Strailed steel kav yog dav siv nyob rau hauv ntau yam lag luam, xws li roj, metallurgy, kev tsim kho, thee mines, ports, machinery thiab lwm yam lag luam. Thaum lub sij hawm kev teeb tsa thiab siv cov kav dej ncaj seam steel, nws muaj cov kev cai nruj heev. Nws yog ib qho tsim nyog los ua kom muaj kev nyab xeeb thiab zoo ntawm cov kav hlau ncaj ncaj raws li qhov tseeb qhov xwm txheej thiab kev ua haujlwm tshwj xeeb. Yog li dab tsi yuav tsum tau them sai sai rau thaum txhim kho thiab siv cov kav hlau ncaj ncaj?
1. Kev tsim kho kev npaj ua ntej kev teeb tsa ntawm cov kav hlau ncaj ncaj
Cov yeeb nkab ditch yuav tsum tau khawb raws li qhov xav tau ntawm cov duab kos. Lub pipeline zoo cib tiav. Ntau hom kev xaws ncaj cov kav hlau uas xav tau rau cov khoom tau tuaj txog. Qhov zoo tsis zoo thiab tshuaj xyuas. Kev npaj ntawm hluav taws xob rauj thiab tshuab polishing tuaj yeem ntsia tau tsuas yog los ntawm kev ua ntau yam kev npaj.
2. Cov txheej txheem kev teeb tsa ntawm cov kav dej ncaj seam steel
Pipeline positioning raws li tus tsim ntawm daim duab, lub prefabricated pipeline bracket raws li nyob rau hauv-site qhov teeb meem, ces noj raws li tus tsim thiab qhov chaw, thiab ces siv lub polishing tshuab zom cov slopes, thiab ces welded. Thaum lub sij hawm vuam, nqa cov hlau mus rau lub welded yeeb nkab chav tsev, dov los ntawm ntau lub yob, thiab maj mam dov nrog hlau los ua ib lub voj voos kheej kheej nrog qhib qhov chaw. 3mm, thiab qhov kawg ntawm qhov chaw nres nkoj vuam yog tiaj tus. Yog hais tias qhov sib txawv loj heev, cov nyhuv uas nyob ib sab yuav raug txo, lub suab nrov tsis txaus, thiab cov welded seam crystals yog indirectly ua ke nrog molten los yog tawg. Yog tias qhov sib txawv me me dhau lawm, cov nyhuv hauv zej zog tau nce ntxiv, qhov vuam cua sov loj dhau, ua rau cov vuam seams puas; los yog lub weld yog squeezed thiab dov tom qab dov, uas tsim ib tug sib sib zog nqus pit, uas cuam tshuam rau qhov zoo ntawm lub weld.
3. Kev tshuaj xyuas zoo ntawm cov kav dej ncaj seam steel
① Lub vuam seam tsis tso cai rau vuam cov kev txhawb nqa, thiab khoov yog zam nrog vuam seams.
② Qhov sib txawv ntawm txoj kab ntsug ntsug ntawm txoj kab ntsug yuav tsum tsawg dua 3 hli, thiab qhov sib txawv ntawm kab rov tav installation yuav tsum tsawg dua 1 hli.
③ Qhov zoo ntawm qhov ncaj seam welded yeeb nkab yuav tsum du, thiab tsis xws li folding, tawg, txheej, thiab vuam tsis raug tso cai. Cov teeb meem me me xws li kev taug kev, khawb, qhov sib txawv ntawm qhov sib txawv, kub hnyiab, thiab nti ntawm qhov chaw ntawm txoj hlua ncaj nraim yuav tsum tsis txhob dhau qhov tuab tsis zoo ntawm phab ntsa.
