Chifukwa cha luso lathu komanso kuzindikira kwathu kukonza, kampani yathu yadzipezera mbiri yabwino pakati pa makasitomala padziko lonse lapansi chifukwa cha API 5L 5CT Psl1/ Psl2 X42/X52/X46/X56/X60/X65/X70/X80 Seamless Line Steel. Mapaipi, Kulimbikitsidwa ndi msika womwe ukupanga mwachangu pazakudya ndi zakumwa zachangu padziko lonse lapansi , Tikuyembekezera kugwira ntchito ndi anzathu/makasitomala kuti tipeze zotsatira zabwino limodzi. Takhala tikupanga ukadaulo watsopano kuti tithandizire kupanga, ndikupereka zinthu zotsika mtengo komanso zapamwamba kwambiri! Kukhutira kwamakasitomala ndizomwe timayika patsogolo! Mutha kutilola kuti tidziwe lingaliro lanu kuti mupange mapangidwe apadera amtundu wanu kuti tipewe magawo ofanana pamsika! Tikupatsirani ntchito yathu yabwino kwambiri kuti mukwaniritse zosowa zanu zonse! Chonde titumizireni nthawi yomweyo!

Chitoliro cha payipi: Mafuta, gasi kapena madzi otengedwa pansi amatengedwa kupita ku mafakitale amafuta ndi gasi ndi payipi yapaipi. mapeto a socket; Njira yolumikizira ndikuwotcherera, kulumikiza kolala, kulumikizana kwa socket ndi zina zotero.

Chitoliro cha chitoliro: mafuta, gasi kapena madzi otengedwa pansi amatumizidwa ku mafakitale a mafuta ndi gasi ndi pipeline pipe.Welded chitoliro cholumikizidwa ndi chitoliro chosakanikirana chowotcherera, nthawi zambiri kutalika kwake kumakhala kotalika, kumatha kukhutiritsa misa ya wogwiritsa ntchito, koma kukhazikika. Si bwino ngati umodzi Integrated mulu wa seamless chubu, koma zambiri zazifupi kutalika kwa chubu wopanda msoko, sangathe kukhutiritsa ogula ntchito mtunda wautali, ogula ndi ntchito ndondomeko ayenera kupanga collocation ntchito onse. mitundu iwiri ya chitoliro chopanda msoko ndi chowotcherera, mapeto a chitoliro ali ndi mapeto athyathyathya, mapeto a ulusi ndi malekezero azitsulo; Njira yolumikizira ndi yowotcherera, kugwirizana kwa kolala, kugwirizana kwazitsulo ndi zina zotero.

Ndi chitukuko cha payipi zitsulo mbale luso ndi kupita patsogolo kwa welded chitoliro kupanga, luso kuwotcherera, ntchito osiyanasiyana chitoliro ndi welded chitoliro mu kukula pang'onopang'ono, makamaka lalikulu m'mimba mwake welded chitoliro kalasi kukula mwayi wonyowa kwambiri, ndi mtengo. zinthu, welded chitoliro wakhala lalikulu m'munda wa mzere chitoliro, amene amalepheretsa chitukuko cha zitsulo zosapanga dzimbiri zitsulo mzere chitoliro.

API5L payipi kupanga chitoliro panopa ntchito microalloying Kutenthetsa njira mankhwala, zitsulo zosapanga dzimbiri chitoliro mtengo kupanga ndi apamwamba kwambiri kuposa chitoliro welded, ndi kusintha kalasi zitsulo, monga X80 zitsulo kalasi chitoliro pa malire a mpweya wofanana, ndondomeko ochiritsira. wa chitoliro chosasunthika chachitsulo ndizovuta kukwaniritsa zofunikira za ogwiritsa ntchito

Kufala zitsulo chitoliro anawagawa PSL1, PSL2 kalasi mankhwala awiri, kusiyana kwakukulu ndi kuti PSL2 poyerekeza ndi PSL1 pa carbon ofanana, kuthyoka kulimba, pazipita zokolola mphamvu ndi pazipita kumakoka mphamvu amafuna.Kulamulira zinthu zoipa monga phosphorous ndi sulfure ndi okhwima.Kuyesa kosawonongeka kwa machubu opanda msoko ndikofunika.Zomwe zili mu chitsimikizo ndi kufufuza pambuyo poyesera ndizovomerezeka.

Zofunikira zazikulu zamapaipi amafuta ndi gasi pazitsulo ndi:

1. Mphamvu: Mapaipi ambiri amafuta ndi gasi amapangidwa molingana ndi mphamvu zokolola za steel.Pipes zokhala ndi mphamvu zokolola zambiri zimatha kupirira kupanikizika kwakukulu kogwira ntchito.

2. Kulimba: Kulimba kwambiri kwa chitoliro chachitsulo kumatha kubweretsa ngozi yocheperako yapaipi yamafuta ndi gasi, kotero API 5L imati, kuwonjezera pa zinthu wamba zamakina, kuyesa kwa v-notch Charpy ndi kuyesa kung'amba nyundo kuyenera kuwonjezeredwa, ndi chitsulo chitoliro ayenera mosamalitsa nondestructive kuyezetsa asanachoke fakitale.

3. Weldability: Chifukwa cha malo ovuta kumunda pakuyika mapaipi, kuwotcherera kwabwino kumafunika pakuwotcherera matako a mapaipi achitsulo. Mapaipi okhala ndi weldability otsika amakhala ndi ming'alu pa msoko wowotcherera pakuwotcherera, zomwe zidzakulitsa kuuma ndi kulimba kwa msoko wowotcherera. ndi malo okhudzidwa ndi kutentha, ndikuwonjezera kuthekera kwa kupasuka kwa payipi.Mfundo yopangira zitsulo zowotcherera ndi kulamulira kwa martensite kusintha malo ndi kuuma.Malingana ndi chikoka cha alloying element pa martensite transition point ndi zochitika zenizeni, ndondomeko yowerengera ya mpweya wofanana angagwiritsidwe ntchito kuwunika weldability wa steel.Generally, ofanana mpweya ayenera kulamulidwa pansipa 0,4%. Ndipotu, mphero zambiri zazitsulo zimayendetsedwa pansi pa 0,35%.

4. Ductility: Ngati ductility sikokwanira, izo zidzatsogolera kupanga zitsulo mbale kugawanika pa ozizira kupinda kapena cambium fracture pa kuwotcherera.Choncho, muyezo API welded chitoliro kunja kwa mayeso okhazikika flattening, komanso amafuna kasitomala kutsogoleredwa. ozizira kupinda mayeso. Chinsinsi kuwongolera ductility ndi kuchepetsa inclusions sanali zitsulo zitsulo ndi kulamulira morphology ndi kugawa inclusions.

5. Kulimbana ndi dzimbiri: popereka mafuta a sulfure ndi gasi, hydrogen sulfide ndi carbon dioxide m'madzimadzi zimapangitsa kuti hydrogen imbrittlement ndi kupsinjika kwa dzimbiri kusweka kwa machubu achitsulo. ambiri adopted.Makhalidwe ake aakulu ndi microalloying ndi kugudubuzika ankalamulira, amene angapeze mphamvu mkulu, kulimba mkulu, pulasitiki mkulu ndi weldability wabwino pansi pa kutentha anagubuduza condition.Kuti kukwaniritsa mokwanira ntchito zofunika mapaipi amafuta ndi gasi zitsulo, okhwima aloyi kamangidwe. , sulfure, phosphorous ndi zinthu zina zoipa ndi okhwima kwambiri control.Generally, sulfure ndi zosakwana 0.01% kusintha plasticity ndi kulimba kwa chitsulo, makamaka yopingasa toughness.

Kugwiritsa ntchito

Paipiyi imagwiritsidwa ntchito kunyamula mafuta, nthunzi ndi madzi otengedwa kuchokera pansi kupita kumakampani amafuta ndi gasi kudzera papaipi.

Kuyesedwa kwa Hydrostatic

Chitoliro chopirira kuyesedwa kwa hydrostatic popanda kutayikira kudzera mumsoko wowotcherera kapena thupi la chitoliro. Zolumikizira siziyenera kuyesedwa ndi hydrostatic kupereka magawo a mapaipi omwe amagwiritsidwa ntchito adayesedwa bwino.

Bend mayeso

Palibe ming'alu yomwe idzachitika pagawo lililonse lachiyeso ndipo palibe kutsegulidwa kwa weld komwe kudzachitika.

Mayeso osalala

Njira zovomerezera mayeso a flattening ziyenera kukhala:

• EW mapaipi D<12.750 mu:
• X60 yokhala ndi T500in. Sipadzakhala kutsegula kwa kuwotcherera pamaso mtunda pakati pa mbale ndi zosakwana 66% ya awiri oyambirira kunja awiri. Kwa magiredi onse ndi khoma, 50%.
• Pakuti chitoliro ndi D/t> 10, sipadzakhala kutsegula kwa kuwotcherera mtunda pakati pa mbale ndi zosakwana 30% ya choyambirira kunja awiri.
• Kwa kukula kwina tchulani API 5L yathunthu.

Kuyesa kwamphamvu kwa CVN kwa PSL2

Mapaipi ambiri a PSL2 ndi magiredi amafuna CVN. Chitoliro chopanda msoko chiyenera kuyesedwa m'thupi. Welded chitoliro ayenera kuyesedwa mu thupi, chitoliro kuwotcherera ndi kutentha bwanji zone. Onani tsatanetsatane wathunthu wa API 5L pa tchati cha makulidwe ndi magiredi ndi mphamvu zomwe zimafunikira mphamvu.
