Kev ceev faj rau vuam installation?
Lub zawj ua lub kaum sab xis yog 30 degree ± 5 degree, thiab blunt ntug yog {2}} mm; Qhov chaw muab hluav taws xob vuam yog tsawg dua los yog sib npaug rau 300mm; interlayer kub ntawm ntau-txheej vuam yog<200℃; the purity of the argon arc welding primer protection gas is ≥99.99%; an insulation shed (>5 degree) yuav tsum tsim rau kev tsim kho lub caij ntuj no. Kev kho mob kub kub kev kho cua sov yuav tsum tau nyob hauv 24 teev tom qab vuam.
Yuav kho cov kev puas tsuaj ntawm cov tshuaj tiv thaiv corrosion corrosion?
Yog thaj chaw puas yog tsawg dua 25cla, kua epoxy yuav tsum tau siv rau kev kho; Cov kev puas tsuaj loj-thaj chaw yuav tsum muaj nplaim taws stripping ntawm txheej qub, sandblasting kom tshem cov xeb rau sa2.5 qib, thiab rov ua txheej. 3PE txheej kho txheej kho kom muaj tshwj xeeb extrusion painting tshuab. Tom qab kho, ntsuas nrog lub hluav taws xob hluav taws xob lim dej (9kv \/ hli).
Cov kev cai tshwj xeeb rau lub caij ntuj no siv?
Cov yeeb nkab steel hlau yuav tsum tau padded nrog cov tshuaj tiv thaiv av; Preheating kub ua ntej vuam vuam yog nce li 20 degree; cov tshuaj tua kab mob (ethylene glycol sib tov) yog siv rau kev sim dej siab; Kev tawm tsam cov saw Skid raug ntsia rau ntawm cov tsheb thauj; Frost saum npoo ntawm cov kav hlau hlau yog tshuaj xyuas ua ntej ua haujlwm thaum sawv ntxov. Nres sab nraum zoov ua haujlwm nyob rau hauv huab cua huab cua (<-20℃).
Cov khoom kuaj xyuas ib txwm?
Ntsuas cov phab ntsa thickness txhua xyoo (ultrasonic tuab cov tshuaj ntsuab), thiab pub hnav tsawg dua lossis sib npaug ntawm cov phab ntsa tsim tuab; Saib Flange ntsia Torque (raws li ASME PCC -1 qauv); Kev khawb thiab tshawb xyuas cov txheej tiv thaiv corrosion ib zaug txhua 5 xyoos; Cov logelines ntse yuav tsum tau tshawb xyuas cov ntaub ntawv tiv thaiv cov ntaub ntawv cathodic (muaj peev xwm khaws cia ntawm {}}}}. 2v).
Cov kev ua yuam kev thiab cov kev daws teeb meem?
Weld Beakage: Kev kho mob ib ntus nrog kev siv siab plugging clamp, hloov yeeb cov dej sib txuas tom qab roj nres; Txhawb Kev Hais Haum: Hydraulic jacking kho + qhob qhov taub; khov ceev deformation: ntxiv cov pob qij txha lossis cov roj ntsha; Sab hauv phab ntsa nplai: Pig Yeeb Nkab Tsev Ntxhua Khaub Ncaws Tu + Kev Ua Tshuaj Lom Zem Kev Lom Zem.
