Chiyambi cha Hardbanding

Kupaka zitsulo zolimba kumatchinga zitsulo zosamva kuvala Kumanga kwachitsulo Kumangirira ndi njira yoyala pamwamba pa chitsulo cholimba] pa chitsulo chofewa. Amagwiritsidwa ntchito ndi kuwotcherera kwachitsulo cha gasi pamtunda wakunja wa zida zobowola kuti awonjezere kulumikizana kwa chitoliro, makola, ndi moyo wautumiki wapaipi yobowola zolemetsa komanso kuchepetsa kuvala kwa zingwe zomangira zomwe zimayenderana ndi kubowola.

Kumanga kolimba kumagwiritsidwa ntchito pamene mikangano yozungulira ndi ya axial yokhudzana ndi kubowola ndi kupunthwa kumapangitsa kuti pakhale ma abrasive abrasive pakati pa chingwe chobowola ndi casing kapena pakati pa chingwe chobowola ndi thanthwe. Zophimba zolimba za alloy zimagwiritsidwa ntchito kumalo omwe amalumikizana kwambiri. Nthawi zambiri, hardbanding imagwiritsidwa ntchito pagulu la zida chifukwa ndi gawo lalikulu kwambiri la chingwe chobowola ndipo limalumikizana ndi casing nthawi zambiri.

Poyambirira, tinthu tating'onoting'ono ta tungsten-carbide tidaponyedwa muzitsulo zachitsulo zofewa, zomwe zidakhalabe muyezo wamakampani kwazaka zambiri. Komabe, posakhalitsa eni ake adazindikira kuti ngakhale cholumikizira chidali chotetezedwa bwino, tinthu tating'onoting'ono ta tungsten-carbide nthawi zambiri timakhala ngati chida chodulira chotchinga, zomwe zimapangitsa kuti pakhale kuwonongeka kwambiri komanso nthawi zina kulephera kwa casing. Kuthana ndi kufunikira kofunikira kwa chinthu cholimba cha casing-friendly chomwe chingateteze mokwanira zida zolumikizira zida ndi zida zina zapabowo.

Mitundu ya hardbanding:

1. Kukwezedwa kolimba (KUNYADIRA)

2. Flush hardbanding (FLUSH)

3. Kumanga kwapakati pa Drill Collar ndi Heavy Weight Drill Pipe

Zochita za Hardbanding:

1. Imateteza chitoliro chobowola cholumikizira kuti chisakhumudwe ndi kutha ndikuwonjezera moyo wautumiki wa DP.

2. Imateteza zida zolumikizirana kuti zisakanike.

3. Amachepetsa kuvala kwa casing.

4. Amachepetsa kuwonongeka kwa mikangano pobowola.

5. Hardbanding amalola ntchito ang'ono OD welded zida olowa.

Mapulogalamu a Hardbanding:

1. Hardbanding imagwira ntchito pobowola mapaipi amitundu yonse ndi magiredi.

2. Zida zolimba zitha kugwiritsidwa ntchito pa new and u    sed tubular.

3. Hardbanding angagwiritsidwe ntchito pobowola chitoliro olowa chida anapanga pa GOST R 54383-2011 ndi GOST R 50278-92 kapena pa specifications luso dziko mphero chitoliro, ndi pa kubowola chitoliro olowa chida anapanga pa API Spec 5DP.

4. Kumanga mwamphamvu kungagwiritsidwe ntchito pamapaipi obowola ndi mitundu yosiyanasiyana ya zida zolumikizira, kuphatikiza zida zamapewa awiri.

5. Zomangamanga zolimba zitha kugwiritsidwa ntchito pa mapaipi obowola osazizira komanso DP ya sour-service.

Zomangamanga zitha kugwiritsidwa ntchito pamachubu amitundu ndi makulidwe awa:

1. Thupi la chitoliro OD 60 mpaka 168 mm, kutalika mpaka 12 m, OD ya zida zolumikizira zida pazolemba za DP.

2. Kumanga kolimba kumagwiritsidwa ntchito pa kusokonezeka kwa HWDP, pazida zolumikizana za HWDP, ndi DC zamitundu yonse ndi makulidwe.

3. Kumanga mwamphamvu kumagwiritsidwanso ntchito kusokoneza pakati pa HWDP ndi DC.

4. Zomangira zolimba zitha kugwiritsidwa ntchito pazolumikizira zida zisanayambe kuwotcherera ku chitoliro chobowola.

Ndalama zomwe zimapangidwa pogwiritsa ntchito chitoliro chobowola ndi hardbanding:

1. Moyo wautumiki wa chitoliro chobowola umakulitsidwa mpaka katatu.

2. Kuvala kwa zida kumachepetsedwa ndi 6-15 % kutengera mtundu wa zomangira zolimba zomwe zimagwiritsidwa ntchito.

3. Kuvala kwakhoma kumachepetsedwa ndi 14-20% poyerekeza ndi kuvala komwe kumachitika chifukwa cha zida zolumikizira.

4. Amachepetsa kuwonongeka kwa chitsime.

5. Torque yofunikira yozungulira imachepetsedwa, motero kuchepetsa kugwiritsa ntchito mphamvu.

6. Kupititsa patsogolo kubowola ntchito.

7. Amachepetsa nthawi yoboola.

8. Amachepetsa kuchuluka kwa chingwe chobowola ndi kulephera kwa zingwe pobowola.
