Pup Joint
Umdibaniso we-pup yi-casing okanye i-tubing yobude obufutshane kunoluhlu lwe-1 kunye noqhagamshelo lwentambo efanayo, esetyenziselwa ukulungisa ubude beentambo ze-tubular kwimfuno yayo kanye.
I-Pup Joints yenziwe ukusuka kwi-AISI 4145H okanye i-4140H-modified alloy, iphathwe ngobushushu ukuya kwi-Brinell Hardness uluhlu lwe-285-341 kunye ne-Charpy "V" yenotshi ye-notch encinci yempembelelo yamandla angama-40 ft / lb kwi-70 ° F kunye ne-intshi enye ngaphantsi komhlaba. .I-Pup Joints iphathwa ubushushu ukuya kwi-110,000 PSI isivuno esincinci.Lonke uqhagamshelo lugqunywe ngefosfati ukuze luthintele ukukrala ngexesha lokwenziwa kokwenziwa.
Zifumaneka kubude obuqhelekileyo be-5', 10', 15' kunye ne-20' kunye nolunye ulungelelwaniso xa uceliwe.
I-Integral Pup Joints enikezelwe kwizicelo zeNkonzo yeSour ziyafumaneka.I-PJ -110 PUP S ziyi-Sour Service Pup Joint usebenzisa i-ASCOWELL C izinto ezibonelela ukuchasana okuphuculweyo kwi-Sulfide Stress Cracking kunye namandla aphezulu esivuno.
Sinokubonelela ngeemveliso zomtya we-drill ezibanzi kunye nezixhobo kunye ne-API eqhelekileyo okanye ukusebenza okuphezulu kobunikazi
uqhagamshelo ukuhlangabezana nezona mfuno zinzima zokomba.

I-anti-corrosion ye-petroleum casing yahlulwe kakhulu ibe ziindidi ezintathu:
- Gcoba i-anti-corrosive coating kudonga olungaphandle.
- Gcoba i-anti-corrosion coating kudonga lwangaphakathi.
- Gcoba into enqanda ukubola kunye nokupholisa.
Ngokusetyenziswa kwe-oyile ye-oyile kunye ne-pup joint kumashishini okukhutshwa kweoli anzima njenge-polar kunye ne-marine.Ifuna imathiriyeli kunye nolwakhiwo lwepetroleum pup joint, kwaye kufuneka ibe nodality elungileyo, iipropathi ezigqwesileyo zomzimba, iipropathi zekhemikhali ezizinzileyo, kunye noluhlu olubanzi lokuziqhelanisa nobushushu.Ukuba i-oyile ye-oyile ayinakwenziwa, kufuneka ifakwe nge-anti-corrosive coating ukumnceda ukuba ajamelane nommandla onzima.Ukugquma eludongeni lwangaphandle kusetyenziselwa ukunciphisa i-corrosion yangaphandle, kunye ne-anti-corrosion coating eludongeni lwangaphakathi kukunciphisa ukukhuhlana, ukunciphisa i-corrosion kumbhobho, kunye nokwandisa umthamo weoli ehanjiswayo.Isigqubuthelo sogqume esichasayo sisetyenziselwa ukuthutha i-oyile ekrwada ne-oyile yamafutha, kunye nokunciphisa ubushushu obuphuma kumbhobho ukuya emhlabeni.
Umphezulu wangaphandle uya kugqunywa (upeyintiwe) kwaye umakishwe ngokwemigangatho ye-API 5CT, ehlanganiswe ngamatyala okhuni, iipaliti, amabhande ensimbi okanye ezinye iipakethi njengoko zifunwa ngabathengi.
