Pipeline

PG& E yog ua phem rau kev ruaj ntseg ntawm cov zej zog nws pab raws li thiab ua hauj lwm txhim khu pipeline kev ruaj ntseg thoob qaum teb thiab hab txhawb California. Tseem ceeb rau qhov kev siv zog no yog qhov kev soj ntsuam ntawm PG&E tus ze li ntawm 7,000 mais ntawm roj transmission pipelines thiab 42,000 mais ntawm tis pipelines. Yog nquag xyuas thiab soj ntsuam cov tes hauj lwm ntawm roj pipelines, PG&E yuav tau paub thiab chaw nyob tej kev txhawj xeeb ua ntej lawv ua ib qho teeb meem.

PG& E yog ib tug tswv cuab hauv tsim thiab deploying tshiab yees uas yog pab transform hlauv taws xob rau hauv predictive thiab proactive tswv thiab pab muab kev soj ntsuam xyuas—feem ntau nyob rau lub sij hawm tsawg thiab muaj ntau dua accuracy thiab precision dua tsoos txoj kev tsoos.

3D Toolbox

PG& E ua hauj lwm nrog lub tshuab tshiab uas zoo li lus ceeb toom, xws li dents, cracks los yog corrosion, nyob sab nraum roj pipelines. 3D Toolbox yog ib qho yooj yim uas siv raws li ib lub koob yees duab, thiab nrog ib nyem, nws captures ib cov duab thiab muab kev ntsuas—muab PG&E real-time ntaub ntawv hais txog cov mob pipeline qhov chaw. Lub tshuab no tso cai pipeline engineers thiab corrosion ua hauj lwm saib dluab rau ib laptop ntawm qhov chaw khawb, ntsuam xyuas tej defects los yog teeb meem tsis pub dhau feeb thiab muab ua ke ib txoj kev npaj kho tam sim ntawd. Tsis tas li, ib qho loj kom zoo dua qhov lawv yog tias nws muab ib traceable cov ntaub ntawv ntawm qhov kev ntsuas, uas engineers yooj yim khw thiab saib cov ntaub ntawv yav tom ntej.

EXAscan

PG&E kuj utilizes ib portable, handheld 3D laser scanner hu ua tus EXAscan. Tus EXAscan yuav tau hloov lub sij hawm consuming manual tasks thiab muab ib tug ntau paub meej ntxiv txog ib pipeline dua twb muaj yav tas los tsis muaj. Nws yuav ntsuas, piv txwv li, cov neeg uas lwm corrosion los yog characterize tej warping.

Ib tug engineer kawm engineer los yog technician tsuas tuas cov scanner ob peb nti saum ib seem ntawm pipeline. Tus ntaus transmits cov ntaub ntawv rau ib lub computer program, uas tsim ib tug qauv 3D qauv ntawm cov khoom thiab zaub nws rau ib tug saib xyuas. Cov software muaj xws li xim coding qhia qhov twg pipeline puas yog loj tshaj, nrog rau ntau lwm yam kev ntsuas. Cov ntaub ntawv yog tsis pub dhau 40 microns, los yog 0.0016 ntawm ib nti.

Hydrostatic kuaj

Hydrostatic kuaj yuav pressurizing ib pipe nrog dej los qhia tej weaknesses thiab yog ib txoj kev proven txoj kev kom paub tseeb tias lub peev xwm ntawm ib nkev pipeline khiav lag luam ntawm ib theem zoo siab. Hydrostatic kuaj no kuj siv los kuaj tej yam khoom li scuba tanks, hluav taws extinguishers thiab cua compressor tanks.

Hydrostatic siab kuaj. entails sau ib pipe nrog dej, pressurizing nws rau ib theem ntau dua cov kav dej yuav puas khiav lag luam nrog tej nkev thiab ces xyuas cov kav dej rau kwv yees li ntawm yim teev. Txij xyoo 2011, PG&E muaj siab kuaj ntau tshaj 673 mais ntawm tej nkev transmission pipelines thoob plaws hauv nws qhov kev pab cuam.

PG& E koomtxoos ob roj transmission thiab tis lawv nyob hauv lub teb chaws thiab tau ua teeb meem loj nyob rau hauv accelerating leak kho thiab tiv thaiv thoob nws 80,000-mais nkev lawv.

Thaum kawg ntawm 2014, PG&E hloov 2,270 mais ntawm nws cov cam khwb cia hlau thiab ua ntej 1940 steel distribution main—uas yuav prone los leaks—nrog niaj hnub, khoom tshiab. Qhov no txhais tau tias PG& E yog ib tus thawj hlauv taws xob ntawm comparable thiab hnub nyoog kom tiav tej tes hauj lwm.

Kev nyab xeeb ntawm cov raj roj

PG& E yog ua phem rau lub tsev cov kev ruaj ntseg thiab feem ntau txhim khu kev qha lawv nyob hauv lub teb chaws, kom peb yuav tau muab lub zog uas peb cov neeg muas zaub yuav nyob ntawm ntau xyoo lawm los.

Safer pipelines thoob peb lub xeev

PG& E muaj heev pipeline kev ruaj ntseg, txoj cai thiab cov txheej txheem nyob rau hauv qhov chaw kom muaj kev ruaj ntseg ntawm peb cov neeg muas zaub, cov neeg ua hauj lwm thiab pej xeem.

• Pipeline access: Tuav lub cheeb tsam saum peb pipelines thiab ensuring crews muaj npaj saib yog ib feem tseem ceeb ntawm peb muaj peev xwm muaj kev ruaj ntseg khiav lag luam.
• Lub regional pipelines: Loj-diameter transmission pipelines muaj tej nkev thoob peb lub xeev.
• Neeg zej zog pipelines: Smaller-diameter tis pipelines pab hauv zos thiab cov lag luam.
• Maintenance thiab xyuas: Txawm qhov luaj li cas, peb saib peb raws li txoj cai nyob rau lub sij hawm tiag rau ib lub hauv paus 24-teev, thiab los ntawm kev sojntsuam thiab patrols.
