1. Dab tsi yog seamless carbon steel yeeb nkab? Dab tsi yog qhov txawv ntawm nws thiab welded steel yeeb nkab?
Seamless carbon steel yeeb nkab yog cov yeeb nkab steel uas tsim los ntawm kub dov, kos duab txias, los yog txias dov txheej txheem, ua los ntawm cov khoom puag ncig steel tuav los ntawm kev tho. Cov yeeb nkab phab ntsa tsis muaj weld seams. Piv rau welded steel yeeb nkab, seamless yeeb nkab muaj lub zog tag nrho, zoo dua kev ua haujlwm siab, thiab siab dua concentricity, ua rau nws haum rau thauj siab - siab, siab - kub, thiab nplaim taws / tawg tawm. Welded steel yeeb nkab yog tsim los ntawm dov thiab vuam steel strips, ua rau weld seams. Nws yog pheej yig dua, tab sis nws lub siab tsis kam thiab corrosion kuj yog feem ntau tsis muaj zog tshaj seamless yeeb nkab ntawm tib specifications.
2. Nyob rau hauv cov kev lag luam twg yog seamless carbon steel kav tsuas yog siv?
Seamless carbon steel yeeb nkab yog dav siv hauv:
* Roj thiab roj extraction, sib sau ua ke thiab kev thauj mus los, roj refining pipelines
* Fais fab nroj tsuag boilers, chav pipelines, siab - kub thiab siab - siab pipelines
* Kev lag luam tshuaj, cov hlab ntsha siab, cov khoom siv hluav taws xob sib pauv
* Mechanical structures, hydraulic systems, bushings, kev txhawb nqa
* Cov kav dej hauv nroog, cua sov, thiab cov kav dej tiv thaiv hluav taws
* Tsheb, kev tsim kho tshuab, khoom siv mining
* Cov choj, steel qauv, kev tsim kho vaj tse, thiab lwm yam.
3. Cov ntaub ntawv dab tsi ntawm seamless carbon steel yeeb nkab koj tuaj yeem tsim tau? Peb feem ntau tsim:
10 # thiab 20 # siab - zoo carbon structural steel
Q355B, Q355C, thiab Q355D qis- alloy siab- lub zog steel
ASTM A106 Gr.B thiab A53 Gr.B seamless steel kav (US tus qauv)
API 5L Gr.B, X42, X46, thiab X52 pipeline steel
ST37 thiab ST52 seamless steel kav (European tus qauv) rau cov qauv siv. Peb tuaj yeem kho cov ntaub ntawv raws li lub teb chaws, Asmeskas, European, thiab Japanese cov qauv raws li cov neeg siv khoom xav tau.
4. ASTM A106 Qib B yog dab tsi? Dab tsi yog nws qhov tseem ceeb siv?
ASTM A106 Gr.B yog seamless carbon steel yeeb nkab rau siab - kub daim ntaub ntawv, belongs rau qeb ntawm nruab nrab- kub thiab nruab nrab- cov ntaub ntawv siab siab pipeline. Nws muaj cov ntsiab lus ntawm cov pa roj carbon monoxide, cov khoom siv kho tshuab ruaj khov, thiab zoo siab - kub thiab siab ua haujlwm, nrog rau zoo weldability. Nws yog tsuas yog siv nyob rau hauv siab - kub chav, roj kub, thiab txheej txheem pipelines nyob rau hauv fais fab nroj tsuag, roj refineries, thiab tshuaj nroj tsuag, thiab yog ib tug ntawm cov feem ntau siv pipeline cov ntaub ntawv nyob rau hauv thoob ntiaj teb engineering tej yaam num.
5. Dab tsi yog API 5L seamless steel yeeb nkab? Dab tsi yog nws cov ntawv thov tseem ceeb?
API 5L yog lub koom haum American Petroleum tus qauv rau kab yeeb nkab, tsim tshwj xeeb rau cov kav dej xa mus rau roj thiab roj. API 5L seamless kav yuav tsum nruj tensile, cuam tshuam, flattening, hardness, thiab tsis yog -kev kuaj kev puas tsuaj, ua rau lawv haum rau ntev - pipelines, chaw nres tsheb roj, oilfield dej txhaj, thiab roj pipelines- tej yaam num uas tsis tshua muaj kev ruaj ntseg thiab sealing yuav tsum tau.
