API 5CT Blast Joint Yekupedzisa Pipe String

Iyo Blast Joint chinhu chakakosha mukushanda kweoiri uye gasi, chakagadzirirwa kupa dziviriro kune tubing tambo uye kuderedza kukonzeresa kwekunze kubva kumvura inoyerera.Iyo inovakwa uchishandisa simbi yemhando yepamusoro ine nhanho yekuomarara kubva pa28 kusvika 36 HRC maererano neNACE MR-0175.
Izvi zvinovimbisa kugara kwayo uye kutendeseka mumamiriro ezvinhu akaoma.

Nekuisa zvine hungwaru kuputika kwejoint yakatarisana netsime perforations kana pazasi petubhing hanger panguva yekutsemuka kwejecha, inopa imwezve yekudzivirira kune tubing tambo.Iyo blast joint's heavy-walled tubing kuvaka inodzivirira kubva kune erosive simba uye inodzivirira kukuvadzwa kwemidziyo yekugadzira.

Kuti uchengetedze yakazara-yakazara mukati medhayamita yehubhu, kuputika kwekubatana kwakagadzirwa kuti ive nehupamhi hwekunze hwakafanana sezvibatanidzwa zvakabatanidzwa nazvo.Izvi zvinobvumira kuyerera kwemvura yakatsetseka kuburikidza nehurongwa pasina zvirambidzo zvakakosha.

Mumamiriro ezvinhu apo kuvepo kwehydrogen sulfide (H2S) kuri kunetseka, Landrill inokwanisa kugadzira majoini ekuputika akagadzirirwa masevhisi eH2S.Aya majoini ekuputika anogadzirwa kubva kune zvinopiswa-kupisa zvine mwero wekuomarara pakati pe18 ne22 HRC zvichienderana nezvakatsanangurwa muNACE MR-0175.Kuomerera kune aya zviyero kunovimbisa kuramba kwejoint kune corrosive mhedzisiro yeH2S uye inochengetedza kuvimbika kwese kwetambo yechubhu munzvimbo dzakapfuma dzeH2S.

Pakazere, iyo blast joint chinhu chakakosha mukupedzisa kwematsime uye mashandiro ekugadzira, ichipa dziviriro uye hupenyu hurefu kune tubing tambo uchichengeta yakakwana yekuyerera maitiro.
