Amapayipi ashiselwe ama-Longitudinal
Imikhiqizo Isingeniso
Amapayipi ensimbi ashiselwe iLongitudinal ngokuvamile ahlukaniswa ngokusekelwe ezintweni enziwe ngazo, ukusetshenziswa kwawo okuhlosiwe, kanye namazinga anamathela kuwo. Ngokuvamile, amapayipi ensimbi ashiselwe longitudinal abhekisela kumazinga avamile kanye nezigaba zamapayipi ensimbi angaphansi kwe-Arc Welded.
Amazinga wezinto ezibonakalayo:
Amapayipi ensimbi ashiselwe ngobude angahlukaniswa ngokusekelwe ezintweni ezenziwe ngazo, njenge-carbon steel, insimbi engagqwali, i-alloy steel, njll.
Amazinga okukhiqiza:
Inqubo yokukhiqiza yama-Summerged-Arc Welded Steel Pipes ingalandela izindinganiso ezithile ezibekwe izinhlangano ezifana ne-American Petroleum Institute (API), i-American Society for Testing and Materials (ASTM), noma ezinye izinhlangano zamazinga zikazwelonke noma zamazwe ngamazwe ngale ndlela elandelayo: I-API. 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711,EN10217, EN10219
Inqubo:
I-LSAW – UO(UOE), RB(RBE), JCO(JCOE)
I-DSAW -I-arc engaphansi ephindwe kabili eshiselwe
Ngaphandle Ububanzi: 355.6mm-1626mm
Ubukhulu bodonga: 8 -50mm
Ubude: kufika ku-12m
Ibanga Lensimbi:
I-API 5L: GR B, X42,X46, X56, X60,X65,X70
I-ASTM A53: GR A, GR B, GR C

Ubuso: I-Fusion bond Epoxy coating, Coal Tar Epoxy, 3PE, Vanish Coating, Bitumen Coating, Black Oil coating njengemfuneko yekhasimende ngalinye
Ukuhlolwa: Ukuhlaziywa Kwengxenye Yamakhemikhali, Izakhiwo Zemishini (Amandla Okugcina Aqinile, Amandla Okukhiqiza, Ukwelula), Izakhiwo Zobuchwepheshe (Ukuhlolwa Okuphansi, Ukuhlola Ukugoba, Ukuhlolwa Kwegalelo, Ukuhlolwa Komthelela), Ukuhlolwa Kosayizi Wangaphandle, Ukuhlolwa Kwe-Hydrostatic, Ukuhlolwa Kwe-X-ray.
Isitifiketi Sokuhlola I-Mill: EN 10204/3.1B
Imibandela Yokufaka Isicelo: Amapayipi ashiselwe ngobude angahlukaniswa ngokusekelwe ekusetshenzisweni kwawo okuhlosiwe, njengamapayipi kawoyela negesi, ukufakwa kwesakhiwo, noma ukusetshenziswa kwezimboni okuvamile. Qiniseka ukuthi ubhekisela kumazinga athile kanye nezigaba ezifanele ezidingweni zakho ezithile, njengoba zingahluka ngokuya ngemboni nendawo.
