Cabbirka Dhuumaha Magaca

Waa maxay Cabirka Dhuumaha Magaca?

Cabbirka Dhuumaha Magaca(NPS)waa cabbirka caadiga ah ee Waqooyiga Ameerika ee tuubooyinka loo isticmaalo cadaadiska sare ama hooseeya iyo heerkulka. Magaca NPS waxa uu ku salaysan yahay nidaamkii hore ee "Iron Pipe Size" (IPS).

Nidaamkaas IPS waxaa loo sameeyay in lagu qeexo cabbirka tuubada. Cabbirku wuxuu matalaa qiyaastii dhexroorka tuubada gudaha ee inji. Tuubbada IPS 6 ″ waa midka dhexroorkiisu yahay ku dhawaad ​​6 inji. Isticmaalayaashu waxay bilaabeen inay ugu yeedhaan tuubada 2inch, 4inch, 6inji tuubo iyo wixii la mid ah. Si loo bilaabo, cabbir kasta oo tuubo ah ayaa loo soo saaray inuu yeesho hal dhumuc, kaas oo markii dambe loo yaqaan heerka caadiga ah (STD) ama miisaanka caadiga ah (STD.WT.). Dhexroorka ka baxsan tuubada ayaa la jaanqaaday.

Maaddaama shuruudaha warshadaha ee wax ka qabashada dareeraha cadaadiska sarreeya, tuubooyinka waxaa lagu soo saaray derbiyo dhumuc weyn, kuwaas oo loo yaqaanno xoog badan (XS) ama culus (XH). Shuruudaha cadaadiska sare ayaa sii kordhay, oo leh tuubooyinka derbiga oo dhumuc weyn. Sidaa darteed, tuubooyinka waxaa lagu sameeyay derbiyo labanlaab ah oo xoog leh (XXS) ama labanlaab culus oo dheeri ah (XXH), halka dhexrooryada bannaanka ee caadiga ah aysan isbeddelin. Ogsoonow in mareegahan shuruudo kaliyaXS&XXSloo isticmaalo.

Jadwalka Tubooyinka

Markaa, wakhtiga IPS kaliya saddex darbi-jiif ayaa la isticmaalayey. Bishii Maarso 1927, Ururka Heerarka Mareykanka ayaa sahan ku sameeyay warshadaha waxayna sameeyeen nidaam u qoondeeyay dhumucyada derbiga oo ku saleysan tillaabooyin yar yar oo u dhexeeya cabbirrada. Magacaabidda loo yaqaan cabbirka tuubada magacaaban ayaa beddelay cabbirka tuubada birta, iyo jadwalka ereyga (SCH) waxaa la alifay si loo qeexo dhumucda gidaarka magaca ee tuubada. Marka lagu daro tirooyinka jadwalka heerarka IPS, maanta waxaan ognahay dhumucyada derbiyada kala duwan, kuwaas oo:

SCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS iyo XXS.

Cabbirka tuubada magaca ah (NPS) waa naqshadeeye aan cabbir lahayn oo cabbirka tuubada ah. Waxay muujinaysaa cabbirka tuubada caadiga ah marka ay raacdo lambarka cayiman ee cabbirka gaarka ah oo aan lahayn calaamad inch ah. Tusaale ahaan, NPS 6 waxay tilmaamaysaa tuubo dhexroorkeedu yahay 168.3 mm.

NPS waxay si dabacsan ula xiriirtaa dhexroorka gudaha injis, iyo NPS 12 iyo tuubada ka yar waxay leeyihiin dhexroor ka baxsan cabbirka naqshadeeyaha. NPS 14 iyo ka weyn, NPS waxay la mid tahay 14inch.

NPS la siiyay, dhexroorka dibaddu si joogto ah ayuu u ahaanayaa dhumucdiisuna waxay sii korodhaa tirada jadwalka oo weyn. Dhexroorka gudaha wuxuu ku xiran yahay dhumucda gidaarka tuubada ee lagu qeexay lambarka jadwalka.

Soo koobid:
Cabbirka tuubada waxaa lagu qeexaa laba tiro oo aan cabbir ahayn,

• Cabbirka tuubada magacaaban (NPS)
• lambarka jadwalka (SCH)

iyo xiriirka ka dhexeeya tirooyinkan ayaa go'aaminaya dhexroorka gudaha ee tuubada.

Cabbirrada Dhuumaha birta ah ee ay go'aamiso ASME B36.19 oo daboolaya dhexroorka dibadda iyo dhumucda derbiga Jadwalka. Ogsoonow in dhumucda gidaarada aan wasakhda lahayn ilaa ASME B36.19 ay dhamaantood leeyihiin "S" daba-gal. Cabbirrada aan lahayn daba-galka "S" waa ASME B36.10 kaas oo loogu talagalay tuubooyinka birta kaarboon.

Ururka Heerarka Caalamiga ah (ISO) waxa kale oo ay shaqaaleysiisaa nidaam leh naqshadeeye aan cabbir lahayn.
Magaca dhexroorka (DN) waxaa loo adeegsadaa habka halbeegga mitirka. Waxay muujinaysaa cabbirka tuubada caadiga ah marka ay raacdo lambarka cayiman ee cabbirka gaarka ah oo aan lahayn calaamad millimitir ah. Tusaale ahaan, DN 80 waa calaamad u dhiganta NPS 3. Hoos waxaa ku yaal miis u dhigma cabbirrada NPS iyo DN.

Fiiro gaar ah: NPS ≥ 4, DN la xidhiidha = 25 lagu dhufto lambarka NPS.

Hadda ma waxaad tahay waxa "ein zweihunderter Rohr"? Jarmalku waxay ula jeedaan in tuubada NPS 8 ama DN 200. Xaaladdan oo kale, Nederlandku wuxuu ka hadlayaa "8 duimer". Runtii aad ayaan u yaabay sida dadka dalalka kale u muujinayaan tuubo.

Tusaalooyinka OD iyo aqoonsiga dhabta ah

Dhexrooryada dhabta ah ee dibadda

• NPS 1 OD dhabta ah = 1.5/16 ″ (33.4 mm)
• NPS 2 OD dhabta ah = 2.3/8 ″ (60.3 mm)
• NPS 3 OD dhabta ah = 3½" (88.9 mm)
• NPS 4 OD dhabta ah = 4½" (114.3 mm)
• NPS 12 OD dhabta ah = 12¾" (323.9 mm)
• NPS 14 OD dhabta ah = 14 ″ (355.6 mm)

Dhexroorka dhabta ah ee tuubo 1 inji ah.

• NPS 1-SCH 40 = OD33,4 mm - WT. 3,38 mm - aqoonsiga 26,64 mm
• NPS 1-SCH 80 = OD33,4 mm - WT. 4,55 mm - aqoonsiga 24,30 mm
• NPS 1-SCH 160 = OD33,4 mm - WT. 6,35 mm - aqoonsiga 20,70 mm

Sida kor lagu qeexay, ma jiro dhexroor gudaha ah oo u dhigma runta 1″ (25,4 mm).
Dhexroorka gudaha waxaa lagu go'aamiyaa dhumucda gidaarka (WT).

Xaqiiqooyinka aad u baahan tahay inaad ogaato!

Jadwalka 40 iyo 80 ee ku wajahan STD iyo XS oo xaalado badan waa isku mid.
Laga soo bilaabo NPS 12 iyo wixii ka sareeya dhumucda derbiga ee u dhexeeya jadwalka 40 iyo STD way kala duwan yihiin, NPS 10 iyo wixii ka sarreeya dhumucda derbiga ee u dhexeeya jadwalka 80 iyo XS way kala duwan yihiin.

Jadwalka 10, 40 iyo 80 ayaa marar badan la mid ah jadwalka 10S, 40S iyo 80S.
Laakin ka fiirso, laga bilaabo NPS 12 – NPS 22 dhumucda derbiga xaaladaha qaarkood way kala duwan yihiin. Tuubooyinka leh dabadhilifyada "S" waxay leeyihiin calaamado derbi khafiif ah oo kala duwan.

ASME B36.19 ma daboosho dhammaan cabbirrada tuubooyinka. Sidaa darteed, shuruudaha cabbirka ee ASME B36.10 ayaa lagu dabaqaa tuubada birta aan-ka-soo-baxa ee cabbirrada iyo jadwalka aan lagu daboolin ASME B36.19.
