Paipu lole CRA

ʻO ke ʻano o ka pipe aahu:he paipu hao kalapona -paipu hao me ka pa'a hao ku'eku'e (CRA) lahilahi i ho'opa'a 'ia i ka ili o loko ('a'ahu'ia), a i 'ole he paipu CRA 'oko'a i ho'okomo 'ia i loko o ka paipu hao kalapona (laina). ʻO ke kumu ka mālama ʻana i ka pale ʻino CRA ma kahi e hoʻopā ai ka wai, me ka mālama ʻana i ka ikaika a me ke kumu kūʻai o kahi mea lawe hao kalapona{4}}.

Ma ka aila, kinoea, a me ka lawe kemika, ʻaʻole ʻo ka corrosion he pilikia mālama wale ia-e wehewehe ana i ke ola o ka ʻōnaehana holoʻokoʻa. ʻO nā paipu kila kalapona maʻamau, ʻoiai ʻoi aku ka ikaika o ka mīkini, hoʻohaʻahaʻa koke ʻia ma lalo o ke kinoea -ʻawaʻawa a i ʻole ka wai kai. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā paipu paʻa paʻa -alloy (CRA).

No ka hoʻopili ʻana i kēia ʻāpana, ua hoʻomohala nā ʻenekinia i kaCRA aahu a me ka paipu laina, he hoʻonā metallurgical holomua e hoʻohuiikaika, pale ʻino, a me ka maikaʻi -kuaii loko o kahi huahana hoʻokahi.

Nā Koho Mea Pono Paipu Pahu (Base + CRA Layer)

Ma kona kumu, ʻo ka CRA Claded Pipe hepaipu bimetallic, hui pū ʻana i ʻelua metala e lawelawe ana i nā kuleana ʻokoʻa akā hoʻohui:

Papa Hana (Outer Shell):ʻO ke kalapona kiʻekiʻe a i ʻole ke kila huila haʻahaʻa (e laʻa, API 5L X60/X65, ASTM A106, A333) hāʻawi i ka hiki haʻahaʻa mīkini -.

Pale ʻino (Layer i loko):Hana ʻia nā mea hoʻoheheʻe nikel-a i ʻole ʻole e like me 316L, Inconel 625, Alloy 825, a i ʻole Duplex 2205 i mea pale paʻa i ka CO₂, H₂S, a me ka chloride-wai waiwai.

Hoʻokō kēia paʻa metala i ka mea hiki ʻole i ka metala ke hoʻokahi: he paipu e kūpaʻa i ke kaomi nui, ka wela, a me ka hoʻouka ʻino ʻana no nā makahiki he mau makahiki, ʻoiai ma lalo o ke kai a i ʻole nā ​​pā kiʻekiʻe -salinity.

ʻAʻole e like me ke kila kalapona maʻamau, koi nā paipu CRA cald i ka hoʻopaʻa pololei ma waena o ka papa alloy a me ka substrate kila. ʻO nā ʻano hana i hoʻohana ʻia ma muli o nā koi hana a me ka paʻakikī o ka lawelawe:

Hoʻopili ʻia kēlā me kēia kaʻina hanaka hoʻomaʻamaʻa wela, ka hoʻāʻo ultrasonic, a me ka nānā ʻana i ka interfacee hōʻoia i ke kūpaʻa metallurgical a me ka uhi ʻana o CRA.

ʻO nā hui āpau a me nā moʻolelo hana

Hoʻopili paipu ʻaʻahue pili ana i ka pale ʻana i ka papa CRA ma ka ʻāpana weld-no ka mea, ʻo ka hoʻoheheʻe ʻana, ka hoʻokomo wela, a me ka hoʻomākaukau ʻana -hopena e hoʻoholo ai inā mālama ʻia ke kūʻē ʻino ma hope o ka hoʻopaʻa ʻana-in. Hōʻike maʻamau ka poʻe kūʻai i ke ʻano hui (wīwīwīwī / naki -ma ka wili), weld-koina hoʻomākaukau hoʻopau, a me ka nui o ka nānā ʻana i ʻole e pau ka hana ʻana ma waho no ka hana hou.

Ke kākau nei kekahi mau RFQ i kēia mewili paipu pale; ua like nā mana kūpono: mālama i ka ʻike CRA ma ka weld, hoʻohana i nā mea hoʻohana kūpono, a hoʻopaʻa i ke kūlana hope CRA ma ka wahi weld.

• Weld -hoʻomākaukau hope:Wehewehe i ka lapaʻau ʻana i ka bevel + CRA i ʻole e ʻoki ʻia ka CRA me ka nakinaki ʻole.
• Hoʻokomo wela a me ka mana hoʻoheheʻe:E mālama i ka kemika CRA ma ke alo weld i paʻa i mea e pale aku ai i ka weld "nānā maikaʻi, ʻino ma hope".
• Ka nānā 'ana:E koi i ka laulā NDT/PMI ma nā wahi weld inā makemake ka papahana ʻae.

No kahi paipu CRA, "ʻaʻahu" a "line" ʻaʻole ia he mau huaʻōlelo kūʻai kūʻai. ʻO ka koho kūpono e pili ana i ka mea hiki ke hele hewa i ka hana ʻana a i ka hoʻopaʻa ʻana -in (ka ʻike ʻana o ka CRA ma nā weld weld, ka neʻe ʻana o ka liner, ka pono pili), a me nā mea e pono ai ka papahana e hōʻoia i ka loaʻa ʻana. Hoʻohana maʻamau ʻo Octal Pipe i ka papa inoa ma lalo nei e hoʻohālikelike i nā RFQ a e pale aku i nā paʻa - hope ma ka spoolbase.

Koho ʻia nā ʻāpana CRA e like me ka mīkini corrosion a me ka hana kemika. Aia nā hoʻonohonoho maʻamau:

ʻO kēia mau hui e hōʻoia i kēlāka pono mechanical a me ka pale corrosionloa'a 'ia i ka manawa like-me ke kaumaha o ke kumu kū'ai CRA piha.

A Paipu CRAHoʻomaopopo pinepine ʻia ka hopena inā ʻaʻole hiki i ke kila kalapona wale nō ke ʻae i nā wai i hana ʻia ma luna o ke ola hoʻolālā, akā ʻaʻole kūpono ka paipu CRA paʻa piha. ʻO nā mea hoʻoulu maʻamau e pili ana i ka pōʻino CO₂, nā pilikia lawelawe ʻawaʻawa, ka lawelawe ʻana i ka wai chloride kiʻekiʻe, a me nā laina kahe o waho kahi i kaupalena ʻia ai ke komo no ka hoʻoponopono ʻana. I kēia mau hihia, ʻaʻole ʻo "CRA ma nā wahi āpau" ka pahuhopu kūʻai pono, akā he ʻili pulu CRA i hoʻomalu ʻia me ka weldability a me nā hōʻike nānā.

Hoʻokomo ʻia ʻo CRA Clad Pipes ma ka honua holoʻokoʻa ma nā wahi kahi e kū ai ka pilikia corrosion a me ke koi ʻana i ke kūkulu.

• Nā laina kahe wai hohonu a me nā ʻāpana o lalo o ka moanae lawe ana i ka wai multiphase
• CO₂ injection a hoʻonui i nā ʻōnaehana hoʻōla
• ʻO nā mea kanu hoʻomaʻemaʻe wai a me nā mea kanu desalination
• ʻO nā hale hana hoʻomaʻemaʻe a me ka petrochemicalka hoʻoili ʻana i ka media acidic a i ʻole chloride
• ʻOihana mana a me kemikama lalo o ke kiʻekiʻe o ka wela a me ke kaomi

Me ka pono CRA i hōʻoia ʻia ma laloNACE MR0175 / ISO 15156aAPI 5LD, hiki i kēia mau paipu ke hana no nā makahiki 20-30 me ka mālama liʻiliʻi.

No nā mea kūʻai e hoʻohālikelikemea hana paipu lolea he kūponomea lako paipu lole, Hō'ike 'ia ka pono o Octal Pipe ma nā kiko'ī hā'awi e ho'omaka pinepine ai i ka pa'a 'ana o ka papahana: laka mākou i ke ala kūkulu lole/liner ma ka RFQ, ho'omalu weld -hope mākaukau i 'ole e hō'ike a hō'ino paha nā ami kahua i ka papa CRA, a e ho'opa'a pa'a i ka traceability i hiki ke ho'oponopono 'ia ka mea CRA a me ke kalapona -mea lawe hao. ʻO ka mea maʻamau, ʻo ia hoʻi ka hoʻouna ʻia ʻana me nā ID paipu like, ka hōʻailona pae -puʻupuʻu maʻemaʻe, a me kahi pūʻulu palapala e hoʻopili ai i ka paipu kumu a me ka papa CRA i ka papa inoa hoʻopuka like-no laila ʻaʻole e koi ʻia nā hui hana i ka hana ʻike hou-ma mua o ka wili ʻana.

FAQ

 

 

FAQ 1 - He aha ka ho'āʻo ʻae ʻana aʻu e noi ai ma API 5LD CRA i ʻaʻahu ʻia a i ʻole paipu laina?

Ma ka liʻiliʻi loa, pono ʻo API 5LD i kahika nānā ʻana i ka hoʻāʻo hydrostatic ma hope o ka uhi ʻana / lining a me ka mālama wela, a pono e loaʻa i ka ʻōnaehana hoʻāʻohōʻoia i hoʻopaʻa ʻia o ke kaomi a me ka manawa paʻano laila ʻaʻole hiki ke "holo" i kēlā me kēia lōʻihi me ka ʻole o ka hoʻokō ʻana i ka koi hoʻāʻo.

FAQ 2 - he aha ka mana'o o ka paipu lole ma ka RFQ paipu aCRA?

I ke kūʻai ʻana i ka paipu,paipu lolehe paipu kumu hao kalapona -me kaʻānai ʻānai -ʻeleʻele (CRA).i hoʻopaʻa ʻia i ka ʻili o loko (ʻaʻahu ʻia), no laila ʻo CRA ka ili i hoʻomaloʻo ʻia ʻoiai ʻo ka paipu lawe lawe i ka ikaika. Uhi ʻo API 5LD i ka paipu laina kila CRA i ʻaʻahu ʻia (a laina) no ka ʻaila a me nā ʻōnaehana paipu kinoea kūlohelohe.

FAQ 3 - Pehea wau e hoʻohālikelike ai i nā mea hana paipu ʻaʻahu a i ʻole kahi mea hoʻolako paipu ʻaʻahu me ka pau ʻole o nā pōʻai RFQ?

E noi i ʻekolu mau mea ma mua:(1)inā paha ʻo ka ʻōleloʻaʻahu ʻiaa i ʻolelaina lainai ka API 5LD,(2)kamea paipu lole(papa kumu + papa CRA + kumu mānoanoa CRA), a(3)weld Hōʻalo kēia i ka pahele maʻamau "kūʻai like, kūkulu ʻokoʻa" i ka hoʻohālikelike ʻana i nā mea hana paipu lole.

FAQ 4 - He aha kaʻu e wehewehe ai no ka wili paipu ʻaʻahu ma nā hui kahua?

No ka meawili paipu lole, 'o ka mea nui, 'o ia ka ho'omau 'ana i ka pale 'ino CRA ma waena o ke ku'e -in: wehewehe i ka ho'omākaukau hope -weld, ka ho'omalu 'ike CRA ma ka wahi weld, a me ka nānā 'ana i nā hui kahua (no laila 'a'ole pau ka hana no ka hana hou). Inā ʻōlelo kahi RFQwili paipu pale, e mālama iā ia e like me ka mana'o like-akā e ho'omau i ka hua'ōlelo aelikepaipu lole.
