Ubwino Wogwiritsa Ntchito Mapaipi Achitsulo Otchedwa Spiral Submerged Arc Welded Steel Mapaipi Apansi Pansi Pansi

Kufotokozera Kwachidule:

Mukayika mizere yamadzi apansi panthaka, ndikofunikira kusankha mtundu wolondola wa chitoliro kuti muwonetsetse kukhazikika komanso moyo wautali.Chitoliro chodziwika bwino cha mizere yamadzi apansi panthaka ndi spiral welded pipe, yomwe imadziwikanso kuti SSAW steel pipe.

Ubwino wina waukulu wogwiritsa ntchito chitoliro chachitsulo cha spiral submerged arc welded steel pamizere yamadzi apansi panthaka ndi kulimba kwake komanso kulimba kwake.Njira yowotcherera yozungulira imapanga chitoliro cholimba komanso chodalirika chomwe chimatha kupirira kupsinjika ndi kulemera kwa kukwiriridwa pansi.Mphamvu imeneyi ndi yofunika kwambiri kuti tipewe kutayikira komanso kuonetsetsa kuti mipope yamadzi ikugwira ntchito kwa nthawi yaitali.

Kuphatikiza apo, chitoliro chachitsulo cha SSAW chimalimbana ndi dzimbiri, ndikupangitsa kukhala chisankho chabwino kwambiri pazogwiritsa ntchito mobisa pomwe mapaipi amakumana ndi chinyezi komanso zinthu zina zachilengedwe.Kukana kwa dzimbiri kumeneku kumathandiza kukulitsa moyo wa mapaipi anu ndikuchepetsa kufunika kokonza ndi kukonza pafupipafupi.

Ubwino wina wogwiritsa ntchito spiral submerged arc welded steel pipe pamizere yamadzi apansi panthaka ndi kusinthasintha kwake komanso kusinthasintha.Njira yowotcherera yozungulira imatha kupanga mapaipi amitundu yosiyanasiyana, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito mapaipi amadzi osiyanasiyana.Kuonjezera apo, kusinthasintha kwa chitoliro chachitsulo cha SSAW kumapangitsa kuti ikhale yosavuta kukhazikitsa ndikugwira ntchito, makamaka m'madera omwe ali ndi madera ovuta kapena zopinga.

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.

Kuphatikiza pa mphamvu, kulimba, ndi kusinthasintha, chitoliro chachitsulo chozungulira cha arc chimakhala chotsika mtengo poyerekeza ndi mitundu ina ya chitoliro.Njira yowotcherera yozungulira imachepetsa ndalama zopangira, ndikupangitsa kuti ikhale njira yotsika mtengo pamapulojekiti akuluakulu a mapaipi amadzi.Kukhazikika kwanthawi yayitali komanso zofunikira zocheperako za chitoliro chachitsulo cha SSAW zimathandiziranso kupulumutsa ndalama pa moyo wa mzere wamadzi.

Ponseponse, pali zabwino zambiri zogwiritsira ntchito chitoliro chachitsulo chopindika cha arc pamizere yamadzi apansi panthaka, kuphatikiza kulimba, kulimba, kukana dzimbiri, kusinthasintha, komanso kutsika mtengo.Makhalidwewa amapangitsa kukhala njira yodalirika komanso yothandiza pamayendedwe amadzi apansi panthaka, kaya ndi zomangamanga zamatauni, ntchito zamafakitale, kapena zaulimi.

Mwachidule, pankhani yosankha chitoliro chabwino kwambirikwa mizere yamadzi apansi panthaka, spiral submerged arc welded steel pipe ndiye chisankho chabwino kwambiri.Mapangidwe ake opangidwa ndi spiral-welded amapereka mphamvu, kulimba ndi kukana kwa dzimbiri zomwe zimafunikira kuti zigwire ntchito kwa nthawi yayitali, pomwe kusinthasintha kwake komanso kutsika mtengo kumapangitsa kuti ikhale njira yosangalatsa yama projekiti a mapaipi amadzi amitundu yonse.Posankha spiral submerged arc welded steel pipe, mutha kutsimikizira kudalirika ndi moyo wautali wa mizere yanu yamadzi apansi panthaka, kukupatsani mtendere wamalingaliro ndi chidaliro mumadzi anu.
