ASTM A53 VS A153 steel

ASTM A53 pipe covers Welded and also smooth, Crno kao i Hot-Dipped pocinkovani nominalna (prosek) zid površinski naftovoda za uvijanje, savijanje, flanging i takođe druge jedinstveni ciljevi i appropriates za zavarivanje. Kontinuirano zavarena naftovoda nije namenjen flanging. Cilj za koji se planira naftovoda trebalo bi navesti na nalogu.

Od svih, Moramo da razlikuje razliku između ASTM A53, kao i ASTM A153. Mnogi galvanizers su upoznati sa A153, Uslov specifikacije za sloj cinka (-Dip) na gvozdenim kao čelik hardver. Treba da uzmete u obzir kada mi čujemo nekoga pitati u vezi A53 koja je potpuno različite uslove. zapravo, Naslovi ASTM A53 kao konvencionalne uslove za naftovod, челик, Crno kao i cokoladnu Hot, Pocinkovane, Zavarene kao i bez problema. Oblast 17 od ASTM A53, pod nazivom pocinkovani lulu, Precizira zahteve za pocinkovani naftovoda kupio ispod ove zahteve. U odeljku zahteva naftovod biti-dip pocinkovani klase cinka pridržavanje specifikacija B6, Kriterijum zahteve za cink, as well as provides needs for weight per unit area of the finishing.

ASTM A53 does not have the demands for the coating, изглед, or adherence of the galvanized layer that exist in ASTM A123, Requirement Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Product. The weight each system area of the covering called for in ASTM A53 is precisely the same as the minimum layer thickness needs of the very same product in ASTM A123. Резултат, ASTM A123 is an extra extensive and extensive spec in relation to the galvanized finishing. It will certainly fulfill the requirements of section 17 of ASTM A53 if a steel pipe is galvanized in accordance to ASTM A123.


1/2″– 12″ some limitations dependent after quality. Sizes up to 26OD are offered on restricted basis.

This spec covers smooth as well as bonded black as well as hot-dipped čelične Pocinkovane cevi in NPS 1/8 da NPS 26 [ДН 6 ово ДН 650] (Napomena 1), comprehensive, with nominal wall thickness (Napomena 2) as given up Table X2.2 as well as Table X2.3. It shall be allowable to provide pipeline having various other dimensions provided that such pipe abide by all various other demands of this specification. When specified by the purchaser, supplemental requirements of an optional nature are supplied and also will use just.

Keep in mind 1The dimensionless designators NPS (nominal pipeline dimension) [ДН (diameter nominal)] have been replaced in this spec for such typical terms as “мали пречник,” “dimension,” kao “small size.

4. 1 Hydrostatic Checking
Hydrostatic assessment examination stress for ordinary end as well as threaded and also coupled pipe are specified. Hydrostatic stress shall be maintained for not less than 5 seconds for all sizes of smooth as well as electric-resistance-weld pipe.

5. Calibration Standards:

Calibration Standards
6. Materials as well as Manufacture

The steel for both smooth and also bonded pipeline will be made by several of the complying with procedures: open-hearth, electric heating system, or basic-oxygen. The weld joint of electric-resistance bonded pipe in Grade B shall be warmth dealt with after welding.


Developed for curling, flexing and flanging, A53 karbonski lulu appropriates for welding. The qualities denote particular chemical and mechanical residential or commercial properties and ought to be kept in mind in option.

Note 2The term small wall density has actually been designated for the purpose of practical classification, existing in name only, as well as is made use of to differentiate it from the actual wall density, which could differ over or under the nominal wall thickness.


The list below types and also qualities of A53 pipeline are covered within this specification:

Kind FFurnace-butt-welded, continual welded Quality A.
Type E- Electric-resistance-welded, Ocene za a i B.
Kind S- Bešavne, Grades An and B.

ASTM A53 pipeline is planned for mechanical as well as pressure applications and also is also appropriate for ordinary usages in vapor, вода, gas and also air lines.

Keep in mind 3See Appendix X1 for interpretations of sorts of pipe.

1.3 Pipe purchased under this specification is planned for mechanical as well as pressure applications as well as is likewise acceptable for common usages in heavy steam, ваздух, gas, and also water lines. It is suitable for welding, as well as suitable for forming operations involving coiling, savijanje, and also flanging, based on the adhering to certifications:

1.3.1 Type F is not intended for flanging.

1.3.2 If Kind S or Type E is needed for close coiling or cold flexing, Grade A is the favored grade; nevertheless, this is not meant to forbid the chilly bending of Quality B pipe.

1.3.3 Type E is provided either nonexpanded or cold expanded at the choice of the maker.

Requirement Requirements for Pipeline, челик, Black and also Hot-Dipped, Pocinkovane, Zavarene kao i bez problema. This requirements covers smooth and welded hot-dipped and also black galvanized steel pipe.
