Selelekela sa Hardbanding

Hardbanding ke ho koaheloa ka tšepe ha tšepe Hardbanding ke mokhoa oa ho beha holim'a lera kapa holim'a tšepe e thata] karolong e bonolo ea tšepe. E sebelisoa ka tjheseletsa ea tšepe ea khase ka holim'a bokantle ba lisebelisoa tsa liphaephe tsa ho cheka ho eketsa lisebelisoa tsa lipeipi tsa ho cheka, li-collar, le bophelo ba tšebeletso ea liphaephe tsa boima bo boima le ho fokotsa ho roala ha likhoele tse amanang le mekhoa ea ho cheka.

Hardband e sebelisoa moo khohlano ea ho potoloha le axial e amanang le ho phunya le ho khoptjoa ho etsang hore ho be le maqeba a feteletseng pakeng tsa khoele ea ho phunya le casing kapa pakeng tsa khoele ea ho phunya le lejoe. Li-overlays tsa li-hard alloy li sebelisoa libakeng tse kholo ka ho fetisisa. Hangata, hardbanding e sebelisoa ho motsoako oa sesebelisoa kaha ke karolo e pharaletseng ka ho fetisisa ea khoele ea ho cheka 'me e tla kopana le casing hangata.

Qalong, likaroloana tsa tungsten-carbide li ile tsa theoleloa ka har'a matrix a tšepe e bonolo, e ntse e le boemo ba indasteri ka lilemo tse ngata. Leha ho le joalo, beng ba liliba kapele ba ile ba hlokomela hore le hoja motsoako oa sesebelisoa o ne o sirelelitsoe hantle, likaroloana tsa tungsten-carbide hangata li ne li sebetsa e le sesebelisoa sa ho itšeha khahlanong le casing, e leng se bakang litekanyetso tse feteletseng tsa ho senyeha le ho hlōleha ho feletseng ka linako tse ling. Ho sebetsana le tlhokahalo ea bohlokoa ea sehlahisoa se thata sa casing-friendly se ka sireletsang manonyeletso a lisebelisoa le lisebelisoa tse ling tsa fatše.

Mefuta ea li-hardbanding:

1. Ho phahamisoa ka thata (HOIKHALITSA)

2. Flush hardbanding (FLUSH)

3. Hardbanding ka ho ferekana bohareng ba Drill Collar le Heavy Weight Drill Pipe

Mesebetsi ea Hardbanding:

1. E sireletsa lenonyeletso la lipeipi tsa ho phunya hore le se ke la khojoa le ho senyeha le ho lelefatsa bophelo ba tšebeletso ea DP.

2. E sireletsa manonyeletso a sesebelisoa khahlanong le ho phatloha ha mocheso.

3. E fokotsa ho roala ha casing.

4. E fokotsa tahlehelo ea likhohlano tsa ho cheka.

5. Hardbanding lumella tshebediso ya slim OD welded sesebelisoa manonyeletso.

Lisebelisoa tsa Hardband:

1. Hardband e sebetsa ho phunya liphaephe tsa boholo bohle le limaraka.

2. Hardband e ka sebelisoa ho e ncha le u    sed tubular.

3. Matlapa a thata a ka sebelisoa ho kopanya lisebelisoa tsa liphaephe tsa ho phunya tse entsoeng ka GOST R 54383-2011 le GOST R 50278-92 kapa ka litlhaloso tsa tekheniki tsa lipeipi tsa naha, le ho kopanya lisebelisoa tsa liphaephe tse entsoeng ka API Spec 5DP.

4. Ho ka sebelisoa liphaephe tsa ho phunya liphaephe tse nang le mefuta e sa tšoaneng ea lisebelisoa tsa lisebelisoa, ho kenyelletsa le lisebelisoa tse nang le mahetla a mabeli.

5. Maqhama a thata a ka sebelisoa liphaepheng tsa ho cheka tse sa batang le DP ea tšebeletso ea bolila.

Hardbanding e ka sebelisoa ho tubular ea mefuta le boholo bo latelang:

1. 'Mele oa liphaephe OD 60 ho ea ho 168 mm, bolelele ho fihlela ho 12 m, OD ea lisebelisoa tse entsoeng ka li-welded ka litokomane tsa DP.

2. Hardband e sebelisoa ha HWDP e ferekanngoa, libakeng tse kopanetsoeng tsa lisebelisoa tsa HWDP, le DC tsa mefuta eohle le boholo.

3. Hardbanding e boetse e sebelisoa ho ferekanya bohareng ba HWDP le DC.

4. Li-hardband li ka sebelisoa holim'a manonyeletso a lisebelisoa pele a ka tšeloa phala ea ho phunya.

Poloko e hlahisoang ke tšebeliso ea phala ea ho cheka ka hardbanding:

1. Bophelo ba tšebeletso ea lipeipi tsa ho cheka bo atolosoa ho fihlela makhetlo a 3.

2. Liaparo tse kopantsoeng tsa lisebelisoa li fokotsehile ka 6-15 % ho itšetlehile ka mofuta oa li-hardbanding tse sebelisitsoeng.

3. Liaparo tsa lebota la casing li fokotsehile ka 14-20% ha li bapisoa le ho roala ho bakoang ke lisebelisoa tse hlakileng.

4. E fokotsa tahlehelo ea likhohlano tsa seliba.

5. Torque e hlokahalang ea rotary e fokotsehile, kahoo e fokotsa tšebeliso ea matla.

6. E ntlafatsa ts'ebetso ea ho cheka.

7. E fokotsa nako ea ho phunya.

8. E fokotsa makhetlo a mangata a khoele ea ho cheka le ho hlōleha ha likhoele tsa casing mesebetsing ea ho cheka.
