Chitoliro chachitsulo cha ASTM A53 chopanda msokoimatchedwa A53 Type S ndipo ndi chitoliro chachitsulo chosasokonezeka.
Imagawidwa m'magiredi awiri, Gulu A ndi Gulu B, ndipo ndiyoyenera kugwiritsa ntchito makina ndi kukakamiza, komanso kugwiritsa ntchito nthawi zonse pa nthunzi, madzi, gasi, ndi mpweya.Chitoliro chachitsulo ichi ndi chitoliro cha chitsulo cha carbon chomwe chili choyenera kuwotcherera ndi kupanga ntchito kuphatikizapo kupiringa, kupindika, ndi kugwirizana kwa flange.

Pochita, Ndandanda 40 ndi Ndandanda 80 ndi magulu awiri omwe amagwiritsidwa ntchito kwambiri pakhoma la chitoliro.Kuti mudziwe zambiri, chonde onaniSinthani kalasi ya PDFfayilo yomwe timapereka.
Kuyambira pomwe idakhazikitsidwa mu 2014,Botop Steelwakhala katundu kutsogolera mpweya zitsulo chitoliro ku Northern China, kudziwika ndi utumiki kwambiri, mankhwala apamwamba, ndi mayankho mabuku.
Kampaniyi imapereka mapaipi osiyanasiyana a zitsulo za carbon ndi zinthu zomwe zimagwirizana nazo, kuphatikizapo zopanda msoko, ERW, LSAW, ndi chitoliro chachitsulo cha SSAW, komanso mzere wathunthu wazitsulo ndi flanges.Zopangira zake zapadera zimaphatikizanso ma alloys apamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zofunikira zama projekiti osiyanasiyana a mapaipi.
Mapaipi achitsulo a ASTM A53 amatha kukhala opanda msoko kapena kuwotcherera.
Njira yopangira yopanda msoko (Mtundu wa S) ndi ntchito yotentha yachitsulo ndipo, ngati kuli kofunikira, kutsirizitsa kozizira kwa chinthu chotentha chopangidwa ndi tubular kuti chikwaniritse mawonekedwe ofunikira, miyeso, ndi katundu.
Mu muyezo wa ASTM A53, zofunikira zamagulu amtundu wa S ndiMtundu Emapaipi achitsulo ndi ofanana, pomwe zofunikira zamtundu wamtundu wa F ndizosiyana.

Bend Test
Za DN ≤ 50 [NPS ≤ 2], utali wokwanira wa chitoliro ukhoza kukhala wozizira kwambiri kupyolera mu 90 ° kuzungulira mandrel ya cylindrical, yomwe m'mimba mwake imakhala nthawi khumi ndi ziwiri kuposa yomwe idatchulidwa kunja kwa chitoliro, popanda kupanga ming'alu pa gawo lililonse.
Pawiri-owonjezera-amphamvu(XXS) chitoliro chodutsa DN 32 [NPS 1 1/4] sichiyenera kuyesedwa.
Mayeso a Flattening
Machubu achitsulo opanda msoko safunikira kuyesedwa kwa flattening.
Ngati pakufunika ndi mgwirizano, kuyesako kumatha kuchitidwa molingana ndi ndondomeko ya S1.
Miyezo yonse yamapaipi achitsulo osasunthika iyenera kukhalabe ndi kuchuluka kwa mphamvu yamadzi popanda kutayikira kwa masekondi 5.
Kupanikizika kwa mayeso a mapaipi achitsulo osatha kumapezeka mu Table X2.2.
Makani oyesera a mapaipi achitsulo olumikizidwa ndi ulusi akupezeka mu Table X2.3.
Itha kugwiritsidwa ntchito ngati njira ina yoyeserera ya hydrostatic.

Muyezo wa ASTM A53 umatchula zofunikira pamtundu wa chitoliro chakuda ndi zokutira zamapaipi otentha azitsulo.
Black Pipe
Black chitoliro amatanthauza boma chitoliro zitsulo popanda mankhwala pamwamba.
Mapaipi akuda amagwiritsidwa ntchito m'malo omwe nthawi yosungiramo ndi yochepa, chilengedwe chimakhala chouma komanso chosawononga, ndipo mtengo wake nthawi zambiri umakhala wotsika chifukwa palibe zokutira.
Kupaka kotentha kwa galvanized
Mapaipi opangidwa ndi malata, omwe amadziwikanso kuti mipope yoyera, amagwiritsidwa ntchito nthawi zambiri m'malo achinyezi kapena owononga.
Zinc mu zokutira zinki zitha kukhala giredi iliyonse ya zinki mu ASTM B6.
Chitoliro cha malata chizikhala chopanda madera osakutidwa, matuza, ma depositi otuluka, ndi kuphatikizika kwa zinyalala.Ziphuphu, mawonedwe, ma globules, kapena ma depositi olemera a zinc omwe angasokoneze kagwiritsidwe ntchito ka zinthuzo sizidzaloledwa.
Zinc zili ndi zosachepera 0.55 kg/m² [1.8 oz/ft²].
Zopaka Zina
Kuphatikiza pa chitoliro chakuda ndi zokutira zamagalasi, mitundu yojambulira wamba imaphatikizapoutoto, Mtengo wa 3LPE, FBE, etc. Mtundu woyenera wophimba ukhoza kusankhidwa malinga ndi zofunikira zenizeni za malo ogwirira ntchito.
Kupereka zidziwitso zotsatirazi kupangitsa kuti ntchito yanu yogulira ikhale yabwino komanso yolondola.
