Ipayipi elishiselwe, elaziwa nangokuthi ipayipi lensimbi elishiselwe, ngokuyisisekelo lenziwa ngepuleti lensimbi noma umucu oshiselwe ngemva kokubola nokwakheka.Ipayipi lensimbi elishiselwe linezinzuzo zenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izinhlobo eziningi kanye nokucaciswa, kanye nokutshalwa kwezimali kwemishini encane, kodwa amandla ayo ajwayelekile aphansi kunalawo epayipi lensimbi engenamthungo.Kusukela ngawo-1930, ngokuthuthuka okusheshayo kokukhiqizwa kwekhwalithi ephezulu yokugoqa kanye nenqubekelaphambili yobuchwepheshe bokushisela kanye nobuchwepheshe bokuhlola, ikhwalithi ye-welded seam ibilokhu ithuthukiswa ngokuqhubekayo, izinhlobonhlobo kanye nokucaciswa kwepayipi lensimbi elishiselwe kuye kwanda, nensimbi engenamthungo. ipayipi selishintshiwe ezindaweni eziningi.Amapayipi ensimbi ashiselwe ahlukaniswe abe ipayipi eliqondile lomthungo elihlanganisiwe kanye nepayipi elihlanganisiwe elivunguzayo ngokusho kwefomu lokushisela.

eyodwa.Ukwahlukaniswa kwamapayipi ashiselwe Amashubhu ashiselwe

Amapayipi ashiselwe ahlukaniswa ngokusetshenziswa kwawo: futhi ahlukaniswa ngamapayipi ashiselwe ajwayelekile, amapayipi ashiselwe afaka i-galvanizing, amapayipi ashiselwe umoya-mpilo, imikhono yocingo, amapayipi ashiselwe we-metric, amapayipi angasebenzi, amapayipi epompo ajulile, amapayipi emoto, amapayipi e-transformer, ashiselwe azacile. -amapayipi anezindonga, amapayipi ashiselwe angajwayelekile kanye namapayipi ashiselwe athandelene.

ezimbili.Uhla Lokusebenza Lwepayipi Elishiselwe

Imikhiqizo yamapayipi ashiselwe isetshenziswa kabanzi kubhayela, imoto, ukwakha umkhumbi, ukwakha iminyango yesakhiwo esinesisindo esincane namafasitela ensimbi, ifenisha, imishini ehlukahlukene yezolimo, i-scaffolding, ipayipi yokufaka intambo, amashalofu aphezulu, izitsha nokunye ingahlangabezana nezidingo zekhasimende, ipayipi elikhethekile elishiselwe okungavamile lingakhiqizwa ngokuvumelana nezidingo zomsebenzisi.

ezintathu.INDLELA YOKUBALA YOMBONGO YESISINDO SEPHIPHI ESHISHISELWE  

Kunamafomula okubala isisindo sepayipi elishiselwe.

Isisindo sethiyori imitha ngayinye yepayipi lensimbi (ukuminyana kwensimbi ngu-7.85 kg/dm3)

Ifomula: W = 0.02466 (DS)S

Kufomula yokubala, isisindo sethiyori sepayipi le-W-steel imitha, kg/m;

D - I-diameter yangaphandle ebizwa ngokuthi ipayipi yensimbi, mm;

S - ukushuba odongeni lwensimbi, mm.

Ezine.Incazelo Esemthethweni Nokusetshenziswa Kwezimboni Kwepayipi Elishiselwe

Izinto zokusetshenziswa ezisetshenziswa esigayweni esishiselwe ishubhu ipuleti lensimbi noma umucu wensimbi.Ingahlukaniswa ipayipi elishiselwe esithandweni somlilo, ipayipi elihlanganisiwe likagesi kanye nepayipi elizenzakalelayo le-arc elishiselwe ngenxa yobuchwepheshe obuhlukene bokushisela.Ngokusho kwamafomu e-welding ahlukene, ingahlukaniswa ibe ipayipi eliqondile lomthungo elihlanganisiwe kanye ne-spiral welded pipe.per ukuma kokuphela, ingahlukaniswa ibe yipayipi elihlanganisiwe eliyindilinga kanye nepayipi elihlanganisiwe elikhethekile (ipayipi eliyisikwele eliyisikwele njll.) .Amapayipi ashiselwe angahlukaniswa abe yizigaba ezilandelayo ngokwezinto zawo ezihlukene kanye nokusetshenziswa kwawo:

1. GB/T3091-1993 (Iphayiphi Lensimbi Elishiselwe I-Galvanized for Low Pressure Fluid Conveyance)

2. GB/T3092-1993 (Ipayipi Lensimbi Elishiselwe Ikhalvanized Yokudluliswa Koketshezi Lokucindezela Okuphansi)

Isetshenziselwa kakhulu ukudlulisa amanzi, igesi, umoya, uwoyela, ukushisisa amanzi ashisayo noma isitimu kanye nolunye uketshezi olujwayelekile olunomfutho ophansi kanye namanye amapayipi enhloso.Izinto zayo ezimele yinsimbi yezinga le-Q235A.

3. GB/T 14291-1992 (Ipayipi Elishiselwe Lezokuthutha Ezimanzi Ezimayini)

Isetshenziselwa kakhulu ukucindezela komoya emayini, i-drainage, i-drainage yegesi ye-shaft enepayipi lensimbi elinomthungo oqondile.Izinto zayo ezimele ziyi-grade Q235A nensimbi engu-B.I-GB/T 14980-1994 (Ipayipi Lensimbi Elishiselwe Ububanzi Elikhulu Lokudluliswa Kwe-Fluid Yengcindezi Ephansi).Isetshenziselwa kakhulu ukudlulisa uketshezi olunomfutho ophansi njengamanzi, indle, igesi, umoya, ukushisa isitimu nezinye izinjongo.Izinto zayo ezimele ziyinsimbi yezinga Q235A.

4. GB/T12770-1991 (Ipayipi elishiselwe lensimbi engagqwali lokwakhiwa komshini)

Isetshenziselwa kakhulu imishini, izimoto, amabhayisikili, ifenisha, ukuhlobisa kwehhotela nehhotela nezinye izingxenye zemishini nezingxenye zesakhiwo.Izinto zayo ezimele ziyi-0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, njll.

I-GB/T12771-1991 (Ipayipi Lensimbi Engenasici Elishiselwe Yezokuthutha Eziwuketshezi)

Isetshenziselwa kakhulu ukudlulisa imidiya elimazayo enengcindezi ephansi.

Izinto ezisetshenziswayo ezimele i-0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, njll.
