Kuwonetsetsa Kuchita Bwino Ndi Kukhalitsa Kwa Mapaipi Amadzi Akuluakulu Okhala Ndi Mapaipi Otsekemera Ozungulira

Kufotokozera Kwachidule:

Gawo ili la European Standard limatchula zaukadaulo woperekera magawo oziziritsa opangidwa ndi welds, magawo opanda dzenje a mawonekedwe ozungulira, masikweya kapena amakona anayi ndipo amagwira ntchito ku magawo amphako omwe amapangidwa ozizira popanda kutenthedwa pambuyo pake.

Cangzhou Spiral Steel Pipes Group Co., Ltd imapereka gawo lopanda kanthu la mipope yachitsulo yozungulira.

Tsegulani:

Mipope yayikulu yamadzi ndi ngwazi zomwe sizimayimbidwa zomwe zimapereka madzi ofunikira kumadera athu.Maukonde apansi panthaka amenewa amagwira ntchito yofunika kwambiri poonetsetsa kuti madzi akuyenda mosadukiza m’nyumba zathu, m’mabizinesi ndi m’mafakitale.Pamene kufunikira kukukulirakulira, ndikofunikira kugwiritsa ntchito zida zoyenera komanso zolimba pamapaipi awa.Chinthu chimodzi chomwe chikukhudzidwa kwambiri ndi spiral welded pipe.Mu blog iyi, tiwona kufunikira kwa mipope yowotcherera yozungulira pamapaipi akuluakulu operekera madzi ndikukambirana za phindu lawo.

Phunzirani za mapaipi a spiral welded:

Tisanalowe mu ubwino wamipope yozungulira yozungulira, choyamba tiyeni timvetsetse lingaliro la mipope yozungulira yozungulira.Mosiyana ndi mapaipi owotcherera achikhalidwe, mipope yozungulira yozungulira imapangidwa ndi kugudubuza ndi kuwotcherera zitsulo zozungulira mozungulira.Kupanga kwapadera kumeneku kumapereka mphamvu ya chitoliro, ndikupangitsa kuti ikhale yabwino kwa ntchito zapansi panthaka monga mapaipi amadzi.

Ubwino wa mipope yowotcherera yozungulira pamapaipi akuluakulu operekera madzi:

1. Kuchulukitsa mphamvu ndi kulimba:

Ukadaulo wowotcherera wozungulira womwe umagwiritsidwa ntchito m'mapaipiwa umapanga mawonekedwe osalekeza, osasunthika okhala ndi mphamvu zapamwamba komanso kukana kupsinjika kwakukulu mkati ndi kunja.Kuphatikiza apo, zozungulira zolimba zolimba zimakulitsa kukhulupirika kwa chitoliro, kuchepetsa chiopsezo cha kutulutsa kapena kuphulika.Kukhalitsa kumeneku kumapangitsa kuti madzi anu azikhala ndi moyo wautali, ndikuchepetsa mtengo wokonzanso ndikusintha.

2. Kukana dzimbiri:

Mizere yayikulu yamadzi imayang'aniridwa ndi zinthu zosiyanasiyana zachilengedwe, kuphatikiza chinyezi, mankhwala ndi nthaka.Mapaipi otchingidwa ndi Spiral nthawi zambiri amapangidwa pogwiritsa ntchito zida zosapanga dzimbiri monga zitsulo zosapanga dzimbiri, zomwe zimateteza dzimbiri, kukokoloka ndi mitundu ina ya dzimbiri.Kukana kumeneku kumawonjezera moyo wa mipope, kumalepheretsa kuwonongeka ndikusunga madzi abwino.

3. Kutsika mtengo:

Investing in spiral welded mapaipi kwachitoliro chachikulu chamadzisikhoza kukhala njira yotsika mtengo m'kupita kwanthawi.Kapangidwe kake kolimba komanso kukana kwa dzimbiri kumachepetsa kuchuluka kwa kukonzanso ndikusinthanso, motero zimapulumutsa ndalama zolipirira.Kuphatikiza apo, ndizosavuta kuziyika, zopepuka, komanso kuchepetsa kufunikira kwa zothandizira zowonjezera, zomwe zimawapangitsa kukhala njira yabwino komanso yotsika mtengo pama projekiti akuluakulu a mapaipi.

4. Kusinthasintha ndi Kusinthasintha:

Spiral welded chitoliro imapereka kusinthasintha kwakukulu komanso kusinthasintha pamagwiritsidwe ake.Zitha kupangidwa mosiyanasiyana, kutalika ndi makulidwe osiyanasiyana, kuwalola kuti azisinthidwa kuti akwaniritse zofunikira za polojekiti.Kusinthasintha kumeneku kumawathandiza kuti azitha kutengera malo osiyanasiyana komanso malo osiyanasiyana, kuwapanga kukhala chisankho chabwino kwambiri pamapaipi akuluakulu amadzi m'matauni ndi kumidzi.

5. Kusakhazikika kwa chilengedwe:

Kuphatikiza pa zabwino zake zogwirira ntchito, mapaipi opangidwa ndi spiral welded amathandizanso kuti chilengedwe chikhale chokhazikika.Zida zomwe zimagwiritsidwa ntchito pomanga ndizomwe zimatha kubwezeretsedwanso, zomwe zimachepetsa kuchuluka kwa mpweya wa carbon.Kuphatikiza apo, kapangidwe kake kopanda msoko kumachepetsa kutayika kwa madzi chifukwa cha kutayikira, motero kumateteza chida chofunikirachi.

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.

Pomaliza:

Kuwonetsetsa kuti mipope yanu yayikulu yamadzi ikugwira ntchito moyenera komanso yokhazikika ndikofunikira kuti mutsimikizire kupezeka kwamadzi odalirika.Kugwiritsa ntchito spiral welded pipe mu izichitoliro mizereimapereka zabwino zambiri, kuphatikiza mphamvu zowonjezera, kukana dzimbiri, kutsika mtengo, kusinthasintha komanso kukhazikika kwachilengedwe.Pamene tikugwira ntchito yomanga maziko amadzi okhazikika komanso ogwira mtima, kuyika ndalama muukadaulo wapamwamba ngati spiral welded pipe ndikofunikira.
