1. Txheej txheem cej luam ntawm cov khoom - Bimetal Metallurgical Clad Pipe yog dab tsi?

Bimetal metallurgical clad yeeb nkab (tseem hu ua CRA clad yeeb nkab, corrosion resistant alloy metallurgically bonded yeeb nkab) yog ib qho kev ua tau zoo composite raj tsim los ntawm cov txheej txheem siab heev metallurgical bonding uas txuas mus tas li ib qho corrosion resistant alloy (CRA) sab hauv txheej rau ib qho siab zog carbon steel lossis qis alloy steel txheej sab nraud ntawm qib atomic. Cov qauv ib txwm muaj yog "CRA sab hauv cladding + high-strength steel sab nraud backing".

Qhov kev tsim "kev tiv taus xeb sab hauv + lub zog sab nraud" no daws qhov teeb meem tseem ceeb ntawm kev tsim kho: yuav ua li cas thiaj thauj tau cov kua dej hnyav (H₂S siab, CO₂ siab, chlorides siab) nyob rau hauv qhov siab thiab dej tob yam tsis siv cov kav dej kim kim.

Cov thev naus laus zis no tau pib ua thawj coj hauv Suav teb xyoo 2004 los ntawm kev koom tes ntawm Xinxing Ductile Iron Pipe, Panzhihua Steel thiab University of Science and Technology Beijing, nrog rau kev tshawb pom tom qab los ntawm CNPC BSS, Ansteel Group, thiab Baoshi Pipe Industry. Cov kev txhim kho no ua rau muaj kev tsim cov kav dej sib txuas ua ke rau cov roj thiab roj av tob, cov chaw roj av qaub, kev xa hydrogen, thiab cov haujlwm CCUS.

Womic Steel, tsim los ntawm cov thev naus laus zis yeeb nkab clad uas tau lees paub thoob ntiaj teb no, sib xyaw ua ke cov tshuab nqus tsev kub dov, centrifugal casting + hot extrusion, thiab cov txheej txheem vuam siab heev uas tswj cov hlau sib txawv ntawm cov hlau nickel thiab cov yeeb nkab hlau. Peb muab cov yeeb nkab clad los ntawm 60mm txog 1800mm OD nrog cov qauv phab ntsa tuab uas yoog tau, nruj me ntsis ua raws li cov qauv thoob ntiaj teb uas xav tau tshaj plaws.

9. Cov Lus Nug Feem Ntau (FAQ)

Q1: Qhov txawv tseem ceeb ntawm cov yeeb nkab hlau thiab cov yeeb nkab uas muaj kab sib dhos yog dab tsi?

A: Cov yeeb nkab uas muaj txheej txheem siv tshuab ua rau lub liner haum rau kev tuav - nyob rau hauv kev hloov pauv thermal thiab kev nias siab, lub liner tuaj yeem ntswj, tawg lossis sib cais. Cov yeeb nkab uas sib txuas ua ke ua ib txheej interdiffusion ntawm qhov sib tshuam (shear strength >300 MPa). Tsis muaj kev pheej hmoo ntawm lub liner delamination, ua rau nws yuav tsum tau ua haujlwm hauv dej tob, hydrogen thiab kev pabcuam cyclic kub siab.

Q2: Puas yog Womic Steel pom zoo kom siv CRA cladding tshwj xeeb rau kuv qhov kev pabcuam corrosive?
A: Yog. Peb pab neeg engineering soj ntsuam koj cov kua dej sib xyaw (H₂S, CO₂, Cl⁻, pH, organic acids), qhov kub thiab txias ua haujlwm - tom qab ntawd pom zoo kom siv CRA pheej yig tshaj plaws los ntawm 316L → duplex → nickel alloys. Rau cov haujlwm hydrogen peb ntxiv cov tshuaj hydrogen embrittlement ntxiv.

Q3: Lub sijhawm xa khoom rau API 5LD daim ntawv pov thawj clad yeeb nkab yog dab tsi?
A: Rau daim ntawv pov thawj thawj zaug thiab kev sim ua ntau yam li 6-8 lub hlis (suav nrog kev pom zoo hom thiab kev sim ua tim khawv). Rau cov lus txib rov ua dua: 60 120 hnub nyob ntawm OD, CRA cov khoom siv thiab cov kev cai tshuaj xyuas thib peb.

Q4: Womic Steel ua li cas thiaj li ua kom cov hlau tsis xeb ntawm qhov sib txuas ntawm cov pob qij txha?
A: Peb siv lub Hoobkas CRA strip cladding (buttering) rau ob lub yeeb nkab bevels ntxiv rau kev hloov pauv machined. Qhov no tiv thaiv kev dilution ntawm CRA los ntawm cov hlau thaub qab thaum lub sijhawm vuam teb. Cov txheej txheem vuam rau cov pob qij txha girth yog tsim nyog nrog Alloy 625/825 filler hlau kom tswj tau kev ua haujlwm corrosion sib npaug rau lub cev yeeb nkab.

Q5: Cov yeeb nkab bimetal clad txuag tau npaum li cas piv rau cov yeeb nkab CRA khoom?
A: Raws li cov ntaub ntawv tshawb fawb, cov yeeb nkab uas tsim los ntawm cov hlau uas tau sib txuas zoo txuag tau 30-50% ntawm tag nrho cov nqi khoom siv piv rau cov yeeb nkab nickel alloy lossis cov yeeb nkab high-alloy uas muaj tib qib siab. Kev txuag tau nce ntxiv raws li txoj kab uas hla thiab phab ntsa tuab nce ntxiv.

Q6: Cov yeeb nkab clad puas haum rau kev pabcuam qaub (H₂S) thiab tau pom zoo rau NACE?
A: Yog. Lub CRA cladding (piv txwv li 625, 825, 2205, 316L) ua ke nrog ib tug tsim nyog backing steel (piv txwv li X65MS, X52NS) yuav muab tag nrho raws li NACE MR0175 / ISO 15156 thiab API 5L Annex H. Hardness, SSC thiab HIC kev xeem yuav ua tau thiab sau tseg.
