Ngokuqondile eziqhutshwa spiral steel abakhiqizi amapayipi ezindaweni zokwakha
Amazinga ajwayelekile epayipi lensimbi elivunguzayo ngokuvamile ahlukaniswe abe: SY / t5037-2008 (izinga likangqongqoshe, elaziwa nangokuthi ipayipi lensimbi elihlanganisiwe le-arc elishiselwe ipayipi elijwayelekile lokudlulisa uketshezi), i-GB / t9711.1-2008 (izinga likazwelonke, elaziwa nangokuthi njengezimo zobuchwepheshe zokulethwa kwepayipi lensimbi lokudlulisa embonini kawoyela negesi, ingxenye I: isigaba sepayipi lensimbi (ipayipi lensimbi le-GB / t9711.2 lesigaba B elinezidingo eziqinile)), i-api-5l (i-American Petroleum Association, eyaziwa nangokuthi insimbi yamapayipi ipayipi); Kubandakanya i-PSL1 ne-PSL2), i-SY / t5040-2008 (ipayipi lensimbi elivunguzayo lenqwaba).
I-SY / t5037-2008 iyindinganiso ebekwe i-Ministry of petroleum, ngokuvamile ebizwa ngokuthi izinga lenkonzo.
I-GB / t9711.1-2008 ipayipi elivunguzayo likazwelonke, ipayipi lensimbi lokudlulisela lemboni ye-petroleum negesi yemvelo, isigaba A.
Ipayipi lensimbi elishiselwe i-Spiral seam high-frequency welded (sy5039-2000) yokuthutha uketshezi olunengcindezi ephansi ithatha ikhoyili yensimbi egoqelwe eshisayo njengepayipi elingenalutho, ngokuvamile ukwakheka kwe-spiral efudumele, futhi isebenzisa indlela yokushisela i-high-frequency lap ukushisela umthungo ovunguzayo phezulu- i-frequency welded steel pipe yokuthutha uketshezi olunengcindezi ephansi.
Ipayipi lensimbi elishiselwe ku-Spiral lenqwaba (sy5040-2000) lenziwe ngekhoyili yensimbi egoqelwe eshisayo njengepayipi elingenalutho, ngokuvamile ukwakheka kwe-spiral efudumele, ukushisela okungaphansi kwe-arc okunezinhlangothi ezimbili noma i-high-frequency welding. Isetshenziselwa ipayipi lensimbi isisekelo inqwaba isakhiwo civil building, wharf, ibhuloho nokunye. Ukuze kuthuthwe uketshezi olucindezelwe, kusetshenziswa ipayipi lensimbi eli-spiral elingaphansi kwe-arc elishiselwe i-sy5036-2000, elisetshenziselwa ikakhulukazi amapayipi athutha uwoyela negesi yemvelo;
I-Spiral seam high-frequency welded steel pipe sy5038-2000 yokudlulisa uketshezi olucindezelayo, olushiselwa ngendlela ye-high-frequency lap welding futhi isetshenziselwe ukudluliswa koketshezi olucindezelayo. Ipayipi lensimbi linomthamo oqinile wokuthwala ingcindezi kanye nepulasitiki enhle, elungele ukushisela nokucubungula;
Ukuthutha okujwayelekile koketshezi olunomfutho ophansi, kusetshenziswa ipayipi lensimbi eliyi-arc welded steel sy5037-2000 elivalekile, kanye nepayipi lensimbi elishiselwe i-arc elishiselwe ukuthutha uketshezi olunengcindezi ephansi njengamanzi, igesi, umoya nesitimu kwenziwa ngokuzenzakalelayo okunezinhlangothi ezimbili. ukushisela i-arc ngaphansi kwamanzi noma ukushisela ohlangothini olulodwa.
