Ibanga le-ASTM A252

Amabanga e-ASTM A252 ahlukaniswa njengeBanga loku-1 iBanga lesi-2 kanyeIbanga lesi-3.

Inqubo Yokukhiqiza Okubalulekile

Insimbi izokwenziwa ngeyodwa noma ngaphezulu yalezi zinqubo ezilandelayo: indawo evulekile, i-basic-oxygen, noma isithando somlilo sikagesi.

Izinto zokwakha kanye Nokukhiqiza

Izinqwaba zizokwenziwa ngenqubo engenamthungo, ukumelana nogesi okushiselwe, okushiselwe nge-flash, noma inqubo ehlanganisiwe eshiselwe.

Imithungo yezinqwaba zamapayipi ashiselwe kufanele ibe yi-longitudinal, i-helical-butt, noma i-helical-lap.

I-ASTM A252 Chemical Composition

Indlela yokuhlola: ASTM A751.

Insimbi akufanele ibe ngaphezu kuka-0.050 % phosphorus.Lokhu kungenxa yokuthi amazinga aphezulu e-phosphorus angase abangele insimbi ukuba ibe brittle emazingeni okushisa aphansi, inciphise ukuqina kwento.

Ukucaciswa kwe-ASTM A252 kunezidingo ezilinganiselwe zokwakheka kwamakhemikhali: lokhu kungenxa yokuthi i-ASTM A252 isebenza ngokuyinhloko ezinhlelweni zesakhiwo, ikakhulukazi njengezinto ezithwala umthwalo, lapho izakhiwo ezingokomzimba (njengamandla esivuno, amandla aqinile, nobude) zibaluleke kakhulu kunokwakheka kwamakhemikhali. .Lezi zakhiwo ezibonakalayo zingafinyelelwa ngokukhiqiza okufanele kanye nezinqubo zokwelashwa ngokushisa ngaphandle kokulawula okuqinile kokwakheka kwamakhemikhali ngaphandle kwe-phosphorus.

Izidingo ze-ASTM A252 Tensile

Indlela yokuhlola: ASTM A370.

I-Hydrostatic Pressure Test

Isizathu sokuthi i-ASTM A52 ingacacisi ukuhlolwa kwe-hydraulic kungenxa yezimpawu zohlelo lokusebenza kanye nezidingo zokuklama kwalawa mapayipi.

Ngezinqwaba zamapayipi ensimbi ekucacisweni kwe-ASTM A252, inhloso eyinhloko yokuklama iwukumelana nemithwalo ye-axial, hhayi izingcindezi zangaphakathi.Lokhu kuphambene namapayipi okuthuthwa koketshezi noma amagesi, njengalawo angaphansi kokucaciswa kwe-API 5L, okumele ahlolwe ngokuqondile ingcindezi yangaphakathi ukuze kuqinisekiswe ukucinana kwawo namandla.

I-Dimensional Tolerances

Ukubekezelelana kwe-Dimensional
Uhlu	hlunga	ububanzi
Isisindo	Isisindo Sethiyori	95%-125%
Ububanzi	I-Diameter Yangaphandle Ecacisiwe	±1%
Ubukhulu	ukujiya kodonga olucacisiwe	iminithi 87.5%
Ubude	Ubude obubodwa obungahleliwe	16 kuya ku-25 ft [4.88 kuya ku-7.62 m]
	Ubude obuphindwe kabili obungahleliwe	ngaphezu kwamamitha angu-7.62 nesilinganiso esincane esingu-35 ft [10.67 m]
	Ubude obufanayo	ubude njengoba kucacisiwe ngokuhluka okuvumelekile okungu-±1 in.
Beveled	Izinqwaba zamapayipi zizohlinzekwa ngeziphetho ezingenalutho: Lapho iziphetho ziqokwa njenge-beveled	30°-35°

Izinto zikagesi

Izicelo ze-ASTM A252 zeBanga loku-1

Amaphrojekthi alayishwe kancane ezimweni zenhlabathi ezijwayelekile, njengezisekelo zezakhiwo ezincane noma izakhiwo.

Izisekelo zezakhiwo zesikhashana njengezisekelo zokwakha noma amabhuloho esikhashana.

Amaphrojekthi okulungisa imvelo ezimeni ezinhle zenhlabathi lapho kungadingeki ukucindezeleka ngokweqile.

Izicelo ze-ASTM A252 zeBanga lesi-2:

Amaphrojekthi wobunjiniyela anezidingo zokulayisha ezimaphakathi, okuhlanganisa izisekelo zezakhiwo ezinezitezi eziningi noma izinsiza.

Amabhuloho, izinsika, namaphrojekthi asogwini ezindaweni eziqinile zenhlabathi.

Sebenzisa ezimeni ezinezinga elithile lengozi yokugqwala kwamakhemikhali noma ukuguguleka.

Izicelo ze-ASTM A252 zeBanga lesi-3:

Amaphrojekthi abalulekile ngaphansi kwezimo zenhlabathi ezilayishwe kakhulu, eziyinkimbinkimbi njengamabhuloho amakhulu, izakhiwo eziphakeme, kanye nezakhiwo ezinkulu zezimboni.

Izindawo ezinobungozi obukhulu, njengezakhiwo ezingaphansi kokuguguleka okukhulu, ukugqwala kwamakhemikhali, noma izimo zezulu ezimbi kakhulu.

Amaphrojekthi amakhulu asogwini, njengezisekelo zamajethi ajulile, ama-breakwaters amakhulu, nezinkundla zikawoyela negesi.
