API 5Lumbhobho wentsimbi ongenamthungo ngumbhobho wentsimbi ongenamthungo wentsimbi yombhobho--I-API 5L ipayipi yentsimbi engenamthungoyentsimbi yombhobho, umbhobho wentsimbi ongenamthungo, imathiriyeli yentsimbi yombhobho: GR.B, X42, X46, 52, X56, X60, X65, X70. Umbhobho wepayipi usetyenziselwa ukuthutha i-oyile, irhasi kunye namanzi atsalwa phantsi emhlabeni ukuya kumashishini oshishino lwe-oyile negesi ngemibhobho. Imibhobho yepayipi ibandakanya imibhobho engenamthungo kunye nemibhobho yentsimbi edityanisiweyo, kwaye iziphelo zemibhobho yazo zineziphelo ezisicaba, iziphelo ezinemisonto kunye neziphelo zesokethi; iindlela zabo zokudibanisa i-welding, i-coupling connection, uxhumano lwe-socket, njl.
I-API 5L yentsimbi yombhobho, umgangatho: API5L ASTM ASME B36.10. I-DIN. Uluhlu lwedayamitha yangaphandle 13.7mm-1219.8mm, ububanzi bodonga 2.11mm-100mm.
Ubude: 5.8m, 6m, 11.6m, 11.8m, 12m ubude obuzinzileyo
Ukupakishwa: ukupeyinta ukutshiza, i-bevel, ikepusi yombhobho, ukubopha umtya wentsimbi, umtya wokuphakamisa omthubi, ukupakishwa kwengxowa elukiweyo iyonke.
1. Iimpawu ze-API 5LX42 ipayipi yentsimbi engenamthungo

API 5LX42umbhobho wensimbi ongenamthungo ngumbhobho wensimbi ophezulu, ophantsi kwe-alloy kunye namandla esivuno se-420MPa kunye nokuqina okulungileyo kunye nokuxhathisa ukubola. Umbhobho wensimbi wenziwa ngokusetyenziswa kwenkqubo engenamthungo, enodonga lwangaphakathi olugudileyo, akulula ukuqokelela ukungcola, kwaye kulula ukuyicoca nokugcina. Ukongeza, i-API 5LX42 ipayipi yensimbi engenamthungo nayo ine-weldability efanelekileyo kunye nokuchasana nokuqhekeka kwe-hydrogen-induced cracking, enokuthi ihlangabezane neemfuno zokusetyenziswa kwiindawo ezinzima.

2. Ukusetyenziswa kwe-API 5LX42 ipayipi yensimbi engenamthungo

I-API 5LX42 ipayipi yensimbi engenamthungo isetyenziswa kakhulu kwimibhobho yeoli kunye negesi, iindawo zokucoca, izityalo zekhemikhali kunye nezinye iindawo. Ngokumalunga nokuthuthwa kweoli kunye negesi, i-API 5LX42 imibhobho yensimbi engenamthungo inokumelana neendawo ezinobungozi ezifana noxinzelelo oluphezulu, ubushushu obuphezulu kunye ne-corrosion ukuqinisekisa ukuthuthwa okukhuselekileyo kweoli kunye negesi. Kwiindawo zokucoca kunye nezityalo zekhemikhali, i-API 5LX42 imibhobho yentsimbi engenamthungo isetyenziselwa ukuthutha imidiya eyahlukeneyo eyingozi, efana ne-sulfuric acid kunye ne-hydrochloric acid.

3. Inkqubo yokuvelisa i-API 5LX42 imibhobho yentsimbi engenamthungo

Inkqubo yokuvelisa i-API 5LX42 imibhobho yensimbi engenamthungo ikakhulu ibandakanya ukulungiswa kwetyhubhu engenanto, ukugqobhoza, ukuqengqeleka, unyango lobushushu, ukulungiswa, ukuhlolwa kunye nokupakishwa. Phakathi kwabo, ukulungiswa kwe-tube blank enye yekhonkco eziphambili, kwaye izinto ezisemgangathweni eziphezulu kufuneka zikhethwe kwaye zihlolwe ngokungqongqo kwaye zilawulwe. Ngethuba lenkqubo yokubhobhoza kunye nokuqengqeleka, iiparitha ezifana nobushushu, isantya kunye noxinzelelo kufuneka zilawulwe ukuze kuqinisekiswe ukuba ubukhulu bodonga, ububanzi kunye nomgangatho womphezulu wombhobho wensimbi uhlangabezana neemfuno. Ikhonkco lonyango lobushushu lilawula iiparitha ezifana nobushushu bokufudumala, ixesha lokugquma kunye nesantya sokupholisa ukwenzela ukuba umbhobho wensimbi ufumane intlangano kunye nokusebenza kakuhle. Ekugqibeleni, umbhobho wensimbi kufuneka uhlolwe ngokungqongqo kunye nokuvavanya ukuqinisekisa ukuba umgangatho wayo uhlangabezana neemfuno eziqhelekileyo.
