A106 & A53 steel yeeb nkab

A106 thiab A153 yog cov kav hlau uas feem ntau siv hauv kev lag luam. Ob lub raj zoo sib xws hauv qhov tsos. Txawm li cas los xij, muaj qee qhov sib txawv hauv cov specifications thiab zoo. Kev nkag siab yooj yim ntawm seamless thiab welded yeeb nkab yuav tsum tau yuav cov yeeb nkab zoo. Tham nrog cov neeg muag khoom siv yeeb nkab kom paub meej.

Seamless kav thiab welded kav
A106 thiab A53 cov kav dej yog qhov zoo sib xws hauv cov tshuaj muaj pes tsawg leeg thiab kev tsim khoom. A106 kav yuav tsum seamless. Ntawm qhov tod tes, A53 yuav tsum yog seamless lossis welded. Cov kav dej welded yog ua los ntawm cov hlau phaj koom nrog ntawm cov npoo los ntawm welds. Nyob rau hauv sib piv, seamless raj yog ua los ntawm cylindrical tuav uas nkag mus thaum kub.
A53 tube yog qhov zoo dua rau kev thauj mus los hauv huab cua, ua raws li dej thiab chav txhawb nqa. Nws yog tsuas yog siv rau steel qauv. Hauv qhov sib piv, A106 cov kav dej yog tsim los siv rau qhov kub thiab txias. Nws yog siv rau kev siv hluav taws xob tsim hluav taws xob. Cov kav dej seamless feem ntau siv rau hauv cov cheeb tsam uas muaj qhov kub thiab txias kom tso siab ntxiv rau cov kav dej. Txij li cov kav dej seamless tsis muaj kev pheej hmoo ntawm kev ua tsis tiav, lawv nyiam dua cov kav dej welded.

Qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg
Qhov sib txawv tseem ceeb yog nyob rau hauv cov tshuaj muaj pes tsawg leeg. A106 raj muaj silicon. Ntawm qhov tod tes, A53 raj tsis muaj silicon. Ua tsaug rau lub xub ntiag ntawm silicon, nws txhim kho cov cua sov. Nws yog tsim los rau kev ua haujlwm kub. Yog tias tsis raug silicon, qhov kub thiab txias tuaj yeem ua rau cov yeeb nkab tsis muaj zog. Qhov no, nyob rau hauv lem, yuav tsis muaj zog lub zuj zus deterioration ntawm lub pipeline.
Cov txheej txheem kav dej yog nyob ntawm qhov sib txawv ntawm cov sulfur thiab phosphorus. Cov pob zeb hauv av los ntawm cov ntsiab lus no ntxiv rau kev ua haujlwm ntawm cov kav hlau steel.
