Umbhobho wentsimbi yepetroleum luhlobo lwentsimbi ende enecandelo elinomngxuma kwaye akukho joint ejikelezileyo, ngelixa umbhobho wokuqhekeka kwepetroleum luhlobo lwecandelo loqoqosho lwe-steel.Indima: isetyenziswa kakhulu ekwenzeni iinxalenye zesakhiwo kunye noomatshini, njengombhobho we-oyile, i-automobile drive shaft, isakhelo sebhayisekile kunye nesikafula sentsimbi esisetyenziselwa ukwakhiwa, njl njl. ixesha processing, ezifana ukuqengqeleka isangqa, umkhono jack, njl, sele isetyenziswa ngokubanzi ukuvelisa intsimbi pipe.Petroleum ityhubhu yokuqhekeka okanye iintlobo ngeentlobo zezixhobo eziqhelekileyo eziyimfuneko impahla, umphanda, umgqomo njalo njalo kwi-petroleum yokuqhekeka ityhubhu ukwenza. umjikelezo, ulwelo oluninzi lunokuthuthwa ngombhobho ojikelezayo.

I-API 5CT ihlukaniswe kwi-K55, N80, L80, P110 kunye namanye amabakala ensimbi.

I-Tubing J55 (37Mn5)

I-Casing J55 (37Mn5)

Umbhobho wokudibanisa i-J55 (37Mn5)

Ipayipi yensimbi ye-petroleum (i-GB/T9948-88) yipayipi yensimbi engenamthungo efanelekileyo kwi-tube yesithando somlilo, umtshintshi wokushisa kunye nombhobho kwi-petroleum refinery.

Umbhobho wentsimbi wokomba wejoloji (YB235-70) usetyenziselwa ukugrumba okungundoqo lisebe le-geological, elinokwahlulwa libe ngumbhobho wokubhobhoza, ikhola yokubhola, umbhobho ongundoqo, umbhobho we-casing kunye nombhobho wemvula ngokokusetyenziswa kwayo.
