Seamless steel raj rau kev kub siab boilers suav nrogGB/5310-2007txheem,ASME SA-106/SA-106M-2015,ASTMA210 (A210M)-2012, nruab nrab carbon steel seamless steel raj rau boilers thiab superheaters,ASME AS - 213 / SA - 213 M, ASTM A335 / A335M ASTM A335 / A335M-2018 Kev Ntsuas.

GB/T5310-2017Feem ntau yog siv los tsim cov kev kub siab thiab siab siab siab chav boiler kav dej thiab lwm yam zoo carbon structural steel, alloy structural steel thiab stainless kub resistant steel seamless steel yeeb nkab. High quality carbon structural steel hlau 20g, 20mg, 25mg. Alloy structural steel hlau 15MOG, 20MOG, 12CrMOg, 15CrMOg, 12Cr2MOG, 12CrMOVG, 12Cr3Movsitib, thiab lwm yam

Cov hlau tsis xeb hlau feem ntau siv 1Cr18Ni9, 1Cr18NillNb

Cov ntaub ntawv tseem ceeb sib xwsGB / T5310txuj: 20G, 20MnG, 25MnG, 16Mn, 15Mog.20MOG, 15CrMo, 15CrMoG, 12CrlMoV, 12Cr1MoVG, Cr5Mo, 10CrMo910 lub ntsiab xeem yuav tsum tau: ntxiv rau kom ntseeg tau cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom, ua flaring test xeem. Tsis tas li ntawd, lub microstructure, grain loj thiab decarburization txheej ntawm cov hlau tiav lawm kuj yuav tsum tau. Kev xa khoom raws li txoj cai: Kev kho cua sov

Thaum seamless steel kav xa mus rau cov neeg siv khoom, tuaj yeem sib txawvkev ntim khoomraws li cov neeg siv khoom sib txawv xav tau. Tsis ntev los no, rau cov khoom peb xa mus rau Nyab Laj, cov neeg siv khoom xaiv kev thauj mus los los txo qhov ntim ntawm cov khoom thiab txuag nqi ntim. Peb kuj muaj PVC packing, baling packing, hlau ncej packing, casing packing thiab hais txog. Koj tuaj yeem tshawb xyuas peb lub vev xaib rau lwm txoj kev ntim khoom. Alloy steel tube, seamless steel rajSA 106 GR.B, cevk55 ua,l80 ua, thiab lwm yam, tuaj yeem txais yuav cov saum toj nopacking txoj kev.
