API 5L Qib B PSL2 SSAW Steel Yeeb Nkab yog qhov siab - cov kav dej zoo tsim los rau kev thauj mus los ntawm cov roj, roj av, thiab lwm yam dej hauv kev xav tau kev lag luam ib puag ncig. Tsim nyob rau hauv nruj raws li American Petroleum Institute (API) Specification 5L, cov khoom no ua ke nrog tus nqi -kev ua tau zoo ntawm kauv vuam nrog rau kev txhim kho kev ntseeg tau ntawm Cov Khoom Qhia Qib 2 (PSL2). Nws ua haujlwm tseem ceeb hauv cov kav dej sab nrauv thiab sab nrauv, muab cov khoom siv zoo tshaj plaws thiab kev ruaj ntseg zoo piv rau cov qauv PSL1 kav.

Spiral Welding Technology (SSAW)

‌Loj Diameter Muaj peev xwm: SSAW thev naus laus zis tso cai rau kev tsim cov kav loj - txoj kab uas hla (txog 3500mm) siv cov kav hlau nqaim, muab qhov yooj yim rau kev hloov kho me me.

‌Uniform Stress Distribution:Cov kauv weld faib cov kev ntxhov siab ntau dua ib ncig ntawm qhov ncig piv rau ncaj- cov kav dej seam, txhim kho cov qauv kev ntseeg siab nyob rau hauv siab.

‌Tus nqi -zoo:Kev siv cov khoom siv zoo thiab cov khoom siv hluav taws xob zoo tshaj plaws submerged arc vuam ua kom zoo ib yam weld zoo ntawm tus nqi sib tw.

Cov Kev Xav Tau Ntxiv (PSL2)

Tsis zoo li PSL1,PSL2imposes stricter cov kev cai ntawm cov tshuaj muaj pes tsawg leeg, mechanical zog, thiab xeem raws tu qauv:

‌Tshuaj muaj pes tsawg leeg:Tighter tswj ntawm Carbon Equivalent (CE), Phosphorus, thiab Sulfur cov ntsiab lus los xyuas kom meej weldability thiab toughness.

‌Mechanical Properties:Yuav tsum tau yam tsawg kawg nkaus yield zog ntawm245 MPa (35,500 psi)thiab tensile zog ntawm415 MPa (60,000 psi)‌.

‌Impact Testing: Yuav tsum tau Charpy V-Notch (CVN) cuam tshuam kev kuaj xyuas kom paub tseeb qhov tawv, tshwj xeeb tshaj yog rau qis- daim ntawv thov kub.

‌Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):100% kev tshuaj xyuas ultrasonic ntawm cov vuam seam thiab lub cev kom pom qhov tsis xws luag sab hauv, xyuas kom tsis muaj qhov txaus ntshai.

Daim ntawv thov

API 5L Qib B PSL2 SSAW kav yog dav siv hauv:

‌Roj & Roj Kis:Mainlines rau cov roj crude, natural gas, thiab refined khoom.

‌Dej & Slurry Pipelines:Kev thauj mus los ntawm dej, chav dej, thiab ntxhia slurries.

‌Qauv Piling: Lub hauv paus kev txhawb nqa rau cov txuas hniav, cov tsev, thiab cov ntug dej hiav txwv vim muaj kev thauj khoom siab -cov kabmob muaj peev xwm.

‌Industrial Fluid Transportation:Cov nroj tsuag tshuaj thiab cov chaw tsim hluav taws xob.
