API 5L X42 chitoliro chachitsulo, yomwe imadziwikanso kuti L290, imatchulidwa chifukwa cha mphamvu zake zochepa zokolola za 42,100 psi (290 MPa).X42 ili ndi mphamvu yocheperako ya 60,200 psi (415 MPa).
X42 / L290 kalasi zitsulo chitoliro ndi wa m'munsi kalasi ndipo zimagwiritsa ntchito ndi otsika kuthamanga.Monga kutumizira kwa gasi wamzinda, njira zotumizira madzi, ndi mapaipi ena omwe safuna kunyamula mwamphamvu kwambiri.
Miyezo
Kutengera ndi magwiridwe antchito, machubu a X42 amagawidwa m'magulu awiri azinthu,PSL1 ndi PSL2.
PSL1ndi zofunika kalasi mzere chitoliro specifications.Nthawi zambiri amagwiritsidwa ntchito m'mayendedwe okhazikika momwe chilengedwe chimakhala chocheperako.
PSL2ndi giredi yapamwamba kwambiri.Amapangidwa kuti azigwira ntchito zovuta kwambiri, monga malo oponderezedwa kwambiri, komanso kugwiritsa ntchito zovuta kapena zowononga.
Kusankhidwa kwa chitoliro chachitsulo chogwiritsira ntchito kumadalira zofunikira zenizeni za polojekitiyi, kuphatikizapo malo omwe akufunidwa kuti agwiritsidwe ntchito komanso zosowa zolimba.
Njira Yopangira Chitoliro cha Chitsulo
Kupanga machubu achitsulo a X42 kumakwirira njira zingapo zopangira kuti zikwaniritse zosowa zaumisiri ndi chilengedwe.Kuchokera ku zopanda msoko kupita ku mitundu yosiyanasiyana ya njira zowotcherera, njira iliyonse imapereka ubwino wake wapadera ndi malo ogwiritsira ntchito.

PSL2 ili ndi mphamvu zowongolera zamtundu wamankhwala kuti zitsimikizire kuti zili bwino komanso zimagwira ntchito bwino m'malo ovuta kwambiri ndikugwiritsa ntchito.
Magiredi ena a PSL2 chubing adapangidwa kuti azigwiritsidwa ntchito mwapadera, kuphatikiza zomata "S" ndi "O".Chokwanira cha "S" chikuwonetsa kuti chitolirocho chimapangidwira malo owawa, pomwe mapaipi okhala ndi "O" amapangidwira madera akunyanja.
Chifukwa maderawa ndi owononga kwambiri, kukana kwa dzimbiri kwa chitoliro chachitsulo kumakhala bwino posintha kapangidwe kake.

Ubwino wa X42 Grade Steel Tubing
1. Mmphamvu yapakatikati ndi kulimba: Chitoliro chachitsulo cha X42 chili ndi mphamvu zochepa zokolola za 42,100 psi (290 MPa), zomwe zimapereka mphamvu zamakina zabwino pamene zimakhala zolimba zokwanira kuti zipirire kupsinjika kwa mkati ndi kunja popanda kusweka.
2. Weldability wabwino: Chitoliro cha X42 nthawi zambiri chimakhala ndi weldability wabwino, zomwe zimapangitsa kuti zikhale zosavuta komanso zotsika mtengo kukhazikitsa ndi kukonza.Izi ndizofunikira makamaka pamapulojekiti a mapaipi akutali, omwe nthawi zambiri amafunikira ntchito yowotcherera.
3.Oyenera ntchito zotsika komanso zapakatikati-zapakati: Chifukwa cha mphamvu zake zokolola zochepetsetsa, ndizoyenera kwambiri kugwiritsira ntchito zochepetsera zochepa komanso zapakatikati monga kufalitsa gasi wa municipalities, machitidwe ogawa madzi otsika kwambiri, ndi zina zotero. Izi zimapangitsa kuti zikhale zabwino kwa ntchito zambiri zamatauni ndi mafakitale.
4.Kuchita bwino kwa ndalama: Poyerekeza ndi magiredi apamwamba (mwachitsanzo X65, X70, etc.), chitoliro chachitsulo cha X42 nthawi zambiri chimakhala chopindulitsa pakupanga ndi kugula.
5. Zosiyanasiyana kugwiritsa ntchito: Imapereka zosankha zingapo pazofunikira zosiyanasiyana zamapulojekiti, pomwe PSL1 ili yoyenera pazofunikira zamtundu wamba ndipo PSL2 ndiyoyenera kugwiritsa ntchito pomwe pamafunika kuchita bwino kwambiri.
6. Kupanga kokhazikika: Monga gawo la muyezo wa API 5L, kupanga ndi kuwongolera khalidwe la chitoliro chachitsulo cha X42 kumatsatira mfundo zokhwima zamakampani, zomwe zimatsimikizira kusasinthika kwake komanso kudalirika.
X42 Steel Pipe Application
1. Kuyendetsa mafuta ndi gasi: Zomwe zimagwiritsidwa ntchito pomanga mapaipi amafuta ndi gasi pamagawo amafuta ndi gasi.Chitoliro chamtundu woterechi chimatha kunyamula bwino komanso moyenera mafuta amafuta, gasi ndi zinthu zina zamafuta, makamaka oyenera kumayendedwe apakatikati komanso otsika kwambiri.
2. Paipi yamadzi: Amagwiritsidwanso ntchito pamayendedwe amadzi ndi zonyansa.Chifukwa cha kukana kwake kwa dzimbiri komanso mphamvu zamapangidwe, imatha kugwiritsidwa ntchito pamapaipi akulu ndi nthambi zotumizira, zoyenera kuperekera madzi akumizinda ndi machitidwe amadzi am'mafakitale.
3. Ntchito zomanga ndi zomangamanga: M'makampani omanga, atha kugwiritsidwa ntchito ngati gawo lazothandizira ndi mafelemu.Mphamvu zake ndi kuwotcherera kwake kumapangitsa kukhala chinthu chabwino chomangira milatho, zothandizira misewu, ndi zida zina.
4. Malo opangira magetsi: M'makampani opanga magetsi, makamaka m'malo ophatikizika ndi magetsi, chitoliro chachitsulo cha X42 chimagwiritsidwa ntchito kunyamula nthunzi ndi madzi otentha, zomwe zimathandiza kusunga mphamvu zamagetsi m'malo awa.
X42 Chitoliro Chofanana Chofanana
1. EN 102082 L290NB: L290 imatanthawuza mphamvu zochepa zokolola za 290 MPa.NB imayimira mayendedwe okhazikika kapena okhazikika ndipo ndiyoyenera kugwiritsa ntchito ngati mafuta ndi gasi.
2.ISO 3183 L290: Gulu la L290 la ISO 3183 ndilofanana kwambiri ndi API 5L X42 potengera kapangidwe ka mankhwala ndi makina.
3. GB/T 9711 L290: Uwu ndiye muyeso waku China wamapaipi achitsulo, ndipo L290 ndi ofanana ndi API 5L X42 potengera mphamvu zokolola zochepa.
4. ASTM A106 Gawo B: Ngakhale ambiri ntchito kwa seamless mpweya zitsulo chitoliro, ASTM A106 kalasi B angagwiritsidwe ntchito ngati njira ina welded zitsulo chitoliro nthawi zina, makamaka m'madera sanali pressurized.
Posankha chinthu chofanana, ndikofunikira kuwonetsetsa kuti zomwe zasankhidwa zikukwaniritsa zofunikira zamakina, makina amakina, ndi milingo ina yoyenera pakugwiritsa ntchito.Kuphatikiza apo, njira zopangira zinthu, zotsimikizira zaubwino, komanso zotsika mtengo zingafunikire kuganiziridwa.
Zambiri zaife
Chiyambireni kukhazikitsidwa mu 2014, Botop Steel yakhala ikugulitsa chitoliro chachitsulo cha carbon ku Northern China, chomwe chimadziwika ndi ntchito zabwino kwambiri, zinthu zamtengo wapatali, komanso zothetsera mavuto.
Kampaniyo imapereka mapaipi osiyanasiyana azitsulo za kaboni ndi zinthu zina,
kuphatikizapo zitsulo zopanda msoko, ERW, LSAW, ndi SSAW chitoliro chachitsulo, komanso mzere wathunthu wazitsulo ndi ma flanges.Zopangira zake zapadera zimaphatikizanso ma aloyi apamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zofunikira zama projekiti osiyanasiyana amapaipi.
