Ipayipi Lensimbi Lokunamathela Elisezingeni Eliphezulu
Ipayipi Lensimbi Lokunamathela Elisezingeni Eliphezulu
(1) Inqubo yokukhiqiza ipayipi lensimbi engenamthungo ingahlukaniswa ngezigaba ezimbalwa eziyisisekelo: i-hot rolling (extrusion), i-cold rolling (umdwebo) kanye nepayipi lensimbi elishisayo elinwetshiwe.
(2) Ngokwenqubo yokukhiqiza, ipayipi elishiselwe lingahlukaniswa libe ipayipi lensimbi elinomthungo oqondile, ipayipi lensimbi elivunguzayo, ipayipi le-coil butt elishiselwe ipayipi lensimbi kanye nepayipi elishiselwe ipayipi lensimbi elishisayo.
Ngokwesimo, amapayipi ensimbi angahlukaniswa: ipayipi eliyindilinga, ipayipi lesikwele, ipayipi elingunxande, i-octagonal, i-hexagonal, i-D-shaped, i-pentagonal namanye amapayipi ensimbi amise okwesipesheli, amapayipi ensimbi esigaba esiyinkimbinkimbi, amapayipi ensimbi aphindwe kabili, amapayipi amahlanu. amapayipi ensimbi e-quincunx, amapayipi ensimbi ayi-conical, amapayipi ensimbi kathayela, amapayipi ensimbi embewu yekhabe, amapayipi ensimbi ayi-convex aphindwe kabili, njll.
Ipayipi lensimbi lingahlukaniswa: ipayipi lensimbi lepayipi, ipayipi lensimbi lemishini eshisayo, ipayipi yensimbi yemboni yemishini, ipayipi yensimbi ye-petroleum kanye ne-geological drilling, ipayipi lensimbi yesitsha, ipayipi lensimbi lemboni yamakhemikhali, ipayipi lensimbi ngenjongo ekhethekile, njll. Ukuhlukaniswa kwe-Anti corrosion yodonga lwangaphakathi: ukugoqa okugoqiwe kwe-epoxy kwe-ipn8710 anti-corrosion kanye nokuhlanganisa ukugoqa okuhlanganiswe ne-epoxy powder anti-corrosion.
Ukuhlukaniswa kodonga lwangaphandle olulwa nokugqwala: ukugoqa i-2PE / 3PE anti-corrosion, ungqimba olulodwa lwe-PE anti-corrosion kanye nokugoqa i-epoxy coal asphalt anti-corrosion.I-anti corrosion standard: I-FBE epoxy powder elwa nokugqwala kufanele ihambisane ne-SY / t0315-2005 imininingwane yobuchwepheshe yokuhlanganiswa kongqimba olulodwa okuhlanganiswe i-epoxy powder yangaphandle yepayipi lensimbi, i-2PE / 3PE anti-corrosion izohambisana ne-GB / t23257-2009 indinganiso yobuchwepheshe i-polyethylene yangaphandle yepayipi yensimbi engcwatshwe, izinga lokususa ukugqwala kwe-anti-corrosion surface: ukuqhunyiswa kwesihlabathi endaweni engaphandle yepayipi lensimbi kuzofinyelela ku-SA2 1 / 2 ngokwezidingo ze-GB / t8923-2008, kanye nokujula kokusanhlamvu kwehange ku- ubuso bepayipi lensimbi kufanele libe ngu-40-100 μ m.
Izinto eziyisisekelo zamapayipi ensimbi elwa nokugqwala zihlanganisa amapayipi asongezelayo, amapayipi omthungo aqondile, amapayipi angenamthungo, njll. e-China, asetshenziswa kakhulu emikhakheni yobunjiniyela bamapayipi njengokudluliswa kwamanzi amabanga amade, i-petroleum, imboni yamakhemikhali, igesi yemvelo, ukushisa. , ukuhlanzwa kwendle, umthombo wamanzi, ibhuloho, isakhiwo sensimbi, ukuhanjiswa kwamanzi olwandle kanye nokunqwabelanisa.
Ngaphezu kokuthuthukisa impilo yesevisi yepayipi lensimbi ngokusebenzisa i-anti-corrosion, kubonakala futhi kulezi zici ezilandelayo:
1. Hlanganisa amandla omshini wepayipi lensimbi nokumelana nokugqwala kwepulasitiki;
2. Udonga lwangaphandle lungaphezu kuka-2.5mm, alukwazi ukuklwejwa nokushayisana;
3. I-coefficient ye-friction yodonga lwangaphakathi incane, i-0.0081-0.091, inciphisa ukusetshenziswa kwamandla;
4. Udonga lwangaphakathi luhlangabezana namazinga ezempilo kazwelonke;
5. Udonga lwangaphakathi lubushelelezi futhi akulula ukukala, lunomsebenzi wokuzihlanza.
