Waro iti putorino porohita paiherea porohita pango rino tui kore waro paipa maitai
Whakaahuatanga
He paipa porowhita maitai ngawari Ko te putorino maitai he kore-kokotahi te maitai waro iti.Ko te tikanga hangarau hanga paipa ko te ERW kua paiherea ki te tui roa.
Ka taea e nga paerewa hua te whakatutuki i te ASTM A500, ASTM A53, ASTM A795, BS1387, BS EN10255, EN 10219, BS 1139, BS 39. Ko te putorino maitai te maitai o te putorino porohita porohita he kore-kokotahi waro iti.Ko te tikanga hangarau hanga paipa ko te ERW kua paiherea ki te tui roa.Ka taea e nga paerewa hua te whai ki te ASTM A500, ASTM A53, ASTM A795, BS1387, BS EN10255, EN 10219, BS 1139, BS 39.
Te rino me nga pito tuwhera me te waahanga whiti whiti he nui ake te roa i te paenga.
Ko nga whakaritenga paipa rino e tohuhia ana e nga rahi o waho (hei tauira, te diameter o waho, te roa taha ranei) me te diameter o roto me te matotoru pakitara.Ko nga rahi mai i nga kapi iti rawa ki nga ngongo porowhita nui tae atu ki etahi mita te whanui.
Nga Whakamahinga Matua
Ka taea te whakamahi paipa maitai porowhita ki te paipa, nga taputapu waiariki, te umanga miihini, te keri whenua hinu, te ipu, te umanga matū me nga kaupapa motuhake.
