    • Chitoliro Kuwotcherera Spiral Seam Mapaipi achitsulo

    Kufotokozera Kwachidule:

    Takulandilani pakuyambika kwa chitoliro chamsoko wozungulira chomwe chabweretsedwa kwa inu ndi Cangzhou Spiral Steel Pipe Group Co., Ltd., wopanga wamkulu waku China wamapaipi ozungulira zitsulo ndi zinthu zokutira zitoliro.

    Zolemba Zamalonda

    Ku Cangzhou Spiral Steel Pipe Group Co., Ltd., Yathumapaipi ozungulira ozungulirandi zinthu zapamwamba kwambiri zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani.Mapaipi athu amapangidwa kuti azigwiritsidwa ntchito mosiyanasiyana ndipo amadziwika chifukwa chokhazikika, mphamvu komanso kukana dzimbiri.

    Mpweya ndiye chinthu chofunikira kwambiri muzitsulo komanso maziko osiyanitsa chitsulo ndi chitsulo.Mapaipi athu ozungulira ozungulira amapangidwa kuchokera kuzitsulo zapamwamba kwambiri za kaboni zomwe zimatsimikizira kulimba komanso kulimba kwambiri.Ndi kaboni wapamwamba kwambiri, mapaipi athu ndi oyenerera ntchito zosiyanasiyana zamakampani.

    Kuphatikiza pa kaboni, machubu athu ozungulira amakhala ndi zinthu zina zazikulu monga faifi tambala ndi chromium.Nickel ndi chitsulo cha ferromagnetic chomwe chimawonjezera mphamvu zonse ndi kupukuta kwa chitoliro.Kuphatikiza apo, imalimbana ndi dzimbiri ndikuonetsetsa kuti mapaipi athu azikhala ndi moyo wautali.Chromium, kumbali ina, ndi chinthu chofunikira kwambiri muzitsulo zosapanga dzimbiri ndipo imakhala ndi mphamvu yolimbana ndi dzimbiri.Kuphatikizidwa kwa chromium mu mapaipi athu ozungulira ozungulira kumawonjezera moyo wawo wautali komanso kudalirika.

    Ubwino waukulu wa mapaipi athu ozungulira msoko ndi kapangidwe kake kopanda msoko, komwe kumatheka kudzera muukadaulo wapamwamba wowotcherera.Ukadaulo wathu waukadaulo wowotcherera wa SAWH (Submerged Arc Spiral Welding) umatsimikizira mgwirizano wamphamvu komanso wokhalitsa pakati pa mbale zachitsulo zapaipi.Izi kuwotcherera luso sikuti kumangowonjezera mawotchi katundu chitoliro, komanso amaonetsetsa yosalala pamwamba pamwamba, amene amathandiza kuti bwino otaya zosiyanasiyana zamadzimadzi kapena mpweya.

    Mipope yathu yozungulira yozungulira imagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kuphatikiza mafuta ndi gasi, zoyendera pamadzi, zomanga ndi zomangamanga.Itha kukhazikitsidwa pama projekiti akumtunda ndi kunyanja komanso mumayendedwe amapaipi pazolinga zosiyanasiyana.Ndi kukana kwake kwa dzimbiri komanso kulimba kwamphamvu kwambiri, mapaipi athu ndi chisankho choyamba pakuwotcherera chitoliro m'malo ovuta.

    a.Njira ya deoxidation imayikidwa motere:

    FF: Chitsulo chopha kwathunthu chokhala ndi zinthu zomangira za nayitrogeni mu kuchuluka kokwanira kumanga nayitrogeni yomwe ilipo (mwachitsanzo min. 0,020 % okwana Al kapena 0,015 % sungunuka Al).

    b.Kuchuluka kwa nayitrogeni sikugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al zomwe zili 0,020 % ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati zinthu zina zokwanira za N-binding zilipo.Zinthu zomangiriza za N zidzalembedwa mu Inspection Document.

    Ku Cangzhou Spiral Steel Pipe Group Co., Ltd., timayika patsogolo kukhutitsidwa kwamakasitomala.Gulu lathu lodzipereka la akatswiri limawonetsetsa kuti chitoliro chilichonse cha spiral seam chimadutsa njira zowongolera bwino kuti zikwaniritse miyezo yapadziko lonse lapansi.Kuphatikiza apo, timapereka njira zambiri zokutira zamapaipi, kuphatikiza epoxy, polyethylene ndi matope a simenti, kupititsa patsogolo kukana kwa dzimbiri kwa chitoliro ndikukulitsa moyo wake wautumiki.
