Pup Joint
A pup joint ikesi kana kuti tubing yehurefu ipfupi pane Range 1 ine shinda yakafanana, inoshandiswa kugadzirisa kureba kwetambo dzetubula kuti dzienderane nezvainoda chaizvo.
Pup Joints inogadzirwa kubva kuAISI 4145H kana 4140H-modified alloy, inopisa-yakagadziriswa kusvika kune Brinell Hardness range ye 285-341 ine Charpy "V" notch shoma inokonzera simba re 40 ft / lb pa 70 ° F uye imwe inch pasi pepamusoro. .Pup Majoini anorapwa kupisa kusvika ku110,000 PSI goho rakaderera.Zvese zvinongedzo zvine phosphate yakavharwa kudzivirira galling panguva yekutanga kugadzira-up.
Iwo anowanikwa muhurefu hwakareba hwe5', 10', 15' uye 20' nemamwe magadzirirwo pakukumbira.
Integral Pup Joints yakatsaurirwa kune Sour Service zvikumbiro zviripo.PJ -110 PUP S vari Sour Service Pup Joint vachishandisa ASCOWELL C zvinhu zvinopa kuvandudzwa kwekudzivirira kuSulfide Stress Kupwanya nesimba regoho guru.
Isu tinokwanisa kupa yakafara dhiza tambo zvigadzirwa uye zvishongedzo zvine yakajairwa API kana proprietary yepamusoro kuita
kubatanidza kusangana nezvinodiwa zvakanyanya zvekuchera.
