I-Sch 40 vs. I-Sch 80: Yintoni umahluko?
Ukuqonda "uMgangatho" vs. "Ubunzima Obungaphezulu" ukuze kukhethwe ngokufanelekileyo isicelo.
Qaphela: Ububanzi obungaphandle (OD) buhlala bufana. Ubukhulu bodonga olongezelelweyo lweSch 80 bunciphisa ububanzi obungaphakathi (ID).
💡 Ingcamango ephambili: I-OD efanayo, i-ID encinci

| Uluhlu lweNdonga | umgangatho | Ityebile (+40-50%) |
| Uxinzelelo loxinzelelo | Eliphakathi (Amanzi/iGesi) | Phezulu (iiHydraulics/Umphunga) |
| Umthamo wokuhamba | UMqulu oPhezulu | Umthamo Owehlisiwe |

.️ Kutheni iSch 80 isetyenziselwa ukuQokelela imisonto?
Xa usika imisonto ibe yipayipi, ususa isinyithi eludongeni. Ishedyuli 80 ikhethwa kakhulu kwiintambo zonxibelelwano kuba nasemva kokusika imisonto, kusekho ubukhulu obaneleyo bodonga obuseleyo ukugcina ulungelelwaniso lwesakhiwo kunye nokuphathwa koxinzelelo. I-Sch 40 inokuba ncinci kakhulu emva kokufaka imisonto.
Uxinzelelo oluphezulu lokuSebenza
Kutheni iindonga ezijiyileyo zibalulekile. Uxinzelelo lwethiyori olusekelwe kwi-ASTM A106 Grade B.

🔥 Kutheni iSch 80: Ukumelana noxinzelelo lobushushuImibuzo ebuzwa qho
Imibuzo eqhelekileyo malunga nobukhulu, ukuwelda, kunye nokukhetha.
Ingaba i-Diameter yangaphandle (OD) yeSch 80 inkulu kuneSch 40?
Hayi. Ububanzi bangaphandle buyafana kuzo zonke iishedyuli zobukhulu obunikiweyo be-NPS. Oku kuqinisekisa ukuba zilingana nee-hangers zepayipi eziqhelekileyo kunye nee-flanges. Umahluko kukuba i-Sch 80 inodonga olutyebileyo, olunciphisa Idayamitha yangaphakathi (ID).
Ndingakwazi ukutshixa umbhobho weShedyuli 80 ukuya kwiSchedule 40 fittings?
Kuyenzeka kodwa nga khuthazwa kwiinkqubo ezinoxinzelelo oluphezulu. Ukungalingani kobukhulu bodonga kudala "inyathelo" ngaphakathi kombhobho, nto leyo ebangela ukuxinana kunye noxinzelelo. Kwizicelo ezibalulekileyo, soloko ufanisa ishedyuli yombhobho kunye nezixhobo (umz., umbhobho weSch 80 kunye nezixhobo zeClass 3000).
Kutheni i-Sch 80 ikhethwa xa kusetyenzwa ngemisonto?
Imisonto yokusika (i-NPT) isusa isinyithi eludongeni lombhobho. Iindonga zeSch 40 zihlala zincinci kakhulu emva kokuyidibanisa, nto leyo ewenza buthathaka amalungu. I-Sch 80 inika "inyama" eyongezelelweyo (ubukhulu bodonga) ukuze nasemva kokudityaniswa kwemisonto, udonga oluseleyo lube lomelele ngokwaneleyo ukumelana noxinzelelo.
Ngaba iShedyuli 80 isoloko ingenazingxaki?
Akunjalo rhoqo, kodwa kwiisicelo zoxinzelelo oluphezulu (ASTM A106), Ingenamthungo (SMLS) ngumgangatho. IShedyuli 80 eWelded (ERW) ikhona kodwa ayixhaphakanga kakhulu kwiipayipi zoxinzelelo olubalulekileyo. Soloko ujonga iinkcukacha (umz., Uhlobo lwe-A53 E vs Uhlobo lwe-S).
Ngaba "i-Extra Strong" (XS) iyafana neShedyuli 80?
Kude kube yi-NPS 8", Ewe. Kwiisayizi ze-NPS 1/8" ukuya kwi-NPS 8", iShedyuli 80 kunye ne-Extra Strong (XS/XH) ubukhulu ziyafana. Nangona kunjalo, kwiisayizi I-NPS 10" nangaphezulu, Iindonga zeSch 80 ziba nkulu kuneXS eqhelekileyo.
