Q1: He aha ka ʻokoʻa koʻikoʻi ma waena o ka paipu i uhi ʻia i ka metallurgical a me ka paipu i hoʻopaʻa ʻia i ka mechanical?

A: Hilinaʻi ka paipu i hoʻopaʻa ʻia me ka mīkini i ke kūpono o ka hoʻopilikia ʻana e paʻa i ka liner - ma lalo o ke kaʻapuni wela a me nā pulsations kaomi, hiki i ka liner ke ʻāwili, hiolo a hoʻokaʻawale paha. Hoʻokumu ka paipu i hoʻopaʻa ʻia me ka metallurgically i kahi papa interdiffusion ma ka interface (ikaika shear >300 MPa). ʻAʻohe pilikia o ka delamination liner, e koi ai no ka lawelawe cyclic wai hohonu, hydrogen a me ke kiʻekiʻe-mahana.

Q2: Hiki iā Womic Steel ke ʻōlelo aku i kahi uhi CRA kikoʻī no kaʻu lawelawe ʻino?
A: ʻAe. Loiloi kā mākou hui ʻenekinia i kāu ʻano wai (H₂S, CO₂, Cl⁻, pH, nā waikawa organik), ka mahana hana a me ke kaomi - a laila paipai i ka CRA kūpono loa mai 316L → duplex → nickel alloys. No nā papahana hydrogen hoʻohui mākou i ka hydrogen embrittlement screening hou aʻe.

Q3: He aha ka manawa hoʻouna maʻamau no ka paipu i uhi ʻia me ka hōʻoia API 5LD?
A: No ka hōʻoia ʻana o ka ʻatikala mua a me ka hana hoʻāʻo ʻana o ka pūʻulu ma kahi o 6-8 mau mahina (me ka ʻae ʻana i ke ʻano a me ka hoʻāʻo ʻana i nā mea hōʻike). No nā kauoha hana hou maʻamau: 60 120 mau lā ma muli o OD, nā mea CRA a me nā koi nānā ʻaoʻao ʻekolu.

Q4: Pehea e hōʻoia ai ʻo Womic Steel i ke kūpaʻa ʻana o ka girth weld i ka pala ma nā hui kahua?
A: Hoʻopili mākou i ka uhi ʻili CRA hale hana (buttering) ma nā bevels paipu ʻelua a me kahi hoʻololi mīkini. Pale kēia i ka hoʻoheheʻe ʻia o ka CRA e ke kila kākoʻo i ka wā o ka wili ʻana ma ke kahua. Hoʻomaʻamaʻa ʻia ke kaʻina hana wili no nā hui girth me ka metala hoʻopihapiha Alloy 625 / 825 e mālama i ka hana corrosion e like me ke kino paipu.

Q5: Pehea ka nui o ka mālama kālā hiki i ka paipu bimetal clad ke hāʻawi i hoʻohālikelike ʻia me ka paipu CRA paʻa?
A: Ma muli o nā haʻawina hihia, ʻo kahi paipu i hoʻopili pono ʻia me ka metallurgically i hoʻolālā pono ʻia e mālama i ka 30-50% o ke kumukūʻai waiwai holoʻokoʻa i hoʻohālikelike ʻia me ka nickel alloy paʻa a i ʻole ka paipu alloy kiʻekiʻe o ka helu kaomi like. Hoʻonui ka mālama kālā i ka piʻi ʻana o ke anawaena a me ka mānoanoa o ka paia.

Q6: He kūpono anei ka paipu i hoʻopaʻa ʻia no ka lawelawe ʻawaʻawa (H₂S) a ua ʻae ʻia e NACE?
A: ʻAe. Hiki ke hoʻolako ʻia ka uhi CRA (e laʻa me 625, 825, 2205, 316L) i hui pū ʻia me ke kila kākoʻo kūpono (e laʻa me X65MS, X52NS) e kūlike piha me NACE MR0175 / ISO 15156 a me API 5L Annex H. Hiki ke hana ʻia a hoʻopaʻa ʻia ka hoʻāʻo ʻana o ka paʻakikī, SSC a me HIC.

10. E noi i kahi ʻōlelo kūʻai

Hāʻawi ʻo Womic Steel i nā hoʻonā paipu metallurgical bimetal i hana kūikawā ʻia - e hoʻohana ana i ka ikaika o ke kila kalapona a me ke kūpaʻa ʻana i ka pala o CRA.
