Sinikeza izinhlobo ezimbili zezikhombisi-ndlela zokuxubha ukuhlangabezana nezidingo ezahlukene zokuhlobisa nokusebenza:

I-Straight Hairline (Ukuxubha kweLongitudinal):
Okusanhlamvu kuhamba ngobude beshubhu, kudala umphumela wokubuka obushelelezi futhi oqhubekayo. Ilungele ukuhlobisa i-elevator, ama-handrails ezakhiwo, amashubhu wefenisha, nezinye izinhlelo zokusebenza ezisezingeni eliphezulu.

I-Cross Hairline (Ukuxubha Okunqamulayo):
Okusanhlamvu kuzungeza isiyingi seshubhu, kunikeze ukubukeka okuhlukile kokufakwa kwe-end-cap, izingxenye zesakhiwo, nemiklamo yokuhlobisa yangokwezifiso.

I-Cross Hairline	Izinwele Eziqondile

Kwa-SAKY STEEL senza ukuhlola okuqinile kokuqina kumapayipi ensimbi engagqwali ukuze siqinisekise indawo ebushelelezi futhi engaguquki ehlangabezana nezindinganiso zamazwe ngamazwe. Ukuma kwepayipi kuyisici esibalulekile esithinta ukumelana nokugqwala kokugeleza kanye nokusebenza okuphelele ezinhlelweni ezibucayi.

Sisebenzisa amathuluzi anembayo ukuze silinganise amanani amaholo angaphezulu siqinisekisa ukuthi wonke amapayipi ahlangabezana nezidingo zekhasimende ukuze abushelelezi futhi aqedele. Amapayipi ethu alungele ukucubungula ukudla kwamakhemikhali ezimbonini zasolwandle nezakhiwo lapho ikhwalithi yendawo ibalulekile.

Ukuqedwa kwamapayipi ensimbi engagqwali kubalulekile ekusebenzeni nokubukeka. Kwa-SAKY STEEL silawula ngokuqinile ikhwalithi yendawo ngezinqubo zokuhlola ezithuthukile. Isithombe sibonisa ukuqhathanisa okucacile phakathi kwamapayipi angaphezulu amabi anamaphutha abonakalayo namapayipi ethu amahle angaphezulu anobushelelezi futhi afanayo.

Amapayipi ethu ensimbi engagqwali awanawo imihuzuko yemigodi kanye nezimpawu zokushisela eziqinisekisa ukumelana nokugqwala okuhle kakhulu nokwethembeka. Lawa mapayipi asetshenziswa kakhulu kumakhemikhali asolwandle kanye nezakhiwo lapho ubuqotho bomhlaba bubalulekile.

I-SAKY STEEL yenza ukuhlola kwe-PT okungenelayo kumapayipi ensimbi engagqwali nezingxenye njengengxenye yenqubo yethu yokulawula ikhwalithi eqinile. I-PT iyindlela yokuhlola engacekeli phansi esetshenziselwa ukuthola amaphutha angaphezulu njengokuqhekeka kwe-porosity kanye nezinto ezifakiwe ezingabonakali ngeso lenyama.

Abahloli bethu abaqeqeshiwe basebenzisa izinto zokungena zekhwalithi ephezulu nezikanjiniyela ukuze baqinisekise imiphumela enembile nethembekile. Zonke izinqubo ze-PT zilandela izindinganiso zamazwe ngamazwe kanye nokucaciswa kwamakhasimende okuqinisekisa ukuphepha nokusebenza komkhiqizo.

Ukuhlolwa komthungo wepayipi lensimbi engagqwali kuqinisekisa ukuthi wonke amalunga ashiselwe ahlangabezana nekhwalithi edingekayo kanye nezindinganiso zokuphepha. Inqubo yokuhlola igxile ekutholeni amaphutha angaphezulu nangaphakathi njengokuqhekeka, i-porosity, ukufakwa kwe-slag, ukuntuleka kokuhlanganisa, nokungena okungaphelele. Izindlela ezijwayelekile zifaka ukuhlola okubonwayo, ukuhlolwa kokungena kodayi, ukuhlolwa kwe-ultrasonic, nokuhlolwa kwe-radiographic. Indlela ngayinye ikhethwa ngokusekelwe ezintweni zamapayipi, ukushuba kodonga, nezimo zesevisi. Konke ukuhlola kwenziwa ngokuhambisana namazinga omhlaba afana ne-ASME, ASTM, ne-ISO ukuze kuqinisekiswe ubuqotho nokusebenza kwamapayipi ashiselwe.

Isixazululo esisemgqeni wepayipi lensimbi engagqwali inqubo eqhubekayo yokwelapha ukushisa esetshenziswa ngesikhathi sokukhiqiza ukuze kuzuzwe i-austenitic microstructure efanayo kanye nokuthuthukisa ukumelana nokugqwala. Ipayipi lishiselwa kuzinga lokushisa elicacisiwe lokuvala i-annealing, ngokuvamile eliphakathi kuka-1000°C no-1150°C, bese lipholiswa ngokushesha, ngokuvamile lisebenzisa ukucisha amanzi noma ukupholisa umoya ngempoqo. Le nqubo incibilikisa i-carbide precipitates futhi ivimbele ukugqwala kwe-intergranular, iqinisekisa ukuthi izakhiwo zemishini nekhwalithi yendawo ihlangabezana nezindinganiso zamazwe ngamazwe. I-in-line solution annealing ithuthukisa ukusebenza kahle kokukhiqiza kuyilapho kugcinwa ukusebenza komkhiqizo okungaguquki.

Izakhiwo zomshini zomkhiqizo zihloliwe ngokuhambisana ne-ASTM A370 Izindlela Zokuhlola Ezijwayelekile Nezincazelo Zokuhlolwa Komshini Kwemikhiqizo Yensimbi. Yonke imiphumela yokuhlolwa, okuhlanganisa amandla aqinile, amandla esivuno, ubude, nobulukhuni, ithobelana nezidingo ezishiwo futhi ibhalwe njengengxenye yalesi sitifiketi ukuze kuqinisekiswe ukuhambisana namazinga asebenzayo kanye nokucaciswa kwekhasimende.
