Izidingo zokufakwa kwejoyinti le-petroleum casing entambo yokuxhumana kohlobo lokuhlanganisa

1. Ngaphakathi kwamamitha angu-50 ukusuka endaweni yokufaka i-insulation joint, gwema izimbobo ezifile ukuthi zishiselwe.

 

2. Ngemva kokuba i-joint ehlanganisiwe ixhunywe epayipini, akuvunyelwe ukuphakamisa ipayipi phakathi kwamamitha angu-5 ukusuka ekuhlanganyeleni.Ingcindezi kumele ihlolwe kanye nepayipi.

 

3. Ngemuva kokuthi ijoyinti lokufakwa lixhunywe epayipini, ijoyinti kufanele lilungiswe njengoba kudingekile, futhi izinga lokushisa elingaphezulu lejoyinti le-insulation alivunyelwe ukuba libe ngaphezu kuka-120.ngesikhathi sokusebenza kwe-anti-corrosion.

 

4. Uma ufaka i-insulating joint, kufanele ifakwe emaphethelweni amabili ahlangene engxenyeni yepayipi eqondile ngamamitha angu-20 ukusuka endololwaneni futhi usethe ubakaki.Ukufakwa ngaphansi komhlaba kufanele kugwenywe emanzini angapheli.

 

5. Ibanga le-eksisi elimaphakathi lejoyinti kufanele lifakwe kulayini oqondile ofanayo nebanga le-eksisi elimaphakathi lepayipi, futhi amabanga amabili e-eksisi amaphakathi akufanele abe mkhulu kuno-0.2mm ngesikhathi sokufakwa.

 

6 Lapho ukususwa kwepayipiinani lesinxephezelo sejoyinti yokufakelwa, inani lamalunga kufanele linyuswe ukuze lihambisane nokugudluka.Kunqatshelwe ngokuphelele ukulungisa ukubekezelelana okweqile kwepayipi ukuze i-insulation joint ibe sesimweni sokuphazamiseka komkhawulo wokugudluzwa kanye nokuphambuka, ingasaphathwa eyeqile umkhawulo ( Ukwandiswa, ukufuduka, ukuphambuka, njll.).

 

7 Uma ijoyinti le-insulating lisezingeni eliphezulu noma lilenga emoyeni, ipayipi kufanele limiswe ku-hanger, kubakaki, noma kufreyimu yehange.I-insulating joint akufanele ivumele i-joint ukuthi ithwale isisindo kanye ne-axial force yepayipi ngokwayo, ngaphandle kwalokho i-joint kufanele ifakwe idivayisi yokulwa nokudonsa (umthamo wayo wokuthwala).Kumelwe ibe mkhulu kunamandla e-axial wepayipi).
