I-Pup Joint
Ilunga lomdlwane liyikesi noma ishubhu yobude obufushane kuno-Range 1 enoxhumano lwentambo efanayo, esetshenziselwa ukulungisa ubude bezintambo ze-tubular ngokuvumelana nemfuneko yayo ngqo.
Amajoyinti e-Pup akhiqizwa kusuka ku-AISI 4145H noma i-4140H-modified alloy, afakwe ngokushisa abe yi-Brinell Hardness range engu-285-341 enenotshi ye-Charpy “V” yamandla omthelela amancane angu-40 ft/lb ku-70° F kanye ne-intshi eyodwa ngaphansi komhlaba. .Amajoyinti e-Pup aphathwa ngokushisa afinyelele ku-110,000 PSI isivuno esincane.Konke ukuxhuma kuhlanganiswe ne-phosphate ukuze kuvinjwe i-galling ngesikhathi sokuqala sokwenza.
Atholakala ngobude obujwayelekile obungu-5', 10', 15' kanye no-20' nokunye ukulungiselelwa uma kuceliwe.
I-Integral Pup Joints enikezelwe kwizicelo zeSour Service iyatholakala.I-PJ -110 PUP S i-Sour Service Pup Joint esebenzisa impahla ye-ASCOWELL C enikeza ukumelana okuthuthukisiwe ku-Sulfide Stress Cracking enamandla okukhiqiza okuphezulu.
Singahlinzeka ngemikhiqizo yochungechunge olubanzi lokubhoboza nezinsiza nge-API ejwayelekile noma ukusebenza okuphezulu kobunikazi
ukuxhumana ukuze kuhlangatshezwane nezidingo zokumba ezidinga kakhulu.

Okunye ukucupha kuyatholakala uma kuceliwe
Zonke izinketho ze-hardbanding kanye ne-coating ezitholakalayo ngokucela.
I-API Spec 5CT - Leli Zinga licacisa izimo zokulethwa kwezobuchwepheshe zamapayipi ensimbi (i-casing, ishubhu namajoyinti e-pup), isitokwe esihlangene, impahla yokuhlanganisa kanye nesesekeli futhi lisungula izidingo zamaleveli amathathu Okucaciswa Komkhiqizo (PSL-1, PSL-2, PSL- 3).Izimfuneko ze-PSL-1 ziyisisekelo saleli Zinga.Izidingo ezichaza amazinga ahlukene ezimfuneko zobuchwepheshe ezijwayelekile ze-PSL-2 ne-PSL-3, kuwo wonke amabanga ngaphandle kwe-H-40, L-80 9Cr ne-C110, ziqukethwe ku-Annex H.

I-anti-corrosion ye-petroleum casing ihlukaniswe ikakhulukazi ngezinhlobo ezintathu:
- Gcoba i-anti-corrosion coating odongeni olungaphandle.
- Gcoba i-anti-corrosion coating odongeni lwangaphakathi.
- Gcoba okokuvikela ukubola nokupholisa.
Ngokusetshenziswa kwamagobolondo kawoyela kanye nokuhlangana kwe-pup ezimbonini zokukhipha uwoyela ezinonya njenge-polar nezasolwandle.Idinga impahla kanye nesakhiwo se-petroleum pup joint, futhi kufanele ibe nokuvumelana okuhle, izakhiwo ezinhle kakhulu zomzimba, izakhiwo zamakhemikhali ezizinzile, kanye nobubanzi obuhlukahlukene bokujwayela izinga lokushisa.Uma isikhwama samafutha singenziwa, kufanele simbozwe nge-anti-corrosive coating ukuze simsize abhekane nesimo esinzima.Ukufakwa odongeni lwangaphandle kusetshenziselwa ukunciphisa ukugqwala kwangaphandle, futhi okokuvikela ukugqwala odongeni lwangaphakathi ukwehlisa ukungqubuzana, ukunciphisa ukugqwala kwepayipi, nokwandisa inani lamafutha athuthwayo.I-anti-corrosive insulation coating isetshenziselwa ukuthutha uwoyela ongahluziwe namafutha kaphethiloli, nokunciphisa ukushisa okuphuma epayipini kuya emhlabathini.
Indawo yangaphandle izopendiwa (ipandiwe) futhi imakwe ngokwezinga le-API 5CT, ihlanganiswe namakesi okhuni, amaphalethi, amabhande ensimbi noma okunye ukupakisha njengoba kudingwa amakhasimende.
