Raws li ib qho tseem ceeb ntawm kev thauj mus los kav, seamless steel kav yog dav siv nyob rau hauv roj av, natural gas, chemical kev lag luam, hluav taws xob fais fab thiab lwm yam lag luam.Thaum siv, lawv yuav tsum tau soj ntsuam nruj me ntsis kom ntseeg tau qhov zoo thiab kev nyab xeeb ntawm cov kav dej.Kab lus no yuav qhia txog kev sim seamless steel yeeb nkab los ntawm ob yam: kev sim cov khoom thiab cov txheej txheem.

Cov khoom kuaj muaj xws li cov duab, qhov loj, qhov zoo, cov tshuaj muaj pes tsawg leeg, tensile, cuam tshuam, flattening, flaring, dabtsi yog khoov, hydraulic siab, galvanized txheej, thiab lwm yam.
Kev kuaj xyuas txoj kev
1. Tensile xeem
2. Kev sim cuam tshuam
3. Kev ntsuam xyuas flattening
4. Kev ntsuas kev nthuav dav
5. Kev sim khoov
6. Hydraulic xeem
7. Galvanized txheej tshuaj xyuas
8. Qhov zoo ntawm qhov chaw yuav tsum tsis txhob muaj cov kab nrib pleb, folds, caws pliav, txiav thiab delamination ntawm sab hauv thiab sab nrauv ntawm cov yeeb nkab steel.
Tsis tas li ntawd, kev tshuaj xyuas yuav ua raws li cov neeg siv khoom xav tau, xws liGB/T 5310-2017seamless steel kav rauhigh-pressure boilers.
Cov tshuaj muaj pes tsawg leeg: Cov hlau feem ntau muaj cov ntsiab lus xws li chromium, molybdenum, cobalt, titanium, thiab txhuas, uas tuaj yeem txhim kho cov cua sov thiab tiv thaiv corrosion ntawm hlau.
Mechanical zog: Yield zog ≥ 415MPa, tensile zog ≥ 520MPa, elongation ≥ 20%.
Kev tshuaj xyuas qhov tshwm sim: Tsis muaj qhov pom tseeb tsis xws luag, wrinkles, folds, tawg, khawb lossis lwm yam tsis zoo ntawm qhov chaw.
Kev kuaj tsis muaj kev puas tsuaj: Siv ultrasonic, hluav taws xob thiab lwm txoj hauv kev los kuaj cov kav hlau kom ntseeg tau tias cov kav dej hauv seamless steel tsis muaj qhov tsis zoo.
