Msika wa Mapaipi a Chitsulo a ASTM A53 ku North America: Kukula kwa Mayendedwe a Mafuta, Gasi ndi Madzi - Royal Group

North America ili ndi gawo lalikulu pamsika wapadziko lonse wa mapaipi achitsulo ndipo izi zikuyembekezeka kupitilira chifukwa cha kukwera kwa ndalama zomwe zimayikidwa pa zomangamanga zotumizira mafuta, gasi ndi madzi m'derali. Mphamvu yayikulu, kukana dzimbiri komanso kusinthasintha kwabwino zimapangitsa kuti zinthu zisinthe.Chitoliro cha ASTM A53ingagwiritsidwe ntchito m'mapaipi, m'malo operekera madzi mumzinda, m'mafakitale ndi zina zotero.

Chitoliro chachitsulo cha ASTM A53/A53M

Muyezo wa Mapaipi a ASTM A53: Buku Lophunzitsira Kugwiritsa Ntchito Mapaipi achitsulo a ASTM A53 ndi amodzi mwa miyezo yomwe imagwiritsidwa ntchito kwambiri pa mapaipi achitsulo padziko lonse lapansi pankhani yomanga mapaipi ndi zomangamanga. Pali mitundu itatu: LSAW, SSAW, ndi ERW, koma njira zawo zopangira ndi zosiyana ndipo kugwiritsa ntchito kwake ndi kosiyana.

1. Astm A53 LSAChitoliro cha Chitsulo cha W(Kuwotcherera kwa arc yonyowa kwa Longitudinal Submerged)
Chitoliro cha LSAW chimapangidwa popinda mbale yachitsulo m'litali kenako n’kuchilumikiza ndipo msoko wolumikizidwawo uli mkati ndi kunja kwa chitolirocho! Mapaipi a LSAW, okhala ndi zitsulo zapamwamba kwambiri, ndi abwino kwambiri pogwiritsira ntchito mafuta ndi gasi amphamvu kwambiri. Ma weld amphamvu kwambiri ndi makoma okhuthala zimapangitsa mapaipi awa kukhala oyenera kugwiritsa ntchito mapaipi a mafuta ndi gasi amphamvu kwambiri, komanso m'nyanja.

2. Astm A53SSAWChitoliro chachitsulo(Wolumikizidwa ndi Arc Wozungulira)
Chitoliro cha Spiral Submerged Arc Welded (SSAW) chimapangidwa pogwiritsa ntchito njira yolumikizira ya spiral submerged arc. Ma spiral weld awo amathandiza kupanga zinthu motchipa ndipo amawapangitsa kukhala abwino kwambiri pamagetsi apakati mpaka otsika kapena ogwiritsidwa ntchito m'nyumba.

3.Astm A53ERWChitoliro chachitsulo(Kukana Magetsi Kolumikizidwa)
Mapaipi a ERW amapangidwa ndi magetsi oletsa kupondereza, kotero kuti pamafunika utali wochepa wopindika kuti apinjidwe pokonzekera weld zomwe zimathandiza kupanga mapaipi okhala ndi mainchesi ang'onoang'ono okhala ndi welds yolondola, mtengo wopangira mapaipi otere ndi wotsika. Amagwiritsidwa ntchito kwambiri pomanga mafelemu omangira, mapaipi amakina, komanso kunyamula zakumwa pamphamvu yochepa.

Kusiyana kwakukulu ndi uku:

Njira YowotchereraNjira za LSAW/SSAW zimaphatikizapo kuwotcherera arc pansi pa madzi, ERW ndi njira yowotcherera yolimbana ndi magetsi.

M'mimba mwake & Kukhuthala kwa KhomaMapaipi a LSAW ali ndi mainchesi akuluakulu okhala ndi makoma okhuthala poyerekeza ndi mapaipi a SSAW ndi ERW.

Kusamalira Kupanikizika: LSAW > ERW/SSAW.

Zochitika Zamsika ku North America

Msika wa North America waChitoliro chachitsulo cha ASTM A53Mtengo wake ndi pafupifupi USD 10 biliyoni mu 2025 ndipo akuyembekezeka kukula pa CAGR ya 3.5-4% mu 2026-2035. Kukula kumalimbikitsidwa ndi kusintha kwa zomangamanga, kukula kwa gawo la mphamvu, ndi kukweza njira zamadzi m'mizinda.

Ntchito Zofunika Kwambiri Zomwe Zimakhudza Kufunika kwa Anthu

Mayendedwe a Mafuta ndi Gasi: Pipe ya mafuta ndi gasiikupitilizabe kulamulira msika wa mapaipi a ASTM A53 ndi gawo la 50–60% la kugwiritsidwa ntchito kutsatiridwa ndi mapaipi a gasi wachilengedwe ndikuthandizidwa ndi chitukuko chachikulu cha gasi wa shale komanso mapulojekiti osinthira mapaipi.

Kachitidwe ka Kupereka Madzi ndi ZimbudziKufunika kwa madzi kukuwonjezekanso chifukwa cha kusinthidwa kwa zomangamanga za mzinda ndi njira zoperekera madzi ndipo ndi 20-30% ya ndalama zonse zomwe zimagwiritsidwa ntchito.

Ntchito Yomanga ndi Kapangidwe ka NyumbaMapaipi a ASTM A53 akugwiritsidwa ntchito kwambiri pomanga nyumba ndi makina oyendera nthunzi, komanso ntchito zina zomangira ndipo izi zimafikira 10% mpaka 20%.

Malingaliro a Tsogolo

Zikuyembekezeka kuti msika wa kumpoto kwa America udzawona kukula kwa mapaipi achitsulo a ASTM A53 chifukwa cha kuwonjezeka kwa ndalama zomwe maboma ndi mafakitale amagwiritsa ntchito pa mapaipi otetezeka, ogwira ntchito bwino, komanso okhalitsa. Ngakhale pali zovuta monga mitengo yosasinthasintha ya zinthu zopangira, kupsinjika kwa malamulo, komanso mpikisano wochokera ku zipangizo zina, kuzimitsa ndi kusakweza mapaipi achitsulo a ASTM A53 kupitilirabe kukhala chinthu chofunikira kwambiri pamapulojekiti oyendetsera mafuta, gasi ndi madzi.

Motero, chifukwa cha kudalirika kwawo komanso kusinthasintha kwawo, mapaipi achitsulo a ASTM A53 ku North America apitiliza kukhala maziko a zomangamanga zamakono kwa zaka khumi zikubwerazi.
