ASTM A53 galvanized steel pipe refers to the steel pipe grade of foreign standards, that is, American Standard. A53-f corresponds to Q235 material in China, a53-a corresponds to 10# material in China, and a53-b corresponds to 20# material in China.General purpose galvanized Steel Pipe ASTM A53 gr.B, steel grade: sa53 B, specification: 1 / 4 "- 28", 13.7-711.2mm.

Sa53-b is a general purpose galvanized seamless steel pipe ASTM A53 gr.b, with tensile strength ≥ 415 (MPA) and yield strength ≥ 240 (MPA); Executive standard: ASTM a 53, applicable to the temperature of 350 ° Pressure piping systems, pipes for pipelines and general purpose pipes below C.

What are the characteristics and properties of ASTM A53 galvanized pipe grade B, which is commonly used in the world? What are some necessary tests to do before going out to the United States?

Allowable deviation of weight (mass) and dimension

According to the weight given in table a56.3, or ASTM b36.d The deviation from the specified weight (mass) of the nominal pipe calculated by the relevant formula in 10m standard, which is obtained by multiplying the measured length by the specified weight (mass) per unit length, shall not exceed ± 10%.

For nominal pipe sizes NPs 4 (DN 100) and smaller, the weight (mass) deviation applies to the usual lifting weight (mass) when shipped by the pipe manufacturer. For nominal pipes larger than NPs 4 (DN 100), when weighing a single pipe, the weight (mass) deviation applies to a single pipe.

ASTM A53 galvanized pipe diameter - for nominal pipes up to and including NPs 11 / 2 (DN 40), the diameter at any point shall not be greater than 1 / 64 inch of the value specified in the standard

(0.4m). For nominal pipes larger than or equal to NPs 2 (DN 50), the outer diameter shall not exceed ± 1% of the standard value.

ASTM A53 galvanized pipe thickness - the minimum wall thickness at any place shall not be more than 12.5% thinner than the specified nominal wall thickness. The minimum wall thickness checked shall meet the requirements in the table.

A gauge distance 2in The minimum elongation of (50mm) shall be determined by the following formula:

e=625000(1940)A0. 2/U0. nine

Where:

E = gauge distance 2in (50mm) minimum elongation, rounded to the nearest 0.5%;

A = calculated according to the specified outer diameter of the nominal pipe or the nominal width of the tensile specimen and its specified wall thickness, and rounded to the nearest 0.01in 2 (1mm2) of the cross-sectional area of the tensile specimen and its relation to 0.75in 2 (500mm2), take the smaller of the two.

U = specified minimum tensile strength, psi (MPA).

B for various combinations of tensile specimens of different sizes and specified minimum tensile strength, the required minimum elongation is shown in table X4 1 or table X4 2. According to its applicability.

ASTM A53  galvanized pipe hydrostatic test

1.Each ASTM A53 galvanized pipe shall be subject to hydrostatic test, and there shall be no leakage through the weld or pipe wall.

2.The pipe manufacturer shall prepare each ASTM A53 galvanized pipe according to table x2 2, and each pipe with threaded end with casing joint shall be subject to hydraulic test one by one according to table x2 3. The hydrostatic test can be carried out on the galvanized pipe with smooth end, only the galvanized pipe with threaded end, and the galvanized pipe with threaded end of casing joint; It can be carried out on any kind of galvanized pipe in the form of single ruler or double ruler, which are selected by the pipe manufacturer.

The hydrostatic test pressure given here is the test pressure for inspection, which is not used as the design basis, and has no direct relationship with the working pressure.
