1.Imibhobho yentsimbi edityanisiweyokuthutho lwe-low-pressure fluid (GB/T3092-1993) ikwabizwa ngokuba yimibhobho edityanisiweyo ngokubanzi, eyaziwa ngokuba yimibhobho emnyama.

Ngumbhobho wentsimbi odityanisiweyo wokuhambisa ulwelo oluphantsi loxinzelelo jikelele olufana namanzi, igesi, umoya, i-oyile kunye nokufudumeza umphunga kunye nezinye iinjongo. Imibhobho yentsimbi yahlulwe ibe yimibhobho yentsimbi eqhelekileyo kunye nemibhobho yentsimbi ejiyileyo ngokobukhulu bodonga; ngokwendlela yeziphelo zombhobho, zihlulwe zibe yimibhobho yentsimbi engafundwanga (imibhobho egudileyo) kunye nemibhobho yensimbi enentambo. Ukucaciswa kombhobho wensimbi kubonakaliswa ngumlinganiselo oqhelekileyo (mm), omalunga nomlinganiselo wangaphakathi. Kuqhelekile ukuchaza ngee-intshi, ezifana ne-11/2. Ukongeza ekusetyenzisweni ngokuthe ngqo ukuthutha ulwelo, imibhobho yentsimbi edityanisiweyo yokuthutha ulwelo olunoxinzelelo oluphantsi nayo isetyenziswa ngokubanzi njengemibhobho yoqobo yemibhobho yentsimbi edityanisiweyo yokuhambisa ulwelo olunoxinzelelo oluphantsi.

2. Umbhobho wentsimbi odityanisiweyo odityanisiweyo wokuthuthwa koxinzelelo oluphantsi (GB/T3091-1993) ukwabizwa ngokuba ngumbhobho wentsimbi owenziwe ngamatye, owaziwa ngokuba ngumbhobho omhlophe.

Imibhobho yentsimbi ediphini eshushu (iziko elidityanisiweyo okanye elidityaniswe ngombane) yokuhambisa amanzi, irhasi, ioyile yomoya, ukufudumeza umphunga, amanzi ashushu kunye nolunye ulwelo oluphantsi loxinzelelo jikelele okanye ezinye iinjongo. Imibhobho yentsimbi yahlulwe ngokwemibhobho yentsimbi eqhelekileyo kunye nemibhobho yentsimbi ejiyileyo ngokobukhulu bodonga; ngokwendlela yeziphelo zemibhobho, zahlulwe zibe yimibhobho yentsimbi engafakwanga ngemisonto kunye nemibhobho yentsimbi enemisonto enemisonto. Ukucaciswa kombhobho wensimbi kubonakaliswa yi-diameter ye-nominal (mm), okuyixabiso eliqikelelweyo le-diameter yangaphakathi.

3. I-carbon steel wire casing eqhelekileyo (i-GB3640-88) yipayipi yensimbi esetyenziselwa ukukhusela iingcingo kwiiprojekthi zokufakelwa kombane ezifana nezakhiwo zoshishino kunye nezoluntu, ukufakwa koomatshini kunye nezixhobo.

4. Umthungo othe ngqo wombane odibeneyo wentsimbi (YB242-63) ngumbhobho wentsimbi kunye ne-weld seam ehambelana nolwalathiso olude lombhobho wensimbi. Ngokwesiqhelo yahlulwe kumbhobho wentsimbi wemetric odityanisiweyo, umbhobho wombane odityanisiweyo obhityileyo, umbhobho weoyile wokupholisa isiguquli njalo njalo.

5.Spiral umthungo entywiliselwe arc welding umbhobho wentsimbiukuthutha ulwelo olucinezelekileyo (SY5036-83) yenziwe ngentsimbi eshushu-eqengqelekayo iikhoyili zentsimbi njengeetyhubhu ezingenanto, ezihlala zibunjwa ngokuvunguza kumaqondo obushushu ashushu, kwaye zidityaniswe ngamacala amabini antywiliselwe i-arc welding. Isetyenziselwa ukuthutha ulwelo olucinezelekileyo. Umbhobho wentsimbi yomthungo ojikelezayo. Umbhobho wentsimbi unamandla okunyamezela uxinzelelo kunye nokusebenza kakuhle kwe-welding. Emva kohlolo olungqongqo lwesayensi kunye novavanyo, kukhuselekile kwaye kuthembekile ukuyisebenzisa. Ububanzi bombhobho wensimbi bukhulu, ukusebenza kakuhle kokuthutha kuphezulu, kwaye utyalo-mali ekubekeni imibhobho lunokugcinwa. Isetyenziswa kakhulu kwimibhobho yokuthutha ioli kunye negesi yendalo.

6. I-Spiral seam ye-high-frequency welded steel pipe yokuthutha ulwelo olucinezelekileyo (SY5038-83) yenziwe nge-coil yentsimbi eshushu eqengqelekayo njengetyhubhu engenanto, ehlala isenziwa ngokujikelezayo kwiqondo lobushushu, kwaye idityaniswe yi-high-frequency lap welding. Isetyenziselwa ukuthutha ulwelo olucinezelekileyo. Spiral umthungo umbhobho wentsimbi ophezulu frequency welding. Umbhobho wentsimbi unamandla okuthwala uxinzelelo kunye neplastiki efanelekileyo, ekulungele ukuwelda kunye nokucutshungulwa. Emva kokuhlolwa okungqongqo kunye nesayensi kunye novavanyo, kukhuselekile kwaye kuthembekile ukuyisebenzisa. Ikakhulu isetyenziselwa ukubeka imibhobho yokuthutha ioli, igesi yendalo, njl.

7. Ngokubanzi, i-spiral seam entywiliselweyo i-arc welded steel pipe (SY5037-83) yokuhambisa ulwelo oluphantsi koxinzelelo lwenziwe ngentsimbi eshushu eqengqelekayo njengetyhubhu engenanto, ehlala ibunjwa ngokujikelezayo, kwaye yenziwe ngamacala amabini azenzekelayo. ukuwelda kwe-arc emanzini okanye ukuwelda kwicala elinye. Imibhobho yentsimbi edityanisiweyo ye-arc ephantsi yoxinzelelo oluphantsi jikelele lokuthuthwa kwamanzi njengamanzi, igesi, umoya kunye nomphunga.

8. I-Spiral seam ye-high-frequency welded welding pipe (SY5039-83) yokuhambisa ulwelo oluphantsi koxinzelelo olusezantsi lwenziwa ngentsimbi eshushu eqengqelekayo njengetyhubhu engenanto, ehlala ibunjwa ngokuvunguza kubushushu obuphezulu, kwaye idityaniswe yi-high-frequency lap welding. ukuhambisa ulwelo olunoxinzelelo oluphantsi jikelele. Umthungo umbhobho wentsimbi odityanisiweyo.

9. Imibhobho yentsimbi edityanisiweyo ye-Spiral yeemfumba (SY5040-83) yenziwe ngeentsimbi ezishushu eziqengqelekayo njengeetyhubhu ezingenanto, ezihlala zisenziwa ngama-spirals afudumeleyo, kwaye zenziwe nge-arc ye-arc enecala eliphindwe kabini okanye i-high-frequency welding. Zisetyenziselwa ulwakhiwo lolwakhiwo loluntu, ii-wharfs, iibhulorho kunye nezinye iimfumba zesiseko ezinemibhobho yentsimbi.
