Welded Stainless Steel Coiled Tubing yog tsim los ntawm duplex stainless hlau, ib yam khoom uas sib txuas cov yam ntxwv ntawm ob qho tib si austenitic thiab ferritic stainless hlau. Piv rau ferritic stainless hlau, nws nthuav tawm superior plasticity thiab toughness, yog dawb los ntawm chav tsev -kub embrittlement, thiab qhia tau zoo heev tiv thaiv intergranular corrosion thiab txhim kho weldability. Tib lub sijhawm, nws khaws qee cov yam ntxwv ntawm ferritic stainless hlau - xws li susceptibility mus rau 475℃embrittlement thiab siab thermal conductivity -thaum tseem muaj cov khoom tshwj xeeb xws li superplasticity.
Duplex stainless hlau 2205 muaj qhov zoo tshaj plaws weldability thiab nthuav tawm tsis tshua muaj kev cuam tshuam rau ob qho tib si txias thiab kub tawg thaum vuam. Feem ntau, ob qho tib si preheating ua ntej vuam los yog tom qab-weld cua sov yuav tsum tau kho.
2507 yog "super duplex" stainless hlau; nws Pitting Resistance Equivalent Number (PREN) nce mus txog 43, tus nqi siab dua li ntawm lwm cov hlau tsis zoo. Txawm li cas los xij, 2507 tsis haum rau qhov chaw pabcuam uas muaj qhov kub thiab txias; Thaum kub hauv qab -50℃lossis siab dua 300 degree, cov khoom siv tawv yuav raug cuam tshuam.
Customized Services

Cov qhab nia xaiv tau
- Rau cov ntawv thov tubing uas tsis tshua muaj siab, tsis tu ncua tsis tu ncua -hu rau hauv dej hiav txwv, thiab tsis muaj H₂S/CO₂-cov kabmob cov kua qaub, 316L lossis 317L stainless hlau tuaj yeem siv. Cov ntaub ntawv no muab cov nqi qis dua thiab tuaj yeem ua lwm txoj hauv kev rau S32304 rau siv nyob rau hauv marine atmospheric aav thiab tsis yog -siab- bearing auxiliary coils.
- Rau ib puag ncig uas muaj qhov siab H₂S / CO₂ concentrations, siab chloride ion ntau ntau, siab kub, thiab hnyav corrosivity, Incoloy 825 yog qhov kev xaiv pom zoo, vim nws cov corrosion kuj tshaj S32750.
Cov chaw siv
ASTM A789 Welded Stainless Steel Coiled Tubing tsim los ntawm TORICH feem ntau yog siv rau cov roj av thiab roj av, suav nrog rau cov tshuaj txhaj tshuaj, cov cuab yeej siv cua, cov kab tswj hydraulic rau subsurface kev nyab xeeb li qub (SCSSVs), thiab hydraulic fais fab system.

FAQ
Q: Lub siab ua haujlwm siab tshaj plaws yog dab tsi?
A: Muab xam raws li ASME B31.3, lub siab rau cov txheej txheem kev khiav hauj lwm ntawm 8 mus rau 50 MPa; rau me me -bore, siab- siab coiled tubing, nws tuaj yeem ncav cuag li ntawm 70 MPa. Qhov ntsuas qhov tseeb yog nyob ntawm cov yeeb nkab txoj kab uas hla, phab ntsa thickness, qib khoom, kev khiav hauj lwm kub, thiab weld zoo.
Q: Puas yog kev kho mob yuav tsum tau ua rau duplex stainless hlau tom qab vuam?
A: Yog. Rau kev siv roj thiab roj av, tom qab-weld tov kev kho cua sov yog qhov yuav tsum tau ua kom rov qab zoo li qub ntawm duplex microstructure, txo qis kev ntxhov siab, tiv thaiv nag lossis daus ntawm cov theem teeb meem, thiab xyuas kom muaj kev tiv thaiv corrosion thiab txhua yam khoom. Peb lub raj yog muab rau hauv kev daws teeb meem - kho mob.
Q: Nyob rau hauv cov cheeb tsam tshwj xeeb ntawm offshore platforms yog cov khoom siv feem ntau?
A: Cov ntawv thov suav nrog cov kav dej hydraulic tswj, cov roj thiab cov roj sib sau ua ke thiab cov tshuab xa hluav taws xob, cov hluav taws xob sib hloov hluav taws xob sib cais, cov dej hauv dej txias thiab cov tshuab desalination, kev tiv thaiv hluav taws, cov dej txhaj tshuaj thiab roj nqa kab, sib sib zog nqus - hiav txwv riser ancillary systems, ballast dej systems, thiab ntau dua.
