sheet itself and hest as pipe, which is attached to end of cylinder and welded as prolongation of the pipe longitudinal seam. Minimum one test is required for each lot as defined by specification.
Specimen Preparation: -
Tension test- The tubes in the final condition (temper) of production are taken as specimen for tension test, and are tested in the direction of fabrication. Tubes are tested in full tubular size or longitudinal strip with reduced gage lengths. The tension test should be performed on stress-relived tubes prior to annealing the ends.
Hardness test- The hardness test is performed on the inside of the tube near the end or on the specimen cut from the end.
Workman Ship, Finish and Appearance: -
ASTM B464 Welded Tubings are individually covered so that the premium quality of material is retained and there are no damages in the last stages of production. The Tubings should be uniform in quality and temper, commercially straight, smooth and free of any imperfections.
Inspection: - The tubes should be inspected as agreed upon by the purchaser and the manufacturer.
Rejection and Rehearing: - The tube not adhering to the ASTM B464 specification or to authorized modifications should be subjected to rejection. The rejected specimens should be preserved for not less than 3 weeks from test report, and the manufacturer may claim for rehearing within that stipulated time period.
If it is mentioned in purchase order or the contract, then the manufacturer should be able to produce a certificate stating that the material has been manufactured and tested and inspected again with respect to the specification. It should also note the test results of the specimen samples which meets the specification requirements, and should be displayed as and when required.
ASTM B464 Welded Tubes are tagged along with the imprints relevant to the job information which also contains information about the delivering destination like heat number, size, material, and part number.
