Okuvame ukusetshenziswa kakhulu ohlelweni lokumba uwoyela isikhwama sikawoyela se-API esihlinzekwa yi-Hunan Great Steel Pipe Co., Ltd. Sisetshenziswa futhibhora amapayipi, ukubhola ikhola, amapayipi amaphakathi, namapayipi ensimbi okumba anobubanzi obuncane.Umsebenzi oyinhloko we-API ye-oil casing ukusekela udonga lomthombo wamafutha phakathi nayo yonke inqubo yokumba futhi ngemva kokuqedwa, okungaqinisekisa ukusebenza okuvamile kwawo wonke umthombo wamafutha.

Ipayipi lebhokisi likawoyela le-API elihlinzekwa yi-Hunan Great Steel Pipe Co., Ltd luhlobo lwepayipi elihambisa uphethiloli nezinye izinto zokusetshenziswa.Izidingo zobuchwepheshe zepayipi likawoyela le-API elihlinzekwa yi-Hunan Great Steel Pipe Co., Ltd nazo ziqinile.Phakathi kwazo, imfuneko eqinile kakhulu izinga lokushisa, elidinga izinga lokushisa elihambisanayo esigabeni ngasinye sokucubungula.Isibonelo, i-AC1 yensimbi engu-27MnCrV ihambisana nezinga lokushisa elingu-736 degrees Celsius.Izinga lokushisa lokushisa kufanele lilawulwe phakathi kuka-740-810 degrees Celsius ngesikhathi sokucisha izinga lokushisa elingaphansi.Qinisekisa ukuthi izinga lokushisa elingaphansi kwe-temperature quenching lingu-780 degrees, futhi isikhathi sokushisa singaphezu kwemizuzu engu-15;izinga lokushisa lokusaphaza lebhokisi likawoyela we-API elinikezwe i-Hunan Great Steel Pipe Co., Ltd ngemva kokucisha kufanele lilawulwe ku-630 degrees, futhi ukushisa kufanele kulawulwe.Isikhathi kufanele sibe ngaphezu kwemizuzu engama-50.Uma ufuna ukuthuthukisa ukuqina kwekesi likawoyela we-API, izinga lokushisa lokushisisa kufanele lilawulwe phakathi kuka-α + γ, futhi liyadingeka ukuze ucime isikhwama sikawoyela se-API kuyilapho kugcinwa ingxenye ye-ferrite encibilikile.Ngakho-ke, isikhwama sikawoyela se-API siphathwa ngokushisa ngokucisha izinga lokushisa elingaphansi, okungathuthukisa kangcono amandla okubamba uwoyela we-API, futhi kuthuthukise ukuqina komthelela kanye nokumelana nomonakalo we-API kawoyela we-oyela.

Ukulawulwa okuqinile kufanele kwenziwe ngesikhathi sokwelashwa kokushisa kwepayipi lesikhwama sikawoyela se-API elihlinzekwa yi-Hunan Great Steel Pipe Co., Ltd. Kungale ndlela kuphela lapho izinga lepayipi lebhokisi likawoyela le-API elihlinzekwa yi-Hunan Great Steel Pipe Co., Ltd okuqinisekisiwe.Inokuqina okukhulu nokunye ukusebenza ngesikhathi sokusetshenziswa.Isikhwama sikawoyela se-API esihlinzekwa yi-Hunan Great Steel Pipe Co., Ltd samukela indlela yokucubungula yokucisha i-cryogenic ukuze kuncishiswe ushintsho lwengcindezi ngesikhathi sokucisha.Ngokuvamile, izinga lokushisa lokucima i-cryogenic liphansi kunezinga lokushisa elivamile, ngakho-ke akulula ukubangela i-Hunan ngesikhathi sokucisha.Ukuguqulwa kwegobolondo likawoyela we-API okunikezwa i-Great Steel Pipe Co., Ltd. Ukusebenzisa le ndlela yokwelapha akukwazi kuphela ukuqinisekisa ukukhiqizwa okuvamile kodwa futhi kuhlinzeke ngezinto zokusetshenziswa zokucubungula izintambo ezilandelayo.
