raina paipa API ki te waro maitai
Ko te ngongo paipa API no nga paerewa ANSI Petroleum.Ko te mahi o te paipa raina ko te pupuhi i te hinu, hau, wai mai i te mara ki te parapara.
Ko nga ngongo paipa ko te ngongo korekore me te ngongo paiherea.Ko te whakawhanaketanga o te hangarau pereti rino paipa me te tikanga whakahiato ka whakanuia te whānuitanga pplication o te paipa paiherea.
Rawa i roto i te ngongo maitai diameter nui, paiherea ngongo pipeline he te painga kore.
Nga korero mo te paipa API:
1) Tikanga Tukatuka: ERW paipa rino, LSAW urungi paipa, SSAW paipa maitai , Makao unu, Hot hurihia, DSAW
2) Whakamutunga Mata: Peehia te paninga Varnish
3) Paerewa me te Rauemi: API 5L, API 5CT A, B, X42, X46, X52, X56, X60, X65, X70, X80 5L B, X42, X52 & API 5CT ASTM A106 GR B ASTM A53 GR B
4) Rahi: OD 33.4mm – 914mm mo te paipa maitai tuitui ,323.8mm -1420mm mo te LSAW paipa maitai ,219mm -3120mm
5) Mutunga Whakamutunga: Ko nga pito maamaa, ko nga pito kopikopiko ranei
7) Nga tono: te hinu tawhiti me te kawe hau, te paipa kawe wai
8) Wā takai: Paerewa mōkai moana, paihere tarapēke whānui
API 5L X60 paipa maitai
Ko nga tohu tohu API 5L X60 PSL 1 ka ahu mai i te API Spec 5L Whakatakotoranga mo te Paipa Raina.Ko nga tohu kaha ake ko te tohu X ka whai i te kaha hua iti o te paipa paipa, ka ine ki te kiropauna mo ia inihi tapawha (he ksi whakapoto).Ko te Paipa Raina Paerewa he tohu tohu A me B.
Taupānga: hau, wai me te hinu kawe i roto i rua hinu me te hau māori.
