Hua Whakataki
Paerewa rauemi:
Ko nga putorino paipa ka whakarōpūhia i runga i nga rawa i mahia ai, tera pea ko te waro maitai, te maitai koranu, etahi atu rawa ranei. Ko nga paerewa rauemi motuhake ka whakawhirinaki ki te tono me te taiao e whakamahia ai te paipa puranga.
Paerewa Hangahanga:
Ko te mahi hanga o te putorino puranga ka hiahia kia tutuki nga paerewa motuhake hei whakarite i te kounga, te pono me te mahi o te paipa. Ko enei paerewa ka whakawhanakehia pea e nga whakahaere penei i te American Society for Testing and Materials (ASTM), te American Petroleum Institute (API), etahi atu roopu paerewa motu, ao ranei.
Paerewa Hoahoa:
Ko nga paipa paipa ka hiahiatia kia tutuki etahi paerewa hoahoa hei whakarite i to raatau hanganga me te kaha ki te kawe. Ko enei paerewa ka whakawhanakehia e nga umanga miihini me te hanga whare, nga tari whakahaere a te kawanatanga ranei.
Nga paerewa hangahanga:
Ka taea e te mahinga hanga o Submerged-Arc Welded Steel Pipes te whai i nga paerewa motuhake kua whakaritea e nga whakahaere penei i te American Petroleum Institute (API), te American Society for Testing and Materials (ASTM), me etahi atu whakahaere paerewa a-motu, ao ranei e whai ake nei: API 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711, EN10217, EN10219
