Carbon steel tubesyog ua los ntawm steel ingots los yog cov khoom puag ncig steel los ntawm perforation rau hauv capillary hlab, thiab ces ua los ntawm kub dov, txias dov los yog txias txias. Cov pa roj carbon steel raj ua lub luag haujlwm tseem ceeb hauv kuv lub teb chaws cov yeeb nkab steel kev lag luam. Carbon steel hlab tuaj raws li koj qhov nruab nrab thiab kev ua haujlwm. Tsis muaj leej twg tuaj yeem lav tias lawv tuaj yeem siv tau kaum xyoo lossis pes tsawg xyoo. Yog tias cov khoom tsis raug xaiv kom raug, txawm tias cov hlau zoo tshaj plaws yuav raug corroded hauv 3 lub hlis.

Kev siv cov pa roj carbon steel raj muaj ntau yam ua rau ib puag ncig uas lawv siv. Yog tias lawv siv sab nraum zoov yam tsis muaj cov tshuaj tiv thaiv corrosion, lawv yuav perforate sai sai, tab sis yog tias lawv siv sab hauv tsev thiab coated nrog cov txheej tiv thaiv xws li epoxy resin, ces nws tuaj yeem siv tau ntev.

Lub neej kev pab cuam ntawm cov pa roj carbon steel raj muaj feem xyuam rau qib ntawm corrosion ntawm steel kav siv. Cov yeeb nkab steel muaj kev tiv thaiv sab hauv thiab sab nraud corrosion. Internal corrosion yog cuam tshuam rau qib ntawm corrosion ntawm cov yeeb nkab steel los ntawm kev thauj nruab nrab, thiab sab nraud corrosion yog cuam tshuam rau qib ntawm kev tiv thaiv corrosion ntawm ib puag ncig ib puag ncig uas cov yeeb nkab steel nyob thiab kev saib xyuas zoo.

Kev pab lub neej ntawmstainless hlau kavyog qhov ntev tshaj plaws ntawm tag nrho cov kav dej. Lub neej kev pab cuam ntawm cov kav dej yas yog ntau tshaj 25-30 xyoo, kev pab cuam lub neej ntawm cov yeeb nkab steel yog 15 xyoo, kev pab cuam lub neej ntawm cov kav hlau yog 30-50 xyoo, kev pab cuam lub neej ntawm cov kav dej sib xyaw yog 15-30 xyoo, thiab kev pab cuam lub neej ntawm cov kav hlau stainless tuaj yeem ncav cuag 100 xyoo, tsawg kawg yog 70 xyoo, uas yog ntev npaum li lub neej ntawm lub tsev. Tsis tas li ntawd, cov yeeb nkab stainless hlau yog 100% rov ua dua tshiab thiab yuav tsis muaj lub nra hnyav thiab ua paug rau ib puag ncig.
Lub neej ua haujlwm ntev npaum li cas ntawm galvanized steel yeeb nkab?

Lub neej kev pab cuam ntawm galvanized steel yeeb nkab feem ntau yog 8-12 xyoo, thiab lub neej kev pab cuam nruab nrab yog 10 xyoo, thiab ib puag ncig tuaj yeem txuas ntxiv yog tias ib puag ncig qhuav. Kev pab lub neej ntawmwelded kavfeem ntau qis dua qhov no, thiab nws tuaj yeem khaws cia ntev dua yog tias kev kho corrosion ua tiav zoo, tab sis nyob rau hauv tib lub sijhawm, kev pabcuam lub neej ntawm cov kav dej galvanized yog ntev dua li cov kav dej welded.
