Chiyambi cha Chitoliro Chopanda Msoko cha ASTM A53

Chitoliro chachitsulo chosasunthika cha ASTM A53imagawidwa m'gulu la A53 Type S ndipo ndi chitoliro chachitsulo chopanda msoko.

Ili ndi magawo awiri, Giredi A ndi Giredi B, ndipo ndi yoyenera kugwiritsidwa ntchito ndi makina ndi mphamvu, komanso kugwiritsidwa ntchito kwambiri pa nthunzi, madzi, gasi, ndi mpweya. Chitoliro chachitsulo ichi ndi chitoliro chachitsulo cha kaboni chomwe chimagwiritsidwa ntchito polumikiza ndi kupanga zinthu kuphatikizapo kulumikiza, kupindika, ndi kulumikizana kwa flange.

Mitundu Yathu Yoperekera Zinthu

Kuyambira pomwe idakhazikitsidwa mu 2014,Chitsulo cha Botopwakhala kampani yotsogola yogulitsa mapaipi achitsulo cha kaboni kumpoto kwa China, yodziwika bwino chifukwa cha ntchito zabwino kwambiri, zinthu zapamwamba, komanso mayankho omveka bwino.

Kampaniyo imapereka mapaipi osiyanasiyana achitsulo cha kaboni ndi zinthu zina zokhudzana nazo, kuphatikizapo mapaipi achitsulo opanda msoko, ERW, LSAW, ndi SSAW, komanso mndandanda wathunthu wa zolumikizira mapaipi ndi ma flange. Zogulitsa zake zapadera zimaphatikizaponso zitsulo zapamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zosowa za mapulojekiti osiyanasiyana a mapaipi.

Njira Yopangira

Mapaipi achitsulo a ASTM A53 akhoza kukhala opanda msoko kapena olumikizidwa.

Njira yopangira yopanda msoko (Mtundu S) ndi kugwiritsa ntchito chitsulo chotentha, ndipo ngati pakufunika, kumaliza kozizira kwa chinthu chotentha kuti chikwaniritse mawonekedwe, miyeso, ndi katundu wofunikira.

Mayeso Opindika

Kwa DN ≤ 50 [NPS ≤ 2], kutalika kokwanira kwa chitoliro kuyenera kupindika kuzizira kudutsa 90° mozungulira mandrel yozungulira, yomwe m'mimba mwake ndi nthawi khumi ndi ziwiri kuposa m'mimba mwake wakunja kwa chitoliro, popanda kupanga ming'alu pagawo lililonse.

Wamphamvu kwambiri kawiri(XXS) chitoliro chodutsa pa DN 32 [NPS 1 1/4] sichiyenera kuyesedwa kupindika.

Mayeso Ophwanyika

Machubu achitsulo opanda msoko safunika kuyesedwa kuti aphwanyidwe.

Ngati pakufunika ndi mgwirizano, kuyesaku kungachitike motsatira ndondomeko yomwe ili mu S1.

Mayeso a Hydrostatic

Mapaipi onse achitsulo opanda msoko ayenera kusunga mphamvu ya madzi popanda kutayikira kwa masekondi osachepera asanu.

Kupanikizika kwa mayeso a mapaipi achitsulo opanda malire kungapezeke mu Table X2.2.

Kupanikizika kwa mayeso a mapaipi achitsulo olumikizidwa ndi olumikizidwa kungapezeke mu Table X2.3.

Mayeso Amagetsi Osawononga

Itha kugwiritsidwa ntchito ngati njira ina m'malo mwa mayeso a hydrostatic.

Kutalika konse kwa chitoliro chilichonse chopanda msoko kuyenera kuyesedwa ndi magetsi mosawononga motsatira malamulo aE213, E309kapenaE570.

Kuwunika kwa ASTM A53 kwa chitoliro chachitsulo chosasunthika (2)

Kuphimba Pamwamba

Muyezo wa ASTM A53 umalongosola zofunikira za momwe mapaipi akuda alili komanso momwe mapaipi achitsulo amaphimbidwa ndi galvanized.

Chitoliro Chakuda

Chitoliro chakuda chimatanthauza momwe chitoliro chachitsulo chilili popanda kukonzedwa pamwamba.

Mapaipi akuda nthawi zambiri amagwiritsidwa ntchito m'malo omwe nthawi yosungira ndi yochepa, malo ouma komanso osawononga, ndipo mtengo nthawi zambiri umakhala wotsika chifukwa palibe chophimba.

Kuphimba kwa Kanasonkhezereka Kotentha

Mapaipi opangidwa ndi galvanized, omwe amadziwikanso kuti mapaipi oyera, nthawi zambiri amagwiritsidwa ntchito m'malo ozizira kapena owononga.

Zinc mu zinc coating ikhoza kukhala mtundu uliwonse wa zinc mu ASTM B6.

Chitoliro chopangidwa ndi galvanized chiyenera kukhala chopanda malo osaphimbidwa, matuza, ma flux deposits, ndi zinyalala zonse. Ziphuphu, ma projection, ma globules, kapena zinc zambiri zomwe zingasokoneze kugwiritsa ntchito kwa chipangizocho siziloledwa.

Zinc yomwe ili mkati mwake si yochepera 0.55 kg/m² [1.8 oz/ft²].

Zophimba Zina

Kuwonjezera pa chitoliro chakuda ndi chophimba cha galvanized, mitundu yodziwika bwino ya chophimba imaphatikizapoutoto, 3LPE, FBE, ndi zina zotero. Mtundu woyenera wokutira ukhoza kusankhidwa malinga ndi zofunikira zenizeni za malo ogwirira ntchito.
