Ko te paipa raina whakakikorua e tohu ana ki nga paipa e whakamahia ana i roto i nga paipa mo te kawe wai (penei i te hinu me te hau) kua pania ki nga rawa whakamarumaru. Ka whakamahia te paninga ki waho, o roto ranei o te putorino hei whakarei ake i tona mauroa, te aukati ki te waikura, me te mahi katoa.

Ka taea te tono paipa me te paninga ko te OCTG(casing me te ngongo), te paipa raina tuitui, te paipa ERW, te paipa LSAW, te paipa SSAW, me etahi atu paipa tuitui, paiherea ranei me nga taputapu paipa i roto i nga umanga rereke.

Nga waahanga matua o te paninga i runga i nga paipa

Fusion-Bonded Epoxy (FBE): He paninga rongonui tenei mo nga paipa raina. Ko te FBE he tino pai te aukati i te waikura, ka whakamahia ma te whakamahana i te putorino katahi ka pania he paura maroke ka rewa ka hanga he paparanga whakamarumaru ina whakamatao.

Polyethylene-3LPE (3LPE) Ranei Polypropylene (3LPP): E toru nga paparanga o tenei punaha whakakikorua—he paparanga o roto o te epoxy hono-honohono, he paparanga o waenga o te whakapiri, me tetahi paparanga o waho o te polyethylene (3LPE) polypropylene ranei (3LPP). He pai te whakamarumaru o te waikura me te aukati miihini mo nga paipa rino e whakamahia ana.

Polyethylene Papa-toru (3LPE)

Whakakikorua Taumaha Raima (CWC): I etahi tono, ka pania pea nga paipa ki te paparanga raima hei taapiri i te taumaha me te pumau ki te paipa i runga i te takere moana. He mea noa tenei i roto i nga whakaurunga paipa ki uta.

Taurangi Kounga o te paninga o waho o nga paipa maitai

Taurangi Kounga o te paninga o waho o nga paipa maitai

Ko te tukanga taketake ki te tono paninga i runga i nga putorino maitai he penei i raro nei:

Paparanga o raro → rehu → paura epoxy

Paparanga waenganui → paninga tangohanga → whakapiri

Paparanga o waho → paninga Extrusion → PE/PP

Hei whakaoti i te tukanga i runga ake nei, ko nga taputapu e hiahiatia ana:

Te Rua Paura

Tukatuka-mua → Te rehu paura → Te rongoa → Te tirotiro → Te hua kua oti

Taputapu Tangohanga Kirihou

Tae atu ki nga kaitahuri kirihou, ki nga kai marua, ki nga whakamaroke kirihou, ki nga kaitahuri auau, ki nga rūnanga whakahaere pāmahana, me etahi atu taputapu tautoko.
