Izindaba - Ubukhulu Bepayipi Lensimbi Obuqoshwe: Ishejuli, Ubukhulu Bodonga kanye Neshadi Losayizi

Esinye sezici ezididayo kakhulu lapho uthenga amapayipi ensimbi uhlelo lokulinganisa – i-OD, ukujiya kodonga, usayizi ojwayelekile, Isheduli… uhlu luyaqhubeka. Imininingwane engalungile ingalibazisa iphrojekthi yakho noma ibangele ukwehluleka endaweni.

At Iqembu Lensimbi Yasebukhosini, sihlanganise lo mhlahlandlela osheshayo wokubhekisela ngokusekelwe eminyakeni yolwazi lokuphakelwa komhlaba wonke. Uhlanganisa izinto ezibalulekile ukuze ukwazi ukucacisa amapayipi ngendlela efanele nangokuzethemba.

Amapharamitha Amathathu Ayisihluthulelo Epayipi Lensimbi

Noma yiliphi ipayipi lingachazwa ngezinombolo ezintathu kuphela:

Ububanzi Bangaphandle (OD)– ububanzi bangaphandle bepayipi

Ubukhulu Bodonga (WT)– ukuthi udonga lwepayipi lubanzi kangakanani

Ubude– ngokuvamile amamitha angu-6 (20 ft) noma angu-12 (40 ft)

Ngalezi, ungakwazi ukubala isisindo, umthamo wokucindezela, kanye nezindleko ngemitha noma ngonyawo.

Ishadi Lobukhulu Bepayipi Lensimbi (Ishadi Losayizi)

Iyunithi Yeshadi Leshejuli Yamapayipi ngo-mm njengoba kuboniswe ngezansi, buka lapha ukuze uthole Ishadi Leshejuli Yamapayipi ngo-intshi.

Izindinganiso Zemboni Zosayizi Wepayipi

Kusetshenziswa amazinga amabili ayinhloko emhlabeni jikelele:

I-ASME B36.10M- ihlanganisa ubukhulu bamapayipi angenamthungo nashibilikisiwe ensimbi yekhabhoni nensimbi ye-alloy, ukuze kube nensizakalo evamile, yokucindezela okuphezulu, kanye neyokushisa okuphezulu

I-ASME B36.19M– ihlanganisa ubukhulu bepayipi lensimbi engagqwali; ikakhulukazi ifana ne-B36.10M, kodwa ezinye izingqimba zodonga zimakwe ngesijobelelo esithi "S" ukuze zihlukaniswe

Osayizi Abaqanjiwe: i-NPS ne-DN

I-NPS (Usayizi Wepayipi Elijwayelekile)– igama elivamile laseNyakatho Melika, ngamasentimitha.

Ugibe oluvamile:I-NPS AKUSIYONA i-OD yangempela.Kumasayizi angaphansi kwe-NPS 12 (DN 300), i-OD yangempela inkulu kunenombolo ejwayelekile. Isibonelo, ipayipi le-NPS 4 line-OD yangempela engama-intshi angu-4.5, hhayi ama-intshi angu-4.

I-DN (Ububanzi Obufanele)– isilinganiso se-metric esisetshenziswa emhlabeni jikelele, ngamamilimitha. Inani le-DN liseduze, kodwa hhayi ngqo, nobubanzi bangaphakathi. Liqinisekisa ukuthi amapayipi kanye nezinto zokufaka ezine-DN efanayo ziyashintshana.

Ukuguqulwa phakathi kwe-NPS ne-DN:I-DN25 = NPS 1, DN50 = NPS 2, njalo njalo.

Izinombolo Zeshejuli – "Ibanga" Lobukhulu Bodonga

Ishejuli (efingqiwe njenge-Sch)inombolo emele uchungechunge lokujiya kodonga – hhayi inani lokujiya elihleliwe.

Ngosayizi onqunyiwe, lapho inombolo yeShejuli iphakama, udonga luba lukhulu futhi isilinganiso sokucindezela siphezulu. Amashejuli avamile afaka phakathi i-Sch 5, 10, 20, 30, 40, 80, 120, kanye ne-160.

Kungani i-Sch 40 ne-Sch 80 zithandwa kangaka?Ngoba zimboza ubukhulu bodonga obudingekayo eningini lezicelo zezimboni. Zitholakala kokubili ngensimbi yekhabhoni (isb., API 5L, ASTM A106B) kanye nensimbi engagqwali (isb., ASTM A312 316L), ngakho-ke ziyizinto ezisetshenziswa kakhulu futhi ezisetshenziswa kakhulu.

Amakilasi Esisindo (i-WGT)

Ngaphambi kokuba uhlelo lweShejuli lube olujwayelekile, ubukhulu bodonga babuhlukaniswa ngesisindo:

I-STD (Ejwayelekile)

I-XS (Eqinile Kakhulu)

I-XXS (I-Double Extra Strong)

Lezi zigaba zomlando zihambisana nezinombolo ezithile zeShejuli - ukuze uthole okulingana okuqondile, bheka i-ASME B36.10 kanye ne-B36.19.

Indlela Yokuchaza Ngokufanele Imininingwane Yepayipi

Noma iyiphi yalezi zindlela ezilandelayo iyamukeleka, kuye ngokuthi ukhetha ini noma ukuthi umkhuba wakho wesifunda unjani:

Ifomethi	Isibonelo
OD × Ubukhulu Bodonga × Ubude	Φ88.9mm × 5.49mm × 6m
I-NPS × Isheduli	I-NPS 3″ × I-Sch 40
I-NPS × Isigaba Sesisindo	I-NPS 3″ × STD
OD × Isisindo Ngeyunithi Ubude	3½″ × 16.8 lb/ft

Iqembu Lensimbi Yasebukhosiniinikeza amapayipi ensimbi angenamthungo nahlanganisiwe ngokwezindinganiso ze-API, ASTM, EN, kanye ne-JIS. Uma unemibuzo mayelana nokukhetha amapayipi, zizwe ukhululekile ukuxhumana nethimba lethu lobuchwepheshe – silapha ukuzokusiza.
