kev tsim khoom

Nta thiab Qhov Zoo

‌High Dimensional Accuracy:Cov txheej txheem tsim thiab nthuav dav kom paub meej qhov ntev, ua kom yooj yim dua ntawm - qhov chaw vuam thiab kev teeb tsa.

‌Zoo heev Weld Quality:Cov txheej txheem SAW ruaj khov ua kom muaj kev sib raug zoo, siab -kev ncaj ncees welds nrog qhov tsis xws luag.

‌Superior Mechanical Properties:‌ Los ntawm TMCP thiab normalizing kev kho mob, cov kav dej muaj lub zog siab, zoo qis -kub toughness, thiab tswj tawm los ntawm -rau -tensile ratio (piv txwv li, qis dua 0.85), txhim kho hom-raws li kev tsim muaj peev xwm rau cov cheeb tsam nyuaj.

‌Comprehensive Quality Control:Kev tsim khoom ua raws li API 5L cov qauv nruj me ntsis. Kev lees paub zoo suav nrog kev tshuaj xyuas cov tshuaj lom neeg muaj pes tsawg leeg, kev tshuaj xyuas cov cuab yeej cuab tam (tensile, cuam tshuam), thiab tsis yog - kev kuaj xyuas puas tsuaj (UT, ET). High- cov khoom qib siab feem ntau siv Automated Ultrasonic Testing (AUT). Qhov tseem ceeb, txhua cov yeeb nkab tau dhau los ua qhov yuav tsum tau ntsuas hydrostatic siab, uas tsis tuaj yeem hloov tau los ntawm NDE raws li API cov qauv.

‌Tsawg Residual Stress:Cov txheej txheem puv -ntev nthuav dav ua tau zoo txo qis thiab sib npaug faib cov kev ntxhov siab sab hauv, pab tiv thaiv kev ntxhov siab corrosion tawg.

‌Nto Coatings

Txhawm rau txhim khu kev ruaj ntseg hauv ntau qhov chaw, LSAW cov kav dej tuaj yeem muab cov txheej txheem tiv thaiv.

Cov kev xaiv muaj xws li Dub painting, Fusion Bonded Epoxy (FBE), 3-txheej Polyethylene (3PE), 3-txheej Polypropylene (3PP),

coal tar epoxy, thiab bitumen txheej.

Daim ntawv thov

‌Ntev -Ntaus Roj & Roj Kis:Cov ntawv thov tseem ceeb rau qib siab - qib LSAW kav (xws li X70, X80) yog nyob rau hauv qhov loj hla- lub teb chaws cov kav dej rau cov roj thiab cov nkev.

‌Lub Nroog Gas Distribution & Industrial Networks:Siv nyob rau hauv nroog gas grids, chemical cog piping, thiab cov tswv yim petroleum reserve chaw.

‌Demanding Environment Pipelines:Tsim nyog rau cov ntawv thov nyuaj xws li cov kav dej hauv hiav txwv / dej hiav txwv, thaj chaw arctic, thaj chaw permafrost, thiab thaj chaw seismic, qhov uas yuav tsum muaj rau siab toughness, strain peev, thiab corrosion kuj (tshwj xeeb tshaj yog tiv thaiv H2S) yog qhov tseem ceeb.

kev tswj kom zoo
