1. Ukuveliswa kunye neendlela zokuvelisa iipayipi zensimbi ezingenamthungo zingahlulwa zibe yimibhobho eshushu, ibhobho epholileyo, ibhobho epholileyo, ipayipi ekhutshweyo, njl njl ngokweendlela ezahlukeneyo zokuvelisa.

1.1. Imibhobho engenamthungo eshushu eqengqelekayo iveliswa ngokubanzi kwiiyunithi zokuqengqeleka kwemibhobho. I-tube eqinileyo engenanto ihlolwe kwaye iziphene zomhlaba ziyasuswa, zinqunywe ubude obufunekayo, zijoliswe ekupheleni kwe-perforated ye-tube engenanto, kwaye emva koko ithunyelwe kwisithando somlilo sokufudumeza kunye nokubhoboza kumatshini wokubhoboza. Iyaqhubeka ijikeleza kwaye iqhubela phambili ngexesha lokugqobhoza imingxuma. Ngaphantsi kweempembelelo ze-roller kunye nesiphelo, i-tube blank i-hollow ngokuthe ngcembe, ebizwa ngokuba yi-gross pipe. Emva koko ithunyelwa kumatshini wokuqengqeleka kombhobho ukuze uqhubeke uqengqeleka. Ekugqibeleni, ubukhulu bodonga bulinganiswe ngumatshini wokulinganisa, kwaye ububanzi buchongwa ngumatshini wokulinganisa ukuhlangabezana neemfuno ezicacileyo. Ukusetyenziswa kweeyunithi eziqhubekayo zokuqengqeleka kwemibhobho ukuvelisa imibhobho yentsimbi engenamthungo eshushu eqengqelekayo yindlela engaphezulu.

1.2. Ukuba ufuna ukufumana imibhobho engenamthungo enobukhulu obuncinci kunye nomgangatho ongcono, kufuneka usebenzise ukuqengqeleka okubandayo, umzobo obandayo, okanye indibaniselwano yezi zimbini. I-Cold rolling idla ngokuqhutyelwa kwi-mill-roll-roll, kwaye umbhobho wensimbi ugqitywe kwi-annular pass eyakhiwe nge-variable cross-section circular groove kunye nentloko ye-conical esisigxina. Umzobo obandayo udla ngokuqhutywa kwi-0.5 ukuya kwi-100T ye-single-chain okanye i-double-chain ebandayo umatshini wokuzoba.

1.3. Indlela ye-extrusion kukubeka i-tube efudumeleyo engenanto kwi-cylinder evaliweyo ye-extrusion, kwaye intonga ye-perforation kunye nentonga ye-extrusion ihamba kunye ukwenza inxalenye ye-extrusion ikhutshwe kumngxuma omncinci wokufa. Le ndlela inokuvelisa iibhobho zetsimbi ezinamadamitha amancinci.

2. Ukusetyenziswa kwemibhobho yentsimbi engenamthungo

2.1. Imibhobho engenamthungo isetyenziswa ngokubanzi. Imibhobho engenamthungo yenjongo gabalala iqengqeleka ukusuka kwintsimbi yolwakhiwo lwekhabhoni eqhelekileyo, intsimbi yesakhiwo sealloyi ephantsi, okanye intsimbi yolwakhiwo lwealloyi, enemveliso enkulu, kwaye isetyenziswa ikakhulu njengemibhobho okanye iinxalenye zesakhiwo zokuthutha ulwelo.

2.2. Inikezelwa ngokweendidi ezintathu ngokweendlela ezahlukeneyo zokusetyenziswa:

a. Kubonelelwe ngokwemichiza kunye neempawu zoomatshini;

b. Inikezelwe ngokweempawu zoomatshini;

c. Inikezelwe ngokovavanyo loxinzelelo lwe-hydraulic. Ukuba iipayipi zensimbi ezibonelelwe ngokweendidi ze-a kunye ne-b zisetyenziselwa ukujamelana noxinzelelo lwe-liquid, kufuneka kwakhona ziqhube uvavanyo lwe-hydrostatic.

2.3. Imibhobho yenjongo eyodwa engenamthungo ibandakanya imibhobho engenamthungo yeebhoyila, imibhobho engenamthungo yegeology, kunye nemibhobho engenamthungo yepetroleum.

3. Iindidi zemibhobho yentsimbi engenamthungo

3.1. Imibhobho yensimbi engenamthungo inokwahlulwa ibe yimibhobho eshushu, ibhobho eqengqelekayo ebandayo, imibhobho epholileyo, imibhobho ekhutshiweyo, njl.njl ngokweendlela ezahlukeneyo zokuvelisa.

3.2. Ngokwemilo, kukho iityhubhu ezingqukuva kunye nemibhobho ekhethekileyo. Ukongeza kwiityhubhu zesikwere kunye neetyhubhu ezibuxande, iityhubhu ezinokwakheka okukhethekileyo zikwabandakanya iityhubhu ze-oval, iityhubhu zesemi-circular, iityhubhu ezinxantathu, iityhubhu ezinehexagonal, iityhubhu ezimile okweconvex, imibhobho emile okweplam, njl.

3.3. Ngokwezixhobo ezahlukeneyo, zahlulahlulwe kwimibhobho ye-carbon structural, imibhobho ye-alloy ephantsi, imibhobho ye-carbon structural high-quality, i-alloy structural pipes, i-stainless steel pipes, njl.

3.4. Ngokweenjongo ezikhethekileyo, kukho imibhobho yebhoyili, imibhobho ye-geological, iipayipi zeoli, njl.

4. Iinkcukacha kunye nomgangatho wokubonakala kweemibhobho zensimbi ezingenamthungo ziyi-GB/T8162-87.

4.1. Iinkcukacha: I-diameter yangaphandle yombhobho oshushu ngu-32 ~ 630mm. Ubunzima bodonga 2.5 ~ 75mm. Idayamitha yangaphandle yombhobho oqengqelekayo (obandayo otsaliweyo) yi-5 ~ 200mm. Ubunzima bodonga 2.5 ~ 12mm.

4.2. Umgangatho wembonakalo: Umphezulu wangaphakathi nangaphandle wombhobho wentsimbi akufunekanga ube neentanda, ukugotywa, ukugoba, iileya zokwahlula, imigca yeenwele, okanye iziphene zokukrala. Ezi ziphene kufuneka zisuswe ngokupheleleyo, kwaye ubukhulu bodonga kunye nobubanzi bangaphandle akufanele budlule ukuphambuka okungalunganga emva kokususwa.
