Ibha, i-MPa, i-PSI Kuya ku-PN10/PN16: Umhlahlandlela Ophelele Wokulinganisa Ukucindezela Kokufakwa Kwamapayipi

Lapho ukhetha ukufakwa kwamapayipi namavalvu, ukucindezela kungase kucaciswe kumayunithi ahlukene kuye ngemakethe noma izinga lamapayipi — Ibha, i-MPa, i-PSI, ne-kg/cm² konke kubonakala emidwebeni nakumininingwane yedatha, kuyilapho ukufakwa kwamapayipi epulasitiki kuvame ukuphawulwa ngamakilasi okucindezela afana ne- PN10 ne-PN16..

Ukwazi ukuthi la manani ahlobana kanjani namanye kusiza onjiniyela, abasabalalisi, nabathengi baqhathanise ukucaciswa ngokunembile futhi bakhethe ukulingana okulungile kohlelo lokusebenza — hhayi nje leyo enenombolo enkulu kulo.

Ibha, i-MPa, i-PSI kanye ne-kg/cm² Ithebula Lokuguqulwa

Amafomula okuguqula abalulekile:

• I-MPa = Ibha × 0.1

• Ibha = MPa × 10

• I-PSI ≈ Ibha × 14.5

• Ibha ≈ PSI × 0.06895

• Ibha ≈ kg/cm² × 0.9807 (vala ngokwanele kusilinganiso senkambu engu-1:1)

Isibonelo: ibha ye-16 = 1.6 MPa ≈ 232 PSI ≈ 16.3 kg/cm² - ukuguqulwa okufanele ukukhumbula ngekhanda, njengoba kwenzeka futhi ukuchaza isilinganiso se-PN16.

Isho ukuthini i-PN10 ne-PN16?

Ngokungafani neBar, i-MPa ne-PSI, okungamayunithi okucindezela, i-PN iwuhlelo lokuzisholo lwengcindezi olusetshenziselwa amapayipi, okokufakwa kanye namavalvu ngaphansi kwamazinga asekelwe ku-DIN/ISO.

Isinqamuleli esiwusizo: inombolo ye-PN iyinani lebha. I-PN10 ≈ 10 ibha, i-PN16 ≈ ibha engu-16. Kodwa akulona inani le-MPa — i-PN16 isho ukuthi i-1.6 MPa, hhayi i-16 MPa (i-16 MPa ingaba ngamabha angu-160, isigaba sokucindezela esihluke kakhulu).

I-PN akuyona ukuphela kwesistimu yokulinganisa ozohlangana nayo. Izilinganiso ze -SCH (Ishejuli) ngaphansi kwe-ASTM/ASME zichaza ukujiya kodonga kunokucindezela ngokuqondile, futhi i-SDR (Standard Dimension Ratio) isetshenziselwa amapayipi e-PE/HDPE ngaphansi kwe-ISO 4427. Akukho nokukodwa kokuthathu okungashintshaniswa ngokuqondile — i-spec exuba 'PN16' kanye 'kanye 'SCH80' kubha yezidingo ezifanayo kuqhathaniswa kokubili inani lenani le-MP.

I-PN10 vs PN16: Iyiphi Okufanele Uyikhethe?

I-PN16 akuyona inketho engcono ngokuzenzakalelayo. Isigaba esifanele sincike kokuthi:

• Ingcindezi yokusebenza ephezulu yesistimu

• Izinga lokushisa lokusebenza

• Ipayipi kanye nempahla yokufaka

• Uketshezi luyathuthwa

• Ukushintshashintsha kwengcindezi, isando samanzi noma ama-surges

• Izinga lamapayipi elisebenzayo lephrojekthi

Ingabe i-PN16 isho ukuthi Ukufaneleka Kungahlala Kuphatha Ibha engu-16?

Cha - futhi leli iphuzu abathengi abaningi abaliphuthelwa. Igama le-PN16 lisebenza ezingeni lokushisa eliyinkomba elicacisiwe, ngokuvamile elingu-20°C. Njengoba izinga lokushisa lokusebenza likhuphuka, ingcindezi yokusebenza evumelekile yezinto ezishisayo ze-thermoplastic ngokuvamile iyehla, ngakho-ke amanzi ashisayo asebenzayo afaka i-PN16 empeleni awabambi ibha yemajini engu-16 kuleso simo.

• I-PVC ilahlekelwa amandla okucindezela ngokuphawulekayo ngaphezu kuka-25–30°C futhi ngokuvamile ayinconywa ngesevisi eqhubekayo edlule ku-60°C.

• I-CPVC ibekezelela isevisi eqhubekayo efinyelela cishe ku-80–95°C (kuye ngebanga) kuyilapho igcina isigaba sokucindezela esiqathanisayo emazingeni okushisa amaphakathi - yingakho kuyindlela evamile yokuthuthukisa esuka ku-PVC emigqeni eshisayo.

• I-PE/HDPE ilinganiselwe nge-SDR kune-PN, ngezinga layo lokushisa kanye nejika lokucindezela elincike esikhathini.

Njalo hlola ishadi lomkhiqizi-vs-izinga lokushisa lezinto ezithile ngaphambi kokuphothula ukukhetha okusekelwe enombolweni ye-PN ephrintiwe iyodwa.

Ukukhetha Ukulingana Okulungile Ngekilasi Lokucindezela & Okubalulekile

• I-PN10 / PN16 PVC & CPVC - amanzi abandayo, ukuchelela, ukusatshalaliswa okujwayelekile eduze nezinga lokushisa elizungezile. → I-PVC Fitting PN10 | I-PVC Fitting PN16 | I-CPVC Fitting PN16

• SCH40 / SCH80 PVC & CPVC — ingcindezi ephakeme noma izinga lokushisa eliphakeme, ukucubungula amakhemikhali, amaphrojekthi ajwayelekile we-ASTM. → I-PVC Fitting SCH40 | I-PVC Fitting SCH80 | I-CPVC Fitting SCH80

• I-PE Fittings (SDR, ISO 4427) - amapayipi amanzi agqitshiwe, izintambo zegesi, amasistimu ahlanganisiwe. → Ukufakwa kwe-PE | Ukufakwa kwe-PE Socket Fusion

• I-PPH, PVDF & PFA Fittings — ukuhlanzeka okuphezulu noma imigqa yenqubo yamakhemikhali anolaka ngaphezu kwemikhawulo ye-PVC/CPVC. → Ukufakwa kwe-PPH | Ukufakwa kwe-PVDF | Ukulinganisa kwe-PFA

Amaphutha Okukala Ingcindezi Ejwayelekile

• Ibha edidayo ne-MPa. Amabha angu-16 ≠ 16 MPa — ahlukene nge-10.

• Ukuthatha i-PN16 njalo kusho ibha engu-16 yemajini yomhlaba wangempela. Isilinganiso siwukuhlukaniswa kwesithenjwa sesimo, akusona isiqinisekiso ngaphansi kwawo wonke amazinga okushisa noketshezi.

• Ukuziba isando samanzi. Ukuma kwephampu kungazelelwe noma ukuvalwa kwevalvu kungakhuphula ingcindezi ngaphezu kwengcindezi yokusebenza yesimo esiqinile, ngisho nasesistimu ebukeka iphephile ngaphakathi kwesilinganiso sayo se-PN ephepheni.

• Ukuxuba izinombolo ze-PN, SCH kanye ne-SDR ngokuqondile. Guqula yonke into ibe ibha/MPa ngaphambi kokuqhathanisa yonke imininingwane yephrojekthi.

Ungasikhetha Kanjani Isilinganiso Sokucindezela Esilungile

1. Nquma ingcindezi yokusebenza - thola ingcindezi evamile nephezulu yesistimu.

2. Hlola izinga lokushisa lokusebenza - kokubili okuvamile kanye nenani eliphakeme.

3. Khetha okokusebenza — i-PVC, i-CPVC, i-PPH, i-PE/HDPE, i-PVDF noma i-PFA, ngokusekelwe kuhlelo lokusebenza.

4. Qinisekisa izinga elisebenzayo — PN, SCH, SDR, DIN, ASTM noma JIS.

5. I-akhawunti yokwenyuka kwengcindezi — isando samanzi, izimo zokuqala/zokumisa iphampu.

6. Qinisekisa usebenzisa idatha yomkhiqizi — ungalokothi uqedele ukukhetha ekuguquleni okuyindilinga kuphela.
