Cov txheej txheem tsim khoom sib txawv ntawm API 5L thiab A53 kav dej li cas?

Kev xaiv raw khoom
API 5L X52 pipeline: feem ntau lub zog siab qis-alloy steel raug xaiv, thiab purity, suav nrog kev tswj hwm thiab tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau yuav tsum muaj siab kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov raj xa dej raws li kev ua haujlwm hnyav xws li siab. siab thiab kev nyuaj siab.
ASTM A53 cov raj xa dej: cov khoom siv raw feem ntau yog cov pa roj carbon zoo tib yam lossis cov hlau tsis tshua muaj hlau, xws li A53-A sib haum rau hauv tsev 10# steel, A53-B sib raug rau hauv tsev 20# steel, thiab A 53-F sib xws rau cov khoom siv Q235. Nws cov tshuaj muaj pes tsawg leeg thiab kev ua tau zoo yog cov pa, thiab muaj tsawg dua cov kev cai tshwj xeeb rau cov khoom siv raw.
Txoj kev tsim
API 5L X52 Pipeline:
Seamless yeeb nkab: feem ntau ua los ntawm kub dov zeb, rauv coil zeb los yog nruab nrab thiab tuab phaj zeb. Lub steel billet yog thawj rhuab mus rau qhov tsim nyog kub, thiab tom qab ntawd los ntawm perforation, dov thiab lwm yam txheej txheem, lub steel billet yog maj deformed rau hauv ib tug seamless steel yeeb nkab.
Welded steel yeeb nkab: Muaj cov txheej txheem xws li hluav taws xob tiv thaiv vuam (ERW), muab kauv submerged arc vuam (SSAW) thiab ncaj seam submerged arc vuam (LSAW). Cov kav dej loj loj feem ntau yog ua los ntawm kauv submerged arc vuam lossis ncaj seam submerged arc vuam. Lub steel sawb los yog steel phaj yog khoov thiab tsim thiab ces welded los ua cov yeeb nkab.
ASTM A53 Tube:
Kub dov: Cov yeeb nkab dawb paug yog maj mam deformed los ntawm cua sov, perforation, peb-cov menyuam oblique dov, nruam dov thiab lwm yam txheej txheem rau thaum kawg tsim ib tug kub dov seamless steel yeeb nkab.
Kev kos duab txias: Los ntawm lub hauv paus ntawm cov yeeb nkab kub-dov dawb paug, tom qab lub taub hau, annealing, pickling, thiab oiling, ntau yam txias txias txheej txheem yog nqa tawm kom cov yeeb nkab steel ncav cuag qhov loj thiab precision. Cov phab ntsa tuab ntawm cov yeeb nkab steel uas tsim los ntawm cov txheej txheem kos duab txias yog qhov sib txawv dua thiab qhov roughness zoo dua.
Vuam txheej txheem
API 5L X52 yeeb nkab: Rau cov kav hlau welded, cov txheej txheem vuam yuav tsum nruj thiab tsis muaj kev puas tsuaj, xws li 100% X-ray kuaj, yuav tsum tau ua kom ntseeg tau qhov zoo ntawm vuam thiab xyuas kom muaj kev nyab xeeb ntawm cov kav dej hauv qab hnyav. ib puag ncig xws li kev kub siab thiab kub siab. Nyob rau tib lub sijhawm, muaj cov kev cai meej ntawm cov khoom siv vuam, vuam tsis zoo thiab kev tsim nyog ntawm cov vuam vuam.
ASTM A53 pipeline: Cov txheej txheem vuam yuav tsum muaj tsawg. Cov txheej txheem vuam sib txawv tuaj yeem raug xaiv raws li kev siv tshwj xeeb thiab daim ntawv thov scenarios. Feem ntau, nws tsis tas yuav muaj kev ntsuas dav thiab nruj tsis muaj kev puas tsuaj xws li API 5L cov kav dej. Lub hom phiaj ntawm nws qhov kev sim yog ua kom tau raws li cov khoom siv sib xyaw ua ke thiab cov kev cai sib khi.
Kev kho cua sov txheej txheem
API 5L X52 pipeline: Raws li cov qib steel sib txawv thiab siv cov kev cai, kev kho cua sov xws li normalizing, tempering, thiab quenching tej zaum yuav ua tau los txhim kho lub koom haum qauv thiab kev ua tau zoo ntawm steel, thiab txhim kho lub zog, toughness thiab corrosion kuj ntawm cov kav dej.
ASTM A53 pipeline: Nws feem ntau yog xa hauv lub xeev kub dov lossis kev kho mob yooj yim. Qee cov yeeb nkab steel nrog cov kev xav tau tshwj xeeb tuaj yeem raug kho cua sov ntxiv, xws li annealing, tshem tawm kev ntxhov siab thiab txhim kho kev ua haujlwm.
