Isici Nokuphatha
Isici
Ukungapheleli kobuso okungena ngaphezu kuka-12% wogqinsi oluvamile lodonga noma okudlula ubukhulu obuncane bodonga kuzobhekwa njengamaphutha,
futhi ukonakala okubonwayo okutholakala kujule ngaphezu kuka-5% kunokuqina kodonga okuvame ukubizwa ngokuthi ama-scabs, ama-seams, ama-laps, izinyembezi, noma izingcezu.
Ukuphatha Isici
Amaphutha angase aqedwe ngokugaya, inqobo nje uma ukujiya kodonga olusele kungaphakathi kwemikhawulo ethile futhi kugcinwa indawo ebushelelezi egobile.
Izigaba zamapayipi aqukethe amaphutha zinganqunywa ngaphakathi kwemingcele yemfuneko yobude.
Ukumaka kwe-ASTM A333
Igama lomkhiqizi noma umkhiqizo, inombolo ecacisiwe (unyaka wokukhishwa awudingeki), kanye nebanga kufanele kukhonjwe ngokucacile.
Kufanele futhi ifake izinga lokushisa lapho ukuhlolwa komthelela kwenziwa khona ngemva kokusebenza okushisayo, ukudweba okubandayo, okungenamthungo noma okushiselwe, inombolo yohlelo, nezinhlamvu "LT".
Ukumaka kuyoqala cishe ngamasentimitha angu-300.
Epayipini elingaphansi kwe-NPS 2 kanye nepayipi elingaphansi kwemitha elilodwa ubude, ulwazi oludingekayo lungase luphawulwe ilebula kunqwaba noma ebhokisini ipayipi elihanjiswa ngalo.
