ASTM B467 - Welded Pipes and Tube

ASTM B467 Welded Pipes and made from coiled plate of steel with specific width and thickness, which are put through series of rollers and then welded in form of pipe tube that adheres to the relevant specification i.e ASTM B467. Electric Resistance Welded Pipes (ERW Pipes) are cold formed. The ribbion or the coiled steel plate is pulled through a series of rollers that gradually forms, into a cylindrical tube. Now the edges of steel plate come together and an electric charge is applied at the proper points to heat the edges so they can be welded together to form a pipe. ERW pipes tubes is a product of very high speed production, which are uniform in thickness and dimensions and can be formed in continuous lengths.

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 B467 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 B467.

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.

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 B467 Seamless 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 B467 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 B467 Seamless 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.
