ASTM B423 - Seamless Pipes and Tube Stockist

ASTM B423 is a standard specification for nickel chromium pipes and tubes, which are composed of nickel-iron-chromium-molybdenum-copper based alloys in the form of cold-worked and hot-finished seamless pipes and seamless tubes intended for general corrosive applications. The chemical composition is such that it provides exceptional resistance to most corrosive environments. The Nickel content in its composition exhibits excellent resistance towards chloride-ion stress cracking corrosion. When nickel is added with molybdenum and copper in its composition, it provides outstanding resistance towards reducing environments such as the one containing sulfuric or phosphoric acid in them. Addition of Molybdenum also helps in resistance towards pitting and crevice corrosion. The chromium content in the alloys composition shows good resistance towards various oxidizing agents like nitrates, nitric acids and oxidizing salts.

If you want assistance with the requirements for ASME SB 423 tubes with hydrostatic and non-destructive electric tests to complete your project, then get in touch with us

Mechanical Properties And Other Requirements:-

Tensile strength, yield strength and elongation of the material under the specified condition and size shall also conform to the required mechanical properties as specified in ASTM B423 specification. Hydrostatic and nondestructive electric tests shall be performed.

Grade Condition Yield Strength, (0.2% offset), min, psi (MPa) Tensile Strength, min, psi (MPa) Elongation in 2 inches or 50 mm (or 4D), min%
Incoloy 825 (UNS N08825) Hot-finished annealed 25 (172) 75 (517) 30
Cold-work annealed 35 (241) 85 (586) 30
Hot-forming quality (hot-finished or cold-drawn annealed)

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 B423 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 B423.

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.

Grade Condition Fiber Stress min, psi (MPa)
Incoloy 825 (UNS N08825) Hot-finished, annealed 16, 600 (114)
Cold-worked, annealed 21, 200 (146)
ASTM B423 material comes with grades including UNS N08825 and N08221 for a reasonable price with value-added services

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 B423 Seamless Pipes and Tubes are individually covered so that the premium quality of material is retained and there are no damages in the last stages of production. The tubes and pipes should be uniform in quality and temper, commercially straight, smooth and free of any imperfections.

Inspection: - The material should be inspected as agreed upon by the purchaser and the manufacturer.

Rejection and Rehearing: - The material not adhering to the ASTM B423 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.

Certification: -

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.

Product Marking:-

ASTM B423 Seamless Pipes and 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.
