Ukuqonda Ipayipi le-ASTM A252
Emhlabeni wokwakha nobunjiniyela bomphakathi, ukukhethwa kwempahla kubalulekile ukuze kuqinisekiswe ubuqotho nokuphila isikhathi eside kwesakhiwo. Enye impahla ehlonishwa kakhulu embonini ipayipi le-ASTM A252. Lokhu kucaciswa kubaluleke kakhulu kulabo abasebenza ngamaphrojekthi wokunqwabelanisa, njengoba kuhlanganisa izinqwaba zamapayipi ensimbi angama-cylindrical.
YiniI-ASTM A252?
I-ASTM A252 iyincazelo ejwayelekile echaza izidingo zezinqwaba zamapayipi ensimbi ashiselwe futhi angenamthungo. Lawa mapayipi aklanyelwe ukusetshenziswa njengamalungu ahlala unomphela athwala imithwalo noma njengamagobolondo ezinqwaba zikakhonkolo ezifakwe endaweni. Lokhu kucaciswa kubalulekile ukuze kuqinisekiswe ukuthi amapayipi angakwazi ukumelana nokucindezeleka nemithwalo engase ihlangatshezwe emisebenzini ehlukahlukene, ikakhulukazi ubunjiniyela besisekelo.
IIpayipi le-ASTM A252imininingwane ihlukaniswe yaba amamaki amathathu, ngalinye linezidingo zamandla esivuno ezihlukene. Amandla okukhiqiza aphezulu angafinyelela ku-450MPa, ayenze ifanele izakhiwo ezisindayo njengamabhuloho nezakhiwo eziphakeme.
Idizayini ehlala isikhathi eside: Ingasetshenziswa njengengxenye ethwala umthwalo unomphela noma igobolondo lenqwaba kakhonkolo, imelana nezindawo ezigqwala ngaphansi komhlaba.
Ukuvumelana nezimo: Ububanzi bobubanzi Φ219mm-Φ3500mm, ukujiya kodonga 6-25.4mm, bufanele izimo zejoloji eziyinkimbinkimbi
Amandla ethu ayisisekelo
Ngamakhono okukhiqiza ahamba phambili embonini, umthamo wokukhiqiza waminyaka yonke wamathani angaphezu kuka-500,000, inomugqa owodwa wokukhiqiza wasekhaya wamapayipi amakhulu ensimbi engu-Φ3500mm spiral steel.
Inqubo ye-submerged arc welding (SAW) iyamukelwa, futhi ikhwalithi yokushisela iqinisekiswa ngokuhlolwa okungabhubhisi okufana nama-X-ray namagagasi e-ultrasonic.
Ukulawulwa kwekhwalithi okugcwele
Kusukela ezintweni ezingavuthiwe kuya emikhiqizweni eqediwe, iIpayipi le-Astm A252izinga lisetshenziswa ngokuqinile
Ifakwe i-epoxy anti-corrosion /3PE anti-corrosion treatment, enweba impilo yesevisi ezindaweni zasolwandle ngaphezu kwama-30%.
Inethiwekhi yesevisi yomhlaba wonke
Imikhiqizo ithunyelwa emazweni angaphezu kuka-30 okuhlanganisa iYurophu, iMelika, iNingizimu-mpumalanga ye-Asia kanye neMpumalanga Ephakathi
Sekela ukukhiqizwa okwenziwe ngendlela oyifisayo futhi unikeze izinsiza zokuma okukodwa kusukela ekukhethweni kuya ekuqondisweni kokwakhiwa
Sekukonke, amapayipi e-ASTM A252 ayingxenye ebalulekile emkhakheni wokwakha kanye nobunjiniyela bomphakathi, ahlinzeka ngamandla adingekayo nokuqina kwezicelo ezahlukahlukene. I-Cangzhou Spiral Steel Pipe Group Co., Ltd. ingumkhiqizi ohamba phambili walolu hlobo lwamapayipi, enikeza ububanzi obubanzi nokuqina kwezindonga ukuze kuhlangatshezwane nezidingo ezithile zamakhasimende ethu. Noma ngabe usebenza kumaphrojekthi wokunqwabelanisa noma amanye amaphrojekthi wokwakha, ukuqonda ukubaluleka kwamapayipi e-ASTM A252 nokusebenza nomakhi onokwethenjelwa kuzobaluleka empumelelweni yephrojekthi yakho.
