I. Vim li cas Cracked Steel Pipes yuav tsum tsis txhob siv?
1. Cov kab nrib pleb yuav txuas ntxiv mus: Nyob rau hauv lub siab, kev vibration, los yog kub hloov, kev ntxhov siab concentration tshwm sim ntawm qhov tawg, ua rau kev nthuav tawm sai thiab thaum kawg ua rau tawg sai sai.
2. Txo qhov hnyav heev-Cov Peev Xwm Muaj Peev Xwm: Txawm tias zoo li cov kab nrib pleb me me tuaj yeem txo cov yeeb nkab steel load-cov kabmob muaj peev xwm qis dua 30% ntawm tus nqi tsim, deb dua li cov qauv kev nyab xeeb.
3. Irreversible Structural Damage: Cracks sawv cev rau kev puas tsuaj rau cov khoom nws tus kheej thiab tsis tuaj yeem rov qab los rau lawv qhov qub zog thiab sealing kev ua tau zoo los ntawm kev kho yooj yim.
⚠️ Kev Ceeb Toom Tshwj Xeeb: Raws li "Kev Nyab Xeeb Kev Qhia Tshwj Xeeb rau Kev Tsim Kho Scaffolding nrog Couplers" JGJ130, cov yeeb nkab steel uas muaj qhov sib hloov lossis qhov ntev ntawm qhov tob> 0.8mm yuav tsum tau muab pov tseg.
II. Cov txheej txheem kho kom raug tom qab tshawb pom qhov tawg
1. Kev nres tam sim ntawd thiab kev sib cais: txiav tawm qhov ntws ntawm qhov nruab nrab (piv txwv li, dej, roj, roj), depressurize, thiab cais cov seem ntawm cov yeeb nkab tawg kom tiv thaiv qhov kev sib tsoo ntawm qhov nce.
2. Kev soj ntsuam thiab kev pom zoo ntawm tus kws tshaj lij
Magnetic particle soj ntsuam (MT) yog siv los kuaj xyuas qhov chaw thiab ze ntawm - cov kab nrib pleb;
Ultrasonic kuaj (UT) yog siv los txiav txim siab yog tias cov kab nrib pleb nkag mus rau hauv cov yeeb nkab thiab muaj qhov txuas ntxiv sab hauv;
Nws raug nquahu kom siv kev sib xyaw ua ke ntawm MT thiab UT rau kev ntsuas dav.
3. Kev txiav txim siab raws li kev soj ntsuam xyuas
Yuav Tsum Tau Hloov: Cov kab nrib pleb nkag mus rau hauv cov yeeb nkab phab ntsa, ntev dua 50mm, los yog nyob rau hauv siab -cov kev ntxhov siab xws li lub luj tshib / vuam;
Kev Kho Thaum Muaj Xwm Ceev Ib ntus (tsuas yog qis dua-Txoj Tsis Txaus Siab- Cov Txheej Txheem Tseem Ceeb): Txhim kho nrog cov nplaum kho hlau lossis lub tes tsho tshuab, tab sis yuav tsum tau hloov pauv sai li sai tau;
Rework Tso Cai: txwv rau cov kab nrib pleb ntiav; tom qab sib tsoo, rov- yuav tsum tau kuaj xyuas kom paub meej tias qhov tsis muaj qhov seem seem.
III. Yuav ua li cas tiv thaiv rov tshwm sim ntawm cov teeb meem zoo sib xws?
1. Kev tswj qhov chaw: Siv siab -purity billets, tswj kev suav nrog tsawg dua lossis sib npaug li 2;
2. Kev ua kom zoo tshaj plaws: Ua kom cov cua sov tsis sib xws thiab sib txuam dov tsis tau kom tsis txhob muaj kev ntxhov siab;
3. Thaum tshav kub kub kho Specifications: ua kom tempering nyob rau hauv 2 teev tom qab quenching kom tsis txhob ncua kev tawg;
4. Kaw-Loop Factory Inspection: Txhua lub yeeb nkab steel yuav tsum dhau qhov kev tshuaj ntsuam peb zaug nrog rau kev kuaj hydrostatic, UT, thiab MT.
✅ Cov lus pom zoo: Hauv qhov xwm txheej tseem ceeb xws li siab - siab boilers thiab roj thiab roj tsheb thauj mus los, ua ntej cov khoom lag luam nrog API 5CT thiab GB 5310 ntawv pov thawj kom ua raws li cov txheej txheem.
