1. Izindlela zokukhiqiza nezindlela zokukhiqiza zamapayipi ensimbi angenamthungo zingahlukaniswa zibe amapayipi ashisayo, amapayipi abandayo, amapayipi adonswa abandayo, amapayipi akhishwe, njll ngokwezindlela ezahlukene zokukhiqiza.

1.1. Amapayipi angenamthungo agingqika ashisayo ngokuvamile akhiqizwa kumayunithi aginqikayo amapayipi. Ishubhu elingenalutho elingenalutho liyahlolwa futhi amaphutha angaphezulu ayasuswa, anqunywe ubude obudingekayo, agxile ekugcineni kwe-perforated ye-tube engenalutho, bese ithunyelwa esithandweni sokushisa ukuze kushiswe nokubhoboza umshini wokubhoboza. Iyaqhubeka nokujikeleza futhi iqhubekele phambili ngesikhathi sokubhoboza izimbobo. Ngaphansi kwethonya lama-roller kanye nokuphela, i-tube blank ingenalutho kancane kancane, ebizwa ngokuthi i-gross pipe. Bese ithunyelwa emshinini wokugingqa amapayipi ukuze iqhubeke nokugingqika. Ekugcineni, ubukhulu bodonga bulinganiswe ngomshini wokulinganisa, futhi ububanzi bunqunywa umshini wokulinganisa ukuze uhlangabezane nezidingo zokucaciswa. Ukusetshenziswa kwamayunithi okugingqa amapayipi aqhubekayo ukuze kukhiqizwe amapayipi ensimbi angenamthungo ashisayo kuyindlela ethuthuke kakhulu.

1.2. Uma ufuna ukuthola amapayipi angenamthungo anamasayizi amancane kanye nekhwalithi engcono, kufanele usebenzise ukugoqa okubandayo, umdwebo obandayo, noma inhlanganisela yakho kokubili. Ukugoqa okubandayo kuvame ukwenziwa emshinini onama-roll amabili, futhi ipayipi lensimbi ligoqeka ku-annular pass elakhiwe nge-variable cross-section groove eyindilinga kanye nekhanda le-conical elingaguquki. Umdwebo obandayo ngokuvamile wenziwa ku-0.5 kuya ku-100T we-single-chain noma umshini wokudweba obandayo we-double-chain.

1.3. Indlela ye-extrusion ukubeka ishubhu elishisayo lingenalutho kusilinda esivaliwe se-extrusion, futhi induku yokubhoboza kanye nenduku ye-extrusion ihamba ndawonye ukuze yenze ingxenye ye-extrusion ikhishwe emgodini omncane wokufa. Le ndlela ingakhiqiza amapayipi ensimbi anama-diameter amancane.

2. Ukusetshenziswa kwamapayipi ensimbi angenamthungo

2.1. Amapayipi angenamthungo asetshenziswa kakhulu. Amapayipi angenamthungo anenjongo evamile asongwa kusukela kunsimbi evamile ye-carbon structural, insimbi yesakhiwo sengxubevange ephansi, noma insimbi yesakhiwo sengxubevange, enomphumela omkhulu kakhulu, futhi asetshenziswa kakhulu njengamapayipi noma izingxenye zesakhiwo zokuthutha uketshezi.

2.2. Ihlinzekwa ngezigaba ezintathu ngokuya ngokusetshenziswa okuhlukene:

a. Ihlinzekwe ngokwamakhemikhali kanye nezakhiwo zemishini;

b. Ihlinzekwe ngokwezakhiwo zemishini;

c. Ihlinzekwa ngokuya ngokuhlolwa kwengcindezi ye-hydraulic. Uma amapayipi ensimbi ahlinzekwe ngokwezigaba u-a no-b esetshenziselwa ukumelana nokucindezela koketshezi, kufanele futhi ahlolwe i-hydrostatic.

2.3. Amapayipi anezinjongo ezikhethekile ahlanganisa amapayipi angenamthungo wamabhayela, amapayipi angenamthungo we-geology, namapayipi angenamthungo e-petroleum.

3. Izinhlobo zamapayipi ensimbi angenamthungo

3.1. Amapayipi ensimbi angenamthungo angahlukaniswa abe amapayipi ashisayo, amapayipi abandayo, amapayipi adonswa ngamakhaza, amapayipi akhishwe, njll ngokwezindlela ezahlukene zokukhiqiza.

3.2. Ngokusho komumo, kunamashubhu ayindilinga namashubhu amise okukhethekile. Ngaphezu kwamashubhu ayisikwele namashubhu angama-rectangular, amashubhu amise okwesipesheli ahlanganisa namashubhu ayisiyingi, amashubhu ayindilinga, amashubhu angunxantathu, amashubhu angama-hexagonal, amashubhu amise okwe-convex, amashubhu amise okweplamu, njll.

3.3. Ngokwezinto ezahlukahlukene, zihlukaniswe ngamapayipi ajwayelekile e-carbon structural, amapayipi esakhiwo se-alloy aphansi, amapayipi e-carbon structural esezingeni eliphakeme, amapayipi esakhiwo se-alloy, amapayipi ensimbi engagqwali, njll.

3.4. Ngokwezinjongo ezikhethekile, kukhona amapayipi e-boiler, amapayipi e-geological, amapayipi kawoyela, njll.

4. Ukucaciswa kanye nekhwalithi yokubukeka kwamapayipi ensimbi angenamthungo nge-GB/T8162-87.

4.1. Imininingwane: Ububanzi bangaphandle bepayipi eligoqelwe ngokushisayo ngu-32~630mm. Ubukhulu bodonga 2.5 ~ 75mm. Ububanzi bangaphandle bepayipi eligoqiwe (elibandayo elidonswe) lingu-5 ~ 200mm. Ubukhulu bodonga 2.5 ~ 12mm.

4.2. Ikhwalithi yokubukeka: Indawo yangaphakathi nengaphandle yepayipi lensimbi akumele ibe nemifantu, ukugoqeka, ukugoqa, izendlalelo zokuhlukanisa, imigqa yezinwele, noma amanxeba okulimaza. Lezi ziphambeko kufanele zisuswe ngokuphelele, futhi ubukhulu bodonga kanye nobubanzi bangaphandle akufanele budlule ukuphambuka okungalungile ngemva kokususwa.

4.3. Zombili iziphetho zepayipi lensimbi kufanele zisikwe ngama-engeli angakwesokudla futhi ama-burrs kufanele akhishwe. Amapayipi ensimbi anogqinsi olungaphezulu kuka-20mm avunyelwe ukusikwa ngokusika igesi nokusaha okushisayo. Kungenzeka futhi ukuthi unganqamuli ikhanda ngemuva kwesivumelwano phakathi kwabahlinzeki kanye nabafunayo.

4.4. “Ikhwalithi engaphezulu” yamapayipi ensimbi adonswa ngokubanda noma agingqike ngokunemba asho i-GB3639-83.

5. Ukuhlolwa kokwakheka kwamakhemikhali kwamapayipi ensimbi angenamthungo

5.1. Ukwakheka kwamakhemikhali kwamapayipi asekhaya angenamthungo ahlinzekwa ngokuya ngokwakheka kwamakhemikhali kanye nezakhiwo zemishini, njengeNo. 10, 15, 20, 25, 30, 35, 40, 45, kanye nensimbi engu-50, kuzohambisana nezinhlinzeko ze-GB/T699- 88. Amapayipi angenamthungo angenisiwe ahlolwa ngokuvumelana nezindinganiso ezifanele ezishiwo kwinkontileka. Ukwakheka kwamakhemikhali kwensimbi engu-09MnV, 16Mn, kanye ne-15MnV kufanele kuthobelane nemithethonqubo ye-GB1591-79.

5.2. Ukuze uthole izindlela ezithile zokuhlaziya, sicela ubhekisele ezingxenyeni ezifanele ze-GB223-84 “Izindlela Zokuhlaziya Amakhemikhali Zensimbi Nezingxubevange”.

5.3. Ukuze uthole ukuchezuka kokuhlaziya, bheka ku-GB222-84 ”Ukuchezuka okuvumelekile kokwakheka kwamakhemikhali kwamasampuli nemikhiqizo eqediwe ukuze kuhlaziywe amakhemikhali ensimbi”.
